Magnetic transmission piston-type valveless compressor

Abstract

The invention relates to a magnetic transmission piston-type valveless compressor, which comprises a motor case. The two ends of the motor case are respectively connected with a cylinder head and a rear cover. A cylinder liner is arranged in the cylinder head. The compressor additionally comprises a crankshaft. A motor rotor is coaxially arranged at one end of the crankshaft. A magnetic rotor is coaxially arranged at the other end of the crankshaft. A magnetic piston which is matched with the magnetic rotor is additionally arranged in the cylinder liner. The magnetic rotor and the magnetic piston form an attraction or repulsion state under the rotating acting force of the crankshaft to enable the magnetic piston to be in a continuous reciprocating motion state. An exhaust passage which is communicated with the cylinder head and the magnetic piston is additionally arranged between the cylinder head and the magnetic piston. According to the technical scheme, by driving the magnetic piston to move circumferentially through the crankshaft and by using the principle of homopolar repulsion and heteropolar attraction, the continuous reciprocating motion of the magnetic piston in a cylinder is realized, the process of compressing air is completed and the compressed air is exhausted out of the compressor through the exhaust passage.

Description

technical field [0001] The invention relates to a compressor, in particular to a magnetic drive piston type valveless compressor. Background technique [0002] At present, the compressors used in the refrigeration and air-conditioning industry mainly include piston type, screw type, rotary type, centrifugal type and scroll type. Among them, the piston compressor is the earliest compressor designed, manufactured and applied. It is also the compressor with the widest application range and the most mature manufacturing process. It is the most widely used type in small and medium-sized commercial refrigeration systems. However, due to the design principle of the original structure of the piston compressor, there are still many problems and shortcomings: for example, there are too many moving parts, the structure is complicated, the maintenance workload is large, and the maintenance cost is high; the force is unbalanced, and there is no way to control the reciprocation Inertial ...

Problems solved by technology

However, due to the design principle of the original structure of the piston compressor, there are still many problems and shortcomings: for example, there are too many moving parts, the structure is complicated, the maintenance workload is large, and the maintenance cost is high; the force is unbalanced, and there is no way to control the reciprocation Inertial force; wear of the piston ring, wear of the cylinder, and the transmission mode of the belt make the efficiency drop rapidly; the noise and vibration are relatively large; due to the reciprocating motion, the compressed air is not discharged continuously and has pulsation, etc.
