Screw air compressor as a wide range of general machinery, is used in all aspects of production. According to the different lubrication methods, it can be divided into oil-free air compressor and oil-free air compressor. What is the difference between the two?
1. to different oil contents, oil-free and oil-free air compressors generally refer to the oil content of the gas discharged from the exhaust port of the air compressor. Generally, oil-free air compressors have a large oil content. Oil-free oil is not free, but the oil content is relatively small, about 0.01ppm. Therefore, this oil content can be used to distinguish oil-free and oil-free air compressors. There is a full oil-free air compressor, it is not the use of oil lubrication, but the use of resin material lubrication, so the exhaust gas does not contain oil called oil-free air compressor.
2. works differently. From a structural point of view, there is no difference between the bearings of oil-free air compressor and oil-free air compressor. But from the working principle, there are obvious differences between the two. Oil-free air compressor in the process of operation is not involved in the oil, whether it is oil-free piston machine or oil-free screw air compressor, they will produce a lot of high temperature in the process of operation, if there is oil air compressor oil The participation will take away the high temperature generated in the compression process of the air compressor, thereby cooling the machine.
3. oil-free air compressor is not involved in the oil, and in the process of compression may produce a lot of high temperature, easy to cause high temperature failure. In fact, the oil-free air compressor uses a special high temperature resistant material called Teflon or molybdenum disulfide, which replaces the oil to solve the high temperature in the compression process of the air compressor, thus achieving the purpose of oil-free compression.
Oil-free air compressor because of its water to lubricate the compressed gas is cleaner than the oil injection air compressor. So the food, medical and other industries often use oil-free screw air compressor.
The air compressor room of the pharmaceutical factory plays a vital role in the pharmaceutical process, and its main role is reflected in the following aspects: 1. Provide pure compressed air The pharmaceutical factory has extremely high requirements for the purity of the production environment. The air compressor room removes the moisture in the compressed air
The water content of air compressor system is a complex and changeable problem, which is affected by many factors, including air humidity, compressor type, operating conditions and subsequent processing equipment. The following is a detailed analysis of the water content of the air compressor system: 1. air compressor system
The safety operation procedures of screw air compressor mainly include the following contents: preparation before starting the 1.: the operator must be familiar with the structure, performance, working principle, operating procedures and matters needing attention of the air compressor, and undergo technical training and safety training.
There are significant differences between oil-injected air compressor and oil-free air compressor in many aspects. The following is a detailed comparison of these two air compressors: 1. Working principle Fuel injection air compressor: The compressor is driven by a motor to rotate, so that air enters the pressure through the air filter
Oil content ≤ 0.01 mg/m & sup3; The compressed air is very close to the oil-free state, but strictly speaking, it still belongs to the category of "micro-oil" and needs to be further judged in combination with specific application scenarios and industry standards. The following is a detailed analysis: 1. international standards for & l
The maintenance cycle of the screw air compressor usually depends on the use of the equipment and the manufacturer's recommendations. Generally speaking, the maintenance cycle of the screw air compressor can consider the following aspects: Operating hours: Many manufacturers recommend running the equipment for a certain number of hours
Air compressor in the normal operation, vibration is inevitable, but in the operation of the vibration is too large, will cause serious harm to the air compressor, the following air compressor vibration reasons are analyzed as follows: 1. start-up operation after the vibration: unit start
Compressed air system equipment start-up sequence of technical specifications as the core power source of industrial production, the equipment start-up sequence directly affects the system operation stability and energy efficiency performance. Now on the cold dryer, air compressor, suction dryer standard start-up
The compressed air in contact with traditional Chinese medicine shall meet the core standards of oil-free, dry, clean and sterile. The specific requirements are as follows: 1. oil-free requirements Oil control: compressed air shall not contain impurities such as lubricating oil to avoid polluting traditional Chinese medicine. Generally, the oil content is extremely low, such as less than 0
When discussing the efficiency of screw air compressors and centrifugal air compressors, we first need to understand the basic working principles and characteristics of these two air compressors. Screw air compressor, its working principle mainly depends on the two intermeshing screw gas compression. This air pressure
