Medical oil-free air compressor maintenance
1, the working noise is very low: permanent magnet oil-free screw air compressor compared to ordinary compressors, the noise is much lower. The permanent magnet oil-free screw oil-free air compressor mostly works below the rated speed, so its host machinery has to reduce a lot in terms of noise and wear, and because of its low noise, it is also to a certain extent Extend the service life of the permanent magnet oil-free screw oil-free air compressor.
2. Low maintenance cost: Compared with ordinary compressors, oil-free air compressors have relatively troublesome maintenance. Although any type of compressor requires professionals to carry out maintenance in the prescribed order, the permanent magnet oil-free screw air compressor has a lower maintenance cost in all compressors because it uses a high-efficiency and energy-saving control system, which not only has a small impact on the power grid and machinery, but also prolongs the service life of various parts. The mechanical properties are good. The single screw compressor is a rotary compressor without vulnerable parts such as air valves and piston rings, so it has high reliability and can work for a long time without maintenance or fixed foundation. Single-screw compressor is different from twin-screw compressor, radial force and axial force are automatically balanced, and the speed is low, so this kind of machine has low vibration, low noise and long bearing life. The specific power is low. Due to the effect of water, the air volume per unit horsepower is 25% higher than that of the general dry compressor.
Reduce production losses: Because the high-efficiency and energy-saving control system used by the permanent magnet oil-free screw air compressor is highly intelligent, the permanent magnet oil-free screw air compressor can simultaneously have more than 20 parameters, current, voltage, etc. In other words, the permanent magnet oil-free screw air compressor can reduce its own downtime, reduce the loss of production, but also make the air system more stable and reliable.
The oil-free air compressor is composed of screw head, motor, oil and gas separation barrel, cooling system, air conditioning system, lubrication system, safety valve and control system. The whole machine is installed in a box, self-contained, and can be directly placed on a flat cement floor without being fixed on the foundation with anchor bolts. Now the twin-screw air compressor net will describe the advantages of oil-free screw air compressor and the disadvantages of oil-free screw air compressor respectively.
Oil-free screw air compressor advantages:
1. Because of the high viscosity of lubricating oil, the current oil removal equipment can not be completely removed, so that the oil-free air compressor compressed gas does not contain oil is irreplaceable.
2. At present, water removal equipment such as refrigerated dryers, heat-free regenerative dryers and micro-heat regenerative dryers lose their water removal function due to the oil in compressed air. The clean oil-free gas compressed by the full oil-free compressor fully protects the water removal equipment and reduces the additional capital occupation caused by the maintenance of the water removal equipment.
3. Using an all-oil-free air compressor to provide compressed gas to the outside will not greatly reduce the motor load due to the pressure loss caused by oil removal equipment, thus achieving energy saving effect; At present, the high-quality three-stage oil remover produces a pressure loss of 1 to 1.2kg during use. A 7.5KW air compressor will pay an extra 600W of power loss for every 1kg of pressure increase, and 6 degrees of electricity for every day of work (10 hours, for example), this will be a long-term intangible expense.
4. The use of oil air compressor greatly wastes lubricating oil. Taking a 7.5KW high-quality oil air compressor as an example, it consumes 5kg of lubricating oil every month, which will cost 60kg of lubricating oil more than one year. At the same time, in order to remove the oil in the compressed gas, it is necessary to use an efficient oil filter and replace the filter core many times, which is also a great expense.
Because the screw non-oil-water lubrication screw air compressor is a full series of stainless steel single screw host, it can save more than 15% energy than the secondary dry twin screw and more than 36% energy than the primary twin screw;
oil-free screw air compressor reaches the energy-saving level of oil machine; avoid frequent dry screw and high mainframe maintenance. Energy saving: Grankering single-screw main engine with high volumetric efficiency is adopted, which has low specific power and is more efficient and energy-saving than twin-screw oil-free air compressors.
Environmental protection: the host uses water lubrication, compressed air is not polluted, while avoiding waste lubricating oil, in line with environmental protection requirements.
