Description

technical field

[0001] The invention relates to a double-suction pump, in particular to a leak-free high-efficiency double-suction pump. Background technique

[0002] Both the driving end and the non-driving end of the traditional double-suction pump use rolling bearings, and the two ends of the pump must use sealing components. The structure is complicated, the manufacturing cost of the water pump is high, there are many fault points in the operation of the water pump, and maintenance is difficult. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a leakage-free and high-efficiency double-suction pump with strong bearing capacity, stable operation and no leakage.

[0004] In order to solve the above technical problems, the leak-free high-efficiency double-suction pump provided by the present invention includes a pump body, a pump cover and a rotor component. The driving end of the rotor component is provided with...

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] see figure 1 , the driving end of the rotor part 4 is provided with a sealing part 7 and a bearing part 8, a sleeve bearing 3 is provided between the non-driving end of the rotor part 4 and the pump body 1 and the pump cover 5, and the non-driving end of the rotor part 4 adopts the end The cover 2 is statically sealed with the pump body 1 and the pump cover 5. One branch of the flushing water pipe part 6 arranged on the pump cover 5 communicates with the sealing part 7, and the other branch is connected between the end cover 2 and the sleeve bearing 3.

[0012] see figure 1 , the pump body 1 and the pump cover 5 constitute the flow channel of the water pump, the impeller of the rotor part 4 is aligned with the flow channel, the non-driving end is supported by the sleeve bearing 3, and the sleeve bearing 3 bears the radial force of the r...
