Background

The Roots blower belongs to a positive displacement blower, and the end faces of an impeller and front and rear end covers of the blower. The principle is a rotary compressor which compresses and conveys gas by utilizing the relative motion of two blade-shaped rotors in a cylinder. The blower has simple structure and convenient manufacture, is widely applied to aquaculture oxygenation, sewage treatment aeration and cement conveying, is more suitable for a gas conveying and pressurizing system in a low-pressure occasion, and can also be used as a vacuum pump and the like.

In projects with higher requirements, a mode of building a sound insulation room is generally adopted, the noise of the Roots blower is reduced, but the defects of high manufacturing cost, inconvenience in monitoring and maintenance and the like exist, and the sound insulation effect of the sound insulation room is not obvious. In the actual use of the sound insulation room, the internal temperature is higher, so that the problem of the reduction of the stability of the machine body is difficult to solve all the time, and the high-temperature gas can not be conveyed. The full-water-entry underwater roots blower gradually appears in the market, the underwater motor is directly connected with the roots blower, the inverted arrangement is adopted, the whole blower, the motor, the cable, the air inlet pipeline and the air outlet pipeline are arranged in a sewage tank together during use, and noise generated by a machine body is blocked by using a water body. Although water is still a good sound conductor, the problem of noise can be solved once and for all almost through vibration consumption, dissipation and refraction of multiple different media (air, metal and water) and media interfaces, environment-polluting noise reduction materials such as asbestos and the like are not needed, the temperature of a Roots blower body can be effectively reduced by water around a nose, bearings are protected, high-temperature gas delivery can be achieved, but the blower is completely soaked in a sewage pool without visibility, observation and maintenance are inconvenient, even if the blower needs to be lifted out of the water surface during the most daily oil change, lifting equipment needs to be installed during basic construction, and the investment of the basic construction is large.
