AI Technical Summary

Problems solved by technology

Due to the characteristics of its linear motion, the running stroke of the linear compressor is easily affected by the fluctuation of the suction and exhaust pressure of the system and exceeds the set position. When the mover reaches the TDC position on the edge of the cylinder, if the power is too large or the control is wrong at this time, the mover will collide. Exhaust valve plate, high-frequency or high-impact impact / impact may easily cause the mover to fall off or the exhaust valve plate to crack, causing abnormal noise or damage to the compressor.

Abstract

The invention discloses a compressor and a method for controlling the compressor, belonging to the technical field of compressors. The compressor includes: a shell and a mover installed in the shell, one end of the mover performs linear reciprocating motion in the cylinder, and also includes: a pressure detection device, used to detect the movement of the mover in the cylinder The force produced by the movement in the cylinder. The compressor of the present invention automatically detects the force generated by the mover in the compressor on the pressure detection device to determine whether the position of the mover exceeds the set position, so as to control the movement position of the mover of the compressor and prevent the compressor from being affected by abnormal conditions. The impact of the pressure will cause the mover to hit the exhaust valve plate, protect the compressor, improve the reliability of the compressor product and prolong the service life.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and a method for controlling the compressor. Background technique [0002] The motion mode of the linear compressor placed in the refrigeration system is linear motion, which is obviously different from the traditional reciprocating compressor in structure. Due to the characteristics of its linear motion, the running stroke of the linear compressor is easily affected by the fluctuation of the suction and exhaust pressure of the system and exceeds the set position. When the mover reaches the TDC position on the edge of the cylinder, if the power is too large or the control is wrong at this time, the mover will collide. For the exhaust valve plate, high-frequency or high-impact impact / impact may easily cause the mover to fall off or the exhaust valve plate to crack, causing abnormal noise or compressor damage. Contents of the invention [0003] Embodiments of th...
