The difference between screw vacuum pump and roots vacuum pump

At present, there are many types of vacuum pumps, widely used, according to the industry and the use of different environments, different series and specifications of vacuum pumps will also be different. The following is mainly distinguished from three points: performance characteristics, application range, and working principle:

1. Different performance characteristics:

Screw vacuum pump: compact and simple structure, no need for any working medium, no oil pollution, no sewage discharge, energy saving and emission reduction effect is remarkable.

Roots vacuum pump is characterized by: fast start-up, low power consumption, low operation and maintenance costs, large pumping speed, high efficiency, and insensitivity to a small amount of water vapor and dust contained in the pumped gas.

2. Different application ranges:

Roots vacuum pumps are mainly used in coal mines (gas pumping), mining, papermaking, chemical industry, pharmaceutical, beer, food, building materials, metallurgy, plastics, electrical appliances and other industries.

3. Different working principles

Screw vacuum pumps use a pair of screws to synchronize high-speed reverse rotation in the pump casing to produce suction and exhaust.

Roots vacuum pump pump is equipped with two vane-shaped rotors rotating synchronously in opposite directions, and there is a small gap between the rotor, the rotor and the inner wall of the pump casing without contact with each other.

Therefore, when choosing pump products such as vacuum pumps, you must first understand your own needs, as well as the application range, performance characteristics and so on of vacuum pumps of different specifications and models.

According to the different production requirements of customers, our company will configure the most suitable pump for your machine.
