With the use rate of screw vacuum pump is more and more common, its quality is also getting better and better, in order to make better use of it, let's understand the detection methods of screw vacuum pump.


First of all, we need to know how much pressure the screw vacuum pump can withstand, in order to have a good degree of control in the subsequent filling stage of air injection leak detection method. After understanding the characteristics of its own variable frequency screw vacuum pump, first of all, we must ensure that the screw vacuum pump is clean, we must carefully clean the vacuum pump, including some oil and dust particles. The light for leak detection should be better, the background in the sink should be dark, the water should be clear, and there should be no vapor mist on the water.


Screw vacuum pump must be inflated first, and then put into the water, otherwise if there is a big leak, the water can enter the container, and the hole can be blocked by water. Before putting into water, first use the listening method to check whether there is a big leak, and then put into water after cleaning the big leak, otherwise it will affect the detection of small leak. Screw vacuum pump in the water to put stable, wait for the surface to calm down after the line of inquiry. The inspected part of the vacuum pump should be as close to the water surface as possible.

When there is a big leak, it should be repaired before continuing to check the small leak. When the tested part of the screw vacuum pump is just put into the water, bubbles can appear on the surface of the tested part. If the bubbles no longer appear after they are erased or pierced, it can be judged that there is no leakage at the place where the original bubbles are generated. If the bubbles are regularly presented one after another, there must be a leak in the place where the bubbles are produced.
