China Hot selling Ruvac Sogevac Roots Rotary Vane Vacuum Pump Equipment Ws Wsu Wa Wau251 vacuum pump connector

Beschreibung des Produkts

The series WA/WAU Roots vacuum pumps are provided with directly flange-mounted air-cooled standard three-phase motors. The oiled radial sealing rings of the RUVAC WA/WAU for sealing the shaft against the atmosphere are made of FPM (FKM) (fluorpolymer).
Roots vacuum pumps of the series WAU/WSU/WHU are provided with an additional integrated pressure equalization line and a differential pressure valve.
Pumps from these series are supplied with a vertical pumping action as standard.

Design Principle

Roots vacuum pumps, which are also called Roots blowers, are rotary plunger-type pumps where 2 symmetrically shaped impellors rotate in opposite directions inside the pump housing.
The figure-of-8 rotors are synchronized by a gear which ensures that the impellors are counter-rotating in such a way, that they are near to 1 another and to the housing without actual contacting.
In rotor positions I and II (see figure on the left) the volume of the intake is increased. As the rotors turn further to position III a part of the volume is cut off from the intake side.
In position IV this volume is opened to the exhaust side and gas under fore vacuum pressure (higher than the intake pressure) flows in. This gas compresses the gas coming from the intake. As the rotors turn further the compressed gas is ejected through the exhaust flange.
This process repeats itself twice for each rotor per full turn.
As the rotors do not come into contact with the pump’s housing Roots vacuum pumps may be operated at high speeds. Thus a high pumping speed is obtained from comparably small pumps.

Considerations for Selecting a Vacuum Pump for Cleanroom Applications

When it comes to selecting a vacuum pump for cleanroom applications, several considerations should be taken into account. Here’s a detailed explanation:

Cleanrooms are controlled environments used in industries such as semiconductor manufacturing, pharmaceuticals, biotechnology, and microelectronics. These environments require strict adherence to cleanliness and particle control standards to prevent contamination of sensitive processes or products. Selecting the right vacuum pump for cleanroom applications is crucial to maintain the required level of cleanliness and minimize the introduction of contaminants. Here are some key considerations:

1. Cleanliness: The cleanliness of the vacuum pump is of utmost importance in cleanroom applications. The pump should be designed and constructed to minimize the generation and release of particles, oil vapors, or other contaminants into the cleanroom environment. Oil-free or dry vacuum pumps are commonly preferred in cleanroom applications as they eliminate the risk of oil contamination. Additionally, pumps with smooth surfaces and minimal crevices are easier to clean and maintain, reducing the potential for particle buildup.

2. Outgassing: Outgassing refers to the release of gases or vapors from the surfaces of materials, including the vacuum pump itself. In cleanroom applications, it is crucial to select a vacuum pump with low outgassing characteristics to prevent the introduction of contaminants into the environment. Vacuum pumps specifically designed for cleanroom use often undergo special treatments or use materials with low outgassing properties to minimize this effect.

3. Particle Generation: Vacuum pumps can generate particles due to the friction and wear of moving parts, such as rotors or vanes. These particles can become a source of contamination in cleanrooms. When selecting a vacuum pump for cleanroom applications, it is essential to consider the pump’s particle generation level and choose pumps that have been designed and tested to minimize particle emissions. Pumps with features like self-lubricating materials or advanced sealing mechanisms can help reduce particle generation.

4. Filtration and Exhaust Systems: The filtration and exhaust systems associated with the vacuum pump are critical for maintaining cleanroom standards. The vacuum pump should be equipped with efficient filters that can capture and remove any particles or contaminants generated during operation. High-quality filters, such as HEPA (High-Efficiency Particulate Air) filters, can effectively trap even the smallest particles. The exhaust system should be properly designed to ensure that filtered air is released outside the cleanroom or passes through additional filtration before being reintroduced into the environment.

5. Noise and Vibrations: Noise and vibrations generated by vacuum pumps can have an impact on cleanroom operations. Excessive noise can affect the working environment and compromise communication, while vibrations can potentially disrupt sensitive processes or equipment. It is advisable to choose vacuum pumps specifically designed for quiet operation and that incorporate measures to minimize vibrations. Pumps with noise-dampening features and vibration isolation systems can help maintain a quiet and stable cleanroom environment.

6. Compliance with Standards: Cleanroom applications often have specific industry standards or regulations that must be followed. When selecting a vacuum pump, it is important to ensure that it complies with relevant cleanroom standards and requirements. Considerations may include ISO cleanliness standards, cleanroom classification levels, and industry-specific guidelines for particle count, outgassing levels, or allowable noise levels. Manufacturers that provide documentation and certifications related to cleanroom suitability can help demonstrate compliance.

7. Maintenance and Serviceability: Proper maintenance and regular servicing of vacuum pumps are essential for their reliable and efficient operation. When choosing a vacuum pump for cleanroom applications, consider factors such as ease of maintenance, availability of spare parts, and access to service and support from the manufacturer. Pumps with user-friendly maintenance features, clear service instructions, and a responsive customer support network can help minimize downtime and ensure continued cleanroom performance.

In summary, selecting a vacuum pump for cleanroom applications requires careful consideration of factors such as cleanliness, outgassing characteristics, particle generation, filtration and exhaust systems, noise and vibrations, compliance with standards, and maintenance requirements. By choosing vacuum pumps designed specifically for cleanroom use and considering these key factors, cleanroom operators can maintain the required level of cleanliness and minimize the risk of contamination in their critical processes and products.
