What is boiler feed water pump warm up
Now the performance of the pump material are good, basically no warm pump system, and improve the reliability of the device, reducing the complexity of the system, and now the domestic pump material performance are good + dynamic clearance gap, so basically no warm pump System, but because of the import of the pump to move the gap between the small high efficiency, spare pump must be warm pump, but also consider the upper and lower temperature of the pump casing in the control requirements.
Upside down can be recovered quality, so there is a pump running standby pump are used to warm up. Now a lot of pumps do not have a warm pump, not because it is not imported pump, and material and structure are related to it!
Is warm and warm should not be much difference, all from the role of warm pump, the general situation, the initial start of the pump, to use the warm, as a backup pump, when there are other pumps running, to start the pump, Use upside down.
Feed pump is warm and Feed pump warm up difference:
1, is warm from the entrance door side of the water for the warm pump (open the entrance door, the pump water door, after the end of the warm water shut the door);
2, is warm all the pumps are in the stop, if ready to start an electric (steam) to the pump when the deaerator water tank in the deaerator pressure and the water tank under the action of static pressure, given to Pump inlet, through the pump body, from the pump outlet end to the condensate recovery tank.
3, is warm generally used in the pump, the steam pump before the pump through the recirculation is back to the oxygen is warm, or from the entrance into the warmth of the way is warm, from the export into the warm jump to warm.
4, the warmth is from the exit door side of the water for the warm pump (in general, the old unit of the electric pump, are equipped with a warm pump door, is connected with the exit after the door connected to the water, the open pump Electric door, exit the door after the door, and the warm pump door and pump the water gate, after the end of the warm pump, close the export electric door, exit the door after the door, warm pump door and pump water door).
5, turn the two main doors are always inside the leakage, resulting in the solution to the pump is very difficult to improve the system, remove the original inverted small tube, from the pump after the door, the export door in front of their own Of the warm door, bypass the inverse of the door to the inverse of the door, so improved, the inverted pump must open the door.
The purpose of the warm pump is simply to make the pump housing inside and outside the wall and the upper and lower shell temperature difference becomes small, to prevent the physical damage to the pump body, the pump is in the standby state of the pump (there are other pump operation), now the new unit Selection of the pump are basically no warm pump, which is the relationship between the material and structure of the pump, and is not related to the import.

A steam generating boiler requires that the boiler feed water should be devoid of air and other dissolved gases in order to avoid corrosion of the metal.
