Roots blower is a positive displacement fan, which is forced to transport gas when transporting gas. That is to say, if we need to overcome the pressure of 9.8kpa in our working condition, we will make Roots blower to overcome the pressure of 9.8kpa for you. If we need to overcome the pressure of 98kpa in our working condition, we will make Roots blower to overcome the pressure of 98kpa for you. You may ask, can't I purchase a high pressure machine directly to meet many pressure ranges? Theoretically, it is feasible and completely feasible, but in general, this theory is unscientific. Why? Roots blower is a high consumption equipment, which costs a lot of electricity. If we only want to overcome the pressure of 9.8kpa, we have purchased a fan that can overcome the pressure of 98kpa, and the energy consumption will be more than 10 times. Therefore, we need to purchase the best matching Roots blower.
After the pressure of roots blower is increased, the matching motor power is also increased. That is to say, if roots blower wants to increase the "pressure", the motor power must be increased. The higher the motor power is, the higher the pressure of roots blower is. This is only from the selection sample, and it is a horizontal comparison under the same speed and model.
Insufficient pressure of roots blower may cause the following:
1. First, determine whether the motor wiring is correct. If it is reversed, the air outlet will become an air inlet. Generally, a check valve will be installed at the outlet. At this time, the negative pressure will rise and the current will be overloaded;
2. The pressure of Roots blower is reflected by the air outlet resistance at the rear end. If the air outlet is open, the pressure gauge will not be able to display the pressure at this time, because there is no pressure in the pipeline, and the compressed air is completely exhausted. You can slowly reduce the outlet valve to observe whether the pressure of the pressure gauge has risen. The maximum pressure should not exceed the pressure marked on the equipment, Avoid motor overload;
3. If the direction of the blower equipment is normal, the output pressure cannot meet the use requirements, and the motor has been overloaded, then it can be determined that the motor is small and the power is insufficient, and it needs to be added to the motor power to increase the higher pressure. Under normal conditions, as long as the quality of the fan is normal, it will not fail. The quality is mainly related to the brand. The big brands such as Beside and Jingong are generally OK. In a word, if you choose a good fan, master the basic knowledge of maintenance, and do a good job of maintenance in time, there will be no problem of insufficient pressure.
How to increase the pressure of roots blower:
1. First determine whether the motor wiring is correct. If it reverses, the air outlet will become the air inlet, and a check valve will be installed at the air outlet. At this time, the negative pressure will increase and the current will be overloaded;
2. The pressure of roots blower is reflected by the air outlet resistance at the rear end. If the air outlet is open, the pressure gauge will not display the pressure at this time. Since there is no pressure in the pipe, the compressed air will be completely drained, which may slow down. Slowly decrease the outlet valve to observe whether the pressure on the pressure gauge increases. Do not exceed the pressure marked on the equipment to avoid overloading the motor;
3. If the direction of roots blower device is normal, the output pressure does not meet the use requirements, and the motor is overloaded, it can be determined that the selected motor is small and the power is insufficient. It needs to be added to the motor power to increase the higher pressure. Generally, as long as the quality of the fan is acceptable, there is basically no failure.
I believe that after reading the above contents, you should also understand the method of increasing the pressure of Roots blower. I hope it will be helpful to you.
