Dry screw vacuum pump: a powerful assistant in the electronics industry
Dry screw vacuum pumps have a wide range of applications in fields such as electronics, semiconductors, chemical engineering, and medicine. Especially in the semiconductor field, it is used for producing chips and manufacturing liquid crystal displays. This vacuum pump utilizes a pair of screws to synchronously rotate in reverse within the pump casing, producing exhaust and suction effects. Let’s take a detailed look at the performance and selection criteria of dry screw vacuum pumps.
Dry screw vacuum pump of performance
Short gas path design: avoids gas condensation and corrosion.
Nickel plating/PTFE coating: These coatings are used on the contact surface to prevent gas corrosion of the components.
Water jacket cooling system: The rotor adopts a water jacket cooling system to effectively control the gas temperature.
Metal free contact: reduces vibration and wear, achieving a low-noise effect.
Ultimate pressure: Under low vacuum and high flow conditions, the vacuum ultimate pressure can reach 0.01 Torr, ensuring sustainable operation of the equipment and improving work efficiency.
How to choose a dry screw vacuum pump?
Pressure range: Ensure that the vacuum pump operates within a reasonable pressure range.
Ultimate pressure: The ultimate pressure of a dry screw vacuum pump is usually one level lower than the process requirements.
Front stage pump combination: Some vacuum pumps cannot operate normally at atmospheric pressure and require a front stage pump combination to eliminate the amount of gas generated during operation.
Gas composition: Understand the gas composition and choose the appropriate pump. When there is steam, particles, or corrosive gases, auxiliary equipment such as dust collectors can be installed.
Shock absorption measures: Dry screw vacuum pumps generate vibration during operation. If this affects the process, a vibration free pump or shock absorption measures can be chosen.
Oil pollution requirements: Select the appropriate pump type based on the requirements of the vacuum system for oil pollution. For example, when there is no oil, low-temperature pumps, water ring pumps, etc. can be selected, and measures to prevent oil pollution can be taken when necessary.
Through the above introduction, I believe you have gained a deeper understanding of dry screw vacuum pumps. This type of vacuum pump plays an important role in the electronics industry, and selecting the appropriate pump can greatly improve work efficiency.
