颚破l修要点Q颚式破机大、中、小 3 个维修时期的l护要点Q向故障说拜拜~

颚式破碎Z为制砂生产线?“第一道关卡”,常年在高负荷、高_尘环境下运行,故障停机 1 天就可能造成C元损失。某砂石厂通过严格执行大中修制度Q将讑֤故障率降?60%Q用寿命g长至 8 q以上?strong>颚破l修要点的精准把握,是设备持l稳定运行的核心(j)保障。?/p>

颚式破碎机是制砂生U中不可或缺的破设备,׃其破工作的生环境恶劣Q用时间久?jin)运行时q可能经常出现各U故障。ؓ(f)?jin)保证颚式破机讑֤的稳定运行,提高讑֤性能Q日常的l护保养工作很重要。我们根据其l修E度的不同,可分为小修、中修和大修Q下面给大家介绍q三个维修阶D늚内容Q?/p>

一、小修:(x)日常保养?“防U(k)?/h3>

  1. 核心(j)l修内容?/li>
  • 调整装置(g)查:(x)重点(g)查楔块调整机构的杄度,保排矿口间隙符合生产要求(如处理花岗岩Ӟ间隙应控制在 10-30mmQ,每调整一ơ需锁紧螺母Q防止松动。?/li>
  • 易损件更换:(x)(g)查颚板(动颚与定颚)(j)的磨损情况,当单边磨损量过原厚度的 1/3 Ӟ?200mm 厚颚板磨损至 130mm 以下Q,需?qing)时更换Q推力板若出现裂U,即未完全断裂也必须更换Q避免断裂后损坏机架。?/li>
  • 润滑pȝl护Q清za(b)杯和油管Q更换润滑a(b)Q徏议用 320 h压轮a(b)Q,加a(b)量以Ҏ(gu)轴颈 1/3 为宜Q每月检查一ơa(b)位,不时及(qing)时补充。?/li>
  1. l修周期与效?/strong>?/li>

修周期通常?15-30 天,具体可根据物料硬度调_(d)如破玄武岩时羃短至 20 天)(j)。某生UK过严格执行修Q将颚板更换周期?3 个月廉?4.5 个月Q单ơ维修成本降?20%。?/p>

二、中修:(x)性能恢复?“关键”?/h3>

中修需在小修基上,Ҏ(gu)?j)部件进行深度检修,恢复讑֤主要性能参数。?/p>

  1. 核心(j)l修内容?/li>
  • 늛修全部目Q重点处理结构性磨损:(x)?/li>
  • 轴类部gl护Q检查偏?j)u的径向蟩动(应≤0.05mmQ,若超差需q行车削修复Qu瓦间隙若过 0.3mmQ需重新铸巴氏合金q研,保接触面积?70% 以上。?/li>
  • 拉杆与弹检修:(x)拉杆螺纹若出现滑丝需更换Q弹弹性减弱(如自由长度羃?5% 以上Q时必须更换Q防止破时产生剧烈振动。?/li>
  • 机架(g)查:(x)用水qA(g)机架水q_Q偏差≤0.1mm/mQ,发现变Ş需q行矫正Q必要时加固焊接。?/li>
  1. l修周期与案?/strong>?/li>

中修周期一般ؓ(f) 1 q_(d)处理岩的设备可~短?8 个月。某颚破因未?qing)时中修Qu瓦磨损导致偏?j)uq热Q被q停?3 天,l修费用?5 万元Q规范中修后Q同c问题未再发生。?/p>

三、大修:(x)讑֤重生?“手术”?/h3>

大修是对讑֤q行全面LQ适用于运?3-5 q_(d)或篏计作业超 10000 时Q的讑֤Q可大幅廉使用寿命。?/p>

  1. 核心(j)l修内容?/li>
  • 包含中修所有项目,重点更换关键部gQ?/li>
  • 偏心(j)轴更换:(x)若u颈磨损超 0.5mm 或出现裂U,必须更换新uQ徏议选用 40CrNiMo 材质Q,新u安装前需q行动^衡测试。?/li>
  • 机架LQ对机架内壁q行L(fng)除锈Q涂刯(g)磨涂层Q如 KN17 高分子陶h料)(j)Q增强抗冲击性;(g)查地脚螺栓孔Q磨损严重时需重新M或焊接预埋板。?/li>
  • 技术升U:(x)可加装自动润滑系l(定时定量供a(b)Q、过载保护装|(如液压保险装|)(j)Q提升设备自动化水^Q降低h工成本。?/li>
  1. l修周期与收?/strong>?/li>

大修周期通常?3-5 q_(d)某老设备经大修后,处理量从 100t/h 提升?120t/hQ能耗降?15%Q? q内收回大修成本q实现额外收?30 万元。?/p>

l修注意事项?/p>

  • l修前必L?sh)ƈ?zhn)挂 “禁止合闸?标识Q进入破腔(g)查需pd安全l뀂?/li>
  • 易损件徏议选用原厂配gQ如颚板、推力板Q,虽成本高 10%-20%Q但寿命是副厂g?2-3 倍。?/li>
  • 建立l修台̎Q记录每ơ维修的部g、更换时间及(qing)q行参数Qؓ(f)下次l修提供依据。?/li>