Quiet: quieter than oil-injected single-screw compressor. Compared with oil-injected single-screw compressor of the same specification, the noise is lower by 4-5db(A). Low operation and maintenance costs: since lubricating oil is not used, there is no need to exchange waste oil, oil filter screen, oil separator, etc., and the operation cost is lower.
If the injection phenomenon does not change, you need to check and replace the oil. Air compressor is an important equipment in industrial production. In the purchase of equipment accessories, the original accessories must be selected to ensure the quality of maintenance.
If hidden dangers are found during use, timely repair shall be reported to ensure the normal operation of the equipment. So as to ensure the continuity and stability of enterprise production, so as to bring higher economic benefits to enterprises.
When the moisture in the compressed air is removed, it must be discharged from the system. A drain with an electric valve is a good way to ensure that the system does not leave the water. Check the drain to ensure adequate drainage; excessive water can cause problems and lead to bacterial growth. It is also important to ensure that the drain does not open for a long time.
The first-line brand of permanent magnet frequency conversion screw air compressor is also widely used in the industry. In order to ensure the better and stable operation of permanent magnet frequency conversion air compressor, users also need to know the daily maintenance methods of permanent magnet frequency conversion air compressor. Timely adjust the permanent magnet variable frequency air compressor
Contact information of oil-free air compressor manufacturers: At present, the main brands of oil-free air compressors in China are Granklin and so on.
Frequency conversion air compressor for lubricating oil quality requirements are much higher than the frequency air compressor, can not be used according to the standard selection of lubricating oil frequency air compressor. The reasons are as follows: 1. The frequency conversion air compressor is easy to accumulate water at low frequency, and the water resistance of the lubricating oil is much higher than that of the power frequency air compressor;
1. The possibility of the screw air compressor failing to start the air compressor failing to start causes this problem is much more likely than price, but experienced engineers generally consider the problem from the following aspects: First, whether the fuse is burned out, this is a common question.
In recent years, the voice of energy saving and emission reduction in China is getting higher and higher, and the demand for energy-saving equipment is also increasing. Increasing energy conservation has also become a realistic task facing the air compressor industry. Frequency conversion air compressor is an energy-saving air compressor, its advantages are as follows: advantages: set the pressure at will, and maintain a constant pressure. Oil-free air compressor is suitable for: municipal, mining, tunnel, exploration, petroleum, wharf, shipbuilding, power plant, drilling, steel plant, subway, highway, railway, airport, factory, hospital, ship, building, communication, mining, pipeline cleaning, construction machinery and other fields.
As a professional equipment that gets along with laboratory personnel for a long time, the noise control requirements of the machine are very high. The procurement of laboratory air compressors needs to be oil-free and quiet to provide a good working environment for laboratory staff.
Compressed air can be pressurized, cooling, adsorption and other methods to remove the water vapor, and can be through heating, filtration, mechanical separation and other methods to remove liquid moisture. Refrigerated dryer is a kind of equipment that cools the compressed air to remove the water vapor contained in it and obtain relatively dry compressed air. The rear cooler of the air compressor also uses cooling to exclude the water vapor contained therein. Adsorption dryer is the use of adsorption principle to remove the water vapor contained in compressed air.
No oil is used in the compression chamber. Oil does not come into contact with compressed air, but does not remove the oil vapors contained in the atmosphere. This makes the compressed air still contain a small amount of oil impurities. After measurement, the oil content in the compressed air produced by the oil-free air compressor and the area where it is located
For oil-free air compressor, most people will think that the air compressor uses air compressor oil during operation and adopts post-processing filtration to remove oil. In fact, this is one of our misunderstandings about oil-free air compressors. Air compressor oil has many functions, including cooling and lubrication. The so-called oil-free air compressor of Granklin air compressor uses water lubrication, and the compressed air is 100% oil-free.
Diesel screw machine diesel engine oil filter and diesel filter replacement should follow the diesel engine maintenance requirements, the replacement method is similar to the screw oil core. Maintenance and replacement of oil fine separator. The oil fine separator separates the screw lubricating oil from the compressed air
