Maintenance Of The Dental Chair
The dental chair unit is necessary equipment for dentists to treat patients; it has a high utilization rate and is a device that integrates gas, water and electricity. Daily maintenance is directly related to the service life of the equipment and the integrity rate of the equipment. Therefore, daily maintenance work is particularly important.
1. The first is the maintenance of the dental handpiece, which is a key component of the dental comprehensive treatment chair. In the process of use, in order to avoid cross-infection between patients, the dental handpiece must also be sterilized by high temperature and high pressure. To prolong the service life of your dental handpiece, special attention should be paid to daily maintenance.
Before the first use, apply one to two drops of high-speed lubricating oil to the bearing with an injection needle. Under normal circumstances, the handpiece head should be cleaned with cleaning lubricant once a day, and the miniature bearing should be cleaned once every 2 weeks of operation. The normal working pressure of 0.2~0.25Mpa should be maintained; when there is no water, the dental handpiece cannot idle; otherwise the bearing will be damaged. When the dental bur is blunt, replace it with a new dental bur in time, otherwise it will also affect the life of the bearing.
2. The maintenance of the dental chair is mainly the maintenance of the air circuit and the water circuit. The gas, water and electricity should be turned off after get off work every day. It is especially worth mentioning that after the gas is turned off, the gas in the lumen should be discharged with a three-way syringe, so as to prevent the pipeline from being under high pressure for a long time and causing the pipeline to age and rupture. Regularly clean the water filter according to the local water quality, and regularly drain the accumulated water in the pressure reducing valve of the air filter. Clean the powerful suction device and saliva suction device in time, and often take clean water to clean the pipeline. It is also important to pay special attention to the water pressure and air pressure, which must be within the specified range to avoid bursting of the filter and pipeline. The operating light and viewing light should not be switched on and off frequently, which will shorten the life of the bulb.
3. Maintenance of the patient chair. The transmission parts should be checked regularly, and the position of the mechanical transmission should be lubricated regularly. Electro-hydraulic transmission should regularly check the oil quantity and oil quality in the oil tank, and replenish and replace it in time when the oil quantity is insufficient or the oil quality is not good. The belt drive should pay attention to adjusting the tightness of the belt.
