root pump vacuum

Root vacuum pump working principle

• The working principle of the Root vacuum pump is to use a pair of blade-shaped rotors to synchronously and counter-rotate in the pump chamber, sucking the gas from the air inlet, compressing it and expelling it through the exhaust port to achieve the air extraction function. ‌
• The characteristic of this kind of pump is that there is a certain gap between the rotors and between the rotors and the inner wall of the pump casing, allowing high-speed operation.
• Roots vacuum pump is a kind of vacuum pump without internal compression. Usually the compression ratio is very low, so it needs to be used in conjunction with a backing pump to achieve efficient pumping.
• This kind of pump is widely used in the fields of petroleum, chemical industry, plastics, pesticides, steam turbine rotor dynamic balancing, aerospace space simulation and other fields. It is favored because of its fast start-up, low power consumption, low operation and maintenance costs and other characteristics. favor. ‌

What is the difference between Roots blower and vacuum pump?

• 1.Working principle
• Roots blower is a device that achieves gas flow through two intermeshing rotors. It mainly sucks gas from one air inlet through the rotating rotor, and then discharges it through the other air outlet. The vacuum pump removes gas by using some method to reduce the air pressure inside the closed container. There is a big difference in how the two work.
• 2.Use
• Roots blowers are generally used to pressurize and transport gas, increase gas density, increase gas flow rate, etc. Mainly used in various industrial fields, such as food processing, electronic equipment, chemical industry, etc. The vacuum pump is mainly used to remove the gas inside the container to create a vacuum environment. Common uses include manufacturing semiconductors, vacuum heat treatment, vacuum cooling, vacuum packaging, etc.
• 3.Performance
• Roots blowers excel in pumping speed, volumetric efficiency and differential pressure range, and are capable of continuous operation for long periods of time, delivering clean, oil-free gas, making them ideal for many industrial industries. The performance of vacuum pumps may vary depending on their design use and operating conditions.

What is the pressure of a Roots pump?

• The working pressure range of a Roots pump is usually between 0.1 and 1.0 MPa, but the specific working pressure range is determined based on the specific pump type, material, rotation speed and other factors. Some special Roots pumps, such as high vacuum Roots pumps and deep well pumps, etc., have different working pressure ranges.
