What are the components of a High pressure Oxygen Compressors?

We often see a complete high-pressure oxygen compressor, but to understand the internal structure of the high-pressure oxygen compressor in order to better use and maintenance of it, the following will be detailed introduction of the internal structure of the high-pressure oxygen compressor and its work flow.

High pressure oxygen compressor structure

The high-pressure oxygen compressor unit is mainly composed of compressor host, driver, interstage cooler, compressed air separation, purification and other treatment devices, as well as pressure display, control and safety devices. The main compressor is of three-stage compression and V-type structure, which consists of crankcase, crankshaft, connecting rod, piston, cylinder and air valve and other basic parts. The crankcase is made of aluminum alloy; The crankshaft is a single bend structure; Connecting rod system integral body; The piston structure is of class difference type, in which the first and second class are integral type, and the first and third classes are combined type. Piston rings are installed on the first and second stage pistons, and no piston rings are installed on the third stage pistons. Labyrinth groove is used to seal between the piston and cylinder. 1, 2 and 1, 3 cylinders are integral, using high quality cast iron casting, casting radiators outside, air valve ring valve structure. The main compressor is driven by an electric motor through a triangular belt. A large air volume cooling fan is installed on the belt wheel of the main compressor, and forced cooling is carried out on the appearance and heating parts of the compressor. The compressor USES splash lubrication, with the help of the oil needle mounted on the big end of the connecting rod, when the crankshaft rotates, it stimulates the oil droplets and oil mist caused by the oil surface in the crankcase, so that the friction parts are fully lubricated.

Work flow of high pressure oxygen compressor

The high-pressure oxygen compressor unit is mainly composed of the main compressor, the driving machine (motor), the interstage cooler, the processing devices such as compressed air separation and purification, as well as the pressure display, control and safety devices. When the driving machine drives the compressor through the V-belt, the free air is sucked into the primary cylinder through the intake filter, compressed to a certain pressure, and discharged to the primary and secondary intercoolers and separators. After cooling and separation of oil and gas, it enters the secondary cylinder, is further compressed to a higher pressure, and is discharged to the secondary and tertiary intercoolers and separators for cooling and filtering out the oil and condensate in the compressed air, and then enters the tertiary cylinder It is compressed to the final required pressure, and then enters the separator filter purifier to further remove the oil, condensate and oil vapor in the compressed air, so as to obtain cooled, clean and odorless high-pressure air filled into qualified high-pressure steel cylinders for use. The oil and condensate separated and filtered from the separators behind the cylinders of all levels are regularly discharged out of the machine through the drain valve or collected in the dirt tank.

After understanding what the high-pressure oxygen compressor is composed of, and clear about its work flow, we can better use and maintain the high-pressure oxygen compressor, scientific and safe use of the high-pressure oxygen compressor.
