Mechanical pump provided with noise reduction structure

Abstract

The invention discloses a mechanical pump provided with a noise reduction structure. The mechanical pump comprises a mechanical pump body; the top of the mechanical pump body is fixedly connected witha motor; the surface of the motor is sleeved with a supporting plate; and the bottom of the supporting plate is fixedly connected to the top of the mechanical pump body. According to the mechanical pump, the bottom of a protection box is inserted in a containing groove, then the protection box is fixed through a limiting mechanism, the mechanical pump body is started, the sound energy of noise generated by the mechanical pump is converted into heat energy through foam metal, and the heat energy converted by the foam metal is removed through heat dissipation holes formed in the surface of theprotection box finally, so that the mechanical pump has the advantage that noise reduction can be performed on the motor at the top of the mechanical pump, and the problems that most existing mechanical pumps are too high in noise during operation, injure human bodies easily and affect the surrounding environments due to the fact that the mechanical pumps do not have the function of reducing noiseof motors at the tops of the mechanical pumps are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical pumps, in particular to a mechanical pump with a noise reduction structure. Background technique [0002] Mechanical pump, that is, mechanical vacuum pump, is a kind of machine for making vacuum. It can discharge or absorb air in a closed or semi-closed space to achieve a relative vacuum in the local space. Common vacuum pumps include reciprocating vacuum pumps and water ring pumps. , Molecular pumps, rotary vane vacuum pumps, piston vacuum pumps, swinging piston vacuum pumps, diaphragm vacuum pumps, linear vacuum pumps, etc. There are many types. [0003] Mechanical pumps are used to create vacuum, but most of the existing mechanical pumps do not have the function of reducing the noise of the motor on the top of the mechanical pump, which leads to excessive noise during the operation of the mechanical pump and may cause damage to the human body. It will affect the surrounding environment and ...
