Lubricating oil of 1. pneumatics engine mixes bring about accumulate carbon
Breakdown phenomenon: ? Machine of pneumatics of stage of?0 of Qu dark blue, the former outfit lubricating oil that use manufacturer offers. Because lube price is high, the proposal is used replace oil. Replacing oil also is synthetic oil. For safe for the purpose of, preexistence the try out on machine of two small-power pneumatics is new-style synthesis is oily. When new synthesis oil uses 1500h, pneumatics machine gives out electric breakdown to call the police. Via further examination, breakdown reason accumulates carbon to cause electric machinery to flow too for pneumatics machine.
Case study: ? ?000h of sex of Song of enough of clear of of Xi of obstruct of cangue of of Gao of class of deceive of enough of clear of of Xi of Hu principle columns of a hall, till be maintained normally. Pneumatics machine is undertaken by two different working groups. Affirm via investigation, member of 2 pneumatics unit did not press machine of requirement general pneumatics complete platoon is clean, put in fluky psychology, bring about different component lube to mix bring about accumulate carbon

The entire plant that trouble of 2. pneumatics engine causes stops machine accident
Some sky midday 10:11, maintenance technician asks processing removes the limitation of a powerful person of blowdown of grey pneumatics machine. Operation personnel stops to eliminate grey pneumatics chance (go up a machine show already stopped, the examination after classics still is running) . Maintenance technician opens sound insulation lid, discovery divides cooling fan of grey empty press still moving. The announcement operates personnel, be on duty operation personnel presses emergency stop button, operation personnel cuts off power source of electromagnetism a powerful person. 10:18:00, our discovery comes loose on fire of sirocco fan fume, instantly main cut out an engine. But in 10:21 concentration controls personnel discovery is tall reserve the switch tripping operation of transformer, tall reserve the 0 foreword of transformer protection spur track shed protection to act well too. Intake air heater of two air in boiler in succession tripping operation, bring about fan successive tripping operation.
After accident happening, the examination discovers machine of the pneumatics that divide ash and electric machinery damage badly, the core of water supply pump includes serious damage, the hydraulic pressure shaft coupling of water supply pump discards as useless almost, give a few pipeline all round water pump different level attaint, lead plane plain bearing liner and axial diameter wear away.
Case study: ? Enough of iridium clear; Does protect Yao? covers unoccupied place of Huan of die young of of farsighted of Cui of サ of case ㄖ : Is deer saved?
Maintenance of 3. lead plane causes lead plane trouble not in time
Aircraft of some factory pneumatics is moving breakdown phenomenon electric breakdown appears to call the police in the process. Pneumatics machine was shut. When opening the mouth that take energy of life, discovery is stuck on pneumatics machine rotor have colloid of many light color, stick on pneumatics machine housing have object of many light color. Via test and verify, pneumatics plane existence accumulates carbolic phenomenon. After checking maintenance log, discover pneumatics aircraft had moved 8000 hours to was not maintained continuously. After undertaking clear and maintaining to pneumatics machine and its system, the decision remands pneumatics machine the factory undertakes maintaining. After manufacturer disassembles and be being checked, hair is existing and apparent wear away groove rolls in a lot of bearing the gyro wheel of orbit and air compressor, advocate the difference between ala coming back and the rotor that assist air compressor are less than a design to be worth, have wear away apparently the trace basically is mixed auxiliary rotor. Change pneumatics machine bearing, burnish tatty advocate, complementary rotor, assemble pneumatics plane again. After the power plant is assembled afresh, it is normal that test-drive moves
Case study: ? Housing fly of gourd ladle of fan of mill of coal of S of clear enough steals of Ti of Meng of neon A Chinese-style unlined garment fine?000h. Because lube already used 8000h, grain of its viscosity, impurity all does not accord with use standard with the tendency that accumulate carbon. If be used continuously, can produce pneumatics machine to bearing wears away and accumulate carbon.
Nose of 4. pneumatics aircraft accumulates carbolic case study
Machine of some enterprise pneumatics stays machine start again after 2 months, electric machinery passes electricity, the machine cannot be started, the hand moves pneumatics machine rotor dish do not move. Examine pneumatics machine and petroleum pipeline way, discovery is stuck on pneumatics machine rotor have colloid of maltose light color, there is colloid of maltose light color on bottom of oil gas bucket and oil path.
Case study: ? Ba of Yi of raise of of palm of eye of enough of clear of of boundless and indistinct of extensive of Zhai of Ji of male of unoccupied place lament of Yan Jiong of Shen of brandish of clear enough disrelishs of Yan Jing of Mu of firewood unoccupied place lament to get enough of Bian Kuang clear;
