Roots blowers are mainly vertical and horizontal. The vertical roots blower is characterized by that the centers of two roots rotors are located on the same vertical plane, and the air inlets and outlets are located on both sides of the blower. The horizontal roots blower has two rotors located in the center of the same horizontal plane. Its air inlet is located at one side of the lower base of the blower, and its air outlet is located at the upper side of the blower.
Why is Roots blower afraid of sudden power on? If the switch is open and suddenly power on, it may not start. Because when Roots blower starts, it needs to open the vent valve first, then slowly close the vent valve, gradually boost the fan, and finally close the vent valve.
The accessories that must be installed for Roots blower: check valve. Once the Roots blower is powered off and there is no check valve, the impeller of Roots blower will be directly damaged. We have also encountered such accidents many times, some impellers are severely damaged, and some have abnormal noise.
1. Turn off the switch and check the fan
After the sudden power failure of Roots blower, the power supply of the blower shall be cut off in time. Do not start the blower before inspection. After the power failure of Roots blower, first cut off the main switch of the blower power supply, and then check the blower to see if there is any abnormality.
2. Close the pipeline gate valve
The gate valve of the pipeline connected to the fan shall be closed to avoid the continuous backflow of gas. Because the conditions of each working condition are different, such as: some working conditions transport expensive rare gas, this step can be upgraded to the first step to avoid waste of resources, and then turn off the fan switch.
3. Open the vent valve
The main purpose of opening the vent valve of the fan is for trial operation. Before the health level of the fan is confirmed, it is necessary to conduct trial operation for Roots fan, and then start the machine after the trial operation.
4. Check valve inspection
If the fan is powered off, the gas will flow back. The friend who installs the check valve also needs to check the check valve of the pipeline to see if it works.
5. Restart precautions
The Roots blower must be checked if it reverses due to sudden power failure. Before starting, it is necessary to carry out trial operation, and start again if there is no problem in the trial operation.
If the Roots blower reverses, what needs to be done is to install a check valve on the pipeline to prevent backflow of gas and damage the impeller. If Roots blower delivers special gas, safety confirmation must be carried out before starting to avoid safety accidents.
In case of power failure of Roots blower, it is necessary to find out whether it is caused by plant power failure or line aging. If it is a line fault, it is necessary to disconnect the main switch to check the line, understand the problem, clean the existing problems and faults, and then turn over the power supply.
I believe that after reading the above, you should also know how to solve the power failure problem of Roots blower. I hope it will be helpful to you.
