What's the seal water? What about the water seal?
When the loss of seal water, to make the high pressure water pump inside through the pump shaft and the seal gap between the leakage, resulting in a large number of refrigerant loss; the water temperature of the high temperature at the same time will pass through the bearing shaft and the pump body of the metal, the bearing temperature rise, which can even make the bearing burned; high speed bearing the rotation and seal between the gap is very small, when the loss of sealing water, water film here is destroyed, and the shaft seal is likely to increase the friction, the vibration of the feed pump, which will cause equipment damage and outage.The function of water seal trough is to maintain the tightness of the lower part of the furnace and to prevent the air from leaking into the air.
The function of sealed water is:1 high pressure water, water pump inside, even after the seal but there is still a certain pressure, in order to keep the water pump in the water through the shaft and seal gap between the leakage from the condensate pump outlet, or a water seal water in addition to lead as saline parent tube!2, water supply and the water pump is a high temperature water, the temperature will be passed to the pump body through a rotating shaft or bearing metal pump, the bearing temperature, in order to control the temperature outside so the seal also plays a role in cooling water.
Seal water is to pump the water seal way, in operation the seal water pressure difference, mainly depends on the seal water to enter the water pipe's seal water control valve to carry on the automatic adjustment. The seal groove is arranged in the ash bucket of the lower box, the lower part of the length of a steel plate. Steel plate with displacement in the header, but still not out of the water, this is the one hand to ensure the water wall expansion free, and ensure good sealing process of expansion.
