Abstract

The invention discloses a method and system for tracking axial force of a scroll machine. The method includes the following steps: setting an electromagnetic probe in the scroll machine to obtain electromagnetic force parameters of the scroll machine; establishing an "original theory of electromagnetic force" "Target curve", and take the "original theoretical target curve" as the target to perform electromagnetic force tracking control; obtain the exhaust flow of the scroll machine and the current of the spindle motor when tracking the "original theoretical target curve"; According to the initial magnitude of the electromagnetic force in the compartment, record the exhaust flow and the current of the spindle motor, and analyze the change rule of the feedback exhaust flow and the current signal of the spindle motor; Modify the target value of electromagnetic force in each zone, and generate a new "target electromagnetic force curve" that is the most suitable. In the method, the "original theoretical target curve" of the axial electromagnetic force of the scroll machine under preset working conditions is corrected and optimized according to the feedback signal.

Description

technical field [0001] The invention relates to the technical field of scroll machines, in particular to a method and system for tracking axial force of a scroll machine. Background technique [0002] Scroll compressor is a new type of positive displacement compressor. The compression part is composed of movable scroll and stationary scroll. It has the advantages of simple structure, few wearing parts, small volume, high reliability, high mechanical efficiency and low noise. and other excellent thermodynamic and mechanical properties. The structure of the compression chamber of the scroll compressor is composed of a moving and static scroll. The working diagram of the moving and static scroll is as follows figure 1 . During the working process, the stationary scroll is fixed on the frame, the moving disk is driven by the eccentric shaft and controlled by the anti-rotation mechanism, and rotates in a plane with a small radius around the center of the base circle of the stat...
