Embodiment Construction

[0011] Such as Figure 1 ~ Figure 2 As shown, there is an air vent on the ventilation side 2a of the cooling liquid chamber, and the cooling fan blade 4 is installed in the cooling liquid chamber 2, and the cooling fan blade 4 is fixed on the drive shaft 11 by the transmission connection fastener 3 and rotates accordingly. , under the action of the centrifugal force of the rotating cooling fan 4, the cooling fan 4 generates a gas flow in the ventilation side 2a of the cooling liquid chamber. Through the side plane 2b, the heat generated in the cooling liquid chamber 12 due to the friction of the double-end mechanical seal is discharged, thereby effectively controlling the temperature in the cooling liquid chamber 12 .

[0012] In addition, an air deflector 13 is installed near the side plane 2b of the cooling liquid chamber 2. The outlet direction of the air deflector 13 is close to the side of the cooling liquid chamber 12. The air deflector 13 can increase the range of gas f...

Abstract

The invention relates to a centrifugal pump of a cooling wind leaf, which is coaxially arranged on a pump and a driver device, and the centrifugal pump is characterized in that the cooling leaf fixed on a driving shaft is additionally arranged in a cooling liquid chamber and is driven by the rotating driving shaft, the cooling wind leaf causes air to flow under the centrifugal force, so heat in the cooling liquid cavity is released with the air flow for effectively controlling the temperature in the cooling liquid cavity.

Description

[0001] The invention relates to a centrifugal pump with a coaxial pump and a driving device, in particular to a centrifugal pump for transporting high-temperature liquid. Background technique [0002] Existing dry-installed WL vertical centrifugal pumps with features such as image 3 Cooling unit in the configuration shown. [0003] Such as image 3 As shown, the WL vertical centrifugal pump is equipped with a cooling liquid chamber 2 between the driving device 1 and the pump body 6, and the fluid in the cooling liquid chamber 7 dissipates heat through the outer surface of the cooling liquid chamber 2, but when transporting high-temperature liquid, The temperature of the cooling liquid cavity 7 is relatively high, which easily leads to failure of the mechanical seal. Contents of the invention [0004] The object of the present invention is to provide a cooling device that can effectively dissipate heat between the cooling liquid chamber and the driving equipment, that is, th...
