Electro-hydraulic high-pressure test system and test device

Abstract

The invention discloses an electro-hydraulic high-pressure test system and a test device. The test device comprises an electro-hydraulic high-pressure test system and an electric control power cabinetwhich are fixed on an engine base, and the electro-hydraulic high-pressure test system comprises an electric test system and a hydraulic station control system; the electric test system comprises anelectric pump set and a flat valve set, the electric pump set comprises a motor, a pump seat, a coupler and an electric pump, the flat valve set comprises an electric pump, a high-pressure overflow valve, a high-pressure tubular one-way valve, a plurality of valves and the like which are connected through a high-pressure pipeline, and a tested piece is connected to a high-pressure output interfaceof the flat valve set; and the hydraulic station control system includes a plurality of components and a plurality of interfaces connected by connecting lines. By means of the flat valve set, a high-pressure pressure gauge, a pressure gauge and an energy accumulator pressure gauge, test pressure can be controlled, various test conditions can be simulated, the advantages of being stable in pressure maintaining, convenient to relieve pressure, reliable and durable are achieved, test operation is easy, the pressure measurement cost can be effectively reduced, and the pressure measurement efficiency is improved.

Description

technical field [0001] The invention relates to the field of water hydraulic equipment testing, in particular to an electro-hydraulic high-voltage testing system and a testing device. Background technique [0002] In order to ensure the safety and reliability of hydraulic equipment, all kinds of pipelines, pressure vessels, valve bodies and various connecting parts need to be tested for pressure resistance, and can only be used after passing the test according to the inspection standard. At present, high-pressure needle valves are often used for pressure maintenance and pressure relief, and their service life is short. In addition, the test medium contains more impurities and is easy to be damaged. This not only causes test failure, but also has a certain impact on the safety of workers. [0003] Therefore, it is necessary to design a system that is simple, safe and reliable, has strong anti-pollution ability, high pressure holding accuracy, and long service life, and can me...

AI Technical Summary

Problems solved by technology

At present, there are many high-pressure needle valves used for pressure maintenance and pressure relief, which have a short service life, and the test medium in the test contains more impurities and is easy to be damaged, which not only causes the test to fail, but also has a certain impact on the safety of workers.
