Vacuum degree on-line detecting system

Abstract

The invention discloses a vacuum degree on-line detecting system which comprises a display module, a data collection terminal, a vacuum degree on-line detecting module and a vacuum on-line detecting sealing plug, wherein the vacuum on-line detecting sealing plug is used for obtaining vacuum data of vacuum equipment, the vacuum degree on-line detecting module is used for processing the vacuum data obtained by the vacuum on-line detecting sealing plug so that the vacuum degree of a vacuum layer of the vacuum equipment is obtained, and the data collecting terminal is used for obtaining vacuum degree data which is sent by at least one vacuum degree on-line detecting module and conducting alarm notification and / or outputting a signal which can control the vacuum equipment to be shut down according to a comparing result of the vacuum degree data and the preset vacuum degree parameter. The vacuum degree on-line detecting system has the advantages of achieving on-line detection of the vacuum degree of the vacuum equipment, detecting a plurality of targets, effectively playing a role in preventing safety hazard, reducing the rate of vacuum leaking and accidents of the equipment, and guaranteeing the using safety.

AI Technical Summary

Problems solved by technology

[0002] After the vacuum tube or vacuum container completes vacuuming of the vacuum interlayer through the production process, during product storage and use, the vacuum layer will be vacuumed due to the outgassing of the material itself or due to insufficient degassing during the processing process and improper installation. reduced

The reduction of the vacuum layer directly affects the heat insulation performance of the vacuum pipeline. The reduction of the heat insulation performance directly leads to the energy consumption in the vacuum pipeline. In use, the vacuum degree will not be able to last for a long time due to the problems of the material itself or the processing technology and installation technology. Storage, the degree of vacuum will gradually decrease. If the degree of vacuum drops to a certain level, the heat insulation effect will be lost, resulting in leakage, which will cause unnecessary consumption of energy and bring safety hazards

[0003] At present, the vacuum tube or vacuum container cannot detect the change of the vacuum degree of the vacuum layer on-line during use, as well as the early warning and alarm of the vacuum degree of the vacuum layer, etc.

The vacuum degree of the vacuum layer can only be judged by visual observation experience, or whether the current vacuum degree of the vacuum layer has dropped through natural phenomena such as whether the surface of the pipeline or the storage tank is frosted and water hangs, and the vacuum degree of the vacuum layer cannot be accurately obtained. value
