Operation and maintenance of Teflon lined centrifugal pump

Operation and maintenance of Teflon lined centrifugal pump:

-Teflon lined centrifugal pump operation:
(1) when shutting down, the valve at the outlet should be closed first, and then the power supply should be cut off.
(2) before starting the Teflon lined centrifugal pump, the pump should be filled with enough liquid to prohibit starting without liquid.
(3) the outlet valve is closed, the steering of the centrifugal pump can be checked immediately after being connected to the power supply, and the steering should be consistent with the arrow, and reverse operation is prohibited.
(4) after the start-up of the Teflon lined centrifugal pump, after reaching the normal speed, the outlet valve is gradually opened and adjusted to the required operating conditions for operation.

-Maintenance of Teflon lined centrifugal pump:
The main results are as follows:

(1) within one month of working in the Teflon lined centrifugal pump, the lubricating oil is changed after 100 hours, and the oil is changed every 500 hours thereafter.
(2) check whether the motor steering is correct. After the normal operation of the lining centrifugal pump, open the outlet pressure gauge and the imported vacuum pump to show the appropriate pressure, gradually open the gate valve and check the load of the motor at the same time.
(3) if the downtime is too long, the corrosive liquid in the pump should be discharged clean, the dirt of each part and the flow channel of the pump should be cleaned, and the power supply should be cut off in time.
