The invention relates to measuring equipment and a measuring method for no-load torque of a reciprocating mechanical structure of a refrigeration compressor. The measuring equipment comprises two parts including a mechanical structure and a measurement and control system, wherein the measurement and control system is used for controlling the mechanical structure to work and collecting related data, and an industrial control computer in the measurement and control system is used for carrying out data processing and analysis to obtain the torque value of the reciprocating mechanical structure of the refrigeration compressor and the relation between the torque value and piston displacement and crank angle. According to the invention, the measuring equipment is adopted to measure the torque of the reciprocating mechanical structure of the piston type refrigeration compressor in no-load condition, torque corresponding to each position of the piston stroke and corresponding torque of a crank rotating by an angle can be accurately represented, and the maximal torque during reciprocating can be solved; the measuring device is simple in structure, the measuring method is simple and convenient, the measurement result is strong in intuition and high in accuracy; and by adopting the measuring device to evaluate the mechanical performances of assembly parts of the whole reciprocating mechanical structure, great effect are achieved for design and production of the piston type refrigeration compressor.
Description
technical field [0001] The invention relates to the technical field of testing equipment for refrigeration compressors, in particular to a no-load torque measuring device for a reciprocating mechanical mechanism of a refrigeration compressor. Background technique [0002] With the further development of the national economy and the gradual improvement of people's living standards, more and more occasions need to freeze, refrigerate, keep fresh, and adjust temperature, which makes the application of refrigeration equipment more extensive and its status more important. Household refrigeration equipment usually uses a piston refrigeration compressor, which is the heart of household refrigeration equipment. Its performance and quality play a decisive role in the operation of household refrigeration equipment. At present, the accuracy measurement of the reciprocating mechanism of the piston refrigeration compressor is mainly based on the measurement of a single part, and there is...
