[0002] A hydraulic pump is a hydraulic component that provides pressurized liquid for hydraulic transmission. It is a type of pump. Its function is to convert the mechanical energy of a power machine (such as an electric motor and an internal combustion engine) into the pressure energy of a liquid. There are many factors that affect the service life of a hydraulic pump. In addition to the design and manufacturing factors of the pump itself, it is also related to the selection of some components related to the use of the pump (such as couplings, oil filters, etc.), and the operation during the test run. When the hydraulic pump is working, in order to determine its accurate working parameters, the hydraulic pump needs to be experimentally determined on various test benches during use.
