About the screw air compressor oil

About the screw air compressor oil 2019 - governance systems 08 - 14 Qian Qimen ( Double xin environmental protection equipment management department) Screw air compressor is one of the important devices in the industrial production to provide compressed air and equipment, because of the simple structure type screw compressor, price moderate, become a lot of enterprise's first choice. Screw compressor, though useful, high efficiency, but in the oil is still a headache problem, let's take a look at the spill damage: first: screw compressor oil both mineral oil and semi synthetic oil and synthetic oil, are generally very expensive, and often in the industry are own brand compressor can only use their own brand compressor oil, than get in the car with a well-known brand all about synthetic oil prices, once run oil, oil spills, added the cost of the compressor oil is a lot of overhead; Second: oil ran it doesn't matter, we'll add it begins, but core barrel of oil content of oil and gas are crushed, and long-term internal and external abnormal erosion on both sides of the air, oil, oil content inside the core glass fiber graticule is easy to damage, it is difficult to prolong service life, even the half of life is short of, frequent replacement of oil core is a lot of overhead; Third: downstream of the air handling equipment can not stand, oil containing anti-wear, antiknock, rust, stabilizer and other components, these components in the compressed air entrainment scouring under or accumulate in the downstream of heat exchange cooling equipment, continue for a long time to also is not a way to, and may damage the cooling heat transfer equipment; Fourth: compressed air only through dry, lower dew point, can be used in the back-end precision gas instrument and equipment, to ensure that it can work normally and leaking oil to run into these drying equipment, will be drier 'poisoning, and non-renewable, such not only change the desiccant will be an unbearable burden, also to end gas meter with challenge and risk. To sum up, screw machine run oil 'truculent'! So let's look at how to through several aspects to control the oil, make the oil content in exhaust control under 3 PPM and, well, the economic operation. One is the oil core quality problems. This need not say more, quality is reliable to buy the rest assured, with enjoyable. Second, the minimum pressure valve problem. Or leak of the minimum pressure valve opened ahead of schedule, so in the screw machine boot establish barrels of oil and gas pressure will become long, this kind of circumstance is in a state of low pressure gas oil mist concentration is high, through oil core flow quickly, resulting in oil core load increase, oil filter effect, result in high fuel consumption. Three is to use unqualified compressor oil. Let's now mostly screw machine has function of high temperature and self-preservation, usually stop temperature set at 110 ℃, then use the unqualified compressor oil screw machine when high exhaust temperature, the unqualified oil mist particles entrained air pressure is consistent with the gas phase molecular diameter ( Molecular diameter & le; 0. 01μ m） , to separate the oil core is difficult to capture it and results in excessive fuel consumption. Four is too much. Amount to more than the normal oil level, part of the oil with air flow away, and lead to excessive fuel consumption. So everything is not the more the better, it's best to conform to the requirements. Five is a one-way valve damage. If oil return valve damage, so in the condition of downtime, in barrels of oil and gas under the action of internal pressure is bound to a large number of compressor oil back to the oil inside the core, the next time the compressor operation, the oil core inside the compressor oil will not be back in the nose in time, thus resulting in a large number of oil ran away with the exhaust to the downstream equipment. Six is improper return pipe installation. In overhaul screw machine, return pipe was not inserted to the bottom of the oil core ( Reference: oil core arc at the bottom of the heart. 1 ~ 2 mm is better) , leading to a separate compressor oil cannot promptly returned to the nose, with empty run together and go outside. Seven is foreign bodies blocked. When the return pipe, a foreign body check valve, oil filter, such as jams, on the one hand, after separation of barrels of oil and gas, oil core cohesion at the bottom of the oil in the oil core will not be able to return to the nose, on the other hand has condensed oil droplets was blowing air, just as the airflow run away. Well, probably is here, in the hope that useful screw machine and by running oil with friends can try the above method, hope to help people in need.
