Machine of decelerate of AQC furnace 2 # zipper machine fault

Machine of decelerate of AQC furnace 2 # zipper machine fault 2019 - reflection 06 - 17 but on December 11, 2018, the production line technician 2 # zipper machine can't reflect the AQC furnace puller, abnormal sound. Immediately to the site inspection found the zipper machine caton, ash conveying chain is not turn, emergency shutdown. Overhaul found: zipper machine chain, drive chain, reducing motor keyway is normal, the deceleration motor 10, to replace the new online products. Tighten the zipper machine chain, not the trial run. Suspect that the chain has a card and product material, ready to clean the concave in deformation wear resistant lining board. When high attenborough said check drive chain has a problem, wear too long and need to change, three line 2 machine all say three line without the chain, can only find from the other line, I found two drive chain, in the machine room Yang Cong ready to pack, but high and reflect the new and old chain length, the old chain is too long to discharge a clasp, support his argument. Back pack good after unloading button 1, Yang Cong went to operator month trial run, but high and arrange release Liao Zhikun deceleration machine base. After fastening good drive chain, high pressure and speed reducer base of loosen bolts in tension adjustment, maximize the use of base that drive chain is too loose, not the final adjustment, tighten the anchor bolts, boot start-up, normal operation. After empty 2 # zipper machine product material, will arrange Yang Cong wear-resisting lining part of the casing deformation concave cutting, it is running. Review: 1, the 9th of this month the AQC furnace 2 # zipper machine speed reducer for oil processing speed mechanical and electrical machine sliding sideways serious problems and dismantling machine, found that the motor shaft keyway flattening, almost need to welding turning, so temporary from a second-tier old motor assembly. In 2, 10, early inspection found AQC furnace 2 # zipper machine reducer vibration sound, in the afternoon I got back to the warehouse shipment notice # for XWD7 - online type 71 - 5. 5 the cycloidal reducer of the arrival of the goods, immediately go to the warehouse inspection and get out, just get back the part assembly room appears AQC furnace 2 # zipper machine reducer strike, there will be a new reducer change quickly. 3, 11, early in the morning and AQC furnace 2 # zipper machine reducer caton strike, almost every day in this deceleration machine, have a little depressed. Reflection: 1, since the AQC furnace 1 # zipper machine speed reducer by cycloid needle rotation into hardfaced tooth, cutting deformation of box all internal concave wear resistant lining board, 1 # zipper machine reducer never seen again. 2, 2 # zipper machine of cycloidal reducer XWD7 - 71 - 5. 5 on November 26, appear serious side output shaft oil seal leakage, and to replace it with the old standby reducer after using up 10 minutes to caton, immediately will spill reducer to replace the skeleton oil seal, back pack. Check said old reducer output shaft run coat, to find a 5. 5 kw reducer base, but the output diameter of axle and structure are not the same, only to purchase a as backup. 3, 10, the old motor reducer caton check the old motor bearing damage, has been replaced, gouge surfacing keyway damage to the motor shaft is also good, has been assembled. From the experience to the problem of zipper machine in addition to check reducer, motor, and ash conveying chain, but also adjust drive chain, recently three wire power plant flue gas temperature is high, large amount of ash, chain deformation is large, should timely adjust the zipper machine tension, providing monitoring running current as well. As 11, 2 # zipper mechanical and electrical machine in the rotation, but the chain still, 1 # zipper machine and discharger is running, it is easy to cause serious plugging material damage equipment accident, researchers found that reflect was production line, not only cause major accidents. （ Source: 'coolie see cement)
