Fuel injection helical lobe compressor lubricant oil ancillary equipment

Abstract

The present invention discloses an oil-injected screw compressor lubricant-adding equipment for adding lubricant to an oil-injected screw compressor, which can realize online lubricant adding. The equipment comprises a screw compressor and an oil-gas separator communicated by tubes, an oil storage cylinder is arranged in parallel on the tubes between the screw compressor and the oil-gas separator. The air inlet end of the oil storage cylinder is connected with the tubes between the screw compressor and the oil-gas separator and the outlet end of the oil storage cylinder is communicated with the oil-gas separator. Because the oil storage cylinder is arranged on the tubes between the screw compressor and the oil-gas separator, lubricating oil is added into the oil storage cylinder to complement lubricating oil to the screw compressor while the screw compressor is working. The equipment can ensure the quality of lubricating oil during recycling use, prolomg the service life of lubricating oil, reduce lubricating oil consumption by 40 to 60 percent and increase the continuous working time of the screw compressor. The equipment is especially suitable to be popularized on oil-injected screw compressors.

Description

technical field [0001] The invention relates to a device for replenishing lubricating oil, in particular to an oil-spraying screw compressor lubricating oil replenishing device for replenishing lubricating oil for an oil-spraying screw compressor. Background technique [0002] At present, there are more than 100 oil-injected screw compressor manufacturers in the country. [0003] When adding lubricating oil to the oil-injected screw compressor, due to the structural limitation of the screw compressor, only the process of stopping the oil to add lubricating oil can be used. The process has the following problems: [0004] a. The oil replenishment time interval of the shutdown replenishment lubricating oil process is long. In order to maintain the lubricating oil consumed in long-term normal operation, the amount of lubricating oil replenished each time is relatively large, resulting in a large amount of lubricating oil recycled in the compression process. With the extension...

AI Technical Summary

Problems solved by technology

When the screw compressor is shut down for a long time, there is no pressure difference between the suction and exhaust of the compressor to maintain the circulation of lubricating oil. To lubricate the rotor of the compressor and seal the gas in the compression chamber when the machine is restarted, the screw compressor must first be replenished with lubricating oil, and at this time, the suction pipe of the screw compressor must be removed to replenish the lubricating oil for the screw compressor cumbersome operation
