According to the use can be divided into: refrigerator compressor, air conditioning compressor, refrigeration compressor, oil field compressor, natural gas filling station, rock drilling machine, wind tools, vehicle brakes, doors and windows with the opening and closing of the textile machinery, tire inflatable with the compressor for plastics machinery, mining compressor, marine compressor, medical compressor, sandblasting and painting with the compressor.
The air compressor is driven directly by an electric motor, which causes the crankshaft to rotate and the connecting rod to reciprocate the piston, causing the cylinder volume to change.
Because of the change of pressure in the cylinder, through the inlet valve so that the air through the air filter (muffler) into the cylinder, in the compression stroke, due to the reduction of cylinder volume, the compressed air through the role of the exhaust valve, through the exhaust pipe, the check valve (check valve) into the storage tank.
When the exhaust pressure reaches the rated pressure of 0.7MPa by the pressure switch control and automatic shutdown. When the pressure of gas storage tank drops to 0.5-0.6MPa, the pressure switch is automatically connected to start.
Extended information
Note:
1, the air compressor should be parked away from steam, gas and dusty places. The air inlet pipe should be equipped with a filtering device. The air compressor should be wedged symmetrically with pads after it is put in place.
2, often keep the outside of the storage tank clean. Prohibit welding or hot work in the vicinity of the storage tank. Gas storage tanks should be made every year hydraulic test, the test pressure should be 1.5 times the working pressure. Gas pressure gauge, safety valves should be made annually for a test.
3, the operator should be specially trained, must have a comprehensive understanding of the air compressor and ancillary equipment structure, performance and role, familiar with the operation and maintenance procedures.
4, the operator should wear good working clothes, lesbians should be hair braids into the work cap. It is strictly prohibited to operate under the influence of alcohol, shall not be engaged in things unrelated to the operation, shall not leave their posts without authorization, shall not be decided without authorization to replace the work of non-operators of the machine.
5, the air compressor before starting, according to the provisions of the inspection and preparation work, pay attention to open all the valves of the storage tank. Diesel engine start-up must be implemented after the low-speed, medium-speed, rated speed heating operation, pay attention to the meter readings are normal before running with load. Air compressor should gradually increase the load to start, each part of the normal before full load operation.
