The pressure range of Roots compressor is 9.8kpa-200kpa. The pressure beyond this range can be selected from rotary blower and centrifugal blower. It can be said that in any case, the grain fans can not achieve suction by reversing their inlet and outlet, so it is useless to directly reverse the connection. Don't just understand this. This is also the meaning of wind, which means the meaning of pressure. The general unit is: kpa, the meaning of motor power, the required power, the meaning of speed, and R is also the meaning of caliber. It is also used for: the drilling unit is: mm Roots blower in the selection.

由于设备运行环境等因素的影响，罗茨风机厂家报价罗茨风机经常遭受轴头和键槽的磨损。问题发生后，在修复焊接或刷镀后通过常规方法进行修复。结论降低噪声的更有用和经济的方法是使用新设计和新工艺进行有源降噪，以降低声源的辐射噪声，将多余的气体置于大气中或降低鼓风机速度。用于微生物和酶和载体的自固定技术：（a）在污水处理厂中维持高浓度的生物质，这可以增加处理负荷并减少处理装置的体积， （b）选择性地固定优势生物物种。

Due to the influence of equipment operation environment and other factors, Roots blower manufacturers quote that Roots blower often suffers from wear of shaft head and keyway. After the problem occurs, it shall be repaired by conventional methods after repair welding or brush plating. Conclusion The more useful and economical way to reduce noise is to use new design and new technology to actively reduce noise, so as to reduce the radiation noise of the sound source, put the surplus gas in the atmosphere or reduce the blower speed. Self immobilization technology for microorganisms, enzymes and carriers: (a) maintain high concentration of biomass in sewage treatment plants, which can increase the treatment load and reduce the volume of treatment devices, and (b) selectively immobilize dominant biological species.

高压罗茨风机的齿轮没有牢固固定，叶轮不能保持同步。必须重新组装齿轮并保持75％的锥形接触面积。三叶罗茨风机可以说是双叶罗茨风机的革命性改进。与两片叶片相比，由于叶片形状，三叶罗茨风机优于两片叶片。如果风扇可以正常驱动，风扇不会损坏。如果磁盘没有移动风扇，那么风扇也会出现问题。简而言之，监管的目的是满足性能要求，扩展（稳定）条件，脱硫用实现并防止浪涌。

The gear of high-pressure Roots blower is not firmly fixed, and the impeller cannot keep synchronous. The gear must be reassembled and 75% of the tapered contact area must be maintained. The three leaf roots blower can be said to be a revolutionary improvement of the double leaf roots blower. Compared with the two blades, the three blade Roots blower is better than the two blades due to the shape of the blades. If the fan can be driven normally, the fan will not be damaged. If the disk does not have a moving fan, the fan will also have problems. In short, the purpose of supervision is to meet performance requirements, expand (stabilize) conditions, and achieve energy conservation and prevent surges for desulfurization.
