Abstract

The invention discloses a testing method and device of a compressor. Equivalent stiffness of a linear compressor and a linear oscillation motor can be detected accurately in real time. The method comprises the steps that a voltage sensor is utilized for collecting voltages of the compressor running at multiple moments, and a current sensor is utilized for collecting currents of the compressor running at the multiple moments; according to the voltages at the multiple moments, the voltage vector is calculated, and according to the currents at the multiple moments, a current vector is calculated; on the basis of a vector balance principle, the voltage vector and the current vector are utilized for calculating mechanical impedance of the compressor; and according to the mechanical impedance of the compressor, the equivalent stiffness of the compressor is calculated.

Description

technical field [0001] The invention relates to the technical field of compressor performance analysis, in particular to a compressor testing method and device. Background technique [0002] The further improvement of energy efficiency standards for new household appliances has made linear compressors with significant energy-saving advantages an important development direction for compressors for small household refrigeration devices such as refrigerators, air conditioners, and electronic heat dissipation. The linear compressor integrates the linear motor and the piston of the compressor, and the linear motor directly drives the piston to reciprocate, thereby compressing the refrigerant vapor. This driving method and structure makes the linear compressor save the link of converting the rotary motion to the linear motion compared with the rotary motor, and the radial force of the piston becomes small or no radial force, which reduces the power consumption of friction loss. T...
