Proper functioning of Clark forklift’s hydraulic system is necessary to perform lift and tilt operations whenever needed. This article covers the working of lift truck hydraulic pump, how to select a hydraulic pump for your Clark forklift trucks and ways to repair and maintain the same.
Hydraulic System Components
The hydraulic system of Clark lift trucks is made of the following components:
The lift circuit in the system comprises of: control valve, lift cylinder, velocity fuse, one way restrictor, service port release valve (one in the rod end and one in the piston end), and valve lift section.
The title circuit is made of: control valve, left hand tilt cylinder, right hand tilt cylinder, anti-cavitation valve, one way restrictor, and tilt valve section.
Hydraulic Pump Components and Operation
Following are the various components that together form Clark forklift hydraulic pump:
This is how the hydraulic pump works:
Hydraulic Pump Selection
As there are several different types and makes of forklift hydraulic pumps available in the market today, selecting the right pump for your Clark lift trucks to get optimum performance from your truck’s hydraulic system is definitely not as easy task. Following are the various factors you should take into consideration when selecting a hydraulic pump for your Clark forklift’s hydraulic system.
o If you choose hydraulic oil with low viscosity, you will end up increasing the rate of internal leakage in the pump, which will further decrease its efficiency. Also, internal leakage of the whole hydraulic system will increase, reducing its efficiency as well.
o On the contrary, if viscosity of the oil is very high, the hydraulic pump will not be able to draw fluid, which will result in cavitation, reduction in overall system efficiency and reduced usable power.
The hydraulic pumps offered by Solid Lift Parts are highly efficient and less costly. We have pumps for all makes and models of lift trucks, and we also provide convenient delivery options.
Additional notes (30-09-2015) -
Clark Forklift Hydraulic Pump is the most used component in a Clark forklift. It is mostly found in the suspension system, braking system, power steering system, and gear & motor system. To accomplish the operations of lift and tilt, according to the requirements, perfect functioning of Clark Forklift Hydraulic Pumps is very important.
Transmission of the power coming from a prime mover to a hydraulic actuator is a major function of a Clark Forklift Hydraulic Pump. These pumps come of two types- centrifugal and positive displacement pumps. The centrifugal pump deals with the transfer flow of fluid, which is completely dependent on the outlet pressure; while pressure is the main regulator of the positive displacement pumps.
When the Clark Forklift Hydraulic Pump is held in position by the hydrostatic pump, a coupling moves directly to both of the pumps. As both the drive and driving gears rotate, oil after reaching the inlet port is transferred. Eventually, the circuit loads create a pressure. To settle a minimum gap between the gears and the bearings, a pressure compensation area is there inside the pump. An E-shaped seal moves the pressure to the bearing blocks for balancing them against gears.
If lower viscosity oil is used, it may create leaks in the pump and thus may affect on the performance of the pump. A high viscosity oil may disable the pump to draw fluid, which may end up in cavitation. The high temperature of the hydraulic fluid, abrasion, fluid leaks and aeration may cause problems in the gears, that may cause harm to the pump. In case of damaged parts, emergency replacement and routine maintenance is very important for improved performance of the forklift trucks.
