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 ga...

When the pump chamber is in a vacuum state, due to the liquid level difference, gravity effect and pressure difference between the oil tank and the pump chamber, the oil of Roots vacuum unit will return to the pump chamber. In order to effectively solve the problem of oil return of equipment, the...

(1) Impeller cutting: due to some changes in the rated lift of the rotary vane vacuum pump in the planning and design of the pump station, it is often inconsistent with the actual lift of the water plant. Impeller cutting of the rotary vane vacuum pump is a choice method to solve the contradictio...

(1) The vacuum pump shall be installed in a solid and firm place on the ground, and sufficient space shall be reserved around it for inspection, maintenance and servicing. (2) The foundation under the base of the vacuum pump shall be kept horizontal. It is recommended to pad damping rubber at the...

The water ring vacuum pump can meet certain operating requirements in the process of use, but in the production process, it must be operated in strict accordance with the operating regulations to achieve good results. Now let’s understand the reasons for the backflow of the water ring vacuu...

What is the reason why the water ring vacuum unit cannot reach the flow rate in use? Next: 1. If the flow of the used water ring vacuum unit cannot be reached, it is likely that the impeller and pump body are worn and corroded, or the pump body is blocked and the pipeline is blocked, the elimina...

In any case, if you want to extend the service life of the equipment, you must have a correct use method. Just like the screw vacuum pump we will introduce below, the use of standard use procedures can reduce the damage to the machine and equipment caused by the wrong use method. 1. The screw va...
