A New Braided Hose Pressure Testing System

Abstract

The invention discloses a novel braided hose pressure testing system. The test system is composed of a water tank, a water pressure control system, an air pressure control system, a control box and a test bench body, etc.; when the test system is working, the self-priming pump (15) of the water pressure system passes the water in the water supply tank (12) through the water supply valve (13), filter (14), one-way valve (16) are pressed into the brake hose circuit pressure stabilizing cylinder (7), total wind hose circuit stabilizing cylinder (19) and the hose under test, to the tested After the hose is automatically exhausted, the primary pressurization is carried out. After the pressure reaches the set value, the water supply is stopped; the air solenoid valve (4) of the air pressure control system is opened, and the air-liquid booster cylinder (5) is driven to automatically test The water pressure of the system is pressurized, and the pressurization is automatically stopped after the circuit pressure reaches the set value, and the pressure test is carried out on the tested hose, and the performance of the tested hose is judged by monitoring the internal pressure of the tested hose; the invention adopts automatic Controlled exhaust function, high efficiency, simple structure, small volume, low noise.

Description

technical field [0001] The invention relates to a hydraulic test system for braided hoses such as train brake hoses and general wind hoses, and belongs to the technical field of gas-hydraulic pressure testing. Background technique [0002] Train brake hoses and total air hoses are important accessories for the connection between vehicles, and their quality is a necessary guarantee for the safety of railway trains. Therefore, in the design and manufacture of hoses and vehicle maintenance, they need to be checked and checked. Conduct a hydrostatic strength test. The hose test is carried out on the water pressure test system. At present, most of the water pressure test systems directly use the pressure test pump to provide high-pressure water. The pressure test pump is large in size, which leads to large equipment volume, large space occupation, and is not easy to arrange; use It takes a long time for the pressure test pump to build up pressure, and the efficiency is low; ther...

Problems solved by technology

The hose test is carried out on the water pressure test system. At present, most of the water pressure test systems directly use the pressure test pump to provide high-pressure water. The pressure test pump is large in size, resulting in large equipment volume, large space occupation, and not easy to arrange; use The pressure test pump takes a long time to build up pressure, and the efficiency is low; the pressure test pump also has problems such as high noise, and the current hydraulic test system cannot automatically perform the automatic exhaust function
