In the fields of biology, medicine, electronics, food, medical, automobile, chemical industry, etc., the water, oil, dust and bacteria in the compressed air are required to reach a high quality level. However, the water, dust and bacteria in the compressed air can be solved by a series of post-processing equipment such as filters and dryers, while oil removal is relatively difficult, however, we have some misunderstandings about oil-free air compressors and the compressed air they produce.
The compressed air produced by the oil-free air compressor is oil-free, which is not certain.
Although no oil is used in the compression chamber, the oil will not contact with the compressed air, but the oil vapor contained in the atmosphere itself cannot be removed, which 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 has a very close influence on the air quality, the environment of the air compressor room and the cleanliness in the compressor.
2. Oil-free air compressors do not use oil, which is not correct.
Although oil is not used to come into contact with the air in the process of compressing the air, oil is still used to cool the compressor and lubricate the operating parts so that the compressor operates normally and stably.
3. The compressed air produced by the oil-free air compressor is pollution-free and pure and clean. This is a wrong idea.
In fact, there are many pollutants in the atmosphere, including dust, water vapor, oil vapor, microorganisms and so on. The compressed air produced by the oil-free air compressor can only ensure that no oil is brought into the compressed air in the compression project, but the magazine in the air itself cannot be removed. This means that the compressed air produced by an oil-free compressor is not necessarily pollution-free, and the use of air treatment products can help reduce pollution to the required air quality level.
Oil-free air compressors do not require air treatment products, on the contrary, the higher the air quality, oil-free air compressors must also be equipped with post-processing systems.
It can be seen from the third point that the gas quality of the compressed air produced by the oil-free air compressor is largely subject to the environment, so users need to configure the corresponding post-processing equipment according to their own demand for compressed air quality to meet their own demand for compressed air quality.
5. The use of oil-free screw air compressor and low maintenance costs.
In fact, because the compression ratio is much smaller than the oil-lubricated compressor, the energy consumption of the oil-free machine is higher, and the gas production of the oil-free machine with the same power is more than 40% less than that of the energy-saving screw compressor. Although the compression chamber is not lubricated by oil, the grease and air filter in other parts still need regular maintenance. The core rotor is generally treated with special coating and has a service life. It has high requirements for water and is easy to be damaged. The maintenance of the main engine is a necessary option for no oil machine. The high cost of the pen can account for 50% of the equipment cost.
We believe that for most users, in fact, it is not necessary to truly level 0 oil-free compressed air, but more to solve the problem caused by oil impurities for mid-range equipment: refrigerated dryers, heat-free regenerative dryers, micro-heat regenerative dryers, etc. It is a choice to prevent the efficiency of post-processing equipment from declining or even losing its water removal function. For users who really need 0-level oil-free compressed air, it is difficult to obtain oil-free compressed air continuously and stably by selecting oil-free air compressor alone. It is still necessary to carry out oil removal filtration with corresponding oil removal post-treatment equipment to achieve the required compressed air quality.
What are the safety measures in the work of the air compressor?(1) When the compressed air is cooled, the oil-water mixture condensed in the cooler, air storage barrel and oil separator must be blown off in time, at least once per hour. (2) When the air compressor is working, if the cooling water supply is not timely, it must be parked immediately to be cooled.
1. Traditional air power: pneumatic tools, rock drills, pneumatic picks, pneumatic wrenches, pneumatic sandblasting 2. Instrument control and automation devices, such as tool replacement of machining centers. 3, Air jet loom with compressed air
buy air compressor in zhengzhou choose which air compressor manufacturers? shanghai granklin group co., ltd. is a long-term focus on machinery and equipment industry in the field. The company advocates "professional, pragmatic, efficient and innovative" spirit of enterprise, has a good internal mechanism. Engaged in screw air compressor manufacturing research and development.
1. After using it every day, it is necessary to check the oil level, exhaust temperature, exhaust pressure and other aspects of the screw air compressor to see if there is any abnormal situation. If the oil level is too low, it is necessary to add lubricating oil in time. In addition, there is a need
The normal operation of the factory is inseparable from the stability of the equipment, and the stability of the equipment is not only related to its performance, but also inseparable from the daily cleaning and maintenance. Correct maintenance steps can not only keep the equipment in good performance but also improve the product yield, but also
Oil-free air compressor is divided according to whether the compressed air contains oil, which corresponds to oil air compressor or micro-oil air compressor. Oil-free air compressors are distinguished according to different compression forms or different host structures, and manufacturers often choose suitable models according to actual needs. Several common oil-free air compressors are: oil-free piston air compressor, no
In the market, many enterprises will choose "screw air compressor" to compress gas. For enterprises with higher gas requirements, they will prefer to use "water lubricated air compressor manufacturer" and "oil-free water lubricated air compressor" produced by "Shanghai granklin group". At present, the performance and quality of domestic machines have surpassed foreign brands. "Shanghai Granklin Group" equipment stability, timely and thoughtful after-sales. In fact, the purchase of "air compressor" is these two points are very important.
(1) To fully meet the gas consumption of gas equipment, the maximum gas consumption should be calculated according to the type and quantity of pneumatic equipment, and the gas consumption that may be increased in the future should be included, and then the air compressor that can meet the gas supply requirements of pneumatic equipment should be selected.
The "air compressor head" produced by "Shanghai granklin group" is used in the "water lubricated air compressor" produced and sold by itself. for the "air compressor head", an enterprise specializing in the production and manufacture of "granklin air compressor", we strictly control the quality of the "air compressor head" under the condition of completely using the self-produced "air compressor head.
The screw air compressor needs to be drained every once in a while, which is recognized by the industry. Even so, there will still be users will ask, do not drain, what will happen? Today we will answer this part of the user's questions. Undrained will first lead
