【正文】 , guide the state overhaul and implementation of a science equipment management.(3) thermal power coal condition maintenance is based on maintenance plan based on technology, such as maintenance records, drawings and technical training and post standard and other basic management work, condition maintenance has been further application. Such as the state overhaul Ann lending standards change and maintenance file bag standardization, repair dangerous point prediction and evaluation standard, the state overhaul project plan, prepare, and acceptance, missioning standardization, etc., the standardization of equipment to carry out the state overhaul, maintenance, production safety prehensive pointed to improve the efficiency of maintenance and repair quality, improve equipment reliability work is reliable guarantee.(4) high quality inspection personnel condition maintenance is the key to success. The state overhaul to maintenance staff technical quality requirements mainly embodied in three aspects: one is to be able to master the condition monitoring and fault analysis method, prehensive evaluation of equipment state of health。The second is to participate in maintenance decision, can work out the optimized maintenance plan and maintenance process。 Three is a rich maintenance experience and superb inspection repair technology, do good repair required.(5) coal SPC reform, industrial TV, multimedia call system and other advanced monitoring, diagnosis and analysis technology and equipment is implement the state overhaul of necessary means. Implementation of the equipment state inspection, must strengthen the state overhaul of technology organization, information of the ensemble joint application, technology improvement work management and coordination.(6) coal equipment state inspection must adhere to the safety first thought, to follow the principle of benefits as the center, in the implementation of,According to certain scientific laws, both must maximize equipment utilization, also want to prevent blind extended maintenance interval causeEquipment overhaul, and at the same time in the configuration program control and advanced technology and equipment, according to their own objective conditions, do the full technical and economic analysis.Second, the implementation of the coal the state overhaul of contentThe implementation of the state overhaul not just detection, analysis, diagnosis, prediction and maintenance decisionmaking, implementation and maintenance maintenance evaluation, andRelating to the operation, management and technology integrated, and therefore, the implementation of the coal the state overhaul of basic contents :(1) perfect maintenance management system and repair technology standard. Such as: coal equipment state inspection management system, coal equipment inspection system, coal equipment reliability management system, staff at all levels of the post responsibility system, coal equipment state inspection testing technology process standards, etc.(2) coal equipment present situation investigation. Do the state overhaul must understand coal system layout and equipment parameters, understand coal equipment operation and maintenance of the basic situation, understand coal equipment maintenance and the state overhaul of expectations. Coal equipment to turn dynamic wear parts is given priority to, doing good equipment tendency management, grasp the equipment degradation law, judge equipment safety degree, thus take preliminary control measures, such as car dumper orbit deformation, belt machine coal drop tube wear, belt clad surface wear, bucket turbine wheel wear, steel wire rope wear, coal groove wear of precontrol measures.(3) maintenance personnel training. Coal as soon as possible the state overhaul can get the key to success is to let all of the maintenance staff understand its the basic principle and contains process, it must be through the serious training, maintenance decision, maintenance management, technical implementation, technology evaluation to plete, especially for leadership, management personnel and technical personnel training.(4) evaluation system. Evaluation of the existing operation and management system, and find out the suitable for the state overhaul part will evaluate get article technology requirements, specifications listed, and puts forward the requirements of the existing system integration, forming a fixed maintenance mode, and be programmed standardization.(5) reliability evaluation. Equipment reliability evaluation purpose is to determine coal equipment maintenance of the key factors, from the cost and benefit safety(6) maintenance evaluation and optimization. Through summarizing the successful repair experience and unsuccessful lessons, analysis maintenance strategy and current party the advantages and disadvantages of method, and improve and implement new maintenance strategy, which is to repair job evaluation to the core target.(7) support the implementation of the technical system. According to the coal equipment running status, installation lock, rope, plugging coal, coal flow, coal bits,skid and measuring element, for transport coal SPC system and industrial TV monitoring system, achieves the equipment reliability testing and analysis, to shape state maintenance provide support.Three, power plant coal dust removal method of the systemThe power plant coal system according to the nature of the dust source selection management is used mostly or dust, sealing dust, dust three ways, general three bined way.(1) dust suppression. Dust suppression is rely on physical method, will stick in the coal dust still control the delivery of raw coal, make its nonproliferation or float in the sky, restraining the monly used method is spray, dust of the coal meet water increase moisture after, can the dust particles sticking to the float in the sky, another floating in the air dust, meet
