MANUTENÇÃO PREVENTIVA DE COMPRESSOR A AR TIPO DE PISTÃO E A IMPORTÂNCIA DO ENGENHEIRO MECÂNICO EM CONFORMIDADE COM A NORMA REGULAMENTADORA

Abstract

The preventive maintenance of the compressors is directly linked to the safety standards of the competent agencies and are ignored by many due to lack of knowledge. Therefore, it is up to the mechanical engineering professionals to comply with the standards as well as the management, supervision and control of this activity. Maintenance is the technique of keeping in perfect condition and functioning: equipment, accessories and everything connected to the manufacturing sector of an industry. The maintenance of the equipment in satisfactory conditions means a longer useful life and this is only achieved through an adequate and efficient maintenance system. In preventive maintenance, as the name implies, the mechanic must predict the life of the equipment. For this type of maintenance, the mechanic requires "intuition" and greater technical knowledge. Mechanics are no longer just parts changers, they become really qualified professionals. The main objective of preventive maintenance on equipment is to avoid or mitigate the consequences of failures. Compressors are mechanical devices that reduce the volume of any type of gas in order to increase its pressure thus, considerably a pressure vessel. In this equipment the air is compressed in a pneumatic system, so that it can be used to pull, push, perform work or develop power. The piston compressor is one of the oldest models of compressors, but it remains the most versatile and is still a very efficient compressor. The alteration, repair and maintenance project can be conceived by a specialized firm, as long as it is registered with CREA and has a legally qualified technician.
