q入冬季以来Q虽然多数华北和东北地区的挖掘机用户已经开始进入“冬季休整期”,但是仍然有一部分讑֤奋战在工CQ在低温天气中,对设备的考验会比往常更加严Pq个时候,如何更好的操作和l护好设备,成ؓ摆在每位用户和操作手面前的问题,但是Q因为各U各L原因Q很多操作手Ҏ掘机保养q不熟悉Q日常的一些习惯也往往存在误区Q长旉下来Q往往对设备造成了损伤,那么在冬季施工时Q挖掘机的保d在哪些误区呢Q这些错误的保养习惯会给挖掘机带来怎样的损宛_Q?br /> <strong>    错误做法一Q放水过早或不放冷却水可引发的严重后果:发动机机体胀裂或骤羃出现裂纹</strong><br />     熄火前以怠速运转,待冷却水温度降至60℃以下,水不烫手Q再熄火放水。若q早放掉冷却_Z在温度较高时H然受冷I气侵袭会生骤~,出现裂纹。放水时应将Z内残存的水彻底排出,以免其结冰膨胀QZ胀裂?br />   <strong>  错误做法二:随便选用燃a可引发的严重后果Q降低发动机寿命Q损坏几率增加</strong><br />     冬季低温使柴油的动性变差,_度增大Q不易喷散,造成雑֌不良Q燃烧恶化,D柴a机的动力性和l济性能下降。故冬季应选用凝点低和发火性能好的L沏V一般要求柴Ҏ的凝点应低于本地当前季节低气?-10℃?br />  <strong>

冬季Q有的驾驶员够快速启动柴ҎQ常采用无水启动(先启动,后加冷却?的非正常启动Ҏ。这U做法会Ҏ器造成严重损害Q应止使用。正的预热Ҏ是:先将保温被罩在水׃Q打开放水阀Q向水箱内连l注?0-70℃的清洁软水Q用手触摸放水阀出的水有烫手感觉时Q再关闭放水阀Q向水箱灌入90-100℃的清洁软水Qƈ摇{曲uQ各运动g得到适当预先润滑Q然后再行启动?br />

另外Q柱塞弹、气门弹和ha器弹由于“冷脆”也Ҏ断裂。故冬季柴a机启动着火后Q应以低中速空转几分钟Q等冷却水温度达?0℃时Q再投入负荷作业。错误做法七Q不注意Z保温可引发的严重后果Q降低工作寿命,损伤发动?br />     冬季气温低,Ҏ使柴Ҏ工作时冷却过度。故保温是冬季用好柴Ҏ的关键。在北方地区Q冬天用的柴a机都应配备保温套和保温帘{防寒设备。另外节温器ҎҎ工作时的升温L重要作用。故入冬前应查节温器的工作是否正常,失效的节温器应及时更换?br /> <br /> 挖掘机维修保养,挖掘机动作慢Q挖掘机无力Q挖掘机液压늻修找立特松挖掘机修理厂更专业?br /></p><br /> </div> <div
