Shanghai Granklin Group produces and sells water-lubricated air compressors. The whole machine is made of stainless steel without lubricating oil and uses water as a lubricant.
dry oil free air compressor introduction:
the crankcase of the fully oil-free compressor is of a dry structure, and the large connecting rod, small holes, and the front and rear main bearings of the crankshaft generally use double-port sealed grease-containing ball bearings.
Since no lubricating oil is in contact with the compressed gas source during operation, the discharged gas does not contain oil and gas, so it is welcomed by users.
However, the grease sealed in the bearing will evaporate and oxidize and decompose the grease due to the increase in temperature during long-term operation, and the thickener in the grease will also deteriorate and lose the thickening effect.
Due to the change of grease performance, the use effect drops sharply. If new oil is not added in time, it will directly damage the bearing and even the machine.
Reasons for high temperature shutdown of oil injection screw air compressor:
the reason for the high temperature shutdown of the screw air compressor-the radiator is blocked. The compressor works in a dusty environment for a long time. After a certain period of use, there will be a layer of dirt on the surface of the radiator, and the interior will also form a blockage, which is easy to cause poor heat dissipation.
Fan blade fault. The fan blade is broken or loose, which affects the heat dissipation effect, resulting in high temperature of the equipment. Dirt of oil filter. There is dirt in the oil filter, the amount of oil entering it will be reduced, and there will be a certain resistance. The screw air compressor will not achieve the lubrication effect due to lack of oil.
The air compressor is an oil-free air compressor, and the friction parts are self-lubricating, so do not add lubricating oil. The air compressor must be fixed on a ventilated, stable and solid working surface. In order to reduce noise and vibration, it must have a shock absorber.
The filter medium (foam sponge or felt) in the filter should be cleaned every three months, blowing off the dust on the medium, if necessary, wash with water, dry and reuse. The compressor shall be maintained at least once a quarter. The maintenance contents include thoroughly removing dust and dirt outside the compressor, checking and fastening connecting bolts at all parts of the compressor, checking whether the grounding wire is in good condition, and checking whether the electrical circuit is aging or damaged.
The water-lubricated air compressor produced by Shanghai Granklin Group uses water-lubricated compressed gas without oil. It is the backbone of the new generation of compressor industry. Water lubricated air compressor can be used in more scenes with higher requirements for gas. Oil-free air compressor is more environmentally friendly and energy-saving. Advantages of oil-free air compressor: drying and eliminating bacteria: filters with different precision requirements can be selected according to different needs of the industry, so as to ensure the use results and promote the satisfaction of users.
View detailsNo oil is used in the compression chamber. Oil does not come into contact with compressed air, but does not remove the oil vapors contained in the atmosphere. This makes the compressed air still contain a small amount of oil impurities. After measurement, the oil content in the compressed air produced by the oil-free air compressor and the area where it is located
Traditional air compressor lubricating substances used in the oil, then the oil-free screw air compressor is through what lubrication? Common water as a lubricating substance can be done in the air without oil, compression process without oil involved in compression to maintain the purity of the gas.
View detailsNow many enterprises with high gas quality will choose oil-free screw air compressor. Therefore, the quality of oil-free screw air compressor is more important for screw air compressor. However, there are many factors that affect the quality of compressed air, not only the air compressor itself, but also the poor environment and improper operation may lead to the decline of compressed air quality and fail to meet the production requirements. Therefore, if you want to make your oil-free screw air compressor continuously produce high-quality compressed air for you, then you must ensure that you give him a good working environment. So what are the requirements for the use of oil-free screw air compressor to the environment?
The water-lubricated oil-free 5.5 kW screw air compressor produced by Shanghai granklin Group is neither big nor small. Compared with high-power models, 5.5 kW air compressor is already mini. The size of the machine means that the internal structure needs reasonable distribution. When purchasing water-lubricated air compressors, small models will drink less, whether they are freight or accessories, etc. Therefore, some customers do not need to consider this freight when purchasing air compressor equipment. A small forklift truck can fork hundreds of kilograms of equipment.
View detailsWe can be selected for purchasing water-lubricated air compressors, oil-free and water-lubricated air compressors, integrated air compressors and frequency conversion air compressors. Contact Xiao Shen of Shanghai granklin group, and I will match you with screw air compressors suitable for your needs.
Can the process gas air compressor use the water lubricated air compressor produced by Grantklin Group? The compressed gas used in different petroleum and chemical fields is different. Realistically speaking, not every kind of gas is suitable for the use of water lubricated air compressor, in the oil-free air compressor is currently the best use of water lubricated air compressor, but the different characteristics of the gas determines whether the appropriate use.
View detailsAir compressor pumping slow, is a lot of air compressor old users will encounter the situation, why is this. How long is the durability period of wearing parts?
For medicine, food, semiconductor, chemical industry, fermentation and other industries, oil-free and clean compressed air must be the first choice. Oil-free oil-free screw air compressor, water-lubricated oil-free screw air compressor, oil-free scroll air compressor and oil-free centrifugal air compressor are common oil-free.
1. check the protective device and safety accessories before starting, and can only start when they are in good condition. 2. check whether the lubricating surface is up to standard. 3. water-cooled air compressor to open the cooling water valve, and then open the motor. No cooling water or water cut-off
