Your lift truck needs power to move the mast up and down and its forklift hydraulic parts that provide the muscle. If the engine is the heart of your forklift, hydraulic fluid is its blood. Hydraulic cylinders are attached to the mast and cause it move up or down depending upon the pressure in the cylinders. A hydraulic pump brings hydraulic fluid into the bottom of a cylinder barrel which holds a piston. The fluid forces the piston in the cylinder to move up and down or back and forth. A lift cylinder handles the lifting mechanism while a tilt cylinder enables the forks to tilt sideways when necessary.

The main parts of the hydraulic cylinder are the cylinder barrel, a cylinder base and cap, the cylinder head, the piston and piston rod, and the rod gland which contains various O-rings and seals including one that wipes off dirt from the piston rod when it moves back into the cylinder. The two types of hydraulic cylinders are the tie rod cylinder and the welded body cylinder. The welded body cylinders are narrower and shorter than the tie rod variety. For this reason, most forklift trucks and other mobile equipment prefer the welded body hydraulic cylinders.

The troubleshooting and inspection of hydraulic cylinders for most brands like Clark, Hyster or Toyota trucks are basically similar. This process for a Yale forklift is a good example:

With a clean cloth, you should wipe down the rods then raise the forks. If there is more than a thin coat of oil on the rods, the seals may be worn out and need to be replaced. Next check the hydraulic fluid level visually or with a dip stick. If it is not full, air will enter the cylinder and damage the seals within and cause the forks to jerk while moving. If the forks continue to jerk even when the hydraulic fluid is full, the hydraulic fluid pump may be clogged or damaged. Wipe off the hoses and lines. Move the forks a few times and check for leaks on the hoses themselves or in the connections.

Oil leaks in the hydraulic system are the main symptom of damage and show that it’s time to replace forklift hydraulic parts. In general, oil leaks will result in insufficient oil and lead to deterioration of parts. Check for leaks in the hydraulic control valve. Incorrect hydraulic pressure can contribute to leaks, damage seals and reduce the truck’s lifting capacity. In the lift cylinder, leaks can cause load drift problems and contaminate the operating environment. Tilt cylinder leaks will result in uncontrolled mast movement. Hydraulic hoses can be damaged by bent sheaves while a clogged hydraulic filter will interfere with good oil flow and increase the truck’s system pressure. Defective hydraulic cylinders in the steering system can result in steering loss and hasten the wear and tear of hydraulic parts.

Hydraulic fluid is a favorite way of providing muscle with low pressure input. Proper maintenance of your forklift hydraulic parts will make sure that you have all the power you need all the time.

Hydraulic pumps convert mechanical energy and motion into hydraulic fluid power. The basic idea is very simple: force that is applied at one position is transmitted to another position using an incompressible fluid, like oil, which cannot be compressed but rather is displaced when pressure is applied.

A reservoir, a hydraulic cylinder, and a pump make up the three main parts of a hydraulic pump. Pumping hydraulic fluid from the reservoir into the bottom cavity of the cylinder causes the piston rod to be pushed up, which pushes the fluid in the other cavity back into the reservoir. This procedure pressurizes the chamber and extends the piston to its full length. Pumping hydraulic fluid into the upper chamber of the cylinder pushes the piston rod down, pushing the oil in the other chamber back into the reservoir, completing the cycle.

Popular Hydraulic Pump Types

Vane pumps, piston pumps, and gear pumps are the foremost types of hydraulic pumps
Gear pumps - uses gears to pump fluid by displacement. Hydraulic gear pumps are one of the most common types of pumps. There are several advantages and disadvantages to gear pumps. The advantages are: high speed, high pressure, and quiet operation. The disadvantages are: the use of four bushings in the liquid area and fixed end clearances.
Rotary vane pumps - are positive-displacement. They include a ring mounted inside a cylindrical case. There are a number of radial slots in which sliding vanes are located. Mounted to the case is the ring and the vanes are designed to press against the inside wall of the case. Hydraulic pressure or spring force or centrifugal force as the ring is rotated will cause the vane to be forced against the wall.
Axial piston pumps - are positive displacement. There are several pistons in a circular arrangement in a cylinder block.
Radial piston pumps - a circular arrangement of hydraulic pistons, and valves which allow pressures greater than 650 Bar (~10,000 psi) to be built.
Screw pumps - positive displacement pumps. Have one or more screws that rotate to transfer high or low viscosity fluids along an axis.

