Abstract

The invention discloses a slurry pump with a leakage prevention function. The slurry pump comprises a driving motor and a pump body. A driving shaft is arranged below the driving motor. A movable shaft sealing box is connected to the lower part of a stand column pipe. O-shaped sealing rings are arranged inside the movable shaft sealing box. K-shaped sealing rings are arranged on the outer sides ofthe O-shaped sealing rings. Cooling water nozzles are arranged on the side surfaces of the O-shaped sealing rings. Connecting pipes are connected to the outer sides of the cooling water nozzles. A cooling liquid circulation device is connected to the rear ends of the connecting pipes. Connecting flanges are connected to the outer side of the movable shaft sealing box. The pump body is positionedat the lower end of the movable shaft sealing box. An impeller is arranged in the pump body. The slurry pump with the leakage prevention function is provided with the movable shaft sealing box which is convenient to disassemble and replace; the matching use of the O-shaped sealing rings and K-shaped sealing rings in the movable shaft sealing box can effectively improve the leakage prevention capability of the device; and meanwhile, the whole movable shaft sealing box can be conveniently disassembled and replaced.

Description

technical field [0001] The invention relates to the related technical field of slurry pumps, in particular to a slurry pump with leakage prevention function. Background technique [0002] Slurry pumps are similar to centrifugal pumps, and are mainly used for the transportation of liquid materials such as phosphoric acid slurry media. Shaft seal. At that time, the seal assembly was easily affected by high temperature during the operation of the slurry pump, and it was prone to wear and tear during operation, which easily caused liquid leakage. At the same time, the seal assembly of the existing slurry pump was not easy to disassemble and replace quickly, which affected the material. The long-term normal use of the slurry pump. [0003] In view of the above problems, an innovative design is carried out on the basis of the original slurry pump. Contents of the invention [0004] The purpose of the present invention is to provide a slurry pump with anti-leakage function, so ...
