Water Pressure Balance Dead Weight Tester Test Equipment, Piston 5
~ 600 bar
Description
A pressure balance is equivalent to a liquid balance. On one side,
it is the pressure generated by the weight. While the pressure in
the liquid pipe is displayed, when the two pressures are equal, the
two are balanced (the specific value of the pressure in the pipe
and the sum of the weights are detected. That is, the pressure
value in the pipeline).
When the pipeline appears micro-leakage, the balance will be
mechanically interrupted (to detect whether there is micro-leakage
in the pipeline. In order to make the balance of the pressure
balance more intuitive, we introduced the indicator system for the
first time when the pressure balance changes. The same indicator
light will be funded into different colors. This system is the
first application of Xi'an SHELOK. It has quasi-university in the
country and even in the world, making customers more convenient and
convenient.

Applications
Psiton pressure balance mainly used in oil industry, a instrument
apply to measure fluid pressure, but much accurate than pressure
gauge, used to check the pressure gauge or pressure sensor
reading.In the pipeline pressure test, the pipeline welding is
completed to conduct stress tests, stress tests primarily to
pressure capacity and the existence of micro-leakage test tube, and
the pressure balance of uncertainty and sensitivity and precision
are currently unable to replace all instruments and so the pressure
balance is one of the indispensable test piping pressure
instrument.
In the pipeline pressure test, the pipeline is welded to complete
the pressure test, the pressure test is mainly to test the pressure
capacity of the pipeline and whether there is a micro-leakage, and
the uncertainty and sensitivity of the pressure balance and high
precision are all the instruments can not be replaced , so pressure
scales are one of the indispensable instruments for pipeline
pressure testing.
Pressure balances are academically called piston pressure gauges
and are very important pressure references. Pressure balances are
isolated and improved on the basis of piston pressure gauges and
are more suitable for pipeline pressure testing.
Manual For User's
! Fill the transformer oil in the pressure balance hydraulic isolator
(open the pressure balance indicator 4)
! Connect the balance and test pressure pipe through the high
pressure hose
! Pipeline pressure, according to the indicator light to determine
when the need to add or subtract weights.
When the tube pressure is greater than the weight generated by the
weight, the green light is on, and you need to add a weight
When the tube pressure is less than the weight generated by the
weight, the red light is on, and the weight needs to be removed at
this time
When the pipeline pressure is equal to the weight generated by the
weight, the yellow light is on. At this time, the pipeline pressure
is equal to the weight generated by the weight.
!Judgment method for micro-leakage in pipelines: When the pipeline
is pressure tested, adjust the book to a balanced position, record
the number of weights and the value on each weight for a period of
time, check whether the color of the indicator light changes, and
when the color changes to red light At that time, it was proved
that there was pressure relief in the pipeline, and the small
weights were taken in order. When the balance was waited for, the
number of statistical weights was counted. The difference between
the two numbers on the front and back weights was the leakage
amount, and the pressure balance was a high-precision instrument
with a micro-leakage of 0.001. MPa can also react.
