Applications of pressure balance water pressure testing equipment dead weight tester:

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 of pressure balance water pressure testing equipment dead weight tester:

1. Fill the transformer oil in the pressure balance hydraulic isolator (open the pressure balance indicator 4)
2. Connect the balance and test pressure pipe through the high pressure hose
3. 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.
4. 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.
