The fan bearing wear at emergency repair two or three things

Cement preheater fan drive side bearing a rendering of the wear is sudden unexpected situation, due to environmental issues, enterprises have wrong peak consumption outage time. The peak when stop, rotary kiln stop first, because of the preheater fan of rotary kiln parking demand after cooling, so the preheater fan without downtime with rotary kiln. Central control room is in the process of rotary kiln temperature, due to operator's mistake, will fan smooth system closed, and the temperature control system was closed at the same time. Fan bearing operating temperature could have been present alarm in 60 ℃, 75 ℃ automatically jump stop, because the cause of the temperature control system is closed, the fan drive side bearing under the conditions of no oil, no temperature control maintenance work for nearly 40 minutes. After being enterprise the researchers found that the central control room, bearing once complete ablation, smoke was pouring from the enterprise, belongs to the accident with serious irregularities consumption. Sauvy industrial carbon nanometer polymer repair technology is how to complete the scene emergency repair the fan bearing a? （ 1) Sauvy industrial engineers communication equipment with the enterprise managers to stop, first understand the parameters of the equipment, such as bearing type, the diameter of the shaft, wear width, wear depth and shoulder size and the corresponding pictures; The fan bearing wear ( 2) Sauvy industrial fan shaft for repair of the equipment repair technology is adopted, there are a large number of the fan shaft and data, and with a scrap of sauvy company of tooling, once the enterprise emergency repair compare, can first choose the suitable equipment to the site, and practical measurement tooling requirements by individual data size, in conjunction with the enterprise only needs 3 hours time can complete waste tooling processing work, ensure high efficiency, high quality. （ 3) Tooling is completed, the next step of the repair work was very simple and efficient, simple operation steps, field application tooling and carbon nano polymer materials need only five hours time can finish repair and bearing device for tooling. Sauvy engineer on site repair the fan bearing wear detailed operation process is as follows: ( 1) Baked oil: appearance using acetylene oxygen to stop baking oil, operation time control between 10 to 15 minutes; The fan bearing wear position baked oil disposal ( 2) Exterior burnish: appearance using the polishing machine polishing rough, clean, progress sauvy carbon nano polymer SD7101H cohesive force. The whole grinding process control in 30 minutes, to guarantee the bearing a appearance each tiny parts polished clean; The fan bearing wear position grinding ( 3) Sauvy carbon nano polymer SD7101H dosage calculation, according to the calculation results in accordance with the 2-1 to reconcile SD7101H; （ 4) Harmonic average good SD7101H daub to bearing an appearance, and rapid tooling equipment in place; From harmonic SD7101H to tooling equipment in place, 10 minutes to complete the whole process; Daub sauvy SD7101H data ( 5) SD7101H natural curing after 30 minutes, stop heating curing, the curing time is 2 hours. Equipped with tooling for curing ( 6) SD7101H curing is complete, ready to heating bearing and remove the tooling work, both at the same time to stop. Tooling appearance to do a simple disposal after the end of removal, verify the size of repair, remove the appearance to the redundant data. Bearing heating to specify the temperature at the same time, the rapid device in place, locked tightly solid round nut, fixed end. Secondary treatment from the whole repair process to see, sauvy industry throughout the repair process is simple and quick, without tedious process steps and a large number of tools, but many of the details in the process of repair local demand strict control. The repair work and bearing, bearing, electrical equipment, after the end of enterprises using the dial indicator to repair after the concentricity of stopped the practice measure, repair precision meet the request of wind turbine, the fan bearing repair precision is good.
