Hydrostatic test automatic test system

Abstract

The invention discloses a hydrostatic test automatic test system, and belongs to the technical field of water hydraulic equipment testing. The hydrostatic test automatic test system is characterized in that an air source integrated control valve bank is sequentially connected with an air pump, a first air source reversing valve bank, a one-way valve, a container unloading valve, a high-pressure filter, a manual stop valve, a pressure sensor, an overflow valve, a pressure stabilizing tank, a high pressure pump, a motor and a water tank through connecting pipelines; the high pressure pump is connected with a pressure maintaining flat valve bank. A pressure relief device comprises a pressure relief flat valve bank, a second air source reversing valve bank, an electric throttle valve and a high-pressure sensor; the pressure maintaining flat valve bank and the pressure relief flat valve bank are connected in parallel; a high-pressure input interface, a high-pressure output interface, a pressure relief input port and a pressure relief output port are fixed on the rack, and the electric throttle valve and the high-pressure sensor are respectively connected with the pressure relief input port. The pressure resistance of various pipelines, high-pressure and low-pressure pressure vessels and equipment can be tested, and the system has the characteristics of high pollution resistance, high pressure maintaining precision, safety and reliability in testing and long service life.

Description

Technical field [0001] The invention relates to the technical field of water hydraulic equipment testing, in particular to a water pressure test automatic test system. Background technique [0002] In order to ensure the safe and reliable performance of hydraulic equipment, all kinds of pipelines, pressure vessels, valve bodies and various connecting parts need to be pressure tested, and can be used only after passing the test according to the inspection standard. In the existing hydraulic equipment, in order to solve the high pressure problem of the hydraulic equipment, most of the corresponding pipelines are equipped with pressure maintaining valves and pressure relief valves to achieve the effects of pressure maintaining and pressure relief. [0003] For example, the Chinese patent document with the publication number CN 103603834A and the publication date on February 26, 2014 discloses an automatic pressure maintaining device, which has an oil inlet, an oil outlet, a pressure h...
