Embodiment

[0028] The oil tank hydraulic performance test bench is composed of three parts: hydraulic system, measurement and control system and bench body.

[0029] The hydraulic system can be applied to low-pressure system, high-pressure system, impulse cylinder system and pressure-resistant system, and can be tested independently. The hydraulic system of the fuel tank performance test bench is an open system, and the hydraulic system can realize internal leakage test, pressure test, static friction test, no-load and full-load work test, volume test, endurance life test, test of pressure relief valve work, low-pressure safety valve performance test. The hydraulic system has self-cleaning function. The oil inlet and outlet of the oil tank adopt a universal adapter, which can directly connect the oil inlet of the test bench to the oil return port, and the longest pipeline can be self-cleaned. Multiple exhaust valves are installed in the hydraulic system to facilitate the discharge of a...

Abstract

The invention discloses a phosphate ester oil hydraulic oil tank performance test bench, which comprises a high-pressure system, a low-pressure system, an oil temperature control and self-cleaning system, a measurement and control system and a platform; the high-pressure system is used to adjust the pressure and flow of a booster chamber; It is used to adjust the pressure and flow of the oil storage chamber; the oil temperature control and self-cleaning system is used to realize the hydraulic oil temperature control of the hydraulic system and the self-cleaning ability of the oil; the measurement and control system is mainly used to realize the parameter adjustment of the hydraulic system, data Acquisition and processing and power distribution protection; the platform is used to install the test piece. The invention can complete the test and measurement of performance parameters such as the flexibility and running-in of the pressurized oil tank, functional inspection, oil storage chamber pressure and pressure resistance, flow impact and the like stipulated in the standard.

Description

technical field [0001] The invention relates to the technical field of pressurized oil tanks, in particular to a performance test bench for phosphate ester oil hydraulic oil tanks. Background technique [0002] Whether the working performance of the pressurized fuel tank meets the technical requirements directly affects whether the aircraft hydraulic system can work normally, and even leads to major flight accidents. Therefore, the pressurized fuel tank is one of the key accessories for regular maintenance by the user. [0003] Yang Chao and others proposed a hydraulic system pressurized fuel tank test bench in "Design of a certain type of aircraft hydraulic system pressurized fuel tank test bench". The pressurized fuel tank test bench is composed of a hydraulic pump station, a performance test part and an electrical control part. Test determination of performance parameters such as flexibility and running-in of pressurized oil tank, function inspection, oil storage chamber ...
