The hydraulic catch wheel maintenance procedures and matters needing attention

Hydraulic gear wheel maintenance procedures and matters needing attention - 2019 03 - 27 Wang Zhanguang ( Jiaozuo strong cement) Catch wheel there are three kinds of form, the signal block, hard gear, hydraulic gear wheel, because now the precalcining kiln are hydraulic gear wheel, so only talk about hydraulic gear wheel repair method and the matters needing attention. Hydraulic gear wheel is a control device for kiln string move up and down. With that, the kiln can easily under artificial control to realize the string up and down, to ensure belting leather mobile wheel (full width scope, achieve the purpose of the uniform wear, also can set the kiln running in a certain location; As a result of the driving force for the string up and down, no longer by skew roller kiln, is beneficial to ensure kiln around the center line of the normal operation, to reduce the additional load, etc. So maintenance, maintenance, good catch wheel, to improve the service life of rotary kiln and its components as well as the furnace refractory material life. The following simple personal opinions about catch wheel method of maintenance and repair, for peer reference. A, the constitution of the catch wheel, hydraulic gear wheel by catch wheel shaped like mushrooms, guide shaft ( 2 the root) , wear on the guide shaft, hollow shaft, hydraulic cylinder, piston, self-aligning and thrust bearing, bearing and hydraulic station, etc. In order to guarantee belting leather and axle can contact to each place, generally every day catch wheel kiln was achieved by belting leather string move up and down once or twice, but also guaranteed the normal wear and tear, size of the gear to avoid wheel, small gear grinding out the steps. Can be seen from the composition of the catch wheel, in addition to bearing are permanent parts, so catch wheel repair to check or replace the bearing. Second, catch wheel maintenance and matters needing attention in wheel is simple, because of the kiln and the confidential relationship, located in the kiln, the weight is bigger, position is higher, and between the big gear ring and belting leather, local narrow gorge, relative difficulty increases a lot. The following description about the catch wheel maintenance procedures. 1. Maintenance plan, first clarify check maintenance content, namely maintenance technical preparations. 2. Push the kiln to the upper during cold kiln, to make larger disassembly and installation space. 3. System pressure, dismantle the hydraulic piping and electrical limit to open and maintain a good, and plugged in and out of the oil hole to prevent foreign matter into the hydraulic cylinder, but also on the catch wheel stand around the play is written well, in case to find is used. 4. Play a base set wedges, pull out the pin, remove the anchor bolt. 5. The catch wheel device with chain hoist, jack gradually migrated to convenient to the location of the crane lifting. 6. Put away tie in maintenance, cleaning materials and remove the tool. 7. The catch wheel device with the crane to the maintenance, stable on the tie. 8. Clear the oil on the catch wheel device, and proper cleaning. 9. Dismantling the fittings on the catch wheel, lifting gear wheel, during lifting to knock while living, to prevent injury or damage. 10. Catch wheel hoisted out after the examination of the cleaning, check the main contents include: whether the bearing clearance inspection, bearing raceway, bearings, roller is pitting is run laps, etc. , recorded after inspection. If the check is normal, can be returned it. 11. If the inspection found problems bearing, it must be replaced. Before the change, should the new bearing clearance and other aspects of the original size for inspection, and make records. 12. Cleaning bearing and bearing housing, then pretend to bearing, thrust bearing, first put attention on tight edge, when the loose edge; Reload spacer ring; No problem after self-aligning bearing, and filled with grease. 13. Bearing installed back to catch wheel, in order to convenient to install, can to catch wheel proper heating ( Can not heat) , and then tighten fittings; If then disc wheel, flexible rotation BuKa not retained, as qualified. 14. All ready to sail, cleaning the catch wheel device on the base of oil, lifting gear wheel device, and jack, chain to be in place, according to mark alignment. 15. Tighten the anchor bolts, put on a pin, back tight wedge, beam body work. 16. The oil recovery and electrical and mechanical limit for the limit switch. If qualified, can trial judge bearing, oil, limit is normal, if no problem, clean up the scene, maintenance. Conclusion because of each gear wheel device, not the same, there are difference scheme; Reference only. Also special remind, if catch wheel wear serious, should be replaced, or you'll catch wheel and belting leather not top, additional load. Because my level is limited, each structure is different also, any errors, please correct me criticism.
