Silent oil-free air compressor
1, the choice before buying. The choice of good quality, suitable for equipment requirements will be much less troublesome to use.
(1) Some brands of foreign companies generally have reliable quality, but usually the sales price has been high because of the production and transportation costs. Non-general companies and individuals are the first choices; and due to the rapid changes in the pursuit of brand and quality of domestic companies, similar products The improvement of quality is very fast. Some manufacturers have basically no difference in technical capabilities and abroad, and some have even exceeded foreign ones. It is advisable to consult with peers before the purchase or to search and compare keywords such as "silent oil-free air compressor", "silent oil-free air compressor" and "medical dental instrument" on the Internet.
(2) First, select the type of air compressor according to the air flow under the rated pressure of the equipment. The best choice for the air compressor is that the flow rate is slightly greater than the required flow rate, so as to prevent the leakage of some pipe joints causing the flow rate to keep up, and thus the pressure cannot meet the demand. Gas flow units usually have m3/h (m3/h) and L/min (l/min). 1m3 is equal to 1000L. Pressure is also a key factor. The maximum exhaust pressure of an air compressor must be consistent with the pressure required by the equipment. If the pressure is small, it cannot meet the equipment requirements. If it is too large, the purchase cost will increase. Pressure expression units usually have bar, kg/cm2 (commonly known as kilogram pressure). In addition, the rated power of the air compressor is not as large as possible, but it is necessary to select smaller power when the flow and pressure meet the requirements, which can save unnecessary power resource expenditures.
(3) With the improvement of health awareness and environmental protection requirements, many equipments are becoming more and more sophisticated. This imposes higher requirements on the air compressors that supply these devices with air. Therefore, the scope of application of oil-free air compressors is greater. The wider it is. Please confirm the equipment's specific requirements for gas source quality and installation environment. If the requirements are not high and do not care about whether the gas is oil-free, you can consider the cost-saving principle to choose some of the more noisy and discharge air with Lubricants are common industrial compressors; otherwise, silent oilless compressors need to be purchased.
2, the current mute oil-free air compressor host are using micro reciprocating piston compressor, if not this type, you can certainly determine this type of air compressor is not a silent oil-free air compressor, air quality can not be muted Oil-free air compressor requirements.
3, the technical parameters are complete and correct. The parameters identified by international convention include metric units and American units. It depends on whether the selected parameter identification is regular and accurate. Parameter identification simple manufacturers, because there is no relevant testing equipment, can not do such a technical parameter test, or some parameters do not meet the general technical standards, therefore, when the choice is recommended to the user to require the manufacturer to provide detailed parameters in order to make The right choice.
4. Whether the host passes the 3C and industrial product license certification. At present, most manufacturers have passed some certifications such as CE, but because they do not comply with domestic industry standards and do not pass domestic compulsory certification, there may be risks when they are used.
5, choose more convenient after-sales service manufacturers. Services should be considered from three aspects: the manufacturer's service to product knowledge; the service to accessories; and the service to after-sales maintenance. Because most of the domestic manufacturers of oil-free air compressors have small scale and small batch production, which leads to excessive competition among the peers, the price goes lower and lower, but the quality also decreases.
Mute oilless air compressor maintenance
1, pay attention to routine maintenance. Proper use and maintenance can extend the service life of air compressors and avoid or reduce the occurrence of failures.
2, mute oil-free air compressor itself does not contain any oily substances, avoid adding any oil and oily substances.
3, in strict accordance with the air compressor rated voltage, frequency, rated load work, the effect will be better and more secure.
4, when not in use, develop a habit of cutting off the power in a timely manner. When you move the air compressor or connect other equipment, you must turn off the power.
5. Be sure to operate in the pressure range set at the factory (general factory maximum pressure setting is 8bar, safety pressure relief 8.8bar), otherwise there will be danger of gas tank explosion. (Need special pressure, please contact the manufacturer to customize).
6. Pay attention to the power supply voltage and the nameplate of the air compressor. When the power supply voltage is higher than the applicable voltage of the air compressor, it may cause personal accidents and damage the air compressor. When the power supply voltage is lower than the applicable voltage of the air compressor, it may cause poor starting and even damage the motor.
7. The filter should be cleaned in time according to the use conditions, and the accessories and cable lines should be checked regularly, and the damage should be replaced immediately. The machine should be kept clean and dry without oil, in order to fully realize its performance. When the air compressor is not in use, the air in the air tank should be drained, the waste water in the tank should be drained, and stored in a dry environment.
8. Evacuate the gas tanks in time. It is recommended that they should be discharged at least once a week.
9, the correct use of the environment: the normal use of air compressor environment at 5 °C ~ 40 °C, shall not be placed in an unobstructed place, do not work in humid and dark place, rigorous in the storage of flammable and explosive liquid gas and dusty , multi volatile gas workplaces. Keep the environment tidy and avoid unnecessary accidents.
10. Please check and replace the intake filter regularly and regularly. After 300 hours of operation, check the frequency of the intake filter. Keep filters and silencers clean to avoid most problems. Unclean filters can reduce compressor performance and compressor life.
