Hydrostatic Pressure Testing Machine Designed for Constant
Temperature Pressure Testing of Plastic Pipes Fittings and Valves
Application:
The Hydrostatic Pressure Testing Equipment is engineered for
determining the internal pressure resistance of plastic pipes, pipe
fittings and valves, which are subjected to identical or variable
pressure under constant temperature conditions.
It acts as an indispensable testing device for manufacturers,
scientific research institutions and quality control authorities to
conduct performance inspection and measurement on test specimens.
Feature:
This equipment is composed of precision pressure control
components, automatic pressure charging and discharging modules,
with the precision pressure control section utilizing MCU
microcomputer-based regulation. It is fitted with a
high-resolution, high-speed ∑-delta 16-bit ADC chip that enables
real-time data communication with the host computer, and it can
implement adaptive automatic pressure charging and relief in
accordance with real-time pressure conditions.
Pressure Station:
Its core function is to supply stable pressure to the main testing
unit, with the minimum pressure threshold of the pressure station
required to be higher than the pressure demand of all tested
specimens. The plunger pump of the pressure station is imported
from the United States, featuring large flow rate, low noise, high
pressure resistance and maintenance-free operation.
Water Tank:
The water tank is constructed with electric opening mechanisms,
self-circulation modules, heating units, automatic water
replenishment systems and thermal insulation components,
integrating all functional sections for liquid circulation and
temperature preservation.
Temperature Control System:
This system precisely regulates the water temperature inside the
tank, with independent functional modules for real-time temperature
display and separate temperature setpoint adjustment. It can stably
maintain the tank’s liquid level at an optimal operating position
while ensuring the consistency of the test temperature throughout
the entire testing process.
Software System:
Connected to the main pressure testing unit via an RS232 serial
interface, the software system supports a comprehensive range of
operational functions including test parameter configuration,
equipment calibration, pressure relief, zero calibration, amplitude
adjustment, real-time test curve plotting, full-process test data
logging and standardized test report printing.
