"The blending system of the lubricating oil production line mainly includes: base oil storage tank, different additive storage tanks, feed pump conveying pipeline, blending tank, steam boiler, process control system, filling machine, inspection and testing system, filters and other equipment. The base oil and additives are blended in the blending tank for process blending, and different oil products are produced according to the different base oils and additives.

The main process of lubricating oil blending equipment is blending, and the metering process of additives. The metering process design includes weight control, and of course, there are some control devices here, including weighing modules, instruments, and terminal PLC systems. Of course, there is also a matching air compressor in a system, which is used to control the opening and closing of the pneumatic valve body and cooperate with the completion of the metering process.
