Key Features

  • Frame
  • Low temperature conditioning box
  • Function introduction
  • References standard

1), reasonable structure, accurate speed

The main unit is equipped with an energy storage device, which converts its elastic potential energy into dynamic energy, with an impact speed range of 1m/s to 20m/s.

2), human-computer interface, rich in information

The use of industrial-grade control terminal, large-screen color LCD touch screen, easy to operate, to provide users with more test information, such as sample low temperature state adjustment time, test run time, in-tube immediate pressure, impact speed, crack length, test temperature and other relevant information.

3), test pressure control precision, fast charging speed

High-pressure nitrogen pressure source, pressure in the range of 0 to 2.5MPa arbitrary setting, high control accuracy, easy to operate, flexible, fast pressure, large tube diameter is particularly significant, such as: DN200 to DN400 within 30s can reach the set pressure.

Plastic pipe RCP rapid crack propagation testing machine

1, ultra-low temperature, high efficiency

It can achieve -30 degrees C constant temperature, a box of multi-seat, can be with a number of different sets of tube diameter samples for low temperature conditioning;

2, high-precision temperature control system

Real-time display of the temperature in the library, automatic monitoring, control;

3, single door, pneumatic opening and closing

The box is single-positioned, built-in sample in and out of the track, easy to sample delivery. When sampling samples, the temperature fluctuates small and is reliable and safe. The box door is sealed with silicone strip and box body, and the built-in preheat device effectively avoids the phenomenon of box door seal and box freezing in ultra-low temperature state.

4, efficient refrigeration device

Refrigeration system using piston refrigeration unit, cooling using air-cooled side blowing high-efficiency condenser, 10min box can reach -30 degrees C, high refrigeration efficiency, split refrigeration cooling cooling system, cooling outdoors, does not affect indoor temperature, does not increase indoor noise.

3.1, Applicable to the maximum test tube diameter and sample length

The device can meet the test of the maximum test tube diameter of 250mm resistance to rapid crack expansion, with a total sample length of 7.5 times the sample diameter.

3.2, impact blade selection

According to the test tube diameter is different, the required impact blade and the blade positioning sample block are selected according to the pipe diameter, and the corresponding impact blade and blade positioning block are selected according to the test.

3.3, impact speed settings

According to the test method standard, the impact speed range can be selected from 5m/s to 20m/s, the test can be as needed on the touch screen directly input the required impact speed, the system automatically measures the impact edge impact speed at the moment of impact. Each test automatically measures the impact speed and automatically displays and records;

3.4, test pressure settings

The test pressure control range is 0 to 2.5MPa, the pressure sensor accuracy is 0.5%, and the maximum air source pressure is 3.0MPa.

3.5, the test process description

1) According to the test tube diameter to choose the sealing fixture and impact blade, and carry out knife operation, so that the relative position between the sealing fixture and the impact blade fixed;

2) Connect the sample with the sealing fixture for pre-treatment;

3) Set the impact speed, usually the impact speed is 15m/s;

4) After the pre-treatment of the sample is over, within 3 minutes the sample and fixture are pushed into the test host, the system automatically locks the sample, and connects the charge hose, after the two shock indicators are on, and at the same time press the impact button, the system automatically releases the impact sample, and measures the impact instant impact speed.
