Roots blower It is a positive displacement fan, and the air volume delivered is proportional to the number of revolutions. Two impellers suck and exhaust three times every time the three blade impeller rotates. Compared with the two blade type, the gas pulsation is small, the vibration is small, and the noise is low. There is always a small gap between the impeller on the two shafts of the fan and the hole surface in the elliptical housing, between the impeller end face and the front and rear end covers of the fan, as well as between the fan impellers. Driven by the synchronous gear, the air is transported from the air inlet of the fan to the exhaust side along the inner wall of the housing. The fan cavity does not need lubricating oil, has simple structure, smooth operation, stable performance, and is suitable for many purposes, and has been used in a wide range of fields.

High efficiency and energy saving, high precision, low noise, long life, compact structure, small size, light weight, easy to use, products are widely used in petrochemical, building materials, electricity, smelting, fertilizer, mines, ports, light textile, food, paper making, aquaculture and sewage treatment, environmental protection industry and many other fields, most of which are used to transport air, but also can be used to transport gas, hydrogen Acetylene, carbon dioxide and other flammable, explosive and corrosive gases.

Due to the adoption of a three blade rotor structure and a reasonable structure at the inlet and outlet of the housing, the fan has low vibration and noise. The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan is permanent and can operate continuously for a long time. The fan has large volume utilization rate, high volume efficiency, compact structure and flexible installation mode. The selection of bearings is more reasonable, and the service life of each bearing is even, thus extending the life of the fan!

What are the operating requirements of Roots blower, and what conditions are required for the installation and operation of Roots blower

When using Roots blower, certain rules should be followed. The negative side is likely to have a bad impact on the Roots blower and damage the Roots blower. Here, I will briefly explain the operating requirements of Roots blower.

1. The inlet air temperature of the conveying medium shall not exceed 40 ° C.

2. The particle content in the medium shall not exceed 100mgm3, and the maximum particle size shall not exceed half of the minimum working gap.

3. During operation, the bearing temperature shall not be higher than 95 ° C, and the lubricating oil degree shall not be higher than 65 ° C.

4. The operating pressure shall not be higher than the pressure rise range specified on the nameplate or the pressure rise range specified in the performance table of this manual.

5. The clearance between fan impeller and casing, impeller and impeller has been adjusted when leaving the factory, and the clearance shall be ensured when reassembling. Excessive clearance affects performance. If the clearance is too small, friction and collision will occur due to thermal expansion.

6. When the blower is running, the oil level of the main oil tank and auxiliary oil tank must be between the two meridians of the oil level gauge.
