Description

Portable bearing pedestal tightness detection device

Technical Field

The utility model relates to the technical field of bearing detection equipment, in particular to a portable bearing seat tightness detection device.

Background

The scroll compressor has the main flow structure of the electric compressor due to the simple structure, light weight, few parts, high reliability, stable operation and low noise. In order to reduce the manufacturing cost, the stable operation of the pump body can be ensured through the dynamic balance of the movable disc. In the running process of the compressor, axial gas thrust is generated due to continuous compression of gas, the movable disc tends to be far away from the static disc, internal leakage is increased, the product performance is reduced, and even the compression function is lost due to serious internal leakage. The pressure of the back pressure cavity is used for balancing the axial gas thrust in design, so that the movable disc is tightly attached to the static disc, internal leakage is reduced, and stable operation of the pump body is ensured.

In the use process, the conditions of unstable pressure building, low refrigerating capacity and the like can happen occasionally, the disassembling machine is convenient for observing and detecting the abrasion condition of each part, and the failure reason is analyzed. However, since the bearing seat assembly is a press-fitted component, the assembled state of the component cannot be reproduced after disassembly, and if the assembly relationship is complicated, the state of the component cannot be judged, which is not beneficial to searching and judging the failure cause, there is a need for a device for judging the state of the bearing seat assembly in a non-disassembled state and observing whether leakage and abnormal wear exist.
