Abstract

The vacuumizing control device provided by the invention comprises a control module and a driving module. The control module is used for receiving the current vacuum degree value of a target vacuumizing chamber and generating a logic control signal according to the current vacuum degree value and a preset vacuum degree threshold value. The input end of the driving module is connected with the control module, and the output end of the driving module is connected with a vacuum pump for receiving the logic control signal and generating a driving signal according to the logic control signal so as to drive the vacuum pump to vacuumize. Through the implementation of the invention, when the current vacuum degree value is not within the preset vacuum degree threshold range, the vacuum pump is driven to vacuumize, and when the current vacuum degree value is within the preset vacuum degree threshold range, the vacuum pump is stopped from vacuumizing, so that the continuous operation time of the empty pump is shortened, and the service life of equipment parts is prolonged.

Description

technical field [0001] The invention relates to the field of vacuum control, in particular to a vacuum control device. Background technique [0002] Both atomic emission spectrometry and atomic emission spectrometer quantitative analysis require an optical path spectroscopic imaging system to perform spectroscopic and full-spectrum data collection on the excitation light source. In order to eliminate the external interference brought by external light, air and mechanical deformation to the optical path spectroscopic imaging system, the optical chamber in the optical path spectroscopic imaging system needs to be in a sealed constant temperature vacuum state. Specifically, on the one hand, changes in the temperature and vacuum inside the optical chamber will cause the intensity of the excitation light source in the optical chamber to be unstable, and the longer the wavelength of the analytical light, the better the air absorption effect, resulting in a decrease in the intensit...
