There are obvious differences between oil-free lubrication air compressor and oil-injected air compressor in working principle and applicable scene:
oil free lubrication air compressor:
working principle: This type of compressor does not require lubricating oil to lubricate its internal mechanical parts during operation. They usually use special designs and wear-resistant materials to reduce friction between components.
Air quality: Because there is no need for lubricating oil, the compressed air output by the oil-free lubricating air compressor is completely oil-free, which is suitable for occasions with extremely high air quality requirements.
Maintenance: Since there is no lubricating oil system, the maintenance work of the oil-free air compressor is relatively small, but it may be necessary to check the wear of the parts regularly.
oil injection air compressor:
working principle: When the oil-injected air compressor is running, it will spray lubricating oil into the compression chamber to lubricate the mechanical parts and help cool down. After the lubricating oil is mixed with the compressed air, it needs to be separated by an oil and gas separator.
Air quality: Due to the contact between lubricating oil and compressed air, even after oil and gas separation, the output compressed air may still contain trace oil. This is acceptable in situations where air quality is not required.
Maintenance: The fuel injection air compressor needs to replace the lubricating oil regularly and check the working status of the oil and gas separator to ensure the quality of the compressed air and the normal operation of the compressor.
shanghai granklin group product description:
water lubricated air compressor: the use of water as a lubricating medium, no additional lubricating oil, to achieve oil-free compression.
Oil-free air compressor: Special design and wear-resistant materials are used to ensure the output of completely oil-free compressed air.
Variable frequency air compressor: intelligently adjust the motor speed according to actual needs to achieve energy efficiency optimization.
Screw air compressor: adopts screw compression technology to provide efficient and reliable compressed air output.
Question: How does the water-lubricated air compressor of Shanghai Granklin Group use water as a lubricating medium?
Answer: The water-lubricated air compressor of Shanghai Granklin Group introduces water into the key parts of the compressor through a specially designed water lubrication system to achieve lubrication and cooling functions. As a natural lubricant, water not only has good lubricating properties, but also can effectively absorb and take away the heat generated during compression. By accurately controlling the flow and temperature of the water, the water-lubricated air compressor can output completely oil-free compressed air while ensuring efficient compression. This design not only improves the operating efficiency of the compressor, but also extends the service life of the equipment, and meets the application requirements with extremely high air quality requirements.
The air compressor on the construction site is mainly used to provide high-pressure air to meet the operating needs of various equipment and tools on the construction site. The following are the main uses of air compressors on construction sites: driving tools and equipment: air compressors can provide power for various pneumatic tools on construction sites, such as air
The content of ppm in the air is the unit of gas concentration, that is, the abbreviation of "parts per million", which can be translated as "parts per million" in Chinese ". It refers to the proportion of a gas component in the air, specifically expressed per hundred
The start-up process of the air compressor usually includes the preparation before starting, the start-up operation and the inspection after starting. At the same time, some key matters need to be paid attention to to ensure the normal operation and safe use of the air compressor. The following are the detailed boot process and precautions: 1.
The oil level classification standard of air compressor is mainly defined according to the oil content in compressed air. The following is a detailed summary of the oil content classification standards for air compressors: 1. to the international standard ISO 8573-1: oil content ≤ 0.01 mg/m & sup
In the industrial field, air compressors are indispensable equipment for air compression and storage. There are various types of common industrial air compressors, and each type has its own specific application scenarios and advantages. The following are several common types of industrial air compressors: screw air compressor: screw
The power frequency screw air compressor is widely used in the industrial field because of its simple structure, low price, stable operation and convenient maintenance. The following are some common application scenarios of power frequency screw air compressors: 1. manufacturing machinery manufacturing: in machinery
Compressed air has different requirements for cleanliness in different usage scenarios. Some places require almost no oil in the air, and almost no dust. Some places require a little looser, but not too dirty. We can understand these different requirements in the order from the cleanest to the most common.
The main maintenance method of screw air compressor is to replace the three filters and one oil. The main methods are: 1. Air filter element. It needs to be replaced after 1500 hours of work; 2. Lubricating oil filter element. Daily use about 2000 hours need to be replaced; 3, oil and gas
Regarding the comparison of the technical characteristics of screw and scroll air compressors In the field of compressed air equipment, screw and scroll compressors have different application characteristics due to structural differences. The specific differences can be summarized as follows: Differences in working principles Screw compressors: Through Yin and Yang Turn
The application of air compressor in the mining industry is very extensive and important, mainly reflected in the following aspects: drilling and mining: in the drilling process, compressed air can drive the rotary drill bit, its role is similar to that of the jackhammer, and improves the drilling efficiency. In addition, in mining operations