Hydraulic pump works on principle of converting the mechanical energy and motion into hydraulic fluid power. These are capable of rotating and acting just like a motor. These are usually powered by gas or electricity and also hand and air driven can also be found or utilized. In the fluid power industry there are three main types of these machinery used, which are basically the namely vane, gear, and piston pumps. One will find two different kinds which are used in hydraulic drive systems, these are hydrostatic and hydrodynamic. The major differences between the hydrostatic are that these are positive displacement models while hydrodynamic are typically fixed of variable displacements.

These are the usual types which include gear, rotary vane, screw, bent axis, radical piston and axial piston Swashplate principle.

Gear: This type comes with a fixed displacement and external teeth and is suitable for pressures below 3000psi. These are simple to operate, come cheap and are durable. The major cons of a gear model is that it has a limited pressure capability, unbalanced results in large bearing loads, can be noisy and because it is working at a constant displacement, their work is less efficient.

Vane: This type is chiefly driven by an outside engine that rotates at a continuous speed. Similar amount of fluid is pumped with each rotation, which is regardless of how much pressure there is in the system. Its major advantages are reliability and simple operation. One will certainly find an option of variable displacement and this type has a higher pressure capability as compared to the gear type, as it operates in pressures up to 180 bars. Expensive and more complex are the two major disadvantage of this particular type.

Axial Piston: This particular type contains pistons that are arranged in a circular array within a cylinder block, which serves as its housing. It has a variable design and contains the highest volumetric efficiency and pressure capability. These are the two prime advantages of this type. These work well for pressure up to 350 bars. It is more sensitive to oil contamination and is expensive; these are few inconveniences one will encounter with this model.

Radial Piston: The Radial Piston pumps are in disparity with axial piston types. These contain pistons that are arranged in symmetrical and radial direction around a drive shaft. The major benefits of these are highly reliable, works efficiently and are capable to create minimum level of noise. This type operates through pressures around 650 bars. Its bigger radial dimensions and higher cost are few drawbacks of this type.

Buying Guide:
Before selecting any type of hydraulic pump, it is essential to consider few very necessary points like operating pressure, temperature and its frequency. There are less expensive, low-pressure models which are will certainly provide satisfactory solutions to several applications that require minimal pressures (less than 200 psi). This type should not be considered for heavy industrial operations.

Maintenance Requirements:
Increasing complexity of these modern hydraulic machineries has led not only to higher performance and operating pressures, but have also affected on the bills at any break down event. One has to be pro-active in maintaining and checking the needful for the smooth operation of these hydraulic pumps and motors. Here is the routine maintenance checklist to maintain these hydraulic machineries.

The hydraulic gear pump is an amazing invention that can be used to any construction machine that can carry heavy loads. Just imagine the strength of this kind of equipment. It can be used even in car brakes.

The idea behind the hydraulic system is quite simple. The force being manipulated in a certain point is transferred using fluids (specifically oil fluids) that can be compressed to push the other gear.

A good example to this is: Two pistons with a fluid inside. When a force is applied on the first piston, the other piston will be pushed up because the force of the other piston exerts pressure with the fluid hence the 2nd piston will move upwards.

The basic design is a gear pump is placed in an airtight or vacuum cylinder or casing. Another gear is placed outside the casing to add reinforcement to the seal. A smaller gear is placed inside to be used as a force to push the fluid inside creating an upward and downward movement.

As the suction ports are meshed together, there will be three gaps wherein the other gap will have an opening to let the fluid flow out. A motor is the attached to the gears to manipulate the process of hydraulic pump.

Remember that it is very important that there should be no air bubbles in a hydraulic pump. It is best to "bleed" the machine first so that the maximum efficiency of the hydraulic equipment is attained.

There is a lot of fluid oil that is used in heavy equipment. The hydraulic oil needed to pump the gears can range up to 100 gallons. This is not surprising especially if there are six to eight pumps in a single heavy equipment machine.

These hydraulic pumps can be fitted to any kind of machines and this includes a dump truck. This kind of heavy equipment machine is not quite complicated than the other machines. Usually, it needs only about 1 or 2 cylinders to drive the gear pumps.

The cylinder of the dump machine truck is quite unique because it moves just like a "telescope". Meaning, the cylinders can push up from the largest to smallest cylinder. It also doesn’t need a lot of force to push the heavy load since it only uses 1 to 2 cylinders.

The set up of the gear pump equipment in a dump machine works just like any other heavy equipment machines. Levers, clutch pedals and gear sticks are the basic set up to run the hydraulic pump.

