Integrated modular assembly Hydro pressure testing machine
I. Function & Applications
Integrated modular assembly Hydro pressure testing machine is used
to do instant bursting test and long time pressure test on plastic
pipes for fluid transport, like to measure the damage time of
thermoplastic pipe under a constant pressure. This instrument is
composed of a main frame of pressure control, a constant
temperature tank and end caps. For this product is of high
precision, good looks, simple structure, good stability and
convenient operation, it becomes a necessary testing equipment for
research institutes, quality inspection departments and pipe
manufacturers.

IV. Features
A. Features of main frame
Double-tube circuit structure
Because the structure of the traditional pipe hydrostatic testing
machine is transmitted to the sample by pressure acquisition, the
other end is connected with the pressure relief valve, and There is
a pressure difference between the specimen and the sensor because
there is no reflux. In order to solve the problem, our pressure
control system are connected with the sample by double-tube.
Integrated modular assembly
Each module is 5 or 6 stations, each independent station does not
interfere with each other, can be set separately in the range of
0.2 MPa~ full load range, one test rupture does not affect the
normal test of other roads.
Complete function
With rupture identification, real-time monitoring, power-off
pressure, power-down protection, call automatic recovery. printing,
storage test results and other functions. Control the main
interface with Chinese and English selection, provide a variety of
language operation functions.
The reference horizontal plane of the pressure measuring device is
consistent with the horizontal plane of the constant temperature
medium box.
B. Features of constant-temperature tank
Constant-temperature tank is composed of the tank body, imported
circulation pump, heating unit and temperature keeping system.
1. The body is composed of structural frame, bottom, 304# stainless
steel internal bladder, and stainless steel or aluminum alloy outer
covering.
2. Thick heat insulation of rigid polyurethane foam ensures the
constant temperature and energy saving performance.
3. The cover of the constant temperature tank can be equipped with
automatic lifting and closing device, which is reliable and
convenient.
C. End caps
1.Include bolt, O ring ,vent valve etc all assembled complete.
2.Fixture structure:
Half round pot form,easy fit out , no leakage, convenient
operation.
D. Refrigeration system
Temperature range: 10~40°C
Power supply:220V single phase 2.2KW
