Ⅰ. Summary:
Hydraulic pipe of PP, PE, PVC pressure testing machine is designed
and manufactured according to GB/T6111 -2003 Thermoplastics pipes
for the conveyance of fluids ----Resistance to internal
pressure----Test method and GB/T15560-1995 Standard 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. Feature:
Main Frame:
Operating terminal with touch screen or PC for test parameter
settings.
All metal components that come into contact with the medium are
made of high-quality stainless steel.
Operator-friendly display interface provides multi languages to
suit the most varied customer requirements.
Multistage protections are from electric partt, mechanical part as
well as software.
Reliable data exchange via TCP/IP protocol.
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 is a constant-temperature tank working with the hydrostatic
pressure testing machine.
Control the temperature, and also can be used for other aspects.
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.
Main frame PC control unit:
It adopts MODBUS communication protacol to the computer, which the
mainstream industrial control communication protocol to ensure high
reliability of data transmission and other general-purpose
inteligent instrumentation compatibility.
