Pipe Hydraulic Pressure Burst Tester , Plastic Testing Machine
Summary:
Pipe pressure burst test machine is used for long-term pressure and plastic pipe and composite pipe burst test test equipment, the product complies with ISO1167, GB / T6111 "Fluid Plastic Thermoplastic Pipe endurance test
Method ", and the applicable standards of the relevant materials. Can be applied to PVC, PE, PPR, ABS, and composite materials within the pressure detection.
Features:
- Continuous work without barriers to ensure the integrity of the test;
- The branches are independent of each other, easy to operate and maintain;
- Equipped with pressurized water tank separately, pure water is used to fill the pipe sample by the main pressure pump to ensure water quality in the pipe and improve the service life of pipeline components (such as solenoid valve and needle valve)
- The use of independent research and development, unique, pulse duty cycle pressure technology, the step-up and fill the pressure link into one, reducing a branch and the device, it reduces the risk of damage to the device;
- The use of the United States piston pump, low noise, fast pressure, short working hours, indirectly improve the life of the plunger pump;
Equipment composition Description:
The test machine by the pressure control system, pressure source, temperature medium box, fixture parts.
- The pressure control system in the control cabinet by the pressure piping and electrical control of two parts. Pressure piping from the accumulator, solenoid valve, manual needle valve, connecting pipes and other components. Electrical control by the microcontroller, LCD, pressure sensors, solenoid valves, relays, switches and other components.
- The pressure source is used to provide total pressure to the main pressure system under test conditions.
- Thermostatic medium box mainly by the box, circulating pump, heater and temperature control system. Cabinet consists of stainless steel liner, spray shell, insulation, sample holder and lid composition.
- A-type fixture, a unique design test fixture disassembly easier and more comfortable; wedge-type thread clamping device to make the clamping force greater. This series of fixtures with a reasonable structure, clamping speed, sealing and reliable, easy to remove features.
Working principle:
- Set the control pressure and range of the main pressure meter so that the pressure source will provide the pressure of 2 ~ 3MPa higher than the maximum pressure of the branch and store it in the accumulator.
- Calculate the test pressure according to the ring stress of the sample, and set the control pressure and range of the branch pressure meter accordingly. After the operation, the single-chip microcomputer controls the solenoid valve to be fully on, so that the pressure of the sample rises rapidly. Pressure reaches the set pressure into the pressure phase.
- Fill phase solenoid valve intermittent continuity based on single-chip data, the pressure source to accumulator pressure added to the sample.
- When the pressure of the pressure source drops to the lower limit of the set pressure, the column pump will stop when it starts to work up to the upper limit.
- The machine also has the functions of running, stopping, completing the test, breaking identification and the like, and enabling the operator to leave the experimental site during the experiment. When the sample appears leakage, rupture automatically shut down the road, the other tests continue normal until the test is completed. In similar models with excellent cost performance, is the ideal alternative to import products.
- The main heating tank can guarantee the life of the heating tube, extracorporeal circulation so that the water temperature in the tank uniform.
