Nowadays, oil-free air compressors are favored by many consumers. Among them, oil-free air compressors have many unique characteristics and benefits. In fact, oil-free air compressors generally do not contain any oil. What is really oil-free is oil-free air compressors. Air compressors lubricated with resin materials are the real oil-free air compressors. General oil-free air compressors only contain very little oil.
So now we focus on the two, to see the advantages of oil-free air compressor and its difference with oil air compressor.
1. From the perspective of oil content, oil and no oil in the air compressor generally refer to the amount of oil content in the gas discharged from the air compressor exhaust port. Generally, the oil content of the oil machine is relatively large, while the oil content of the oil-free oil machine is 0.01ppm, so the oil content is used to distinguish the oil and no oil in the air compressor. There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of resin material lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.
(2) From a structural point of view. There is no difference between the bearings of an oil-free air compressor and an oil-free air compressor. However, there is a big difference between the two in terms of working principle. The whole oil-free air compressor has no oil participation in the operation process. Whether it is an oil-free piston machine or an oil-free screw machine, they will generate a large amount of high temperature during the operation. If it is an oil-free air compressor, the high temperature generated during the compression process will be taken away, thus the mechanical cooling. The oil-free air compressor does not have the participation of oil, and a large amount of high temperature will be generated in the compression process. In practical application, a special high temperature resistant material called Teflon or molybdenum disulfide is used to replace the oil. The high temperature in the compression process of the air compressor is solved, thus achieving the purpose of oil-free compression.
3. Oil-free air compressors are cleaner and more environmentally friendly than oil-free air compressors. Hospitals, laboratories, schools, etc. will give priority to the use of oil-free air compressors.
It can be said that there is a big difference between oil-free air compressors and oil-free air compressors, and the natural application fields are also very different.
The food industry with large demand for air compressors mainly includes baked goods, beverage production, dairy processing, snack manufacturing and fermented food. The demand for air compressors in these industries is concentrated in oil-free, stable gas supply and energy saving. The specific analysis is as follows: 1. baking
In the field of air compressors, different types of air compressors have different requirements for operating conditions. In particular, the unique working principle of the water-lubricated screw air compressor produced by Shanghai Granklin Group raises the question of whether the air compressor needs water for operation.
A pressure of 13kg can be converted to 1.3MPa (megapascals). Since the pressure of 1kg is equal to 0.1MPa, the pressure of 13kg is equal to 13 x 0.1MPa = 1.3MPa. In physics, pressure refers to the vertical force on a unit area, using the formula P = F/S table
The specific value of the workshop atmospheric pressure is not a fixed value, but will be affected by a variety of factors, including geographical location, altitude, climatic conditions and the internal environment of the workshop. Here are some general descriptions of the atmospheric pressure in the workshop: 1.
Oil-free air compressor is widely used in many fields because it can provide high-quality, oil-free compressed air. The following are some of the main applications: Food industry: In food processing and packaging, oil-free air compressors are used to provide high quality
Cold dryer and air compressor are not special equipment. Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipes, elevators, lifting machinery, passenger ropeways, large-scale amusement facilities and special facilities in the field (factory) that involve life safety and are more dangerous.
The air compressor can be loaded for a long time under normal conditions, but it needs to be judged and adjusted according to the specific usage, environmental conditions and maintenance work. The following is a detailed analysis of this problem: 1. can be added for a long time.
Oil-free air compressor and oil-free air compressor have their own advantages and disadvantages, and the specific choice of which type of air compressor should be determined according to the use environment and needs. The advantage of the oil air compressor is that the lubrication effect is good, and the use of lubricating oil can effectively reduce friction and wear, thereby
Specifications for Operation and Maintenance of Air Compression System 1. Specifications for Operation of Air Compression System Preparation before startup Check the shift change record book to understand the operation of the equipment in the previous shift. Check the cooling water system: the circulating water pipeline valve should be in the closed state; the air compressor cooling water into
In the process of microbial fermentation feed production, air compressor is one of the key equipment, and its function runs through many links of fermentation process. Granklin water-lubricated screw air compressor with oil-free clean, stable and efficient technical characteristics, can provide a reliable gas source for microbial fermentation.
