Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of materials consumption that can reduce compressor pump significantly, the pump body structure of the refrigeration compressor of the structure stability in the time of guaranteeing the compressor installation and operation again.
For solving the problems of the technologies described above, the pump body structure of the utility model refrigeration compressor comprises bent axle, connecting rod, crankcase, piston, valve group, stator and rotor, be provided with two stator installation feet in the described crankcase, the position of one of them described stator installation foot is near the cylinder end face, and the position of another described stator installation foot is away from the cylinder end face; With the stator installation foot position of described crankcase accordingly, described stator is provided with two stator mounting holes, described stator is fixed on the described crankcase by bolt and described stator mounting hole.
The pump body structure of above-mentioned refrigeration compressor, it also includes three supported springs, described three supported springs are triangularly arranged, one of them described supported spring is located at the below away from the described stator installation foot of cylinder end face, and two other supported spring is located at the both sides near the below of the described stator installation foot of cylinder end face respectively.
The pump body structure of above-mentioned refrigeration compressor, described one or two stator installation foot is provided with the end face groove.
The utility model has been owing to adopted technique scheme, and crankshaft hole is in or very near the neutral position of two stator installation feet, crankcase structure is reliable and stable in the structure.The crankcase structure of two stator installation feet of employing can obviously reduce the volume and weight of pump body structure, can reduce the materials consumption of compressor pump significantly.Adopt the spring supporting way of triangular arrangement in the structure, can fully guarantee the reliability and stability of compressor when assembling and operation.On one or two stator installation foot the end face groove is set, can forms the stator attachment face more than three on two stator installation feet, the distortion that produces when stator installation and compressor operating is very little, thereby can not influence the reliability and stability of compressor.
