Screw air compressor as a wide range of general machinery, is used in all aspects of production. According to the different lubrication methods can be divided into oil-free air compressor and 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 water lubrication, so the discharge of the 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 water to replace the oil to solve the high temperature in the air compressor compression process, 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.
Q: air compressor storage capacity to choose how many appropriate? A: according to the actual use of gas to reserve about 20%, choose air compressor and storage tank is better. The volume of the air storage tank should be between 10% and 20% of the exhaust volume of the air compressor. We generally choose 15% when
Air compressor maintenance time is an important factor related to equipment performance, efficiency and life. In order to ensure the stable operation of the air compressor, a reasonable maintenance plan is essential. The following is a detailed description of the air compressor maintenance time: 1. Routine maintenance cycle 1. New
When the pressure of the air compressor reaches the preset value, but the flow rate fails to reach the desired level, it often means that the working state of the air compressor is not optimal, or there are some factors that affect the flow rate. The following is a detailed analysis of this situation: First, the pressure of the air compressor
The replacement cycle of the air compressor filter element needs to be comprehensively determined according to the three elements of operating conditions, environmental cleanliness, and filter element quality. The following are specific guidelines: 1. routine replacement cycle Use scenarios Air filter element Oil filter Oil separator
Whether the pipeline of air compressor belongs to special equipment depends on its working pressure, volume and pipe diameter. Generally speaking, as long as the working pressure of the gas tank and the connected pipeline is greater than or equal to 0.1Mpa, and the pipe diameter is greater than or equal to 25mm, it belongs to special equipment.
The pressure range of compressed air is quite wide, depending on the application scenario and equipment requirements. The following are some common compressed air pressure ranges: Low pressure air: The pressure is usually between 0.1 and 1.0 MPa (megapascals). Compression of this pressure range
Oil-free compressor and oil-injected screw compressor advantages and disadvantages of comparison 1, the use of the situation is not the same: in the oil-free screw compressor operation, the lubricating oil is not in contact with the compressed gas, compressed gas is not contaminated. Oil-injected screw compressors inject large during compression
Power plants have strict requirements on the oil content of compressed air, usually requiring an oil content of no more than 0.1 mg/m & sup3;(ISO 8573-1 Level 2) or lower, and some key systems even require ≤ 0.01 mg/m & sup3;(Level 1). Specific requirements due to system use and industry standards
As an indispensable equipment in the industrial field, the safety and stability of the air compressor has a vital impact on the normal operation of the enterprise. In order to ensure the safe operation of the air compressor, a series of safety issues need to be checked regularly. The following is based on
The water supply of the water-lubricated air compressor is controlled by the system. The water vapor cylinder will replace the pure water many times to replace the water in the head of the water-lubricated air compressor. Water replenishment is not performed at one time. Without affecting the work of the water-lubricated air compressor head, the lubrication water can be replaced many times to achieve the purpose of automatic water replenishment.
