Description

Torque measuring device of compressor

Technical Field

The utility model relates to a torque measuring device for a compressor.

Background

The compressor functions to compress a driving refrigerant in the air-conditioning refrigerant circuit. The compressor is generally installed in the outdoor unit. The compressor extracts the refrigerant from the low-pressure area, compresses the refrigerant and sends the compressed refrigerant to the high-pressure area for cooling and condensation, heat is emitted to the air through the radiating fins, the refrigerant is changed from a gas state into a liquid state, and the pressure is increased. The working circuit of the compressor divides an evaporation zone (low pressure zone) and a condensation zone (high pressure zone). The indoor unit and the outdoor unit of the air conditioner belong to a low pressure region or a high pressure region, respectively (depending on the operating state). The refrigerant flows from the high-pressure area to the low-pressure area and is sprayed into the evaporator through the capillary tube, the pressure is suddenly reduced, the liquid refrigerant immediately becomes gaseous, and a large amount of heat in the air is absorbed through the radiating fins. Thus, the compressor works continuously, and heat at one end of the low-pressure area is absorbed into the refrigerant and then is sent to the high-pressure area to be diffused into the air, so that the air temperature is regulated.

The prior art compressor generally requires a measurement of its static torque to detect a possible problem during operation of the compressor. The existing torque measurement of the compressor is generally to rotate a rotating shaft of the compressor through a wrench with a torque sensor, and determine a torque value after multiple measurements.

However, because the testing method uses different forces by operators each time, the result fluctuates greatly, and the measurement accuracy is affected.

The top of the rotating rod 42 is provided with a first transmission belt wheel 43. The first driving pulley 43 is matched with a second driving pulley (not shown in the figure). A conveyor belt 44 is matched between the first transmission belt wheel 43 and the second transmission belt wheel. The second driving pulley is fixedly connected with a driving motor (not shown in the figure), and the driving motor is fixedly connected with the mounting plate 41.

When the driving motor works, the second driving pulley rotates, and the first driving pulley 43 is driven to rotate through the conveying belt 44, so that the rotating rod 42 rotates.

The middle part of the measuring seat 11 is provided with a positioner 13 connected with the rotating rod 42. The locator 13 is provided with splines 14 which cooperate with the compressor rotating shaft to be measured. After the compressor rotating shaft tooth socket 14 is matched with the positioner 13, the rotating shaft 42 is driven to rotate when rotating, the rotating shaft rotates for a circle to sequentially pass through the sensors at each point position, a plurality of groups of torque data are measured, and the torque value of the compressor is obtained after the average value is obtained.

Optimized, the bottom of the measuring seat 11 is provided with a plurality of clamping blocks 15, and the clamping blocks 15 are abutted to the compressor, so that the position of the compressor is preliminarily fixed.
