Providing pressurized liquid to a hydraulic drive hydraulic components of the hydraulic pump (domestic maintenance), is a pump. Its function is to power machine (such as a motor and an internal combustion engine, etc.) of the mechanical energy into pressure energy of the liquid. Many factors affect the life of the hydraulic pump of the hydraulic pump (domestic maintenance), in addition to the pump itself design, manufacture and some external factor selection element associated with the use of the pump (such as couplings, filter, etc.), the operation of the test procedure operation also has a relationship. A variety of hydraulic pumps and motors are using the "sealed volume (chamber)" cyclical changes to work. Working in both the need for auxiliary devices such as valve plate hydraulic pump (domestic agents), and that "sealed volume" is divided into two separate parts high and low pressure areas. Both at work will produce the phenomenon of trapped oil and radial force imbalance, hydraulic shocks, flow pulsation and fluid leaks and some common physical phenomena.
