Key words: Roots blower

   Roots blower It is widely used in the aeration of sewage treatment. There may be insufficient aeration in the process of use. Through years of time, Hongguang Xiaobian summarized the following main reasons:

1、 Check valve problem

One way valve is a one-way valve, is to avoid gas backflow, impurities into the fan and equipped with safety protection device. Due to the one-way valve and pipe flange connection is a rubber seal ring to ensure sealing. When the pressure in the fan pipe is low, it will leak, but it will open when the pressure is high; after the fan is turned off, the negative pressure valve in the pipe will be closed. When installing, pay attention to the outlet direction of one-way valve. If it is installed reversely, the air can not be discharged. Not only is aeration not successful, but also the motor may be burned out!

2、 Wrong selection

If Roots blower It is a normal phenomenon that the type selection is wrong, the air volume and pressure are insufficient, and it is a normal phenomenon that the aeration cannot be realized. For example, we need a fan with a pressure of 44.1kpa for aeration. When the pressure is selected to be small, it is normal that the fan is overloaded and the motor is over current; if the air volume is too small, the aeration intensity in the aeration tank is not enough or local aeration is caused.

3、 Pipeline problems

in use Roots blower Pipeline problems often occur, such as: inlet filter plugging, outlet pipeline plugging, pipeline leakage, pipeline damage, pipeline too long, too many elbows, too small pipe diameter, etc., will cause the corresponding problems of the system.

4、 Fan fault

   Roots blower The longer the fan is used, some parameters of the fan will have problems, such as insufficient air volume and insufficient pressure. These are normal phenomena. Because roots blower will wear during use, the longer it is used, the greater the probability of parameter deviation.

5、 Circuit problems

The wrong wiring mode of the motor causes the motor can not start or the current is abnormal, the wrong direction of the motor causes the fan to reverse, and the aging of electrical components causes the output voltage to be over-voltage
 Roots blower

It is reported that, Roots blower Most of the use of aquaculture, sewage treatment and other industries, then, if the internal water we should how to deal with? Small make up for you to introduce.

In general, Roots blower The most reasonable structure of the air outlet of the three blade rotor is adopted, so the probability of water entering the cavity is very small during operation, but there will be a lot of water entering into the cavity when using, which will cause mechanical damage and even affect our normal work. In the face of this problem, we have taken a series of protective measures, including the use of strict protective structure measures To a certain extent, these measures are also effective Roots blower Protection measures have been taken, but in case of water, we will take apart the machine for cleaning, so dismantle Roots blower During cleaning, not only the water should be removed, but also some parts should be dried. Many internal parts of the fan will change after meeting water, and the internal parts will rust after meeting water, so we must pay attention to these problems in future use. Try to avoid water entering Roots blower Inside.
