The change of oil (lubricant) temperature in Jinan air compressor will have a certain influence on the lubrication effect of air compressor oil (lubricant), thus affecting the normal operation and service life of Jinan air compressor. During the operation of products for many years, there are many equipment accidents caused by lubricating oil, most of which are due to the failure to control the oil temperature of air compressor oil (lubricating oil). Because of the instability of oil temperature, the oil quality of air compressor oil (lubricating oil) has changed.
In the daily operation process, it is found by statistics that the oil temperature of these air compressors in production is generally between 80 90 C. According to the operating principle of air compressor oil (lubricant), when the oil temperature of air compressor oil (lubricant) is less than 40 and more than 90 C, the oil quality will change.
When the oil temperature is less than 4O C, the oil viscosity is too high and the mechanical friction is blocked. At the same time, it is more dangerous to produce a large amount of carbon deposit, which will cause the equipment to burn or explode at high temperature. When the oil temperature is higher than 90 C, the oil is easy to oxidize, the viscosity decreases or deteriorates, the lubrication effect is not good, and the equipment life is poor. Life shortens. Therefore, in order to reduce equipment accidents, the air compressor temperature in Ji'nan should be controlled between 80 and 90 degrees.
Analysis of the causes of excessive oil temperature
1.1. Cause of low oil temperature.
The temperature of Ji'nan air compressor oil (lubricating oil) is below 22 C at rest. There are not many factors leading to low oil temperature, such as low temperature or high viscosity of air compressor oil lubricant itself, less number of opening equipment, low outlet pressure and so on, so that air compressor oil (lubricant) can not be fully utilized.
1.2. Cause of excessive oil temperature.
There are many factors leading to high oil temperature, which mainly occurs in summer. The main factors are: high temperature; high temperature of circulating cooling water or blockage of cooler; high outlet pressure.
Two. Control method of oil temperature of air compressor in Ji'nan
2.1. Control method of low oil temperature: low oil temperature or long-term unchanged, easy to increase friction of transmission parts, and sometimes scream, so that equipment can not be fully lubricated, causing harm to equipment. The low oil temperature mainly occurs in winter.
(1) Strengthen the sealing and heat preservation of the factory building, and control the flow of circulating water to one third of the original, so that the cooling effect of the oil cooler is reduced and the oil temperature is increased.
(2) keep 1~2 compressor running continuously for more than 3 days. The oil temperature rises naturally by mechanical friction.
