Pneumatic Transmission Rotary Screw Blower Integrated Screw Air Blower 55KW

55KW 24-58 m³/min Integrated Screw Air Blower for Pneumatic Transmission in Textile Industry

Description

The screw blower is a kind of new blower with the virtues of both screw compressor and roots blower, which can be applied for many kinds of gas transferring in the fields. And with the continuous development of science and technology, users have higher and higher requirements for the blowers. In terms of the current development trend of fan, blowers will be designed and developed with characteristics of higher efficiency, smaller size and making lower noise.

Advantages and disadvantages of Roots Blower and Centrifugal Blower

The advantage of Roots blower is that when the rotation speed is fixed and the inlet pressure slightly fluctuates, the exhaust volume remains the same, the relationship between the rotation speed and the exhaust volume remains constant positive ratio, with the characters of high rotation speed, no air valve and no crankshaft, the roots blower is light in weight, and is convenient for application. In addition, roots blower also has the advantages of forced gas transmission, no oil pollution of discharged gas, simple structure, easy manufacturing and easy maintenance.

Roots blower has the following defects: the gas pressure in Roots blower is not increased due to volume reduction, but by means of gas reflux with higher pressure in the exhaust port to improve the gas pressure in the cylinder cavity. Therefore, the efficiency of Roots blower is generally lower than other kinds of blowers with internal compression. Moreover, due to the periodic suction and exhaust, and instantaneous volume compression of Roots blower, the pulsation of air flow velocity and pressure will be formed, which will produce large aerodynamic noise.

The advantages of centrifugal blower are large and continuous gas transmission, stable operation, small unit size, few wearing parts, minimum maintenance work and long service life. 

The disadvantages of centrifugal blower are that the friction loss between the gas and the impeller surface is large at high speed, and there is also pressure loss when the gas flows through the diffuser, bend and reflux, so the efficiency is low, small pressure adaptation range which may result in surge.

Application

Screw air blower belongs to displacement blower, it is widely used in sewage treatment, desulfurization and oxidation, pneumatic conveying and other fields. In aeration field, the screw air blower can automatically adjust its pressure according to the change of water depth, while maintainin stable flow rate, which is suitable for medium&small air volume needs and harsh environment working conditions. With the characteristics of wide working pressure adjustment range, strong dust resistance, high efficiency and stability, can start-stop frequently and high cost performance, the screw air blower is the most economical blower for the reform of the Roots Blower.
