Hydraulic Pumps are highly utilized parts in a forklift. For example, hydraulic pumps can be found in the power steering system, braking system, suspension system, and gear and motor system. The focus of the following article refers to the hydraulic pumps in gear and motor systems.
Forklift Hydraulic Pumps found in the gear and motor systems provide the flow required to transmit power to a hydraulic actuator from a prime mover. There are two types of hydraulic pumps; centrifugal and positive displacement. Centrifugal involves the flow of the fluid transfer, which depends on the outlet pressure. Whereas, the positive displacement depends independently on pressure. The hydraulic flow is created when the prime mover drives the pump rotating group, which forces fluids out of the pump outlet. When the fluid is forced out, a vacuum force is made at the pump inlet and its natural pressure pushes the fluids from the reservoir into the pump.
Positive displacement pumps come in two forms: fixed displacement and variable displacement. Fixed displacement (hydrostatic) pumps have the flow varying only on the shaft speed. Its benefit is that it performs well, creating a constant flow and pressure. Variable displacement (hydrodynamic) pumps can have flow varying on any shaft speeds provided. Though variable displacement is the more expensive alternative of the two, it is more energy efficient. Also, it performs well for variable flow or pressure applications.
Bad Gear Problem on a Hydraulic Pump
A common hydraulic pump problem is one with bad gears. The bad gear problem may occur for various reasons such as wear, high temperature of the hydraulic fluid, fluid leaks and contamination, and aeration which occurs due to air pockets. Checking the hydraulic pump gears is as follows:
If the findings from the above steps concludes that the components are damaged are worn out, they have to be replaced. Solid Lift Parts Inc. provide hydraulic pump components for all makes and models for inexpensive prices. The hydraulic pump and its components should be replaced by a professional mechanic with expertise in hydraulic pump replacement.
