nitrogen compressor for cylinder filling is a compressor used to pressurize nitrogen and deliver or store it.

Nitrogen has many applications in the national economy.


Laser cutting

 Nitrogen acts as a shielding gas in laser cutting. Medium-pressure nitrogen is mainly used to blow away oxygen, preventing metal cutting and surrounding oxidation at high temperatures during cutting, improving the cleanliness of the cutting surface and aesthetics.

2. Nitrogen storage

Generally, the outlet pressure of PSA nitrogen generator is ≤10barg. If the capacity of nitrogen generator is excessive, or if it is filled at night by peak and valley electricity, it is more economical. It needs to store nitrogen for later use. At this time, nitrogen is generally used. The compressor is pressurized to a pressure of 200-300barg and filled into a high-pressure bottle. Generally, a high-pressure bottle can be filled with about 10 cubic meters of nitrogen.

cylinder filling nitrogen blast compressor with air-cooling and water-cooling cooling modes, single-acting and double-acting structure, vertical and angle type, medium and high pressure, wind brand series Oil-free lubricating nitrogen compressor with excellent performance, stable operation, high efficiency and energy saving, long service life, widely used in nitrogen laser cutting, nitrogen canning, chemical industry, etc.

The friction pairs of the series of machines involved in gas compression are not lubricated with thin oil. The friction seals such as piston rings and guide rings are made of special materials with self-lubricating properties. The structural advantages are reflected in:

1 There is no thin oil lubrication in the whole compression system, which avoids the possibility of oil contact with high pressure and high purity nitrogen (vertical nitrogen compressor is not completely oil-free type);

2 The whole system has simple machine structure, convenient control and easy operation;

3 For the gas medium of the compressor, nitrogen, no pollution, the purity of the nitrogen at the inlet and outlet of the compressor is the same.

The nitrogen compressor blast for cylinder filling is a completely oil-free nitrogen compressor, which requires the use of ordinary lubricating oil, but the nitrogen chamber is separated from the lubricating oil. During operation, the nitrogen is always clean and oil-free, suitable for the inlet pressure 4-8BARG. Exhaust 150-350BARG, small flow demand, mainly used for nitrogen pipeline pressurization, nitrogen filled bottle storage, suitable for 24 hours continuous operation, low maintenance cost, simple operation, safe and reliable

24hours working oil free nitrogen filling compressor GSW-90-4-200 (1)

This cylinder filling screw blast nitrogen compressor features

W-type cylinder compression, air-cooling method is convenient for customers, and water-cooled cooling mode ensures good cooling effect of the compressor, can effectively extend the service life of key wearing parts, and the inlet is equipped with low intake pressure protection, exhaust end It is equipped with high exhaust pressure protection and high exhaust temperature protection. Each stage is equipped with a safety valve and a temperature display. If over-temperature and over-pressure, the system will alarm and stop, ensuring safe operation. There is a forklift at the bottom of the compressor. Very convenient transfer site.
