The main difference between oil and oil-free air compressor is reflected in the following aspects:
material differences:
oil air compressor: its own material contains oily substances, which may cause pollution to the terminal equipment connected to it.
Oil-free air compressor: Its body material does not contain oily substances, thus avoiding the problem of oil pollution.
Service life:
oil air compressor: Because there is no heat-resistant piston, the sealing grease is easy to lose, resulting in dry wear damage to the bearing, so the service life is relatively short.
Oil-free air compressor: The heat-resistant piston is used, which can effectively prevent the loss of bearing grease due to high temperature, thereby greatly extending the service life of the air compressor.
Working principle:
oil air compressor: During operation, oil will participate in the compression process, take away the high temperature generated by the air compressor during compression, and provide a cooling effect for the machine.
Oil-free air compressor: No oil is used in operation, whether it is an oil-free piston machine or an oil-free screw machine, they will generate a lot of high temperature during operation, but because there is no oil participation, other methods are needed to cool down.
Exhausting gas:
oil air compressor: oil lubrication, so the final discharge of the gas is oil-containing.
Oil-free air compressor: If the resin material is used for lubrication, the gas discharged is oil-free. However, please note that the oil-free air compressor is not completely oil-free, but the oil content is very small; the real oil-free air compressor is lubricated with resin materials.
In summary, the main difference between oil and oil-free air compressors is reflected in the material, service life, working principle and the nature of the exhaust gas. These differences make the two types of air compressors suitable for different application scenarios and needs.
Q: How to deal with the high pressure of the air compressor? Answer: 1. Check whether the loading pressure and unloading pressure of the air compressor are reasonable. 2. Check whether the air compressor pressure sensor and the actual pressure are caused by abnormal display.
The maintenance method of oil-free air compressor mainly includes the following aspects: regular inspection and cleaning: regularly check the fastening of the parts of the air compressor to ensure that there is no looseness. Clean the outside of the air compressor to remove dust and dirt to ensure good heat dissipation.
The role of the air compressor in the cold dryer is mainly reflected in the following aspects: 1. removal of moisture and impurities Air compressor in the process of compressed air, will produce a lot of water vapor and impurities. If these moisture and impurities enter the production process directly, it will not only reduce the machine's
In the medical industry, the application of air compressor is very important, it is directly related to the treatment effect and life safety of patients. The water-lubricated screw air compressor produced by Shanghai Granklin Group has shown excellent performance in the medical field with its high efficiency, environmental protection and stable performance.
The filter replacement cycle in the air compressor system is not fixed, but based on a variety of factors. The following are some recommended replacement cycles and considerations: Oil-water separation filter: For air compressors that operate for more than 8 hours a day, it is recommended that every 3
The demand for compressed air in the production process of glass factory is usually large, and its application scenarios are extensive and critical. For example, pneumatic tools (such as cutting and grinding equipment) rely on compressed air as a power source;
The air volume calculation of the ship air compressor should be combined with the specific purpose, equipment parameters and industry standards. The following are the key steps and key points: the basic formula of 1. air volume calculation The basic formula of air volume (Q) of the air compressor is: Q = V / T Q: air flow (unit: m & sup3;/min or L/s) V:
The compressed air pressure used in most production workshops is between 0.6 and 0.8 MPa, which can meet the needs of most gas-using equipment. The oil-free water-lubricated air compressor can not only provide this pressure stably, but also flexibly adjust it according to actual needs, which saves electricity and worry.
The air pressure (pressure) of the air compressor is usually set according to the specific application scenario to meet the gas demand of different industries. In common industrial scenarios, the output pressure of air compressors is mostly concentrated between 0.8MPa and 1.5MPa (I .e. 800,000Pa to 1,500,000Pa), which can be covered.
Air compressor storage tank belongs to pressure vessel. It is a pressure vessel specially used to store compressed air. It is mainly used to store the air compressed by the air compressor and release the compressed gas when needed. In accordance with relevant safety standards and regulations, such as the Pressure Tones
