​Roots blower consists of five parts: shell, wall plate, impeller, oil tank and muffler. Casing: it mainly supports (wallboard, impeller, muffler) and fixes.

Since the impeller of the air blower operates in the body without friction and needs no lubrication, the discharged gas does not contain oil. It is an ideal pneumatic conveying gas source for chemi...

​The main products of domestic centrifugal fan manufacturers include large-scale industrial blowers, fans, gas blowers, coke oven blowers, multi-stage high-pressure centrifugal blowers, single-stag...

Centrifugal fan is a complex structured device, which is mainly composed of air inlet, air valve, impeller, motor and air outlet. The effects of centrifugal fans are different in different states.

For the centrifugal fan assembled on site, the cutting surface on the base should be properly protected from rust or operation. When the base is placed on the foundation, a pair of oblique horns sh...

​With the advancement of China's industrialization process, the industrial industry is vigorously carrying out energy conservation and consumption reduction, industrial upgrading and integration an...

During the trial run of the unit, if any of the following situations occur, it should be immediately stopped immediately. The operation of emergency stop is to press the stop button of the main mot...

​Centrifugal fan drive parts wear is a common equipment problem, including exhaust fan bearing position, bearing room wear, blower shaft bearing position wear and so on.

​The centrifugal fan is essentially a variable flow constant pressure device. When the speed is constant, the theoretical pressure-flow curve of the centrifugal fan should be a straight line.

Its impeller and casing are concentric, and the casing is made of brick. The wooden impeller uses backward straight blades, which has an efficiency of only about 40%. It is mainly used for mine ven...

Chassis: Made of steel plate, it is sturdy and reliable. It can be divided into integral type and semi-open type. The semi-open type is convenient for maintenance.

​The working principle of the centrifugal fan is basically the same as that of the turbo compressor. Both are due to the low gas flow rate and small pressure change.
