Roots blower manufacturer

Roots blower, also known as roots blower. The utility model belongs to a volumetric rotary blower, which uses two or three blade rotors to make relative motion in the cylinder to compress and transport gas. The blower is simple in structure and convenient in manufacture. It is suitable for gas conveying and pressurizing in low pressure situations and can also be used as a vacuum pump.

Roots blower working principle:

Roots blower is a volume rotary blower. The compressor keeps the two rotors in mesh by synchronous gears at the rotor shaft ends. Each concave curved surface part of the rotor and the inner wall of the cylinder constitute the working volume, which takes gas from the suction port during the rotor rotation. When the rotor moves to the near exhaust port and communicates with the exhaust port, the pressure in the working volume rises suddenly because of the high pressure gas reflux, and then the gas is transported to the exhaust channel. . The two rotors are not in contact with each other, and they are sealed by a tightly controlled clearance, so the exhausted gas is not contaminated by lubricating oil.

Roots blower features:

1, because the impeller in the body circulation without friction, no need to smooth, so that the exhaust gas does not contain oil. It is an ideal source of energy for industrial manufacturing such as chemical industry and food industry.


2. Roots blower belongs to capacity transfer blower. When applied, as the pressure changes and changes, the scalar transformation is very small. But scalar changes and changes with speed. Therefore, the selection field of pressure is very wide, and the selection of scalar can be achieved and realized by selecting the rotational speed.


Roots blower transport medium for clean air, clean gas, sulfur dioxide and other inert gases, special gas industries (gas, natural gas, methane, carbon dioxide, sulfur dioxide, etc.) and high-pressure working conditions of the preferred products. In view of the above characteristics, it can be widely used in metallurgy, chemical industry, fertilizer, petrochemical, instrumentation, building materials industry.

Manufacturer of roots blower:

Shanghai EVP devotes itself to the research and development and application of mechanical equipment, and provides you with higher quality root blower -- professional sewage treatment, breeding and aeration equipment, and superior gas transmission equipment.
