Abstract

The invention discloses a debuggable movable hydraulic oil source. The debuggable movable hydraulic oil source comprises a hydraulic pump, a motor, a check valve, an oil filter, an overflow valve, a speed regulation valve, a throttle valve, an electric heater, a pressure sensor, a temperature sensor, a three-way ball valve, a flow sensor, a heat exchanger, a proportion water valve, a liquid level meter, a cut-off valve, an air filter, an oil tank and an oil tube, wherein all the components are connected by the oil tube and tube joints; the three-way ball valve is adjusted, and the pump motor and the electric heater are started to carry out self-circulation heating for oil in an oil tanker; then the three-way ball valve is adjusted, the throttle valve and the speed regulation valve are adjusted to adjust a system flow to a target value, a target temperature value is input in an operation interface, and then various tests are carried out on the tested equipment. The source disclosed by the invention solves the problem of low or nonadjustable accuracies of parameters of an oil source pressure, a flow, a temperature and the like of a heat exchange test.

Description

technical field [0001] The invention relates to a hydraulic oil source, in particular to a movable hydraulic oil source which can be adjusted. Background technique [0002] The working medium of the current aircraft hydraulic system requires that the long-term working temperature should not exceed 100°C (short-term 125°C) under any working conditions, and the hydraulic system will generate heat due to power loss when it is working, and the heat will be transferred to the working medium, making the system The temperature rises, which may cause the system working medium temperature to be too high. Excessive temperature of the hydraulic system is one of the important causes of hydraulic system failure, which seriously affects the safety of the system. Therefore, it is necessary to take necessary heat dissipation and cooling measures. The aircraft hydraulic system generally adopts the fuel-hydraulic oil heat dissipation method, which can effectively meet the heat dissipation r...
