OEC 'A3 case presentation' - Fully mechanized RMI S500 pump crankcase A3 improve abnormal loss report

OEC 'A3 case presentation' - Fully mechanized RMI S500 pump crankcase A3 improve report 2019 - abnormal consumption 05 - 26 LinChunLe ( The lean management in east god Boolean mine) （ 1) Reduce the RMI S500 pumping station failure frequency and influence the production task, efficient production time and the load rate of ascension, need the main equipment ( Fully mechanized face 'heart' - Pumping station) Stop aspects to improve. In using RMI S500 pump station as the main mining pump station, emulsion pump station 4, 3, use 1 standby, single pump flow 530 l/min, damaged 1 production strain, after more than two (2) began to produce a significant effect. 42202 fully mechanized coal face using RMI S500 emulsion pump station, overhaul crankcase six problems in 2018, large amount of damage, need to be 'whole' find fault source, or the longer it will cause loss of speed, impact load rate and single into level. （ 2) 42202 working face of RMI S500 pumping station fault contrast figure 2 times, grasp the present situation, Dismantling identification) According to the damage after dismantling situation, after the failure information collection, to refine fault types are classified. 3, to grasp the true cause, Classification analysis) Failure is due to dry grinding can be mainly divided into the oil way short of oil lubricating way, bearing quality differences often loss, aspects and so on three aspects of design flaws. 4, develop countermeasures ( Individual improve) When determining the improvement countermeasures, in the final against tease out, to oil pollution, oil pressure dynamic detection, selection of spare parts, lubrication method improvement, as the main research subject, wrote the A3 analysis to improve the report, the lean management idea is presented for maintenance and production maintenance.
