Effectively mute reciprocating pump

Abstract

The invention discloses an effectively mute reciprocating pump, and belongs to the technical field of reciprocating pumps. The effectively mute reciprocating pump comprises a base and a reciprocatingpump main body fixedly connected with the base, the base is connected with a soundproof cover which is arranged through surrounding the reciprocating pump, the inner side wall of the soundproof coveris provided with a plurality of mute units capable of absorbing sound waves in array, a box body is fixedly connected with the top of the soundproof cover, a mute system is arranged in the box body, the mute system comprises an internal sound wave monitoring module for receiving the noise in the soundproof cover, a sound wave analysis module for converting the noise into a sound pressure waveform,an anti-noise calculation module for generating an anti-noise signal, and a sound wave emitting module for outputting the anti-noise signal into the soundproof cover. The effectively mute reciprocating pump has the effects of greatly reducing the noise emitted by the reciprocating pump and realizing the mute treatment to the reciprocating pump.

Description

technical field [0001] The invention relates to the technical field of reciprocating pumps, in particular to an effectively silent reciprocating pump. Background technique [0002] At present, reciprocating pumps include piston pumps, metering pumps and diaphragm pumps, commonly known as reciprocating pumps. It is a kind of positive displacement pump, which is widely used. A reciprocating pump is a delivery machine that directly supplies energy to a liquid in the form of pressure energy through the reciprocating motion of the piston. According to the driving mode, reciprocating pumps are divided into two categories: motor pumps (electric motor drive) and direct-acting pumps (steam, gas or liquid drive). During use, the reciprocating pump will emit relatively loud noise due to its complex structure and the water hammer effect caused by the water flow movement. In the actual application process, a certain noise reduction structure will be adopted. [0003] The prior art can...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: due to the complex reasons for the noise generated by the reciprocating pump, even if the reciprocating pump undergoes the above-mentioned technical solution for noise reduction, the generated noise will still remain at a relatively high level, even if a soundproof cover is used If the fuselage cannot completely cover the reciprocating pump, there will still be gaps, which will still have a considerable impact on the surrounding environment. In some working conditions that require a quiet environment, the reciprocating pump needs to be silenced.