It is very important to follow the basic steps in running the equipment so that it will properly run and the gears will not be damaged when used. Maintaining the fluid oil should also be done so as not to damage the cylinders. It is best to ask the help of an expert hydraulic mechanic so that the pumps are properly maintained and it will last longer.

Sump pumps are your first line of defense to keep water out of your basement. They also protect your foundations and the structural integrity of your house.

You will need it most in early spring when there is a lot of snow melting or in the summer when there are some heavy rains. It is going to be called upon more so them, so you should check the operation before it is too late. By the time you look to call on the pump it might not have run for some time. So you need to plan ahead and ensure your pump will run when needed and not have you arriving home to a flooded basement.

Sump pump maintenance will take no more than around 10 minutes to complete and you will need to check the operation of your sump pump and ensure it is there for you whenever you need it.

Tips for sump pump maintenance

Keep a cover over the sump basin.

• This will keep out animals and children as well as ensuring you do not have any debris falling into the basin.
• A cover will also reduce the smells and evaporation

Inspect for debris

Inspect the basin/sump for any debris and remove any you might find before operating the pump. We do not want this to get into the sump pump intakes or even block the pump. So,always ensure you remove the debris first before you test the pump.

Check pump screens/ Inlet screens

Check the inlet screens on your pump are free from debris and residue build up, as if they are blocked up this will reduce the operational efficiency of your sump pump.Therefore this will reduce the volume of water the pump removes which will be a lot less than it is designed to pump. If needed bring a hose and wash down the external of the sump pump as well as the basin to remove all debris that may affect the operation of the pump.

Electricity and safety

As there is electricity and water within the same installation you should ensure you are electrically protected using a ground fault indicator (GFI). This should keep you safe as it should trip the electricity if there is a fault. Check the operation of this if there is a test facility to do so.

Cable routing

Check for correct cable routing as well as the cable being in good condition. Make sure the cable is away from the water as much as possible. Also check the cable is secured and not loose and in a situation where it might fall into the sump. This could prove lethal and have happened in some rare circumstances. So check the cable is fixed and secure.

Check your discharge pipes

Always have a check valve fitted, this is to stop the pumped water within the discharge pumped line from returning into the sump and refilling the sump once pumped away. It only allows the water to move in one direction, which of course is out of your sump. If this is faulty you will see your sump re-filling and your pump will run more frequently.

Check the discharge line for leaks or damage. Make sure all is intact including the end of your pumping line. If you are able to visually see the pumped line ensure the end is free to allow the pumped water to properly run clear.

Water test your pump

Fill the sump with water very slowly and observe the operation of the sump pump. This way you can watch the operation of the float switch, ensure it rises with the water level and moves easily and freely.

Check the operation of the float switch

Once the float rises to the switch on point you want to observe the sump pump running. You should of course listen to the pump as well. What you are listening for in this case is the connection of the float switch and that the switch makes without any hesitation or resistance and runs the pump properly. As the float switch is considered one of the weak points of a sump pump you can observe this in this test and ensure your switch operates normally. If the switch is intermittent or not operating normally you may be able to replace the switch and not need to buy a replacement sump pump.

Listen to the pump

Now the pump is running you want to listen to the pump itself running. Make sure there are no squealing or grinding noises or even metal on metal. With the sump pump running there should be some minor vibrations, if there are excessive vibrations then you must investigate this. Excessive vibration or noises may indicate the bearings or internal workings of the pump may be wearing out. In cases like this it might be best to have a replacement sump pump near hand in case you have to replace a pump in a hurry.

Operate the pump several times

Operate the pump like this several times just to get the pump operating efficiently and also check that the sump pump also stops pumping whenever the water level is pumped down to a suitable level and the switch has returned to a resting position. In general what you are doing is checking complete cycles of the sump pump to check it is working as it should do when it might be needed.

Check Valve operation

Listen for the check valve click as well within this operation sequence; you want to hear the check valve operating as the pump stops pumping. The check valve should close with a click and stop the water from returning into the sump.

Points to consider for the maintenance of your sump pump and pump installation
• Keep a cover over the sump basin.
• Inspect for debris
• Check pump screens/ Inlet screens
• Electricity and safety
• Cable routing
• Check your discharge pipes
• Water test your pump
• Check the operation of the float switch
• Listen to the pump
• Operate the pump several times
• Check Valve operation
• Replace all covers and parts

Once you are happy with the operation of your sump pump and you have checked everything over you needs to ensure you replace all parts and covers into their correct location for the operation of the pump. You should also periodically check in on your sump pump just to ensure it will be there for you whenever needed.

