screw air compressor exhaust temperature is generally too high oil cooler and water cooler caused by the temperature is too high, there may be sensor failure and other reasons. Some alarms can be eliminated immediately through the operation of the controller page, but sometimes the alarm of excessive exhaust temperature will appear after elimination. After checking the pressure and temperature of the inlet and outlet of the circulating water, it is felt that the index of the circulating water is within the normal range, and the alarm possibility of excessive exhaust temperature caused by the circulating water is very small. If the equipment is further checked and the color of the lubricating oil is found to be darker, it is judged that the maintenance cycle is reached. After checking the operation records on the screw air compressor, it is indeed the maintenance cycle. After maintenance, this phenomenon is eliminated.
Common reasons for high exhaust temperature in air pressure maintenance are:
1. the actual exhaust temperature is not too high
1. Inaccurate display of thermometer
2. Temperature sensor fault
3. Controller failure
4. Temperature switch fault
2. the actual exhaust temperature is too high
1, lubricating oil use time is too long
2. Wang filter element is blocked
3. Oil core blocking
4. Temperature control valve failure
5. The lubricating oil level is too low
6. The ambient temperature is too high
7. Fan motor reverse
8. The fan motor does not rotate
9. The outside of the air cooler is always too dirty
10. Serious fouling in the oil circuit of the air cooler
11. The exhaust channel of the cooler is not smooth
12. Cooling water pressure is too low
13. The cooling water temperature is too high
14. The cooling water outlet pipeline is blocked
15, oil cooler water circuit fouling serious
16. The minimum pressure valve is stuck
17. The check valve is stuck
18. The oil cut-off valve cannot be fully opened
19. Sealing failure of temperature control valve core
Air compressor is the abbreviation of "air compressor. As early as 1640 AD, the first (mechanical) vacuum pump made in Germany, now, with the improvement of technology, air compressors have been busy in all walks of life, such as food, tobacco and other metallurgy, petrochemical, chemical fiber, pharmaceutical and so on.
It depends on your application scenarios, such as medical, chemical, food, electronics, and other industries that require higher gas requirements, then the "5 cubic screw air compressor price" and ordinary "5 cubic screw air compressor price" is very different. So what is the difference between a high standard "screw air compressor" and an ordinary "screw air compressor?
Many friends want to buy "good" gas tank, good gas tank should be how to distinguish? Here are a few comments for a few points, for your reference:
Air compressor as a new era of general equipment, whenever encountered gas demand, can not be separated from its figure. Let's take a look at the application fields of air compressor with granklin air compressor! Factory Dimension
Oil-free air compressors have now been applied to pharmaceutical factories, mainly because the performance and characteristics of oil-free air compressors meet the requirements of pharmaceutical factories, oil-free air compressors have great use value in pharmaceutical factories. In the pharmaceutical factory, the use of compressors
Those engaged in the installation, transformation and maintenance of pipelines such as gas storage tanks and other pressure vessel equipment must obtain the corresponding qualification license. Units engaged in installation must have installation qualifications, install in accordance with relevant safety specifications and requirements, and be responsible for the safety and quality of pressure vessels, and strictly implement national safety standards and technical standards.
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 compressed air, ideal isothermal compression, displacement: 2.3-21.3m ³/min.
View detailsAir compressor mentioned earlier, is the air compressor, the main job is to compress gas, air compressor is divided into many kinds, let's take a look at it in the end what classification,
The greater the exhaust pressure of the screw air compressor, the more energy consumption. The sum of the use pressure, pipeline resistance loss and the pressure drop of the supporting equipment is determined as the lower limit of the rated exhaust pressure of the screw air compressor. Under normal circumstances, the diameter of the gas pipeline should be larger. In order to reduce resistance loss and achieve the purpose of reducing energy consumption in long-term operation. The greater the discharge pressure of the compressor, the more energy consumption.
How much does it cost to maintain an air compressor? There are many things to refer to for the cost of one maintenance. For example, according to the degree of maintenance, air compressor maintenance itself can be divided into large maintenance, small maintenance and medium maintenance. And different air compressor brands,
