Today, Xiaobian continue to talk about corrosion-resistant submersible sewage pump for everyone, the following to say is also very important, involving mechanical seals. Mechanical seal of the high-precision, reasonable structure, the correct installation of the seal on the corrosion-resistant submersible sewage pump plays an important role. Next, let's take a look at ways to improve the reliability of mechanical seals for corrosion-resistant submersible sewage pumps. Improve corrosion-resistant submersible sewage pump mechanical seal reliability 1, mechanical seal pressure relief technology Mechanical seal pressure relief technology refers to the mechanical seal to withstand the seal pressure from the head to reduce the pressure formed into the water pressure into the pool, PTEE crowded seal and the mouth ring seal, the pump high pressure chamber into the first mechanical seal cavity leakage reduced. Pressure relief hole is set in the upper part of the first mechanical seal cavity, and the pressure relief hole is communicated with the inflow channel. The flow resistance is less than the flow resistance of the PTEE displacement type seal. After the pressure relief device is set, the pressure in the first channel seal cavity is reduced by the pressure generated by the lift and reduced to the pressure generated by the submerged depth of the water pool. Since the PTEE displacement type seal is provided, Leakage is small and does not affect pump flow. 2, the combination of mechanical seal inside the oil chamber (media for the mechanical oil) and the external (medium for the sewage), set up in series with two mechanical seals (ie oil chamber mechanical seal), on the one hand reduce the mechanical seal accidental occurrence Of the probability, on the other hand to further reduce the pressure difference, help to reduce the leakage of mechanical seals. 3, the mouth ring and PTEE crowded seal set mouth ring, so that the mechanical seal with a pressure relief device can completely exclude the plastic bags in the sewage, hemp rope and other debris wrapped around the mechanical seal on the possibility of improving the mechanical seal Working conditions. At the same time, to prevent the formation of fibrous plugging in the sealed chamber expansion thrust axial force increases damage the thrust bearing phenomenon. PTEE displacement type seal set to reduce leakage, and adapted to high temperature, corrosive fluids, abrasive fluids containing harsh conditions, such as sealing, long life. The above is to improve the reliability of corrosion-resistant submersible sewage pump seal method of introduction, do not know if you understand yet? Mechanical seal on the corrosion-resistant submersible sewage pump is very important, the equipment can not work well with a great relationship, so the mechanical seal must have enough effort on the issue.
