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.

由于設(shè)備運行環(huán)境等因素的影響，羅茨風(fēng)機廠家報價羅茨風(fēng)機經(jīng)常遭受軸頭和鍵槽的磨損。問題發(fā)生后，在修復(fù)焊接或刷鍍后通過常規(guī)方法進行修復(fù)。結(jié)論降低噪聲的更有用和經(jīng)濟的方法是使用新設(shè)計和新工藝進行有源降噪，以降低聲源的輻射噪聲，將多余的氣體置于大氣中或降低鼓風(fēng)機速度。用于微生物和酶和載體的自固定技術(shù)：（a）在污水處理廠中維持高濃度的生物質(zhì)，這可以增加處理負(fù)荷并減少處理裝置的體積， （b）選擇性地固定優(yōu)勢生物物種。

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.

高壓羅茨風(fēng)機的齒輪沒有牢固固定，葉輪不能保持同步。必須重新組裝齒輪并保持75％的錐形接觸面積。三葉羅茨風(fēng)機可以說是雙葉羅茨風(fēng)機的革命性改進。與兩片葉片相比，由于葉片形狀，三葉羅茨風(fēng)機優(yōu)于兩片葉片。如果風(fēng)扇可以正常驅(qū)動，風(fēng)扇不會損壞。如果磁盤沒有移動風(fēng)扇，那么風(fēng)扇也會出現(xiàn)問題。簡而言之，監(jiān)管的目的是滿足性能要求，擴展（穩(wěn)定）條件，脫硫用實現(xiàn)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.
