Description

Technical Field

[0001] This utility model relates to the field of molecular pump control technology, and in particular to a detection device for a power supply cable for molecular pump control. Background Technology

[0002] A molecular pump is a vacuum pump that uses a high-speed rotating rotor to transfer momentum to gas molecules, giving them directional velocity, thus compressing them and driving them towards the exhaust port for removal by the forestage pump. During the use of molecular pumps, sometimes an external control device is needed to control the pump, in addition to the pump controller, to achieve functions such as starting and stopping the pump, high and low speed operation, and fault alarms. This external control device is connected to the pump via a control power cable. However, molecular pumps and external control devices are usually not sold together. Therefore, when purchasing a molecular pump, it is impossible to test the external control functions of the pump controller and the proper functioning of the control power cable, making it difficult to control the external control functions. Therefore, it is necessary to provide a molecular pump control power cable testing device to solve, or at least partially solve, the above problems. Utility Model Content
