Abstract

The invention provides an axial plunger pump with oil leakage measurement, and relates to the technical field of plunger pumps. The axial plunger pump comprises a main body housing and a variable housing, wherein a joint of the main body housing and the variable housing is equipped with a channel for enabling the inner cavity of the variable housing to be in fluid communication with an oil leakagehole of the axial plunger pump; a flow measuring device is arranged in the channel; and the flow measuring device is used for measuring flow of leaked oil which flows through the channel. According to the axial plunger pump provided by the invention, the flow measuring device is arranged in the oil leakage channel, so that flow of leaked oil which flows through the channel can be measured in realtime, and therefore, when flow of leaked oil is abnormal, an operator can timely takes corresponding measures for the axial plunger pump, the inner cavity of the variable housing is prevented from anoil trapping phenomenon, and the service life of the axial plunger pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to an axial plunger pump with oil drain measurement. Background technique [0002] A conventional variable displacement axial piston pump includes a main body casing and a variable displacement casing. Oil in the housing cavity can drain through this channel to the oil drain port. [0003] The conventional variable axial piston pump cannot measure the flow of oil drained in the drain channel in real time. Therefore, when the drain oil flow in the drain channel decreases due to blockage of the drain channel or other faults, the high In the case of rotation and high pressure, it is easy to increase the pressure in the cavity of the variable housing, resulting in oil trapping, which reduces the service life of the pump itself. Contents of the invention [0004] The object of the present invention is to provide an axial piston pump with oil drain measurement to solve the probl...
