Abstract

The invention discloses a compressor and a control method thereof, and belongs to the technical field of compressors. The compressor comprises a stop mechanism arranged on an air cylinder end cover and provided with a stop piece capable of moving telescopically relative to an exhaust valve plate, and the stop piece is used for limiting the stop position where the exhaust valve plate moves backwards when the compressor exhausts air; a controller is also included and used for obtaining operation parameters when the compressor operates, the operation parameters are one of the operation power andthe operation frequency, and the stop position of the stop piece of the stop mechanism is adjusted according to a load parameter. According to the compressor provided by the invention, the stop mechanism and the controller are additionally arranged in an existing compressor, and the stop position of the stop piece of the stop mechanism on the exhaust valve plate can be adjusted by utilizing the controller, so that the maximum retreating distance of the exhaust valve plate can be limited again; and the time for re-adjusting the exhaust valve plate to the position for closing an exhaust valve port can be shortened, so that the exhaust valve port can be quickly re-closed after the exhaust valve plate finishes exhausting.

Description

Technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and a control method thereof. Background technique [0002] Linear compressor is a relatively commonly used compressor model in the mechanical field. The components of its body generally include a casing, an oil supply device and an electromagnet assembly, etc., and specifically include motor components, cylinders, pistons, and exhaust valves. , Movers, spring support components and motors, etc.; linear compressors have the advantages of high compression efficiency and small overall volume. [0003] The exhaust valve plate in the existing linear compressor models, as the compressor load is different, the position when the exhaust valve is opened is also different, and the exhaust valve plate retreats farther under the condition of heavy load In this way, a larger-diameter exhaust passage can be formed, and when the load is small, the exhaust valve plate retreats closer...
