大型挖沙船挖斗维修保养方法有哪些？

   挖沙船可分为单传送挖沙船、双传送挖沙船、三传送挖沙船、四传送挖沙船，挖沙船的保养刻不容缓，有的客户认为保养是件无所谓的事，其实不然，表面觉得保养没有必要，如果长期进行保养，会使设备不容易老化，使用寿命时间长，对各个部件也要进行定期维护保养，有的客户会进入误区，在选择润滑油时，会认为用同一型号的，这是错误的，因为挖沙船的型号是不同的，所以在选择润滑油时，也要用不同型号的润滑油，在保证质量的前提下还要进行压缩比和排量进行选择，最后选出最适合自己挖沙船的润滑油。那么，挖沙船挖斗是如何维修保养的。
  按时间来进行保养：
  每100H保养项目；动臂脚销；动臂缸缸杆端；动臂、斗杆连接销；斗杆缸缸杆端；挖斗缸缸头销轴；半杆连杆连接销；动臂缸缸头销轴；斗杆、挖斗缸缸杆端；挖斗缸缸头销轴；斗杆缸缸头销轴；斗杆连杆连接销；检查回转机构箱内的油位（加机油）；从燃油箱中排出水和沉淀物。
  每250H保养项目；检查终传动箱内的油位（加齿轮油）；检查蓄电池电解液；更换发动机油底壳中的油，更换发动机滤芯；润滑回转支承（2处）；检查风扇皮带的张紧度，并检查空调压缩机皮带的张紧度，并作调整。
  每500h保养项目；同时进行每100和250H保养项目；更换燃油滤芯；检查回转小齿轮润滑脂的高度（加润滑脂）；检查和清洗散热器散热片、油冷却器散热片和冷疑器散热片；更换液压油滤芯；更换终传动箱内的油（仅首次在500h时进行，以后1000h一次）；清洗空调器系统内部和外部的空气滤芯；更换液压油通气口滤芯。
　以上是统一重工为您介绍的挖沙船挖斗的维修保养步骤，按照以上操作，相信您的挖沙船会越来越好，在使用过程中，如果发生故障，请不要焦躁，分析原因并找到解决方法。希望会对大家有帮助。

Large dredger bucket maintenance methods are there?
   Dredging vessels can be divided into single and double transfer transfer dredging vessels, dredgers dredging vessels, three transport four transfer dredging vessels, dredgers maintenance urgent, some customers think that maintenance is a matter of indifference, in fact, there is no need to feel the surface maintenance, if long-term maintenance, the equipment is not easy to aging, the use of the life time is long, the various components should be regular maintenance, some customers will enter the misunderstanding in the choice of lubricating oil, will think with the same type, this is wrong, because the dredging type is different, so in the choice of lubricating oil, lubricating oil should also use different types of. On the premise of ensuring the quality and compression ratio and flow rate were selected, the final selection of the most suitable for their own dredging lubricating oil. Then, the dredging bucket is how to repair and maintenance.
Maintenance by time:
   Each 100H maintenance projects; boom foot pin; boom cylinder rod end; the arm and the bucket rod connecting pin; the bucket rod bucket cylinder rod end; cylinder head pin; half rod connecting pin; the boom cylinder head pin; bucket rod and bucket cylinder rod end; bucket cylinder head pin; the bucket rod cylinder head pin; the bucket rod connecting pin; oil level check box rotating mechanism (with oil); water and sediment discharge from the fuel tank.
   Each 250H maintenance projects; final drive oil level check box (add gear oil); check the battery electrolyte; replace the engine oil pan oil filter replacement engine; lubricating rotary bearing (2); check fan belt tension, and check the air conditioning compressor belt tension, and make adjustments.
  Each 500h maintenance projects; at the same time every 100 250H and maintenance projects; fuel filter replacement; check rotary pinion grease height (grease); check and clean the radiator radiator, oil cooler heat sink and chiller heat sink; replacement of hydraulic oil filter replacement; final transmission box oil (only for the first time in 500h, 1000h a); air filter cleaning device of air conditioning system of internal and external; replacement of hydraulic oil vent filter.
   The above is to introduce you to the unified heavy dredging ship maintenance steps digging bucket, operate in accordance with the above, I believe your dredgingship will become better and better in the use process, if a failure occurs, please don't fret, analyze the causes and find solutions. I hope it will be helpful.
