Screw air compressor as a wide range of general machinery, is used in all aspects of production. According to the different lubrication methods, it can be divided into oil-free air compressor and oil-free 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 internal use of water as a cooling material, to replace the oil to solve the air compressor compression process of high temperature, so as to achieve 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.
There are significant differences between air compressor and adsorption dryer in function, working principle and application field. The following is a detailed comparison: 1. function Air compressor: The main function is to compress air to reduce its volume and increase its pressure, so as to meet various
Yes, when the pressure of the screw air compressor reaches the set upper limit, it will automatically stop. The automatic start-stop function of screw air compressor is usually monitored and controlled by pressure sensor. When the pressure of the air compressor reaches the set upper limit, the pressure sensor will send a signal
The cooling methods of screw air compressors are mainly divided into air-cooled and water-cooled, and each method has its own unique advantages and disadvantages and applicable scenarios. The working principle of 1. air-cooled cooling method: use the fluidity of air to take away heat, usually through radiators and fans
When the water content of the air compressor is large, it can be processed from the following aspects: check and optimize the drainage system: ensure that the drainage system of the air compressor is unobstructed, clean and maintain the drainage system regularly to prevent blockage or leakage. Check liquid separator and gas
In today's era of increasing emphasis on environmental protection and energy saving, oil-free water lubrication air compressor head with its unique advantages, has become the first choice of many industries. As a leader in the compressor field, Shanghai Granklin Group produces more water-lubricated screw air compressors.
The oil content of the air of the micro-oil screw compressor varies due to many factors, but usually does not exceed a certain standard. The following is a detailed answer about the oil content of micro-oil screw compressor air: oil content under standard working conditions: under standard working conditions, micro-oil screw
Biological fermentation is a mystery of nature, just like cooking, it needs just the right "seasoning" to succeed. The compressed air is an important "seasoning" in this process ". First of all, compressed air has to"
The 10 years of air storage tank is not a mandatory end-of-life period, but a design life. In fact, whether the gas storage tank can continue to be used after this period needs to be evaluated according to the actual situation. First of all, we should consider the manufacturing quality of the gas tank, make.
There are significant differences between screw compressor and scroll compressor in structure, working principle, performance and application. The following is a specific comparison of the two: structure and design: screw compressor: by a pair of parallel, intermeshing rotor (screw) structure
Common oil-free air compressor applications 1, gold plating, copper plating industry applications. In the cleaning process of electroplating, it is necessary to use a compressor to remove water from the surface of the object, and the use of an oil-free air compressor can keep the plating smooth. 2.
