Description
Technical field
The utility model is related to sulfur hexafluoride gas recycling field, and in particular to the compression reclaimed for sulfur hexafluoride gas
The structure of thermomechanical components is improved.
Background technology
SF6High voltage oil-free compressor is SF6Gas reclaims the nucleus equipment main frame of aerating device, with the hair of technical field
Exhibition, as China electrical circuitry equipment skill upgrading optimizes, considers from safe and reliable angle, it is traditional have oil lubricating compressor without
Method ensures pure SF completely6Gas is completely separated with oil gas, pure SF6Gas presence may be secondary polluted the general of mixing
Rate, high voltage oil-free compressor is the product of innovating technologies of power equipment industry, has fundamentally prevented have oily equipment to open electric power
The potential safety hazard of product is closed, is gradually widely used in recent years to other phases such as the production of power high voltage switch product and onsite applications
Close supporting switch accessory kit product.
Due to SF6The special working environment of high voltage oil-free compressor and requirement, inside are non lubricant oil lubrications, in SF6Reclaim
During high voltage oil-free compressor move back and forth the heat that gathers of compressed action, a part of SF can be passed through6Gas circulation takes away it
Thermal energy consumption, but especially to when reclaiming below 0 gauge pressure, the heat gathered inside compressor can not effectively circulate, and can only pass through pressure
The only fin radiating of contracting machine body surface, even if all having installed blower fan blowing cooling, blower fan in all compressor traditional senses additional
High voltage oil-free compressor section subregion can only be cooled, effect is not very obvious, blower fan blowing cooling angle is excessively concentrated, wind
Amount loss is larger, using thoroughly, energy resource consumption is not big；And compressor works long hours in high temperature environments, continue temperature rise, and it is normal
The heat abstractor of rule, which can not reach, effectively to cool, and causes temperature rise in the compressor short time big, and load increase, compressor uses the longevity
Life shortens, the high temperature heat exchange circulation on surface, and the heat inside its compressor can not still be evacuated well, and then temperature is more next
Higher, outer surface reaches as high as 90-100 degrees Celsius, now compressor internal motion part (bearing, connecting rod, piston etc.), in high temperature
Lower service behaviour declines to a great extent, and the heat that piston-ring friction is produced is gathered in cylinder body, then transfers heat to cylinder cap, connecting rod, piston body
Deng, after if things go on like this running about 500 hours, the probability about more than 75% of compressor inner part locking, even if can continue reluctantly
Work, its is both effectiveness also to decline to a great extent；
System aspects, in the case of a high temperature relevant electrical systems can to high voltage oil-free compressor carry out stoppage protection (work as
When temperature rises to certain value, SF6The temperature protection module of high voltage oil-free compressor can automatic protection compressor), but this is again
The strong influence operating efficiency of compressor, makes SF6The applicable working range of high voltage oil-free compressor reduces.Conventional SF6High pressure
The mode of oilless (oil free) compressor cooling processing does not have a wind scooper of frame structure style, compressor integrally it is exposed outside, own simultaneously
Pipeline also it is exposed outside；Under emergency case, if SF6High voltage oil-free compressor complete machine or external pipeline are by external force collision, in height
It is likely to cause generation and the SF of security incident under pressure condition6Gas is leaked.
