Fully oil-free and oil-free lubrication differ mainly in concept and field of application.
Conceptually: completely oil-free means that in machinery or equipment, the original intention is to use no lubricating oil or grease at all. However, in actual operation, the surface of the parts may form an oxide film or be lubricated by gas containing lubricant molecules, so not all moving parts and friction surfaces are in a completely unlubricated state. This design usually has high requirements for material selection and processing accuracy to ensure that it can work normally without significant liquid lubrication. Oil-free lubrication is a specific lubrication method. It uses solid lubricants, coatings, surface treatments and other technologies to achieve good lubrication between friction pairs without liquid oil film. This method is usually used in some special working environments, such as high temperature, low temperature, vacuum, radiation, etc., or applications with strict restrictions on lubricants.
Application field: oil-free design is often used in occasions with high requirements for cleanliness, such as food, medicine, semiconductor and other industries, as well as some special working environment, such as vacuum, high temperature and so on. In these situations, even a small amount of lubricating oil may cause pollution to the product or the environment. Oil-free lubrication is widely used in various mechanical equipment, especially those who can not or inconvenient to use liquid lubricating oil. For example, in some high-speed, high-temperature, heavy-duty bearings, the traditional lubricating oil may not be able to form a stable oil film, then it is necessary to use oil-free lubrication technology to ensure the normal operation of the bearing.
In the field of air compressors, all oil-free air compressors, such as all oil-free piston air compressors, usually refer to air compressors with dry operation in the cylinder. However, please note that this does not mean that the transmission mechanism is not lubricated at all. In fact, the transmission mechanism may be lubricated by lubricating oil circulation. The air compressor discharge gas clean, no need to increase the degreasing device, suitable for high gas quality requirements of the occasion, such as painting, lathe to step up the plant gas power source, as well as oxygen, nitrogen machine supporting equipment. Oil-free air compressor means that there is no direct participation of oil in the entire operation process, and special materials and technologies are usually used to ensure life and efficiency.
The above information is for reference only. If you need to know more about oil-free and oil-free lubrication, it is recommended to consult a mechanical expert or consult relevant literature.
Technical Description on Conversion of Pressure Units In the field of pressure measurement, "kg pressure" usually refers to kilogram force per square centimeter (kgf/cm²), and the conversion relationship with megapascals (MPa) is as follows: unit definition: 1 kilogram force per square centimeter (kgf/cm²): representing per square centimeter
Air compressors (air compressors) play a vital role in the chemical industry, and their applications are wide and diverse. The following from the application scenarios, commonly used types, technical requirements and actual cases of four aspects, for your detailed analysis of the specific role of air compressor in the chemical plant: 1.
The maintenance cycle of the air compressor usually depends on the frequency of use, the use of the environment and the use requirements and other factors. Generally speaking, for the frequently used air compressor, the maintenance cycle should be more frequent. And the use of low frequency of air compressor, its maintenance cycle is
The precautions for the daily maintenance of the air compressor can be summarized as follows: Regular replacement of the filter element: The filter element is an important part of the air compressor and needs to be replaced regularly to ensure the normal operation of the air compressor and extend its service life. General recommendations according to the use of each
In the pursuit of efficient, environmentally friendly industrial era, oil-free air compressor with its unique advantages to become the new darling of the market. As a leader in the industry, the water-lubricated screw air compressor produced by Shanghai Granklin Group is based on its excellent performance and innovative design concept.
The main parameters considered in the selection of 1. air compressors 1. The traditional method of determining the compressed air requirements of a new plant with exhaust volume: add up the air consumption (m3/min) of all gas-using equipment, and then consider adding a safety, leakage and development coefficient
During the operation of the air compressor, condensed water will be generated due to air compression and temperature changes. If it is not properly treated, it may cause pipeline corrosion, equipment wear and pollution at the gas end. The following from the moisture generation mechanism,
The output pressure (pressure) of general industrial compressed air is usually determined according to the requirements of specific application scenarios, and the common range is between 0.2MPa and 1.0MPa (1MPa is approximately equal to 10 kilograms of force per square centimeter). This pressure range can cover the operating needs of most industrial equipment
Q: 21 cubic air compressor how many kilowatts? A: 0.8Mpa pressure about 132 kW, 1.0Mpa about 160 kW. (The actual gas volume shall be subject to the parameters provided by the manufacturer) Reference: Shanghai Granklin Group Water Lubricated Oil-free Air Compressor Product Hand
The specific value of the pipe network pressure of the factory air compressor is not fixed, it will be affected by many factors, including the design pressure of the air compressor, the design of the pipe network, the demand of the gas equipment and the operation status of the system. The following is the pressure on the factory air compressor pipe network
