Abstract

The invention discloses a plateau-type aviation hydraulic oil pump vehicle which is connected to an oil inlet and an oil outlet of an aircraft hydraulic system; the aviation hydraulic oil pump vehicle comprises an automobile chassis, a compartment, a hydraulic system, a power transmission system, an electrical control system and a remote monitoring system. The device of the invention has comprehensive functions, and generally two sets of independent hydraulic systems are arranged on the oil pump vehicle; the device is mainly used for testing aircraft hydraulic system ground performance, purifying the aircraft hydraulic system oil, providing and adding hydraulic oil for the aircraft hydraulic system, on-line detecting oil solid particle pollution degree, vacuuming and removing water for the oil and remote monitoring and controlling, fault diagnosis and decision-making.

Description

technical field [0001] The invention relates to the field of ground support equipment for aircraft hydraulic systems, in particular to a plateau type aviation hydraulic oil pump vehicle. Background technique [0002] Modern aircraft generally have a hydraulic system. When testing and maintaining the hydraulic system of the aircraft on the ground, ground oil pump equipment is needed to complete the performance testing of the aircraft hydraulic system. The aviation hydraulic oil pump truck is mainly designed to meet this requirement. of. [0003] The aviation hydraulic oil pump truck provides a hydraulic power source for the aircraft hydraulic system with a certain pressure, flow rate and working medium (aviation hydraulic oil) that meets the pollution level requirements when the aircraft engine is stopped. It is an important aircraft ground support equipment. one. The main functions of the aviation hydraulic oil pump truck include aircraft hydraulic system performance testi...
