150MPa high pressure hydraulic testing machine high pressure testing machine

Pressure testing machine 0-150mpa high pressure hydraulic strength testing machine pressure burst test bench

Hydraulic testing machine with a range of 0-320mpa available for selection

1、 Equipment principle

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

2、 Scope of application

Suitable for high-pressure pressure holding tests, sealing tests, burst tests, and static pressure tests of various ball valves, valves, fittings, pipelines, connectors, pressure vessels, fuel tanks, water tanks, automotive brake hoses, steering pipes, fuel pipes, air conditioning pipes, as well as hydraulic equipment, engineering machinery, mining machinery hydraulic hoses, metal pipes, non-metal pipes, joints, and accessories. It is also suitable as a testing tool for scientific research and inspection departments.

5、 Technical parameters

1. Principles of Mechanical Systems:

The entire device consists of two parts: the computer control and power source box part, and the test box and water tank part. The test parameters are set by the computer, and the pressure sensor detects the system pressure. After entering the computer through the data acquisition card, the computer captures the blasting peak value and controls the entire testing process through computer operation.

The high-pressure source adopts a gas-liquid booster pump GD400WL with a boosting ratio of 400:1; Drive pressure: 0.5-0.8MPa; The output pressure is 0-320MPa. The drive cylinder diameter of this booster pump is 160mm, and the booster cylinder diameter is 18mm. The booster pressure is infinitely adjustable, and the output pressure is!

2. Main technical parameters:

6、 Security protection

1. The equipment is equipped with an overvoltage alarm function. When the pressure in the test circuit suddenly changes, the equipment will automatically alarm. When it exceeds the safe range, the equipment will automatically shut down;

2. The equipment is equipped with a leak alarm function for pipeline and workpiece failure in the testing room;

3. Leakage protection: The equipment is equipped with a high-sensitivity leakage protection module. When the leakage protection device is activated, the circuit breaker cuts off the main circuit power supply;

4. The equipment has protection functions such as short circuit, overcurrent, phase loss, and phase sequence;

5. The equipment is equipped with an emergency stop button function: pressing the emergency stop button during operation can immediately stop the equipment.

7、 GD seriesGas liquid booster pump/pneumatic pressure testing pumpInstructions

The GD series gas-liquid booster pump adopts a single gas controlled non-equilibrium gas distribution valve to achieve automatic reciprocating motion of the pump. The gas drive part of the pump body is entirely made of aluminum alloy, and the aluminum alloy components are processed and oxidized to black to ensure the aesthetic appearance of the product. The material of the liquid receiving part is selected from carbon steel or stainless steel according to different media, and the sealing components of the pump are imported products to ensure the performance of the pump.

The diameter of the driving piston in this series is 160mm. The driving air pressure is 10 bar. To ensure the service life of the pump, it is recommended to use an air pressure of ≤ 8 bar.
