欢乐生肖网上哪里买   1.Function of deaerator: used to remove oxygen and other gases in boiler feed water to ensure the quality of feed water. At the same time, it can heat the water and raise its temperature.

  2.The role of heater installation and emptying valve: in order to prevent air from forming an air film on the surface of copper tube, increase the thermal resistance, seriously affect the heat transfer effect of heater, and thereby reduce the heat transfer efficiency, the installation and emptying valve.

  4。The purpose of setting water seal cylinder of deaerator: to ensure that the deaerator does not happen to pour water into other equipment。 Prevent deaerator overpressure。

  5.Function of heater hydrophobic device: reliably drain the hydrophobic water out of the heater and prevent the steam from leaking out.

  6。Function of deaerator water tank: store water supply, balance the difference between water supply to boiler from feed pump and water supply to deaerator from condensate pump, so as to meet the needs of water supply to boiler。

  7.Role of shaft seal heater: recover shaft seal steam leakage, used to heat condensate to reduce shaft seal steam leakage and heat loss, and improve the environmental conditions of the workshop.

  8.Effect of condensate bypass of low-pressure heater: when the heater fails or a heater is out of service, the main condensate will not be interrupted.

  9。Condensing equipment is mainly composed of condensing device, circulating water pump, steam extractor and condensing water pump。

  Task: to establish and maintain a high vacuum in steam turbine outlet。

  10.The function of condenser cooling water: condenses the exhaust steam into water and absorbs the heat released by the condensation of the exhaust steam.
