④、 Overview of working principle:
Working principle of compressor: oil-free air compressor is a miniature reciprocating piston compressor. The motor driven by a single shaft and has a symmetrical distribution of crank and rocker mechanical structure. The main motion pair is piston ring, and the secondary motion pair is aluminum alloy cylindrical surface. The motion pair self-lubricated by the piston ring without adding any lubricant. The reciprocating movement of the crank and rocker of the compressor makes the volume of the cylindrical cylinder change periodically, and the volume of the cylinder changes twice in opposite directions after the motor runs for one week. When the positive direction is the expansion direction of the cylinder volume, the cylinder volume is vacuum. The atmospheric pressure is greater than the air pressure in the cylinder, and the air enters the cylinder through the inlet valve, which is the suction process; when the opposite direction is the direction of volume reduction, the gas entering the cylinder is compressed, and the pressure in the volume increases rapidly. When the pressure is greater than the atmospheric pressure, the exhaust valve opened, and this is the exhaust process. The structural arrangement of single shaft and double cylinders makes the gas flow of the compressor twice that of the single cylinder when the rated speed is fixed, and makes the vibration and noise generated by the single cylinder compressor well solved, and the overall structure is more compact.

Working principle of the whole machine (attached figure)
Air enters the compressor from the air filter, and the rotation of the motor makes the piston move back and forth to compress the air. So that the pressure gas enters the air storage tank from the air outlet through the high-pressure metal hose by opening the one-way valve, and the pointer display of the pressure gauge will rise to 7Bar, and then the pressure switch will automatically close, and the motor will stop working. At the same time, the air pressure in the compressor head will reduced to zero Bar through the solenoid valve. At this time, the air switch pressure and the air pressure in the air tank drop to 5Bar, the pressure switch automatically starts, and the compressor starts to work again.

Product Overview

Because of its low noise and high air quality, dental electric oil-free air compressor is widely used in electronic dust blowing, scientific research, medical and health care, food safety, and community carpentry decoration and other workplaces;
The dental electric oil-free air compressor provides a quiet and reliable compressed air source for laboratories, dental clinics, hospitals, research institutes and other places. The noise is as low as 40 decibels. It can be placed anywhere in the work area without causing noise pollution. It is very suitable for being an independent gas supply center or OEM application range.
It is very suitable for being an independent gas supply center or OEM application range.

Performance illustration

The air compressor mainly involves the work of the compressed air system: the non-slip doctor’s chair and the multi-functional foot control device, the doctor can control it with his feet during the treatment process, and realize the operation of water and air guns without stopping the operation of the equipment. switch action.
Dental air compressors pressurize the air used in surgery. Standard compressors are not suitable for this purpose as they may not meet health and safety standards. Dental companies can choose from a range of models designed for small, medium and large practices with various functions. Like other equipment in the practice, dental air compressors can also be inspected by health department officials to confirm that they are safe for use on patients.
The oil-free air compressor produces clean and oil-free compressed air, which is extremely beneficial to the health of patients with oral diseases, as well as environmental sanitation and environmental protection. In dental treatment work, photocuring, glass ionomers, ceramics, etc. have high requirements for air sources (air compressors). If the compressed air contains oil molecules, the combination and firmness of photocuring will not meet the standards. The quality cannot be guaranteed, which will ultimately affect the quality of treatment. Similar situations will occur in other dental treatments such as glass ionomers.

Compressed air in the medical industry is almost always required to be oil-free. The dental chair is mainly used for oral surgery and oral disease inspection. The air compressor mainly involves the work of the compressed air system: the non-slip doctor’s chair and the multi-functional foot control device, the doctor can control it with his feet during the treatment process, and realize the operation of water and air guns without stopping the operation of the equipment. switch action.
Generally, medical air compressors must use oil-free and quiet air compressors. This is not difficult to understand. The compressed air in the initial state is not pure, and contains a large amount of relative impurities such as moisture. After mechanical compression, the lubricating oil in the machine may also be mixed in the compressed air. Therefore, an oil-free air compressor is a more appropriate consideration. The compressed air it produces is relatively pure after treatment; both medical air compressors are mostly indoors, and the medical environment requires no noise pollution, so oil-free silent air The press is used a lot.
Another thing to note is the daily exhaust of the supporting air compressor.
After the daily work, the air compressor gas is exhausted and then turn off the main valve switch! If the machine pipeline is always inflated, it is easy to accelerate the aging of the trachea, and the spring elasticity of the pressure switch is weakened, which directly affects the working air pressure.
