Ⅰ. Application:
The machine is designed and manufactured according to GB/T6111 Thermoplastics pipes for the conveyance of fluids ----Resistance to internal pressure----Test method and GB/T15560Standard test method for short-time hydraulic failure and resistance to constant internal pressure of the plastics pipes for the transport of fluids . It is suitable to determine the pressure-resisting broken time or the maximum pressure value of instantaneous blast of thermoplastic pipes and compound pipes (such as PP-R ,PP-B ,PP-A ,PE ,PE-X ,PVC ,PVC-U and PVC-C ) under long-term constant internal pressure and temperature .It is indispensable for manufacturers of plastic pipes and testing institutions .
Ⅱ. Standards:
ISO1167-2006, ASTMD1598-2004, ASTMD1599, ISO9080, CJ/T108, ASTMF1335.
Ⅲ. Feature:
Main Frame:
It consists of pressure micro control parts, automatic filling pressure and electric discharge pressure parts, pressure micro control part adopts the microcomputer MCU control; equipped with high resolution, high speed of ∑ - delta 16-bit adc chip, real-time communication and computer; and it can automatically fill and relief pressure according to the situation of pressure.
Pressure Station:
Its main function is to provide pressure to the main frame, the requirement of lower limit pressure of pressure station requirement must be higher than all tested specimen. The plunger pump of the station is made in the United States (large flow, low noise, high pressure, free maintenance).
Water Tank:
It consists of electric opening part, self-circulation part, heating part, automatic water filling part and insulation part.
Temperature Control System:
Accurately control the temperature of the water tank, temperature display, set temperature individually. It can control the liquid level of tank at a reasonable position, at the same time it can also guarantee the temperature.
Software System:
By connecting with RS232 serial interface to the pressure on the host, it can provide the parameters setting, calibration, pressure relief, zero, amplitude modulation, drawing the test, test records and print test reports and other functions.
