Hydrostatic pressure testing machine for long term test 1000 hr and
short term test of 1 hr
Ⅰ. Overview:
Hydrostatic pressure testing machine for long term test 1000 hr and
short term test of 1 hr is suitable for the determination of damage
resistance time of thermoplastic pipeline under instantaneous
hydraulic blasting and long-term constant pressure. It is an
indispensable testing instrument for scientific research institute,
quality inspection department and pipe material production
enterprises. The water pressure testing machine adopts computer
embedded control. Modular design with independent control. If any
problem occurs, as long as the cut-off valve at the current station
is closed, it will not affect the normal operation of other
stations. It has the functions of pipe fracture recognition,
real-time monitoring, call data recovery, printing, test result
storage, sample pretreatment setting and so on. Such a feature, and
according to the needs of national holidays, can store up to 7 days
of data. This machine is widely used in the internal pressure test
of various plastic tubes, which is an ideal testing equipment for
building materials industry, pipe manufacturing factory, national
inspection department and scientific research department..
Ⅱ. System Feature:
1. Industrial tablet control, direct control.
2. The machine is combined with the "precision pressure control
unit" multi-channel.
3. It is controlled both by PC and “Precision Pressure Controlling
Unit”.
4. Every station controls separately. The most station can reach
100.
5. It can do hydrostatic test, burst test, 8760 test and so on.
6. The pressure can be from 3 to 100MPa.
7. It can distinguish eight testing condition including pressure
up, pressure down, pressure compensation, pressure exceeding,
running, ending, leakage, and exploding. And also it can judge both
effective and ineffective time parameters automatically. (The
effective time means the time of the pressure within the setting
pressure.)
