Mute intelligent multistage pump

Abstract

The invention discloses a mute intelligent multistage pump. The mute intelligent multistage pump comprises a multistage pump main body, wherein a top end pump column is fixedly arranged in the middleposition of the lower end surface of the multistage pump main body, a mute column is arranged on the lower end surface of the top end pump column, and a ring thread groove is formed in the position, close to the middle, of the lower end surface of the top end pump column; and a threaded pipe is arranged in the middle position of the upper end of the mute column, a plurality of sets of gap groovesare evenly formed in the outer surface of the mute column, and a filter screen cover is arranged in the middle position of the interior of the mute column. According to the multistage pump, noise canbe wrapped and surrounded all around, and the noise is decomposed into a plurality of groups through sound absorption gaps in the surface of the filter screen cover to be absorbed into the gaps correspondingly, so that the generated concentrated noise is effectively absorbed and consumed in a graded mode, and a mute operation function of the multistage pump is achieved; and a mute structure part of the multistage pump can be disassembled, inspected and maintained in real time, and maintenance personnel can conveniently flush and clean the mute structure part, so that the phenomenon of noise rebound caused by high local noise is avoided.

Description

technical field [0001] The invention relates to the field of intelligent multistage pumps, in particular to a silent type intelligent multistage pump. Background technique [0002] The multi-stage pump is a kind of centrifugal pump that is combined with the water inlet and outlet section and the middle section through a tie rod. Its output water pressure can be very high, and it relies on the rotation of the impeller to obtain centrifugal force. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, thereby gradually obtaining a high vacuum. With the continuous development of society, the structure and function of the multi-stage pump have been improved accordingly, but the existing multi-stage pump still has certain problems. Insufficient, the disassembly inspection and maintenance of the multi-stage pump is more inconvenient, I believe that it will be further improved in the future to meet the different needs of use; [0003] Most ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a silent intelligent multi-stage pump to solve the problem that most of the multi-stage pumps on the market proposed in the above-mentioned background technology cannot realize all-round wrapping and absorbing of noise, cannot decompose and absorb noise, and do not have quietness. The function of operation makes it inconvenient to disassemble, inspect and maintain the multi-stage pump, and it is not convenient for maintenance personnel to clean up some components, which may easily cause the problem of noise rebound
