Key words: Roots blower

People are using it Roots blower Once this happens, most users will call to reflect that the air volume of the fan is too small, and the effect is not good. In practice, Hong Guang's editor has made several introductions to this problem

1、 Wrong selection

If the user in the design and practice of the error will first encounter the selection error, then the air volume and pressure is insufficient, the air volume is small is the normal phenomenon. For example, we design the pressure of 49kpa Roots blower We choose aeration according to this value, but in actual use, when the pressure reaches 58.8kpa, the motor will be overloaded and over-current will occur; the air volume of the corresponding fan will also be reduced, which will lead to insufficient aeration intensity or a small number of aeration bubbles in the aeration tank.

2、 Check valve problem

One way valve is a kind of safety protection device, which can avoid gas backflow and foreign matters from entering the fan. Because there is a rubber sealing ring at the joint between the check valve and the pipe flange to ensure the sealing. Roots blower When the pressure of the pipeline is low, it will open when the pressure is high; after the fan is turned off, a negative pressure valve is formed on the pipe to close it. When installing, please note that the outlet direction of the single return valve should not be reversed. If it is installed reversely and the gas cannot be discharged, not only the aeration is not successful, but also the motor may be burned out!

3、 Fan failure

   Roots blower The longer the use time, some parameters of the fan will have problems, such as insufficient air volume, insufficient pressure, etc. This is normal because Roots blower It will wear and tear during use, so Roots blower The longer the use time, the greater the chance of insufficient air volume.

4、 Pipeline impact

use Roots blast When the machine is running, there are often pipeline problems, such as: inlet filter blockage, outlet pipe blockage, leakage pipeline, damaged pipeline, too long pipeline, too many elbows and too small pipe diameter, etc., which is the problem of its own system.

5、 Circuit problems

The wrong wiring method of the motor will cause the motor can not start or the current is abnormal, the wrong rotation of the motor will cause the fan to reverse, and the aging of the electrical components will cause the output voltage to be too low.

The above is the summary of the small series in practice, when the user in the process of the use of insufficient air volume fault, please refer to the above summary, patiently find out the cause and do troubleshooting, if you can not find the reason, please call our customers, we will help to find out the problem, and finally eliminate, so that it can better serve us.
