But there are certain problems with regard to the lubrication of the furnace zone. For example, the satellite station or the main station is in a shutdown state due to a certain fault, so that lubricating oil entering a lubricating point at the early stage and lubricating oil temporarily stored in a pipeline are carbonized under a high-temperature environment, the carbonization lubricating oil inevitably blocks the pipeline in a reciprocating manner for a long time, so that oil-gas lubrication is disabled, and finally a bearing is damaged due to the fact that the bearing cannot be lubricated.
Therefore, when the satellite station is in the idle state, parallelly connected low pressure gas supply line 1 on high pressure gas supply line 2, and stainless steel ball valve 11 on the low pressure gas supply line 1 is in normally open state, and the air current in the low pressure gas supply line 1 constantly blows off, because be the low pressure, lubricating oil in the pipeline can not blown away, simultaneously, constantly blowing in of air current, and the cooling has avoided the carbonization of lubricating oil, and the pollution abatement.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
