[0002] When testing the pressure resistance of municipal pipeline systems, a pipeline pressure tester is often used. This equipment is usually used to ensure that the pipeline system can withstand the pressure under normal operating conditions and will not leak or have other problems. Therefore, in order to ensure the safety performance of the water supply pipeline so that it can meet the needs of normal use and emergencies, it is necessary to conduct a pressure test on the water supply pipeline.

[0003] At present, the test method used in the water supply pipeline pressure test in the industry is: connect the water pump to the water pipe, turn on the motor, and when the pressure gauge shows a specified value, manually turn off the motor. When the pressure gauge shows that the pressure is insufficient, manually turn on the motor to keep the pressure at the test pressure for a period of time. The existing test method has the following shortcomings during use: First, the existing test method requires the test personnel to stay at the test site to observe the pressure gauge value, the degree of automation is low, and the labor intensity of the test personnel is high; in addition, the pressure in the existing test method cannot be replenished in time, and the error of the test result is large.
