1、 Equipment principle

The test bench uses compressed air as the power source, and the output liquid pressure is proportional to the driving air source pressure. By adjusting the pressure of the driving air source, the corresponding hydraulic pressure can be obtained. According to the different pressures of the test piece, input the experimental data, and the computer automatically adjusts the driving gas pressure. The high-pressure pump generates high-pressure liquid, which is transmitted to the test piece through the high-pressure pipeline through the pressure control system for static pressure test and burst test

2、 Scope of application

It is applicable to the high-pressure pressure and pressure maintaining test, sealing test, pressure blasting and static pressure test of pressure equipment, pipelines and components such as various ball valves, valves, pipe fittings, pipes, connectors, pressure vessels, oil tanks, water tanks, automobile brake hoses, steering pipes, fuel pipes, air conditioning pipes, hydraulic hoses of hydraulic equipment, engineering machinery and mining machinery, various metal pipes, non-metal pipes, joints and accessories. At the same time, it is also suitable for scientific research and inspection departments as testing tools.

3、 Model meaning

BPT-GD400-MPA

Description: BPT ---- hydraulic blasting test bench

Gd400 --- boost ratio: 400:1 (different booster pumps are selected under different working conditions and different pressure ranges)

MPA ------- computer control (control mode can be selected as required)

4、 Equipment function

Working pressure: 0-320

Pressure: 320MPa (optional)

Test ambient temperature and medium temperature: normal temperature;

The test pressure is stepless adjusted and controlled by computer program. After the test parameters are set, it can automatically fill water, boost pressure, maintain pressure (blasting) and relieve pressure

The test procedures include:

① Constant speed boosting blasting

② . constant speed boosting - pressure maintaining - pressure relief

③ . constant speed boosting - pressure maintaining - blasting - pressure relief

Realize the computer control function. During the pressure test, you can set a single-stage or multi-stage pressure holding test arbitrarily, or you can burst directly after pressure holding or leakage measurement. The pressure rise speed can be kept constant, stepless adjustment can be realized, and the pressure rise speed can be displayed; When the test piece breaks and the blasting equipment stops pressurizing automatically, the test data and curve parameters can be displayed in real time, the test results can be saved automatically, and the test report can be queried and printed arbitrarily; The printed contents include experimental items, boosting speed, pressure time curve, test time, manufacturer, model, test number and inspector.
