Common Question Answers of Conventional Dry Screw Vacuum Pump

1. How to Select a Model of the Conventional Dry Screw Vacuum Pump to Meet High - Performance Applications?

When selecting a model, factors such as pumping rate, ultimate full pressure, special requirements of the application scenario, and budget need to be comprehensively considered. For example, semiconductor manufacturing has high requirements for vacuum degree and cleanliness, so models with low ultimate full pressure and oil - free flow - through can be selected; if large - scale chemical production requires rapid gas extraction, specifications with high pumping rates should be emphasized.

2. What to Do if the Vacuum Degree of the Dry Screw Vacuum Pump is Insufficient during Operation?

First, check whether there is leakage in the intake pipeline, which can be detected by methods such as applying soapy water; secondly, check whether the seals inside the vacuum pump are worn, and if so, replace them in a timely manner; in addition, check whether the motor speed is normal, as a decrease in motor speed caused by motor failure will also affect the vacuum degree.

3. What are the Key Points of the Maintenance of the Conventional Dry Screw Vacuum Pump?

Regularly check the quantity and quality of lubricating oil and replace the grease according to the specified time; check whether the cooling water pipeline is unobstructed and whether there is any water leakage; regularly clean the filter to prevent impurities from entering the pump body; check whether the connection parts of the equipment are loose to ensure the stable operation of the equipment.

4. How to Realize the Remote Control Function of the Dry Screw Vacuum Pump?

By installing an intelligent control system, connect the vacuum pump to the remote control terminal and use network technology to achieve data transmission. Operators can monitor the operating parameters of the equipment in real - time through terminals such as computers or mobile phones and perform operations such as starting, stopping, and adjusting the speed.

5. How to Ensure Compliance with Pharmaceutical Production Specifications when the Conventional Dry Screw Vacuum Pump is Applied in the Pharmaceutical Industry?

Its oil - free and pollution - free characteristics themselves meet the cleanliness requirements of pharmaceutical production. In addition, the materials and surface treatment of the equipment should meet the standards of the pharmaceutical industry, and the equipment should be regularly cleaned and disinfected to ensure that it does not affect the quality of drugs.

6. What are the Requirements for the Foundation during the Installation of the Dry Screw Vacuum Pump?

The foundation should have sufficient strength and stability to withstand the vibration and weight generated during the operation of the equipment. The flatness error of the foundation should be controlled within the specified range to ensure the levelness of the equipment installation and avoid operating failures caused by equipment tilting.

7. What Factors will Affect the Pumping Rate of the Conventional Dry Screw Vacuum Pump?

Motor speed, gas temperature, gas composition, and pipeline resistance will all affect the pumping rate. When the motor speed decreases, the pumping rate will follow suit; if the gas temperature is too high, the gas volume will expand, reducing the pumping efficiency; if the gas contains impurities or viscous substances, it may block the internal channels of the pump body; excessive pipeline resistance will hinder gas flow and also reduce the pumping rate.

8. In What Aspects are the Advantages of the Dry Screw Vacuum Pump Reflected Compared with Other Types of Vacuum Pumps?

Compared with water - ring pumps and reciprocating pumps, the dry screw vacuum pump has a higher vacuum degree, is oil - free and pollution - free, and can meet higher - requirement processes; compared with other dry vacuum pumps, it has complete specifications, a wider application range, high - efficiency and stability, easy maintenance, and lower operating costs.

9. In Which Specific Links is the Conventional Dry Screw Vacuum Pump Mainly Applied in the Photovoltaic Industry?

It is mainly applied in the silicon wafer crystal pulling process to maintain the vacuum state in a high - temperature environment and ensure the growth quality of silicon wafers; in the battery module packaging link, rapid gas extraction realizes vacuum packaging, improving the stability and service life of battery modules.

10. What is the Relationship between the Price and Performance of the Dry Screw Vacuum Pump?

Although the initial purchase price may be relatively high, considering factors such as the improvement in production efficiency, reduction in maintenance costs, and long service life brought about by its high performance, in the long run, it has a higher cost - performance ratio and can save the overall operating costs for enterprises.
