Internal circulating multi-stage centrifugal water pump

Abstract

The invention relates to the technical field of centrifugal water pumps, in particular to an internal circulating multi-stage centrifugal water pump. The internal circulating multi-stage centrifugal water pump includes a water pump body, a base, two mounting grooves, two fixed rods, two sliders and two first springs, wherein the base is arranged below the water pump body; the two mounting grooves are both formed in the top of the base; the two fixed rods are fixedly installed on the inner walls of the two mounting grooves, respectively; the two sliders are respectively slidably sleeve the two fixed rods, respectively; the two fixed rods are sleeved with the two first springs correspondingly; one end of each of the two first springs is fixedly connected with the inner wall of the corresponding mounting groove; and the other end of each of the two first springs is fixedly connected with the outer wall of the corresponding slider. The internal circulating multistage centrifugal water pump provided by the invention has the advantages of being simple to operate, convenient to maintain in later period and capable of being stably placed at an uneven position, and saving a certain time.

Description

technical field [0001] The invention relates to the technical field of centrifugal water pumps, in particular to an internal circulation multistage centrifugal water pump. Background technique [0002] A multistage centrifugal pump is a collection of two or more centrifugal pumps with the same function. In terms of the fluid channel structure, the medium pressure relief port of the first stage communicates with the inlet of the second stage, and the medium discharge port of the second stage communicates with the inlet of the second stage. The pressure port communicates with the inlet of the third stage, and the mechanism in series in this way forms a multistage centrifugal pump. [0003] However, most of the multi-stage centrifugal water pumps are fixed on the mounting plate by multiple bolts, and they need to be disassembled during later maintenance and position movement. During the disassembly process, a lot of time is wasted. Increase the man-hours of disassembly. Most o...

Problems solved by technology

[0003] However, most of the multi-stage centrifugal water pumps are fixed on the mounting plate by multiple bolts, and they need to be disassembled during later maintenance and position movement. During the disassembly process, a lot of time is wasted. Increase the man-hours of disassembly. Most of the multi-stage centrifugal water pumps are usually installed outdoors, and often encounter uneven ground. When the multi-stage centrifugal water pumps need to be placed in parallel, they need to be placed in a flat position or a suitable height block is required. As a result, it is more troublesome to place the multistage centrifugal water pump. If the multistage centrifugal water pump is not placed stably, it will dump during operation and damage the multistage centrifugal water pump.
