The main function of compressor lubricating oil is to lubricate and seal the male and female rotors and bearings. In addition to lubricating, cooling and sealing the mechanical parts, it also plays a role in cooling the compressed gas.
However, in actual production work, if the lubricating oil coking will seriously affect the working efficiency of the compressor, when the coking is found, it should be dealt with in time.
(1) Slight coking phenomenon:
the exhaust temperature is high, the site has a bad smell, the current increases, the compressor oil viscosity increases, the acid value increases, the inner wall of the oil barrel has a small amount of asphalt-like coking, the system has more sludge, the oil filter is frequently blocked, the head rotor has paint film, etc.
Treatment method: replace the new oil, can be added online carbon cleaning agent, with new oil cleaning system after adding new oil.
(2) serious coking phenomenon:
the compressor cannot be started after shutdown, there are asphalt-like substances in the head, the head is stuck, the inner wall of the oil barrel has asphalt-like substances, and the compressor oil is honey-like.
Treatment method: change the oil in strict accordance with the oil change procedure.
If there is coking and deterioration in the used oil, it means that the used oil has been seriously aged (abnormal increase in viscosity and acid value) and the same type or compatible compressor oil needs to be replaced as soon as possible.
Operation method: empty the old oil under the hot engine state, and then add the carbon deposit cleaning agent to run for 48 hours, and empty the cleaning agent under the hot engine state. Clean the system for one or more times. After the above operations, use new oil to clean the compressor system for one or more times (the number of times of cleaning should be such that the difference between the acid value of the newly added oil and the new oil is not more than 0.1mgKOH/g), then add new lubricating oil, and take the working oil after 30 minutes of operation as the reference sample for filing.
From environmental protection and maintenance, of course, it is oil-free air compressor. Oil-free air compressor is a technical improvement of oil-free air compressor. The main difference between oil-free air compressor and oil-free air compressor is the oil content of the gas discharged from the exhaust port. Oil-free air compressor
The purchase of air compressors has corresponding standards according to different industries. Oil-free air compressors are generally used in some industries with higher air quality requirements. Laboratories and medical industries belong to them. For laboratories, oil and gas in oil air compressors will affect valves, nozzles and pollution.
Granklin Group 1 cubic water lubricated oil-free screw air compressor, oil-free air compressor is divided according to whether the compressed air contains oil, corresponding to oil air compressor or micro-oil air compressor, granklin air compressor is 100% oil-free with water lubrication.
The application industries of water-lubricated air compressors produced by Shanghai Granklin Group: university laboratories, chromatographic analysis, medical pharmacy, dentistry, food processing, construction engineering, chemical industry, machinery, environmental protection, meteorology, hydropower, spraying, sandblasting, PET Bottle blowing, leak detection, metallurgy, water treatment, printing, shipping, textile, petrochemical, electronics, instrumentation, tobacco, nitrogen production.
There are too many brands of oil-free air compressors. It depends on your specific needs, such as power/exhaust volume/exhaust pressure, which are all related to the price of oil-free air compressors. When buying a full oil-free air compressor, you can understand the advantages and disadvantages of different air compressor products. It is very important to choose a suitable air compressor brand. As a domestic brand, the water lubricated air compressor produced by Shanghai Granklin Group has a much lower market price than the imported brand, which is a better choice.
View detailsMany enterprises in the purchase of permanent magnet variable frequency air compressor, often because of the permanent magnet variable frequency air compressor industry is not familiar with, do not know what kind of permanent magnet variable frequency air compressor brand. Generally speaking, in the domestic market of permanent magnet variable frequency air compressor, choosing Shanghai Granklin Group is a good choice.
The filter elements of the air compressor include air filter, oil filter and oil filter. The three perform their respective duties and play different roles. Any failure of the filter element may cause problems in the operation of the air compressor. Today we will talk about the three filter elements of the air compressor. The air filter element and oil filter element of the air compressor are made of high-precision filter paper. Under normal circumstances, the service life is about 2000 hours. The filter element must be replaced as soon as possible to avoid damage to the host.
View detailsThe water lubricated oil-free air compressor uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil. Therefore, the water-lubricated air compressor provides 100 percent oil-free clean compressed air. Product features: 1, high efficiency, reliability
Safety operation procedures for air compressors: 1. Preparation before driving (1) Keep the lubricating oil in the oil pool within the scale range, and the brand of the lubricating oil should meet the requirements. (2) Check the amount of oil in the oil injector and should not be lower than the scale line. (3) Turn before driving
