subject: Electric Slip Ring (brush) The Maintenance Of Component Of Brush Rocker Join Wants A Place [print this page] When be safeguarded of industrial generation set daily and be being overhauled, the rotor in part of electric slip ring, brush is maintenance often component. This and we use medium maintenance to having close connection at ordinary times, need to add an attention more in working at ordinary times so. To a few big generation set, the scheduled maintenance that reachs electric slip ring every year to aircrew and be being safeguarded daily is crucial, what this affects facility is normal move, the respect such as moving efficiency, safe production.
A lot of power companies are annual commonly the overhaul, 5-8 year undertake big maintenance. Long moving position can accumulate element of a lot of breakdown to whole system. Part of the electric slip ring in aircrew, brush often can appear a lot of problems. In old practice experience, we summed up a lot of experience and countermeasure. The brush rocker of electric slip ring needs to do the blemish of insulation property to detect normally, if insulation resistance reachs communication,compression function reduces demonstrative insulation property to had been put in the risk. Because electric slip ring leaks in the long-term oil head in running,main reason is oil and the dust pollution that brush attrition produces the surface of insulating material and the insulation property that bring about drops, the ruinous very big and very difficult eliminate that its produce to electric slip ring.
The maintenance of component of brush rocker of electric slip ring, the carbon brush that general power company uses is used dog advancedly constant voltage is brushed grasp, can make be in the overhaul is the link that discharges tone bedspring pressure. But the fatigue and unusual position that should notice bedspring loses spring. Once this kind of phenomenon happens to be able to create pressure insufficient and the contact that cause is undesirable, the likelihood causes phenomenon of strike a light to be injured to slip ring surface. So the fatigue phenomenon of bedspring needs to pay close attention in overhauling a process.
The temperature below the working status of the electric slip ring of aircrew is commonly control in 50 , once temperature happening is unusual, the likelihood is blemish of generation of interior spare parts. Need staff member adds an attention more at ordinary times, so that try in time,handle. Still need to defend the in-house structural member of electric slip ring regularly, roll did not block block from time to tome, insulation component is polluted to wait. Basically go to detail only, make blemish all be in the overhaul is to eliminate, ability gets aircrew move steadily for a long time.
