Can dry screw vacuum pumps run for a long time?

Starting in 2021, due to the significant increase in the number of applications in the semiconductor field, dry screw vacuum pumps can be said to be properly out of the circle. Recently, we have found that some of the problems that customers often ask about dry progressive cavity pumps are very representative. Therefore, the Chinese Hokaido vacuum pump factory is unified out so that more customers and friends can understand.

Question 1: What are the requirements for lubricating oil for dry screw pumps?
The use of progressive cavity pumps is inseparable from lubricating oil, but not all lubricating oil helps it. The vacuum pump oil of the screw pump requires good smoothness, which is conducive to inhibiting corrosion and can effectively reduce adhesion wear and surface fatigue wear.
Question 2: Can the screw pump run for a long time?
In general, dry screw pumps with excellent performance can run for a long time, 24 hours if necessary.

Question 3: How to solve the problem of water intrusion of dry screw pump?
Screw vacuum pumps are electrically operated, so once water is intruded, the internal components will be damaged. When encountering such a problem, such as a large amount of water, after the discharge of oil, add new oil, and then open the gas shock valve for one hour; If the amount of water inlet is not much, such as within 2 L, pause the vacuum pump, open the drain valve, and after draining the water, open the air shock valve for one hour.

Question 4: Can a screw vacuum pump pump liquid?
The screw pump can be used in an environment with a certain amount of dust and liquid, and the vertical or horizontal screw pump should be selected according to the amount of dust and liquid.
Question 5: How to reduce the wear of the progressive cavity pump?
1. The high-speed screw pump wears more than the low-speed screw pump, because the flow and head are increased, and the power is relatively increased. At this time, the speed can be reduced by reducing the speed by reducing the reducer or the stepless speed control machine.
2. Choose a good quality screw pump, the spare parts are well-made, and the wear rate of long-term use is also low.
3. Make sure that debris does not enter the pump body.
4. Maintain a constant outlet pressure, reduce the sharp increase and decrease of pressure.
