Opposed permanent magnet electromagnetic air pump

Abstract

The invention relates to an opposed permanent magnet electromagnetic air pump, which includes a motor and an air pump arranged at the end of the motor; the motor includes a casing and a magnet assembly arranged in the casing, the magnet assembly is connected with the air pump through a tappet, and is located at the end of the casing. A baffle is arranged longitudinally in the central position, and the baffle divides the pump body into two symmetrical parts; a slide rail composed of multiple guide rails is fixed concentrically across the casing, and a magnet assembly is arranged on the slide rail; the magnet assembly is two Two, they are symmetrically arranged on both sides of the partition in the casing; there are two tappets, they are respectively fixed on the outer ends of the two magnet assemblies, and fixed on the air pump through the casing; there are two air pumps, they are Symmetrically attached to both ends of the motor. The invention has low noise, low vibration, medium pressure, simple and reliable structure, can run stably for a long time, and is especially suitable for providing air power for an air purifier.

Description

technical field [0001] The invention relates to the technical field of gas compression and gas delivery equipment, in particular to an opposed permanent magnet electromagnetic gas pump. Background technique [0002] In recent years, more and more gas filtration, gas compression and gas cleaning devices are widely used in life and production. [0003] There are mainly three types of air conveying equipment in the market: rotary vane fan air pump, piston air compressor air pump and rotary vane air pump. The disadvantage of the rotary vane fan is that the wind pressure is small, the noise is large when the wind resistance increases, and the efficiency becomes low. It is not suitable for high-precision air filtration equipment with large resistance and long pipeline air supply equipment. The advantages of piston and rotary vane air compressors are high pressure; the disadvantages are complex structure, small displacement, high noise, high manufacturing cost, secondary oil pollu...

AI Technical Summary

Problems solved by technology

The disadvantage of the rotary vane fan is that the wind pressure is small, the noise is large when the wind resistance increases, and the efficiency becomes low. It is not suitable for high-precision air filtration equipment with large resistance and long pipeline air supply equipment.

The advantages of piston and rotary vane air compressors are high pressure; the disadvantages are complex structure, small displacement, high noise, high manufacturing cost, secondary oil pollution, high operating cost, and are not suitable for air purification equipment and medium pressure air supply equipment

Small and medium-sized air pumps mostly use electromagnetic drive. When the moving magnet starts and stops, due to the energy storage and discharge of the wire pack of the electromagnet, its voltage is high and the current is large, which brings great vibration and noise to the air pump.
