Boiler multistage pump mechanical seal on the seal water

Boiler on the multistage pump mechanical seal in order to protect the moving and static ring sealing surface are all need to cool the cooling, cooling two forms, a fluid leak within the pump to the mechanical seal, this part of the seal cooling water is relatively stagnant water, in order to make its temperature within a certain range will rely on the external cooler to cool, ring made in the form of a screw pump, to provide this part of the seal cooling water circulation cooling power.

boiler on the multistage pump mechanical seal sealing water:

1, in a sealed water passes through the seal water between the axis and seal water film formation, prevent leakage of the clearance between the shaft and here the seals, causing a large amount of working medium loss; At the same time, high temperature water through the pump shaft and the pump body metal heat transfer to bearing to bearing temperature. Serious when still can make bearing burned; Between the high-speed rotating shaft and seal clearance is small, when loss of seal water, the water film is destroyed, friction, shaft and seal is likely to make feed water pump vibration increases, serious when will cause equipment damage. Seal water backwater generally using multistage water seal tube into the condenser.

2, on the water pump is a certain temperature of the water in the water, hot water through the rotation of the pump or pump body metal heat passed on to the bearing, the bearing temperature rise. In order to control heat gaiden, so the water seal also play a cooling effect.

3, multi-stage pump in the high pressure water, after the seals, but still have certain pressure, in order not to pump water through the axis and seal the gap between the leaked out, and the export of the condensate pump or in addition to the brine mother tube take water as seal water.

there is a direct external cooling water, after cooling flow inside the pump, with the water pump fluid drain away.

Maintaining winter cover pump is not as easy as it may seem. You have to do plenty of important tasks. So cruel is the truth unless you've got a to help you.
It is clear that is one of the best methods that can be used for the purposes of pool cover drain pump. If you want an and other winter cover pump, you should find the right provider who will guide you through and offer something that will help your business. For quality , go to J&T INDUSTRY.
Using high-quality materials to produce submersible pump is one of the most important part during manufacturing.
