Characteristics of the air compressor

Characteristics of the air compressor:By the motor directly drives the compressor, so that the crankshaft to produce rotary motion to drive the connecting rod so that the piston reciprocating motion, causing the cylinder volume change. Air due to pressure changes within the cylinder through the intake valve into the cylinder after the air filter (muffler), due to the narrowing of the cylinder volume in the compression stroke, the role of compressed air through the exhaust valve, the exhaust pipe, one-way valve (check valve) into the gas tank, and automatically shut down by the pressure switch control when the exhaust pressure to rated pressure of 0.7MPa. When the gas tank pressure down to 0.5 - 0.6MPa pressure switch automatically join the start.


Working pressure of the gas source should be about 20% higher than the maximum working pressure in the pneumatic system, to consider the loss along the way and partial loss of the gas pipeline. If some parts of the system pressure to low pressure relief valve to gas supply. Rated discharge pressure of the air compressor is divided into low voltage (0.7 ~ 1.0MPa), medium pressure (1.0 to 10MPa), high pressure (10 ~ 100MPa) and ultra-high pressure (100MPa or more) can be selected according to actual demand. Common use of pressure is generally 0.7-1.25 First, select the type of air compressor air compressor features. The pneumatic system pressure and flow two parameters to determine the air compressor output pressure pc and the inhalation flow rate qc, and ultimately select the air compressor models.


To make the air compressor to normal and reliable operation to ensure that the service life of the unit are required to develop a detailed maintenance plan, the implementation of fixed-man operation, regular maintenance, regular inspection and maintenance of air compressor to keep clean, no oil, no dirt.


Moisture in the air may condense in the oil and gas separation tank, especially in wet weather, when the exhaust temperature is lower than the air pressure dew point or shutdown cooling, there will be more condensed water precipitates. Oil contains too much moisture will cause the emulsification of lubricating oil, affecting the safe operation of the machine,


Each run of the air compressor 2000h for the removal of the cooling surface of dust, the need to purge the coolers on the fan bracket to the manhole cover open, with dust blowing air gun cooler purge until the cooling surface dust purged. Yet if the cooling surface dirt serious, difficult to clean, purge, and can to remove the cooler, pour the oil cooler and four import and export closed to prevent dirt from entering, and then use compressed air to blow dust or water on both sides of rinse, and finally drying the surface of the water stains. Back in place.
