Chifeng wind power main shaft bearing of dry ice cleaning technology

Chifeng wind spindle bearing 2020 - dry ice cleaning technology 12 - 20 ( Division ring group) Xi general secretary said, innovation is the soul of a nation, is the inexhaustible driving force for the prosperity of a country, is also the most deep national endowment of the Chinese nation. To further implement the general secretary of 'innovation is the first power, under the correct leadership of party committee of division ring group, group company of the youth league, under the support of families and ring' innovators congress 'group of the youth league. Spindle dry ice cleaning 'crucial team, in the face of difficulties, clear-headed, proactive, in the section ring group alliance of innovators' innovation days' advance to eight. The team is a crucial topic with spindle clean governance, by the company engineers, combination of elite talents, power production safety equipment maintenance to a new level. The first project - - Dry ice cleaning spindle bearing chifeng wind power bearing ring group joint power, China longyuan electric, huadian tianren ring group new energy industry company such as new products, new technologies of industrial experiment and demonstration task. Since the company was founded ten years, the positive practice of building the motherland beautiful beautiful scenery line of beginner's mind and mission of northern xinjiang. 'headache technical problem caused by poor lubrication internal iron filings and loss of the chute, directly affecting the safe and stable operation of wind turbines caused economic losses. Harden oil how to sort out from the narrow bearing gap? 'with kerosene cleaning line not line? Clean with cleaner line not line? Team 'crucial research and discussion, every day in work, when you eat, the dormitory to sleep, everybody to discuss, have a good solution. Oil bearing damage harden ( A) Thrust bearing lubricating oil quality does not meet the requirements; （ 2) Thrust bearing itself bears fan pressure, the gravity of the main bearing by the impact of the larger; （ 3) Lubricating oil can not be normal, lead to bearing internal pressure is too large, cause bearing temperature is higher; （ 4) Thrust bearing material quality is not standard; （ 5) Improper assembly, main bearing, spindle and elastic support results in uneven bearing internal stress. （ 6) Poor oil discharge oil harden bearing lubrication undeserved cause damage. What is the fan main shaft bearing of dry ice cleaning? Dry ice cleaning is the use of dry ice particles in high pressure gas driven shock smeary surface, when - 78 ℃ dry ice pellets in instant impact crushing into 'ice particles into the oil layer crack moment after nearly one thousand times make the oil produces embrittlement cracking, thus to spin out the dirt instantaneous and bearing body, achieve rapid, efficient, safe, energy-saving cleaning effect. Dry ice cleaning spindle bearing advantages: 01 reduce artificial, reduce the calculation cost. 02 can thoroughly clean up the waste oil and prolong the service life of main shaft bearing. 03 of spindle bearing no damage, no residue. 04 safe pollution-free, non-toxic, tasteless. 05 cleaning cost is low, the high efficiency. Project to promote situation since the dry ice cleaning spindle bearing project, chifeng wind power company to carry out the project preparation, respectively on two high temperature experiment, grease harden serious wind turbines, the safe and stable operation of wind turbines is now half a year, the temperature information is good, the successful application of this technology for power generation equipment indicators play a role of stabilizer.
