Hydrostatic pressure testing equipment for Plastic(Composite)
Pipes, Fittings, Manholes, Valves)
Ⅰ. Application:
The Hydrostatic pressure testing equipment is used for the
resistance to intermal pressure determination of the plastics
pipes, fittings and valves, which are given the same or different
pressure with the constant temperature.
It is mecessary for the producers, scientific research agency and
qualith-control institution to check and measure the performance of
the test piece.
Ⅱ. 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.
