1、根據(jù)污水處置站的來分析一下羅茨風(fēng)機的工作原理,輸送的風(fēng)量與轉(zhuǎn)速成比例,羅茨風(fēng)機為容積式風(fēng)機。三葉型葉輪每轉(zhuǎn)動一次由2個葉輪進行3次吸、排氣,與二葉型相比,氣體脈動變少,負荷變化小,機械強度高。
1. First, analyze the working principle of Roots blower according to the energy conservation of the sewage disposal station. The delivered air volume is proportional to the speed. Roots blower is a volumetric fan. Two impellers suck and exhaust gas for three times every time the three blade impeller rotates. Compared with the two blade impeller, the gas pulsation is less, the load change is small, and the mechanical strength is high.
2、兩根平相行的軸上設(shè)有2個三葉型葉輪,輪與橢圓形機箱內(nèi)孔面及各葉輪三者之間始終保持微小的間隙,由于葉輪互為反方向勻速旋轉(zhuǎn),使箱體和葉輪所包圍著的量的氣體由吸入的一側(cè)輸送到排出的一側(cè)。
2. Two three blade impellers are set on the two parallel shafts, and there is always a small gap between the wheel and the inner hole surface of the oval case and between the impellers. Because the impellers rotate at a constant speed in opposite directions, the amount of gas surrounded by the case and the impeller is transmitted from the suction side to the discharge side.
3、各支葉輪始終由同步齒輪保持正確的相位,不會出現(xiàn)互相碰觸現(xiàn)象,因而可以高速化,不需要內(nèi)部潤滑,而且性能穩(wěn)定,運轉(zhuǎn)平穩(wěn),結(jié)構(gòu)簡單,適應(yīng)多種用途,已運用于廣泛的領(lǐng)域。
3. Each impeller is always kept in the correct phase by the synchronous gear, without touching each other, so it can be high-speed, does not need internal lubrication, and has stable performance, stable operation, simple structure, and is suitable for a variety of purposes. It has been used in a wide range of fields.
4、羅茨風(fēng)機通過改變風(fēng)機出口的閥門開度來調(diào)節(jié)風(fēng)量或通過改變水泵入口管路上的調(diào)節(jié)閥開度來調(diào)節(jié)給水量。而風(fēng)機和水泵的特點是負載轉(zhuǎn)矩與轉(zhuǎn)速的平方成正比,通常污水處置系統(tǒng)上的羅茨風(fēng)機、水泵都是電機以定速運轉(zhuǎn)。
4. Roots blower regulates the air volume by changing the opening of the valve at the outlet of the blower or regulates the water supply by changing the opening of the regulating valve on the inlet pipe of the water pump. The characteristic of fans and water pumps is that the load torque is proportional to the square of the speed. Usually, Roots fans and water pumps in sewage disposal systems are all operated at a constant speed.
5、而軸功率與轉(zhuǎn)速的立方成正比,因此如將電機的定速運轉(zhuǎn)改為根據(jù)需要的流量來調(diào)節(jié)電機的轉(zhuǎn)速就可節(jié)約大量的電能。污水處置系統(tǒng)中,羅茨風(fēng)機的主要作用是給生化系統(tǒng)沖氧,使生化系統(tǒng)有充足的氧氣,生化池里放一個在線溶氧儀,溶氧儀上設(shè)定水。
5. The shaft power is proportional to the cubic speed, so if the motor is operated at a constant speed and the motor speed is adjusted according to the required flow, a large amount of electric energy can be saved. In the sewage disposal system, the main function of Roots blower is to flush oxygen to the biochemical system, so that the biochemical system has sufficient oxygen. An online dissolved oxygen meter is placed in the biochemical tank, and water is set on the dissolved oxygen meter.
