We all know that flushing water needs to be added when using mechanical seals. Do you all know the function of flushing water?

The main functions of mechanical seal flushing water are:

1. Take away the heat generated by the sealing friction pair. If the temperature of the conveying medium is higher, the temperature in the sealing cavity can be kept at a lower temperature;
2. If the conveying medium contains solid particles, it can prevent the particles from entering the friction pair and damaging the seal;
3. If the conveying medium is easy to crystallize, it can reduce the crystallization at the friction pair and elastic components.

The seal flushing water should be process water or industrial water with a pressure higher than the pressure inside the pump to prevent fluid from flowing out and play a cooling and sealing role. It is also commonly known as seal cooling water. When the sealing device is damaged or the cooling water pressure is low or the water cutoff equipment is running, it is easy to cause the mechanical seal to loosen, materials leak from the pump shaft and mechanical seal, and even damage the mechanical seal and pump shaft.

If the sealing water is cut off, you should immediately check whether the valve has been closed by mistake. If the amount of sealing water cannot be guaranteed, stop the pump for inspection and restart the equipment after recovery.
