GWSP Oil free Scroll Vacuum Pump
Working principle:
GWSP oil free scroll vacuum pump is constructed with pump head assembly, crank pin assembly, bracket assembly, air flush assembly,and exhaust valve assembly.Two spiral cylinders, 1 offset and orbiting against the other fixed with an offset of 180° to form several crescent-shaped pockets of different sizes. By means of an eccentric drive, the orbiting scroll is made to orbit about the fixed scroll, reducing the volume of the pockets and compressing gas from outside towards the inside thereby pumping the gas from vacuum chamber.

How do scroll vacuum pumps compare to other types of vacuum pumps in terms of performance?
Scroll vacuum pumps offer unique advantages and perform differently compared to other types of vacuum pumps. Here's a detailed comparison of scroll vacuum pumps with other common vacuum pump types:
1. Scroll Vacuum Pumps vs. Rotary Vane Pumps:
a. Oil Contamination: Scroll vacuum pumps operate without oil lubrication, eliminating the risk of oil contamination in the pumped gases or the surrounding environment. In contrast, rotary vane pumps require oil lubrication, which can introduce oil vapor or particles into the vacuum system.
b. Vibration and Noise: Scroll vacuum pumps operate with low vibration levels and produce less noise compared to rotary vane pumps. Rotary vane pumps can generate higher levels of vibration and noise due to the reciprocating motion of the vanes.
c. Ultimate Vacuum: Rotary vane pumps can achieve lower ultimate vacuum levels compared to scroll vacuum pumps. They are capable of reaching vacuum levels in the range of 10-3 to 10-4 millibar (mbar), while scroll vacuum pumps typically achieve vacuum levels in the range of 10-2 to 10-3 mbar.
2. Scroll Vacuum Pumps vs. Turbomolecular Pumps:
a. Pumping Speed: Turbomolecular pumps offer higher pumping speeds compared to scroll vacuum pumps. Turbomolecular pumps can achieve faster evacuation rates, making them suitable for applications that require rapid pumpdown or high gas flow rates.
b. Ultimate Vacuum: Turbomolecular pumps can achieve much lower ultimate vacuum levels compared to scroll vacuum pumps. They are capable of reaching vacuum levels in the range of 10-7 to 10-10 mbar, making them suitable for ultra-high vacuum (UHV) applications.
c. Complexity and Cost: Turbomolecular pumps are more complex and expensive compared to scroll vacuum pumps. They often require additional supporting equipment, such as backing pumps or foreline traps, which can increase the overall system complexity and cost.
3. Scroll Vacuum Pumps vs. Diaphragm Pumps:
a. Contamination Resistance: Scroll vacuum pumps offer better contamination resistance compared to diaphragm pumps. Diaphragm pumps can be prone to contamination when handling corrosive or particulate-laden gases.
b. Ultimate Vacuum: Scroll vacuum pumps can achieve lower ultimate vacuum levels compared to diaphragm pumps. Diaphragm pumps typically reach vacuum levels in the range of 10-2 to 10-3 mbar, similar to scroll pumps, but may have limitations in achieving deeper vacuum levels.
c. Durability: Scroll vacuum pumps are generally more durable and require less maintenance compared to diaphragm pumps. Diaphragm pumps utilize flexible membranes that can wear out over time and may require periodic replacement.
In summary, scroll vacuum pumps offer advantages such as oil-free operation, low vibration and noise levels, and contamination resistance. However, their ultimate vacuum levels may not match those of turbomolecular pumps or rotary vane pumps. The choice of vacuum pump depends on specific application requirements, including the desired vacuum level, pumping speed, contamination sensitivity, and budget constraints.
What are the primary advantages of using scroll vacuum pumps?
Scroll vacuum pumps offer several advantages that make them a preferred choice in various applications. Here's a detailed explanation of the primary advantages of using scroll vacuum pumps:
1. Oil-Free Operation:
One of the significant advantages of scroll vacuum pumps is their oil-free operation. Unlike some other types of vacuum pumps, scroll pumps do not require oil for lubrication or sealing purposes. The interlocking scrolls create a sealing mechanism without the need for any lubricating medium. This eliminates the risk of oil contamination in sensitive applications, such as semiconductor manufacturing or laboratory environments, where oil-free conditions are crucial. It also reduces maintenance requirements, as there is no need for oil changes or monitoring oil levels.
2. High Efficiency:
Scroll vacuum pumps are known for their high efficiency. The continuous spiral motion of the scrolls ensures smooth operation and minimizes energy losses. The absence of frictional parts, such as piston rings or vanes, reduces internal losses and improves overall efficiency. Scroll pumps can achieve high pumping speeds and are capable of reaching deep vacuum levels. Their efficiency makes them suitable for applications where fast evacuation or high vacuum levels are required, such as in analytical instruments or in the production of electronic components.
3. Low Noise and Vibration:
Scroll vacuum pumps operate quietly and generate minimal vibrations. The spiral motion of the scrolls results in a smooth and continuous operation, reducing noise levels compared to other types of pumps. The absence of reciprocating parts, such as pistons or vanes, further contributes to the low noise and vibration levels. This characteristic is particularly advantageous in applications where noise reduction and minimal vibration are essential, such as in medical environments, laboratories, or research facilities.
4. Compact Size:
Scroll vacuum pumps are compact in size, making them suitable for applications where space is limited. Their small footprint allows for easy integration into existing systems or equipment. The compact size is especially beneficial in portable or handheld devices, where size and weight considerations are crucial. The compact design of scroll pumps also simplifies installation and maintenance, as they require less space and can be easily maneuvered or relocated as needed.
5. Minimal Maintenance:
Scroll vacuum pumps require minimal maintenance compared to some other vacuum pump types. The absence of oil eliminates the need for oil changes or monitoring oil levels. Scroll pumps typically have a simple design with fewer moving parts, reducing the risk of mechanical failure and the need for frequent repairs. This results in lower maintenance costs and less downtime, contributing to increased productivity and efficiency in various applications.
6. Clean and Contamination-Free:
Scroll vacuum pumps offer clean and contamination-free operation. The absence of oil means there is no risk of oil contamination in the evacuated environment, making them suitable for applications where maintaining a clean and pure atmosphere is critical. This is particularly important in industries such as semiconductor manufacturing, pharmaceuticals, or food processing, where even the slightest contamination can have significant consequences. The clean operation of scroll pumps ensures the integrity and quality of the final products.
7. Reliable Performance:
Scroll vacuum pumps are known for their reliable performance. The simplicity of their design, with fewer moving parts, reduces the risk of mechanical failure and improves overall reliability. Scroll pumps can operate continuously for extended periods without significant performance degradation. Their reliable performance makes them suitable for critical applications where consistent and dependable vacuum generation is essential.
In summary, the primary advantages of using scroll vacuum pumps include oil-free operation, high efficiency, low noise and vibration levels, compact size, minimal maintenance requirements, clean and contamination-free operation, and reliable performance. These advantages make scroll vacuum pumps a preferred choice in various industries and applications, ranging from semiconductor manufacturing and laboratories to medical equipment and research facilities.
