Description

Technical Field

[0001] The utility model relates to the technical field of heat pump production, in particular to a clamping mechanism for production and detection of air energy heat pump accessories. Background Art

[0002] A heat pump is a highly efficient energy-saving device that utilizes low-grade thermal energy. Its working principle is to force heat from a low-temperature object to a high-temperature object through a reverse cycle. During the operation of the heat pump, it consumes only a small amount of reverse cycle net work to obtain a large amount of heat supply, thereby effectively utilizing the difficult-to-use low-grade thermal energy and achieving the purpose of energy saving.

[0003] For example, a test device for the performance of a ground source heat pump unit with publication number CN214471787U uses a cylinder to drive a clamping plate to move, clamp the hose, and clamp the hose to close one end. In conjunction with a related detection mechanism, the air tightness of the hose can be automatically tested, reducing the burden on the operator. However, when the clamping plate is used to clamp the hose to close it, large creases will be produced on the top and bottom of the hose, and there is a high probability that there will be gaps at the top and bottom, affecting the test results. For this reason, a clamping mechanism for production and testing of air energy heat pump accessories is proposed for improvement. Utility Model Content
