If the power switch is directly plugged in, it is easy to cause failure or the motor is burned out. Fully open the inlet valve and fully close the outlet valve of Roots blower, start the motor, gradually open the outlet valve when the outlet pressure of Roots blower is higher than the operating pressure, adjust to the required flow, and make the pump operate normally. During the operation of Roots blower, it is necessary to regularly check whether the indicated values of pressure gauge and ammeter are normal, whether the bearing temperature is normal, and whether there are abnormal conditions such as vibration and noise.

Starting at Roots blower Before, please check the installation quality of each fastener and positioning bolt; Check the installation quality of inlet and outlet pipes and valves; Check whether the free space of the blower assembly meets the requirements; Check whether all parts around the assembly base are firm and whether the foundation bolts are fastened. Before operating the fan, proper lubricating oil must be added to the main oil tank and auxiliary oil tank, and the lubricating oil must be replaced every three months. Due to the pressure of the main oil tank and the auxiliary oil tank, the upper and lower oil covers of the main oil tank and the auxiliary oil tank must be tightened, or oil leakage will occur.

2. It is forbidden to close and start all the inlet and outlet valves during operation.

3. When Roots blower operates under rated conditions, the temperature rise of each rolling bearing shall not exceed 55 ℃, the maximum surface temperature shall not exceed 95 ℃, and the temperature of lubricating oil in the oil tank shall not exceed 65 ℃.

4. Regularly check the firmness of each part, especially the positioning pin, and there should be no looseness.

5. Regularly remove the dust from the filter or replace the filter material to avoid excessive dust content increasing the system resistance.

6. Keep the system clean to prevent foreign matters from entering the machine.

Roots blower stops:

1. The evacuation valve shall be opened, the equipment inlet valve shall be closed, and the outlet valve shall be closed at the same time. Note that the fan pressure shall not exceed the rated value.

2. Cut off the power supply and close the outlet valve of the fan after the motor stops running.

Matters related to regular inspection:

1. Daily regular inspection: check the pressure, noise and vibration;

2. Monthly regular inspection: add lubricating oil and butter, and clean the filter screen;

3. Regular inspection every 6 months: replace the lubricating oil and check the belt;

4. Annual regular inspection: replace the belt and filter screen;

5. Regular inspection every two years: replace bearings and check impellers and gears.

The above are some precautions for the starting of Roots blower. I believe you will also understand it after reading it. I hope it will be helpful to you.
