Diaphragm compressor driven by linear motor

Abstract

The invention discloses a diaphragm compressor driven by a linear motor. The diaphragm compressor driven by the linear motor comprises an outer shell, a compressing component and a cylinder body component, wherein the compressing component is contained in the outer shell and is fixed on the outer shell through a main support, the cylinder body component is communicated with the compressing component to achieve gas compression, and the compressing component is driven by the linear motor which is fixed on the main support and is arranged around the compressing component. According to the diaphragm compressor driven by the linear motor, due to the facts that diaphragm compressor is directly driven by the linear motor, and middle energy conversion mechanisms such as a crank connecting rod are omitted, the diaphragm compressor is compact in structure, and the size and the weight of the diaphragm compressor are greatly reduced. Mechanical wear is reduced, and operation efficiency is improved. Meanwhile, control over a piston stroke can be achieved through adjustment of the amplitude of current, and therefore the diaphragm compressor driven by the linear motor can adapt to real-time changes of working conditions, and can reduce energy consumption.

Description

technical field [0001] The invention relates to compressor equipment, in particular to a diaphragm compressor driven by a linear motor. Background technique [0002] Diaphragm compressor is a special volumetric compressor that compresses gas by changing the volume of the air cavity through the deformation of the diaphragm. A curved surface is processed on the cylinder head and the oil distribution plate of the diaphragm machine die head, and a diaphragm is sandwiched between the curved surfaces. The diaphragm separates the die head into an air cavity and an oil cavity, and the air cavity and the valve hole of the cylinder head are installed. The suction and exhaust valves in the die are connected, while the oil chamber is connected with the oil chamber in the cylinder body through numerous diversion holes on the oil distribution plate. The bolts around the die head connect the cylinder head, diaphragm, oil distribution plate and cylinder body. Fastened together so that both...

Problems solved by technology

It achieves gas compression through a rotating motor and a crank-slider mechanism, but its structure is still relatively complicated, with many parts and a large body, which cannot be fully applied to applications with small displacement.
