Hongbo Brand nitrogen air compressor/booster packing machine
Application and Application Scope of All Oil-Free Oxygen Gas Supercharger
1.1A fully oil-free oxygen gas booster (hereinafter referred to as supercharger) is a reciprocating plug, single action (see figure 1 for the appearance of the whole machine), this product does not need to be added Lubricating oil, no pollution of pressurized oxygen, full sealing structure, no leakage operation, bearing all added imported special grease to ensure the product durable。
1.2 This compressor is generally suitable for rated intake pressure ≤0.4 Mpa (above this pressure add pressure relief valve, reduced to 0.4 Mpa), rated exhaust pressure Force 15 Mpa under the working conditions of filling bottles, inverted bottles and other oxygen pressurization, recovery occasions. When the intake pressure is below 0.4 Mpa、the exhaust pressure is above 15 Mpa. The use of compressors under special conditions, need to communicate with our technical personnel after the distribution, and then production and use. General compressor type Non-explosion-proof models can only be used in non-explosion-proof occasions. Explosion-proof occasions need to communicate with our technical personnel to select explosion-proof models.
Working Principle and Structure of Supercharger
2.1 principle of operation
2.1.1 Supercharger consists of main engine, motor, instrument and electrical control elements.
2.1.2 When the supercharger is working, the motor drives the crankshaft to produce rotating motion through the triangle belt drive, and the piston produces reciprocating motion through the connecting rod, which causes the cylinder volume to change, resulting in the increase of oxygen pressure in the cylinder. Oxygen is injected into the buffer tank through the exhaust valve, one-way valve and pipeline for use.
Maintenance and Inspection of Supercharger
3.1 Check the following daily
3.1.1 Check the connection for loosening, if any, should be fastened immediately.
3.1.2 Pressure gauge: the pressure gauge pointer moves smoothly, when the oxygen pressure in the gas storage tank is 00:00, its pointer should also refer to "0".
3.1.3 Calibrate the pressure controller. When the exhaust pressure reaches the rated pressure, the pressure controller should be able to cut off the control circuit of the magnetic starter and make the supercharger stop working, otherwise it should be adjusted according to 3.3.3.
3.1.4 Safety valve: when the exhaust pressure is close to the setting pressure, the exhaust relief valve should produce discharge action.
3.2 Monthly maintenance
3.2.1 Belt elongated or worn, movable motor, adjust belt tightness or replace belt according to 7.1.2.
3.3 Annual periodic inspection projects
3.3.1 Check for air leaks
3.3.2 To check the wear of the guide ring of the piston ring, the wear limit of the piston ring is 5.5 mm; the wear limit of the guide ring is 1.8 mm.
3.3.3 Connecting rod large head bearing and crankcase bearing are normal. When the compressor runs up to 2000 h, we should add special imported food grade aerospace grease to the roller bearing.
3.3.4 Booster is a special equipment, our company recommends users by professional regular maintenance 1~2 times a year.
