Pressure pump structure by the pump, plunger, seals, control valves and other components, mainly used in pipes, boilers, cylinders, fire equipment and other hydraulic tests and laboratories to obtain high-pressure liquid Testing equipment, then how to operate in the use of the test pump it? Here is the test pump for you to introduce the steps and introduce an example of its application. Pressure test pump operation steps and application examples First, the pressure pump operation steps The first step, test pressure pump pipe water. Install the pressure gauge, water valve and other accessories, open the exhaust valve to be tested pipeline, close the drain valve, through the nozzle into the clean water until the water is filled pipe and over a certain value of the water valve, close the exhaust valve , Stop filling. The second step, test pressure pump with oxygen connection. The oxygen bottle (bottle pressure greater than the test pressure) on the rubber band connected to the water pipe. The third step, the pressure test pump slowly boost. Slowly open the valve on the oxygen bottle, pay attention to observe the pressure gauge on the oxygen bottle, pressurized to a certain value, you should stop to check the pipeline, no problem, then continue to pressure, generally 2-3 points rose to test pressure. The fourth step, pressure test pump pressure check. For low-pressure heat pipe, pressure holding time to 5-10 minutes is appropriate in the test pressure to maintain the time, such as the pressure gauge pointer does not drop more than 0.02MPa, and no distortion of the visual pipe, that strength test pass. Final pressure test pump tightness test. The pressure dropped to the working pressure, a comprehensive inspection of the pipeline can be used 1.5g below the head hammer in the seam 1.5-20mm Department gently tapping, such as pressure gauge pointer does not drop, the pipe weld and flange connection Department did not find leakage, that can be considered tight test. Second, the application of pressure test pump Test pressure pump in Xinyi Zhongli Road thermal pipe renovation project, the method was applied, Zhong Wu Road width 42cm, heat pipe ( 219) at a height below the road surface 3.5m After wearing my arms, rise on both sides of the road. After the installation of the pipeline, using the method of hydraulic pressure test, the test pressure of 0.9MPa, after the pressure reaches the test pressure 40 minutes, pressure gauge pointer no change.
