Application of synthetic lubricating oil in processing and hydrocarbon presses

Synthetic lubricants are used in positive displacement devices, lubricant processing and hydrocarbon gas compressors are controversial. Many of these applications require synthetic products to limit toxic catalysts, reduce gas solubility and thereby lead to loss of viscosity and limit reactions with gases.

The difference between air-cooled and water-cooled screw air compressors

The difference between air-cooled screw machine and water-cooled screw machine: 　　The oil cooler of the air-cooled screw compressor and the compressed air after-cooler are made into one body. It is an aluminum plate-fin structure and brazed in a vacuum furnace. Once the oil leaks, it is almost irreparable and only replaced. The working principle is that hot oil and high temperature (about 80℃) gas flow in their respective pipes,
