Abstract

The invention provides a starting method, device and system for a magnetic levitation molecular pump and relates to the technical field of control of magnetic levitation molecular pumps. The startingmethod comprises the steps that before started, the magnetic levitation molecular pump is set to a to-be-detected state; then whether the magnetic levitation molecular pump under the to-be-detected state meets starting conditions is judged; and finally, the magnetic levitation molecular pump is controlled to be started under the circumstance that the starting conditions are met. Therefore, according to the starting method, device and system, the technical problem of a poor levitation effect can be avoided in the mode that whether the magnetic levitation molecular pump under the to-be-detectedstate meets the starting conditions is detected, and the magnetic levitation molecular pump is controlled to be started only when the starting conditions are met.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation molecular pump control, in particular to a method, device and system for starting a magnetic levitation molecular pump. Background technique [0002] The existing magnetic levitation molecular pumps are generally suspended first, and then run. Even in the case of poor suspension state, the operation of the above molecular pump can be realized by operating the control panel, but its operation state is no longer suspension operation, but It is a mechanical bearing operation, which is easy to cause the loss of the parts of the molecular pump itself. In addition, the operator who controls the magnetic levitation molecular pump is not necessarily familiar with the magnetic levitation molecular pump, so there are situations such as violent docking that may easily lead to poor suspension of the molecular pump. [0003] To sum up, the prior art has the technical problem of poor levitation eff...
