The blower is eccentric to the rotor biased in the cylinder and causes the volume change between the blades in the rotor slot to suck, compress and vent the air. Roots blower is one of the type, the system is a volume rotary blower, the use of two leaf-shaped rotor in the cylinder for relative movement to compress and transport the gas rotary compressor. The blower has a simple structure and is easy to manufacture. It is suitable for gas delivery and pressurization at low pressure and can also be used as a vacuum pump.
Roots blower is the use of two leaf-shaped rotor in the cylinder for relative movement to compress and transport the gas rotary compressor. The compressor maintains the two rotors by the synchronizing gears on the rotor shaft end. Each concave curved surface of the rotor and the inner wall of the cylinder constitute the working volume, in the rotor rotation process from the suction port to take the gas, when moving to the exhaust near the exhaust port connected to the instantaneous, because of a higher pressure Of the gas reflux, then the working volume of the pressure suddenly increased, and then the gas delivered to the exhaust channel. The two rotors do not touch each other, between them tightly controlled by the gap to achieve the seal, so the exhaust gas from lubricating oil pollution.
Its biggest feature is the use of pressure when the allowable range to be adjusted when the flow of little change, a wide range of pressure selection, with a mandatory gas transmission characteristics. The medium is not oil when delivered. Simple structure, easy maintenance, long service life, the whole vibration is small.
Roots blower conveying medium for cleaning air, clean gas, sulfur dioxide and other inert gas, special gas industry (gas, natural gas, biogas, carbon dioxide, sulfur dioxide, etc.) and high pressure conditions of choice for products. In view of the above characteristics, which can be widely adapted to metallurgy, chemical, fertilizer, petrochemical, equipment, building materials industry.
