Adjustable-height anti-blocking vertical long shaft pump

Abstract

The invention discloses an adjustable-height anti-blocking vertical long shaft pump. The pump comprises a rectangular fixing plate. An automatic lifting mechanism is arranged at the lower end of the rectangular fixing plate. A sliding anti-blocking mechanism is arranged at the lower end of the automatic lifting mechanism. A circulating water cooling mechanism is arranged on one side of the automatic lifting mechanism. The adjustable-height anti-blocking vertical long shaft pump has the beneficial effects that the long shaft pump can vary as the liquid level varies through adjusting of the automatic lifting mechanism, it is guaranteed that a water inlet pipe is always under the liquid level, idling of the long shaft pump is avoided, an anti-blocking hood can be cleaned in real time under the effect of the sliding anti-blocking mechanism, and therefore, the blocking probability is lowered.

Description

technical field [0001] The invention relates to the technical field of long-axis pump applications, and more specifically, relates to a height-adjustable anti-blocking vertical long-axis pump. Background technique [0002] The existing vertical long-axis pumps are often used to transport clean water, rainwater, scale water, sewage, corrosive industrial wastewater, seawater and other liquids that do not contain particles and fibers, and are widely used in water companies and sewage treatment plants , and other industrial and mining enterprises, as well as municipal water supply and drainage, flood control and drainage projects. This kind of pump sucks water from the axial end of the water inlet bell mouth below, passes through the impeller and the space guide vane body behind it, and then axially flows into the inner and outer cylinders, and then flows out through the outlet elbow. [0003] In actual use, the height of the suction port of the long-axis pump is generally clos...

AI Technical Summary

Problems solved by technology

[0003] In actual use, the height of the suction port of the long-axis pump is generally close to the liquid surface, so as to prevent the inhalation of a large amount of sediment. The suction liquid level through the long-axis pump will change to a certain extent. Due to the height of the suction port, idling will occur, which will cause damage to the main body of the long-axis pump. Due to the factors of the working environment, the suction port of the long-axis pump will be installed with a filter, but when the liquid contains a lot of sediment, it is very easy to Blockage occurs, which affects the normal operation of the long shaft pump
