Dental compressors are now playing a crucial role in the medical field. The correct use of dental compressor is not only responsible for customers, but also for their own health. This article will introduce the working principle and precautions of dental compressor.
1. Working principle of dental compressor
2.Precautions of dental compressor:
Dental compressor is a miniature oil-free reciprocating piston compressor, which is driven by a single shaft of the motor with a crank rocker mechanism with a wrong Angle of 180°. The main motion pair is a piston ring, and the supporting motion pair is an aluminum alloy cylinder.Through the reciprocating motion of the crank rocker, the travel volume of the cylinder is changed periodically by the compressor, and the travel volume of each group of cylinders will change in opposite directions twice each week when the motor runs.To axial movement, when the piston cylinder volume increases, as the negative pressure in cylinder, the atmospheric pressure is greater than the pressure in the cylinder, air through the intake valve into the cylinder, at this time for the suction process: when the piston movement to cover, into the gas in the cylinder is compressed, the rapid increase of the pressure inside the gas when the pressure is greater than exhaust cavity pressure, exhaust valve is opened, the exhaust process at this time.The structure of single shaft and double cylinder makes the dental compressor discharge twice as much as that of single cylinder. The vibration and noise generated by dental compressor are well improved due to the crank and rocker mechanism with the wrong Angle of 180°, and the overall structure is more compact.
Dental compressor is one of the main mechanical power equipment in many clinics and hospitals.Strict implementation of the dental compressor operating procedures, not only to extend the service life of the dental compressor, but also to ensure the safety of the compressor operators, we will understand the dental compressor operating procedures and precautions for the use of dental compressor.
1.When the dental compressor stops due to power failure, in order to prevent the starting of the dental compressor with pressure, the power off handle of the pressure switch should be lifted when the compressor starts again to clean the air in the pipeline and restart the dental compressor.
2. The user must install the compressor protection ground wire to ensure that all the metal shells of the compressor have good contact with the earth, and the ground resistance should meet the national standard.
3. When dental compressor finds serious air leakage, abnormal ring and peculiar smell, it should stop operation immediately, and then it can run again after the cause is identified, troubleshooting and recovery.
4. Dental compressor is an oil-free air compressor. The friction parts are self-lubricating, so do not add lubricating oil.
5. Dental compressor must be fixed on a ventilated, stable and firm working surface. In order to reduce noise and vibration, there must be a damping device.
6. Filter medium (foam sponge or felt) should be cleaned every three months - once, blow off dust on the medium, wash with water if necessary, air dry and then use.
7. Dental compressor shall be maintained at least once a quarter. The maintenance shall include cleaning the external dust and dirt of the compressor, checking and fastening the connection bolts of the compressor, checking whether the grounding line is intact, and checking whether the electrical line is aging and damaged.
