Problems solved by technology

The oil pumping device in the related art uses traditional centrifugal oil pump components to pump oil. The disadvantage of this oil pumping method is that when the compressor is running at a low speed, the centrifugal force of the pump oil is not large enough, causing the compressor to rotate at a low frequency. When the oil pump capacity is insufficient, the friction and motion pairs of the compressor cannot be well lubricated, which affects the reliability of the compressor

Embodiment Construction

[0033] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0034] The oil pumping device in the related art uses traditional centrifugal oil pump components to pump oil. The disadvantage of this oil pumping method is that when the compressor is running at a low speed, the centrifugal force of the pump oil is not large enough, causing the compressor to rotate at a low frequency. When the oil pump capacity is insufficient, the frictional motion pairs of the compressor cannot be lubricated well, which affects the reliability of the compressor.

[0035] Also, the compressor in the related art uses the screw principle of lubricating oil to pump oil. The oil pump system is fixedly connected with a cylindrical oil pump housing ...

Abstract

The invention discloses a compressor. The compressor comprises a housing, a motor, a crankshaft and an oil pump assembly, wherein oil liquid is stored at bottom in the housing; the motor is arranged in the housing and located above the liquid level of the oil liquid; the crankshaft is connected with the rotor of the motor, can rotate relative to the housing, and is provided with an oil path; the oil pump assembly comprises a fixed part connected with the stator of the motor and a movable part connected with the crankshaft; an oil absorption oil channel is defined between the fixed part and the movable part; one end of the oil absorption oil channel extends to the oil path; and the other end of the oil absorption oil channel extends into the oil liquid to pump the oil liquid into the oil path. According to the compressor disclosed by the embodiment of the invention, the structure is simple; the oil liquid can be pumped into the oil path of the crankshaft through the oil absorption oil channel between the fixed part and the movable part; the oil pumping capability is sufficient, and all parts of the compressor can be well lubricated, so that the normal operation of the compressor is guaranteed; the manufacturing and production cost is low; the reliability of the oil pump assembly is high; and working properties of the compressor are improved.

Description

technical field [0001] The present invention relates to the technical field of compressor equipment, and more specifically, to a compressor. Background technique [0002] In the closed frequency conversion reciprocating refrigeration compressor, during the working process, the lubricating oil at the bottom of the compressor shell is sucked into the kinematic pairs of the compressor through the crankshaft and the oil pumping device for lubrication. The oil pumping device in the related art uses traditional centrifugal oil pump components to pump oil. The disadvantage of this oil pumping method is that when the compressor is running at a low speed, the centrifugal force of the pump oil is not large enough, causing the compressor to rotate at a low frequency. When the oil pump capacity is insufficient, the frictional motion pairs of the compressor cannot be lubricated well, which affects the reliability of the compressor. Contents of the invention [0003] The present invent...
