Is the price of twin series Roots blower high? How much is it?

Double stage series Roots blower Because it is suitable for the environment with high pressure and high air volume, the production process is relatively complicated, and the raw materials are also expensive, so the price will be higher.

First, let's analyze the characteristics of two-stage series Roots blower:

This Roots blower has the advantages of high volumetric efficiency, stable operation, reliable use and relatively stable working performance. The impeller and shaft have an integral structure, and the impeller is not worn. The fan has constant performance and can operate continuously for a long time. It is also a forced gas transmission. The flow changes little with the pressure. The outlet pressure is determined by the pressure on the back. The transported gas is not polluted by oil.

In addition, the selection of bearings for Roots blower parts is reasonable, and the service life of each bearing is even. The fan oil seal is made of imported fluororubber material, which is resistant to high temperature and abrasion. Roots blower has a long service life and high reliability.

The two-stage series Roots blower has large volume utilization rate, high volume efficiency, simple and compact structure, flexible installation, easy use and maintenance. Due to the structure of three blade rotor and the structure of the air inlet and outlet of the casing, the fan has low vibration and noise. Pressure and temperature control provides protection for operating the unit.

Design structure characteristics of two-stage series Roots blower:

The fundamental way to reduce noise of Roots blower The noise control method is to try to avoid and reduce the noise radiation generated by the noise source, that is, to reduce the impulse force as much as possible. Usually Roots blower manufacturer The noise control method adopted not only increases the investment, but also causes energy loss due to the pressure loss of the muffler during the operation of the fan, which is very unfavorable for energy saving. Therefore, the fundamental way to reduce the noise of Roots blower is to improve the aerodynamic design of the blower, make a good selection of the blower, and adopt appropriate installation and operation modes.

The two-stage series Roots blower has a compact structure, which greatly saves space and can be customized according to demand. Compared with the traditional Roots blower, it is more flexible.
