1、根据污水处置站的来分析一下罗茨风机的工作原理,输送的风量与转速成比例,罗茨风机为容积式风机。三叶型叶轮每转动一次由2个叶轮进行3次吸、排气,与二叶型相比,气体脉动变少,负荷变化小,机械强度高。
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、两根平相行的轴上设有2个三叶型叶轮,轮与椭圆形机箱内孔面及各叶轮三者之间始终保持微小的间隙,由于叶轮互为反方向匀速旋转,使箱体和叶轮所包围着的量的气体由吸入的一侧输送到排出的一侧。
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、各支叶轮始终由同步齿轮保持正确的相位,不会出现互相碰触现象,因而可以高速化,不需要内部润滑,而且性能稳定,运转平稳,结构简单,适应多种用途,已运用于广泛的领域。
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、罗茨风机通过改变风机出口的阀门开度来调节风量或通过改变水泵入口管路上的调节阀开度来调节给水量。而风机和水泵的特点是负载转矩与转速的平方成正比,通常污水处置系统上的罗茨风机、水泵都是电机以定速运转。
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、而轴功率与转速的立方成正比,因此如将电机的定速运转改为根据需要的流量来调节电机的转速就可节约大量的电能。污水处置系统中,罗茨风机的主要作用是给生化系统冲氧,使生化系统有充足的氧气,生化池里放一个在线溶氧仪,溶氧仪上设定水。
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.
