Abstract

The invention discloses a water supply pump for a deaerator. The water supply pump for the deaerator comprises a pump shell which is provided with an inlet and an outlet; the pump shell is provided with a drainage valve; the pump shell is connected with the bottom of a first bearing tank and the bottom of a second bearing tank, and the first bearing tank and the second bearing tank are located onthe two sides of the pump shell separately; a spindle is arranged in the pump shell and is in key connection with an impeller, and the impeller is located in the pump shell; one end of the spindle penetrates through the pump shell to extend into the first bearing tank; the other end of the spindle penetrates through the pump shell and the second bearing tank and is provided with a pump end coupler; the pump end coupler is connected with a motor coupler through a pin; and a sealing part is arranged between the spindle and the pump shell. The water supply pump for the deaerator is simple in structure, convenient to use, convenient to operate and easy to maintain; the pressure in the pump shell can be adjusted in real time by adjusting the drainage valve, and the safety performance is high; oxygen corrosion can be effectively reduced; and the water supply efficiency is high, and good practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of water supply equipment and relates to a water supply pump for a deaerator. Background technique [0002] In the field of chemical production, the most commonly used deoxidation methods for industrial boilers include thermal deoxidation, analytical deoxygenation, vacuum deoxygenation, redox resin deoxygenation, adding Na2SO3 deoxygenation in the furnace, sponge iron powder filtration and deoxygenation, etc. , the above deaeration method has many imperfections when used in industrial boilers, especially in the field with special requirements for anaerobic water, the deaerator feed water pump is widely used, and the main function of the deaerator is to remove the oxygen in the feed water Oxygen, to ensure the quality of water supply. Oxygen dissolved in water will corrode the metal in contact with water; if gas accumulates in the heat exchanger, it will hinder the heat transfer process and reduce the heat t...
