Dry screw vacuum pump is a relatively common type of vacuum pump products, with a wide variety of categories and a relatively large application span. In our normal use of dry screw vacuum pump, it is inevitable that various problems will occur. For example, the dry screw vacuum pump is lack of gas, so what is the reason for the lack of gas volume of dry screw vacuum pump? The dry screw vacuum pump is summarized in the following four aspects through technical analysis and experience.
Gas and liquid leakage of pipeline
The pipeline of the dry-type screw vacuum pump leaks gas and liquid, and the adverse consumption becomes larger; The weak power supply of the motor leads to its insufficient speed; Less water supply; There is too large gap between impeller and distribution plate; The lower mechanical sealing makes the pipeline leak gas and liquid; Circulating water is difficult to clean. In case of such problems, it is required to check in time, check the tightness of check valves, pipelines and machinery, etc., and eliminate them one by one.
Whether the model selection is suitable
The reason for the lack of air volume of dry-type screw vacuum pump may also be that the model selection is not the required specification, and the model selection is wrong. Due to the high air volume required at the equipment application site and the low air volume of the pump can not meet the required specifications, when we select the dry screw vacuum pump, we should control the parameters we need, and then compare the parameters of the target product, and stop the selection of effective vacuum pump.
Whether the power supply is normal
The dry-type screw vacuum pump of the recent device has a lack of air. First, we should check whether the power connection of the dry-type screw vacuum pump is normal, and whether it is the rotation of the dry-type screw vacuum pump caused by the reverse connection of the line, which finally causes the dry-type screw vacuum pump to have a lack of air. If this kind of problem is encountered, it needs to be carefully checked.
Excessive wear of impeller
For the dry screw vacuum pump that has been used for a long time, the reason for the lack of air volume is likely to be caused by the excessive wear of the impeller or pump body. Of course, it may also be caused by the blockage of the dry screw vacuum pump body or pipe blockage. To solve such problems, first check whether the dry screw vacuum pump body and pipe are blocked, and then check the wear of the impeller and pump body, If problems are found, it is necessary to replace new parts or buy dry screw vacuum pump products of corrosion-resistant materials in time.
The above is the reason for the lack of air volume of dry screw vacuum pump. It is only for your reference. For more information, please pay attention to our website.
