Oil supply device and method of bearing

Abstract

The invention provides an oil supply device and a method of a bearing, wherein the device comprises a temperature sensor, a processor, a control valve, a first oil path and a second oil path, whereinthe inner diameter of the first oil path is less than that of the second oil path; the temperature sensor is used for collecting the temperature of the bearing; the processor is used for sending a first signal to the control valve when the temperature of the bearing is greater than a first temperature threshold value so as to control and conduct the first oil path; and the processor is also used for sending a second signal to the control valve when the temperature of the bearing is less than a second temperature threshold value so that the control valve can conduct the second oil path. The temperature of the bearing is collected by the temperature sensor arranged by the device, so the processor can generate the corresponding control signal according to the temperature of the bearing; and then the control signal can control the control valve to switch different oil paths so as to adjust the amount of the lubricating oil transported to the bearing; the technical problem that the amount of the lubricating oil transported to the bearing cannot be effectively, timely and rationally adjusted according to the specific operation condition of the bearing in the current method can be solved.

Description

Technical field [0001] The invention relates to the technical field of air conditioning and refrigeration, and in particular to a bearing oil supply device and method. Background technique [0002] In the field of air-conditioning and refrigeration technology, compressors are usually applied to the air-conditioning refrigerant circuit to compress and drive the refrigerant. Among them, the bearing is the main bearing and rotating component in the compressor, and its service life and reliability affect the operation and use of the air-conditioning compressor. [0003] Specifically, during operation of the compressor, the bearing temperature will increase due to friction. When the bearing temperature is too high, it will cause the bearing to fail, for example, fatigue pitting, raceway burning, jamming, etc., which will affect the normal operation of the compressor. At this time, in order to reduce the bearing temperature, lubricating oil is usually transported to the bearing, and th...
