Roots blower should be fully filled with lubricating oil and grease before leaving the factory. After 6 months of normal operation, the transmission and bearing parts should be supplemented or replaced with grease. Assuming that the installation environment is high temperature or too much dust, the oil change time should be shortened. Roots blower is used for continuous work, allowing horizontal and vertical work. In the process of operation, it is assumed that air leakage or ash leakage occurs along the axial direction, The screw of the pressing cover can be closed or the asbestos packing can be replaced and then the pressing cover can be tightened.
Pay close attention to Roots blower so as to make full use of its characteristics to understand its application. The actual operation method is to fill the centrifugal blower with grease immediately, clean the pipeline and remove the filter in time, display the main parameters of the instrument panel, and handle abnormalities in time. Please check the Roots blower system preparator, and then make preparations.
Check whether the valve switches of the preparator are in place, and ensure that the outlet valve of Roots blower is fully closed and the inlet valve is fully opened. After the normal inspection, open the Roots blower reserve according to the operating regulations. At the same time, the standby fan of Roots blower is turned on and the fan in use stops. If the standby fan works normally. Slowly close the machine outlet and open the standby fan circuit. At the same time, gradually close the outlet valve of the fan to make the outlet pressure slightly higher than the original outlet pressure. Stop the working pressure at the fan outlet.
While performing the above tasks, gradually close the fan outlet valve when using it. Use the fan outlet valve to make the outlet pressure slightly higher than the original outlet hole to apply pressure. During the whole process, keep the air and pressure outlet to ensure the pressure balance and possible system pressure stability. Gradually use the auxiliary line valve and outlet valve of Roots blower. Fully close, and the auxiliary line valve and outlet valve of the standby Roots blower are fully opened. By this time, the machine has stopped running and the Roots blower has been switched.
1. The control handle of Roots blower control cabinet on the manual gear is used to close the suction inlet valve of Roots blower and the diaphragm of vacuum system.
2. The front water of the main engine and intermediate pump shall be used to flush the pump, and the pump shall be stopped periodically, so as not to mistake the shutdown sequence for fear of damaging the machine.
3. When stopping the front water flushing pump, first open the dirty discharge valve of the buffer tank of the water flushing pump, and then close the pump.
I believe that after reading the above contents, you should also know the correct shutdown method of Roots blower. I hope it will be helpful to you.
