How To Maintain The Fluoroplastic Self-Priming Pump After It

How To Maintain The Fluoroplastic Self-Priming Pump After It Stops Working?

Operation method after the fluoroplastic self-priming pump stops working
1. After the fluoroplastic self-priming pump stops running, the pump inlet valve should be closed, and the valves of the auxiliary system should be closed in sequence after the pump cools down.
 
2. The shutdown of the high-temperature pump should be carried out in accordance with the provisions of the equipment technical documents. After the shutdown, the pump should be turned half a circle every 20-30 minutes until the pump body temperature drops to 50°C.
 
3. When the low-temperature pump is stopped, if there is no special requirement, the pump should always be filled with liquid; the suction valve and the discharge valve should be kept open; for low-temperature pumps with double-end mechanical seals, the sealing liquid in the liquid level controller and the pump sealing cavity should maintain the pump grouting pressure.
 


Precautions after the fluoroplastic self-priming pump stops working

1. Centrifugal pumps that transport media that are easy to crystallize, solidify, and precipitate should be prevented from clogging after stopping the pump, and the pump and pipeline should be flushed with clean water or other media in time.
 
2. Drain the liquid accumulated in the pump to prevent rust and freezing cracking. For spare pumps during the shutdown period, the quality and quantity of lubricants should be checked regularly. The pump body and the medium in the pump should be heated and insulated. In order to prevent the rotor from bending due to its own weight: in order to prevent the shaft and bearing from sticking and causing difficulty in starting, the spare pump should be turned regularly. For centrifugal pumps that have been out of service for a long time, the plug on the pump body should be opened and the liquid in the pump should be drained to prevent the pump body from being damaged by freezing in cold weather. If necessary, open the pump body, clean the internal parts, and apply anti-rust oil.
 
Storage method of fluoroplastic self-priming pumps after stopping working
1. For pumps that have been out of service for a long time, whether they are on site or in a warehouse, they should be turned regularly.
 
2. When the centrifugal pump is working, the pump needs to be placed on land, the suction pipe is placed in water, and the pump needs to be filled and started.
 
3. Due to structural limitations, the motors of mud pumps and submersible centrifugal pumps need to be placed above the water surface when working, and fluoroplastic pumps are placed in the water, so they must be fixed, otherwise the motor will fall into the water and cause the motor to be scrapped. In addition, since the length of the major axis is generally fixed, the installation and use of the pump is more troublesome, and the application occasions are subject to many restrictions.
