Abstract

The invention relates to the technical field of water pumps, in particular to a novel low suction pump which is characterized by comprising a pump cover, a pump body, an upper pipe outlet, a cooling lateral pipe, an impeller, a base, a mechanical sealing part, a shaft, a base rubber layer, a vacuum cavity and a vacuum sealing part. The vacuum sealing part is arranged on the periphery of the shaft, the vacuum cavity is arranged on the lower portion of the pump body, and the base rubber layer is arranged on the base and wraps the whole base. When the water pump operates, the novel low suction pump and the water surface form vacuum so that the novel low suction pump can work without water priming and operation efficiency of the water pump is improved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a novel low-suction pump. Background technique [0002] The closest similar products of the present invention are traditional vertical pipeline pumps. Traditional vertical pipeline pumps have high suction lift, low efficiency, large energy consumption, unstable operation, and cannot work without water suction. Contents of the invention [0003] In order to solve the above problems, the present invention provides a new type of low-suction pump, which is characterized in that it includes: pump cover 1, pump body 2, upper pipe outlet 3, cooling side pipe 4, impeller 5. Base 6, mechanical seal 7, shaft 8, base rubber layer 9, vacuum chamber 10, vacuum seal 11, the new type of low-suction pump has a vacuum seal 11 around the shaft 8, and a vacuum seal 11 on the lower part of the pump body 2. Vacuum cavity 10 is arranged, and base 6 is provided with base rubber layer 9, and its ...
