Desulfurization pump maintenance

The desulfurization pump is a type of slurry pump, but the slurry it transports is highly corrosive, so its flow parts are also made of corrosion-resistant materials, generally A49. The sealing method generally adopts mechanical seal. The maintenance of desulfurization pump is a very tedious matter, which is easy to be ignored during use. However, the maintenance of desulfurization pump is also a very important matter. If the maintenance is not in place, it will affect its service life and use effect. . Today Shijiazhuang Pansto Pump Industry will introduce to you the maintenance of desulfurization pumps.
Failure analysis of mechanical seal of desulfurization pump. Because the slurry transported by the desulfurization pump is generally corrosive, leakage is not allowed when used on site, so the sealing of the desulfurization pump is a very important part. The reasons for mechanical seal failure generally include the following: 1. Leakage of the dynamic and static ring sealing surfaces. 2. Compensation ring seal leaks.
What should be done after the desulfurization pump stops running? 1. After the desulfurization pump stops operating, the inlet valve should be closed. 2. The high-temperature pump should be stopped according to the regulations of the equipment technical documents. After stopping, it should turn half a circle every 20-30 minutes until the temperature of the pump body drops to 50 degrees. 3. When the cryogenic pump is stopped, when there are no special requirements, the pump should always be filled with liquid, and the suction valve and discharge valve should be kept normally open. For cryogenic pumps that use double-end mechanical seals, the liquid level controller and pump sealing fluid should keep the pump open. grouting pressure. 4. Pumps that transport media that are easy to crystallize, solidify, or precipitate should prevent clogging after stopping the pump, and flush the pump and pipes with clean water in a timely manner. 5. Drain the liquid accumulated in the pump to prevent corrosion and frost cracking.
