Problems solved by technology

[0003] Existing axial flow pumps avoid clogging by cutting impurities in the water, but the cutting blade is easily entangled by aquatic plants or some domestic garbage, and then jammed. Some axial flow pumps will have filters installed inside them. However, since the water flow is always pumped upward, the impurities under the filter will increase and cannot be discharged, which will reduce the pumping efficiency. Therefore, we propose an axial flow pump with anti-clogging function to solve the above problems. mentioned problem

Abstract

The invention belongs to the field of axial-flow pumps, particularly relates to an axial-flow pump with an anti-blocking function, and provides the following scheme to solve the problems that existing axial-flow pumps are prone to jamming, part of the axial-flow pumps are internally provided with filter screens, but impurities under the filter screens are more and more and cannot be discharged, and then the water pumping efficiency is reduced. The axial-flow pump comprises a pump body and a connecting pipe, the connecting pipe is located below the pump body, connecting assemblies used for connection are arranged at the connecting pipe and the water inlet end of the pump body, a water inlet is formed in the bottom of the connecting pipe, and a water outlet is formed in one side of the pump body. According to the axial-flow pump, the water suction process is realized through an impeller; through arrangement of a first filter screen and a second filter screen, the filtering quality can be improved, and the pump is prevented from being blocked; through arrangement of an ash discharging port, impurities below the second filter screen can be continuously discharged, and the pump is prevented from being blocked; a guide vane can eliminate the rotating motion of water flow, and the water pumping efficiency is improved.

Description

Technical field [0001] Technical Field The present invention relates to an axial pump, in particular, it relates to axial flow pump having an anti-jam function. Background technique [0002] By the rotating impeller blades axial flow pump to force the liquid produced by the pump conveying the liquid along the axial direction, vertical, horizontal, inclined and crossflow several. Since 1961, China has developed a total of 664 sets of large axial flow pump. Ratio of number of revolutions n which are 500,700,850,1000,1250,1400,1600 like; runner diameter of 1.6m, 2.0m, 2.8m, 3.0m, 3.1m, 4.0m and 4.5m. In Jiangsu, Hubei, Hunan, Anhui, Guangdong, Tianjin, Shandong, Shanxi, Shaanxi, Xinjiang and other 16 provinces, municipalities and autonomous regions to build a large axial flow pump station a total of 114, with a total installed capacity of 630,000 kW. [0003] By cutting the conventional axial flow pumps are impurities in the water, thereby avoiding clogging, but the cutting blade ca...