Buying a heating and cooling unit has become necessary these days to keep up with the extreme weather conditions. And if you are already considering buying these two, why not just spend for heat pumps? These technological devices perform the function of both a heating and cooling unit. Thus, you would not only save big bucks on your initial purchase, you would also be able to cut on your electric bills in the long run.

But what exactly are these equipment and how do they work? Here are some basic information you should know.

Heat pumps are devices which combine the function of both a cooling and a heating unit. It is a form of technology which uses a little amount of energy in order to move heat from one place to another. It uses sources that are readily available in your immediate environment. C101/C102 Hydraulic Gear Pump For Dump Truck They generate warm air through pulling heat out of the air or ground. On the other hand, cool air is produced through switching them in reverse.

Another good thing about these devices is that they are actually energy efficient. For one, they are more efficient as compared to furnaces because instead of fuels, they merely transfer heat from one area to another. You not only cut back on your electric bills, you also become instrumental in the move to conserve energy. But because of this characteristic, they work best in moderate climate.

So how exactly do these devices work? Basically, it extracts heat available in your immediate surroundings. Then it pumps it inside your home or office. So essentially, there are two principles involved here. First, there is a movement from one hot object to a cool object. Then a pressurized gas that is allowed to expand becomes cool.

They are also made up of the same fundamental components that make up a refrigerator. First, there are coils to carry refrigerant gas. Then there is a compressor that will increase the pressure of the gas. And finally, there are fans that will circulate the air.

But before you go out to buy a heat pump, it would be best to read heat pump reviews first. This way, you will learn about the different specs of the various models. Then you will be able to decide which model will suit your needs and preferences. You can also look at the heat pump ratings. You can consult contractors about this or you can also ask your trusted appliance store.

Another factor you must consider when buying these types of equipment is the brand. And one of the trusted brands is Trane. In fact, a lot of reviews say that a Trane heat pump is the most reliable as compared to its contemporaries.

However, you must always bear in mind that proper installation is also important. This is for you to make the most out of your devices. As with any other device, if you do not install them properly, they will not function properly as they are designed to.、

Let’s face it. We all want muscles to grace our bodies, be it on the stomach, arms, chest and legs. After all, muscles are very good to look at as well as indications of healthy living. And who does not want to attract the opposite sex with just the right kind of muscles?

Still, you might despair because muscles do not pop up the minute hydraulic vane pump you want them to. You have to eat the right diet, perform the right exercises and follow a healthy lifestyle in order to gain the muscles you so dearly desire. Fortunately, you can have muscles with the following exercises that can be performed in mere minutes a day.

Chest Pump
If you are going out on a date and you want instant muscles, so to speak, then supersets of the chest pump are for you. Basically, each superset contains the following one-minute exercises:
•Perform as many push-ups as possible in one minute
•Then move on into the modified push-up position, with your knees on the ground, and perform the push-ups for as many as you can for just one minute
•Hold yourself about 5 centimeters off the floor for as long as you can or for 20 seconds, whichever makes your muscles burn the fastest

Remember not to rest in between the movements. Your goal is to repeat the supersets for at least 2-5 times. If you can make it more than 5 times, then you are resting longer than necessary.

Arm Pump
You also want to work out your biceps and triceps in equal measures. Although the upper arm consists of 40 percent biceps and 60 percent triceps, it is necessary to aim for a balanced look, thus, the need for these two arm pump exercises. This time, however, you must rest between exercises.

First, you must perform the bench dip. You should place your feet on a bench in front of you and your hands behind you on another bench behind your back. Now, ask a spotter to slowly place a few weight plates on top of your lap, which should be placed as steadily as possible so that these do not fall off.

Now, you need to lower your body until such position that your upper arms are almost parallel to the floor. Then, pause for one second and return to the starting position. You will be fatigued as you perform the set, during which time the spotter should slowly remove the weight plates until you can only carry your own bodyweight.

You will then place your feet flat on the floor and your knees bent. You should then lower your body to the floor for as many times as you possibly can.

Second, the dumbbell curl is good for your arms, too. You perform the basic dumbbell curls except that you have to alternate the three sets of 8-12 sets with preacher curls after a 5-minute rest.

In either of these curls, you have to start with 80 percent of your maximum weight and then slowly remove the weights until 10-15 percent. You should also rest between sets.

These simple workouts are very simple to do but are very effective in providing the muscles you desire. All these for just a few minutes a day!
