Abstract

The invention provides a miniature mute pump and an operating method thereof. The mute pump comprises a base, an O-shaped magnet, a rectangular wireframe made of a non-magnetic-conductive material, a connecting rod and a piston pump. The O-shaped magnet is fixed to the base and is formed in the manner that the same magnetic poles of two identical U-shaped magnets cling together into an O shape. One side of the rectangular wireframe penetrates through the O-shaped magnet. One end of the connecting rod is connected with the midpoint of the opposite side of one side of the rectangular wireframe. The other end of the connecting rod penetrates through a guide rail and is connected with a piston of the piston pump. The guide rail is fixedly mounted on the base through a support. An N-turn rectangular hollow coil is wound around the rectangular wireframe, and N is a positive integer. The two ends of the coil are connected with the two output ends of a sine AC power supply. The formula of the sine AC power supply is shown as follows: u=U<m>*sin(omegat+a<0>), wherein omega is the angular frequency and is equal to 2pif which is less than 20Hz, f is the frequency of sine AC, U<m> is the maximum voltage value, and a<0> is an initial phase. The miniature mute pump can be really mute and is simple in structure.

Description

technical field [0001] The invention belongs to the field of fluid medium transportation, and in particular relates to a miniature silent pump and a working method thereof. Background technique [0002] In the prior art, there are many pumps for conveying fluid media, such as piston pumps, centrifugal pumps, and diaphragm pumps. The piston pump uses the reciprocating motion of the piston in the cylinder to cooperate with the one-way valve to realize the delivery of fluid medium. The centrifugal pump realizes the fluid medium transportation through the centrifugal force generated by the pump blades rotating at high speed. Similar to the piston pump, the diaphragm pump relies on mechanical force to change the volume of the diaphragm, and cooperates with the one-way valve to realize the delivery of fluid medium. [0003] In some occasions, it is necessary to transport fluid almost without noise. This kind of equipment is called a silent pump. The noise index of silent pumps ...
