With the development of science and technology, the requirements for mechanical equipment in industrial production are getting higher and higher. Now many enterprises are using oil-free air compressors to replace traditional air compressor equipment in order to ensure the quality of production. However, oil-free air compressor equipment is the same as ordinary air compressor equipment. They work continuously every time, so it is prone to problems and failures. What are the general manifestations of oil-free air compressor failures?
Oil-free air compressor failure will generally have what performance?
Poor performance 1. environmental ventilation and heat dissipation
there are three main situations in which the surrounding environment of the oil-free air compressor affects heat dissipation: first, it is too close to wall obstacles; Second, there are other heat sources near the oil-free air compressor; third, the front door and side doors of the screw air compressor fittings are open during operation, and the fan cannot form strong airflow.
Performance 2. fan tape broken or loose
when the tape breaks, the oil-free air compressor will automatically stop when it runs for about 5 minutes due to excessive temperature. If the tape is too loose, it will slip, which will reduce the fan speed and affect heat dissipation. At this time, the tightness of the fan tape should be replaced or adjusted.
Performance 3. exhaust pressure is too high
when the exhaust pressure exceeds the rated 12MPa, long-term operation will automatically stop due to excessive load on the compressor and diesel engine. At this time, first check and adjust the pressure valve, and then check the diesel engine throttle control system and exclude this fault.
Performance 4. oil and gas separator filter element is too dirty
when it is too dirty, the oil will affect the circulation due to excessive resistance, causing overheating and shutdown. This situation is judged from the pressure difference before and after loading. When the pressure difference at both ends is 3 times or more of the pressure difference at the beginning of the startup and reaches 0.1MPa, it should be cleaned or replaced.
If you find that your oil-free air compressor has the above performance, we need to find the right way to deal with it, otherwise it will affect the normal operation of the oil-free air compressor and the production schedule of the enterprise.
The "water-lubricated air compressor" produced by granklin group emits light and heat in various industries. as an "oil-free air compressor" product, water is used as a lubricating substance. there are many advantages, such as: compressed gas is 100% free of oil, and the overall temperature of the air compressor is lower.
Air compressor quotation needs professionals to match. Shanghai granklin group, a domestic air compressor manufacturer, is a professional air compressor factory integrating research and development, production and sales. In the air compressor quotation, we use professional knowledge and technical reserves to customize services from user needs to better serve users.
View detailsIn general, oil-free air compressors are used in the food industry, because the food industry is relatively demanding. Oil-free air compressor is not only oil-free, I still give you a comprehensive popularization of the basic advantages of oil-free air compressor! First of all, the machine body
More and more enterprises begin to purchase oil-free air compressors. There are many benefits of using oil-free air compressors, except that the higher price will make it more painful for bosses to pay. However, the oil-free air compressor does not have the participation of oil, and the oil-free air compressor also generates a large amount of high temperature during the compression process. How to solve the high temperature to ensure the normal operation of the machine
The "water-lubricated oil-free air compressor" produced by Shanghai Granklin Group is widely used in all aspects of the medical industry. The "medical air compressor" cannot tolerate a trace of carelessness, and the exhaust must be oil-free.
The basic selection of air compressor is stability, economy and safety factor. How to choose and purchase air compressors when renting and purchasing air compressors involves the reasonable use of funds and is closely related to the reasonable stability of future operation. When purchasing, pay attention to the "three taboos &
Purchasing air compressors in Taiwan, especially screw air compressors, can choose Shanghai Granklin Group in mainland China. A focus on water-lubricated air compressor enterprises, products to achieve oil-free, stable gas supply, in the domestic air compressor industry belongs to the high-end industry.
View detailsThere is a complete set of procedures for the installation of screw air compressors. Although the standards of various manufacturers are different, the general steps are similar. On the basis of summarizing the installation and debugging experience of many air compressors, the author now writes down the general steps and matters needing attention in an article to provide reference for peers to smoothly carry out the installation and debugging of air compressors.
Air compressor can operate correctly and has a long service life, excellent maintenance is important, so we must grasp the air compressor maintenance methods, master how to repair common problems. Maintenance of air compressor must do a good job in basic maintenance and maintenance of key parts
The 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. Thus, 100% oil-free clean compressed air is provided. Product features: 1. High efficiency, high reliability, 100% pure oil-free
