外文资料翻译jaw crushers common malfunction and its remedythere will appear a variety of failure in jaw crushers daily use ,here we list some common faults and their remedies:jaw crusher common symptom1:a suddenly stop of the host (commonly known as: boring car).reasons:1)the block of discharge port lead the sealing; 2)the loose of rotation of the belt driving sheave rotating make the belt slip; 3)eccentric shaft bush sleeve is loose, causing the rack bearing no gaps in both sides, so that the eccentric shaft stuck, unable to turn; 4)workplace voltage is too low, which causes the host encounter aniseed,and the inability broken; 5) bearing damage.remedy:1)removing obstruction of the discharge opening to ensure the smooth flow of materials; 2)tighten or replace belt; 3)to re-install or replace the bush sleeve; 4)align the workplace voltage to conform to the requirements of the host operating voltage; 5)replacement bearing.symptom 2:the host sheave and moving jaw functioning normally, but broken cease work. reasons:1)tension spring break; 2)rod fracture; 3)off or broken of the bracketremedy:1)replace tension spring; 2)replace the rod; 3)to re-install or replace the bracketsymptom 3:stunned crusher spring break. reason: emphasis on small jaw crusher discharge opening with the spring tention. remedy: replace the spring.symptom 4:flying sheave shaft swing. reasons:1) flying sheave shaft hole slot, flat key or shaft wear and loose in coordinating; 2)stone rolling into the inside of the wheel result in cracking of the flying sheave wheel shell; 3)casting defects; 4)flying sheave expansion sleeve looses. remedy:1)flat key wear, replace the flat key, or replace the eccentric shaft or fly wheel slot; 2)by doing flying tank round shield and replace the eccentric shaft or fly wheel slot; 3)replace the eccentric shaft or tank round. 4)re-tight set up sleevesymptom 5:there is beating and crash sound in the process of moving or fixing the jaw plate . reasons:1)fastening bolts of jaw crushers jaw plate loose or falling; 2)jaw crushers discharge opening is too small lead the bottom two jaw plates hit each other. remedy:1)fixed or installed for tight bolts; 2)align the nesting population to ensure that the correct gap between two jaw plate.symptom 6:the fracture of bracket.reasons: 1)jaw crusher host overload or materials whose size is greater than the size of feeding mouth enter in; 2)non-broken material enter the crushing chamber; 3)its not parallel between toggle and toggle pad and skew exists; 4)jaw crusher castings appear more serious casting defects.remedy: 1)replace the toggle and control the size of the feed, and prevent overloading the host; 2)replace the toggle and take measures to avoid non-broken material entering the crushing chamber; 3)replace the toggle and the worn toggle pad, install the toggle correctly; 4)replace into qualified toggle.symptom 7:adjusting toggle seat broken. reasons: 1)they purchase or restructure of the toggle and toggle pad themsrlves,which does not meet the design requirements of oems; 2)fixed bolts of the adjusting toggle seat loose; 3)there are serious casting defects or welding defects of the adjusting toggle seatremedy: 1)replace the adjusting seat and replace into oems original assembly bracket, bracket pad; 2)replace the adjust seat and tighten the adjust seat bolt; 3)the replacement of the adjusting toggle seat.symptom 8: the temperature of the frame axle-bearing or in the movable jaw is too high. reasons: 1)lack of grease; 2)grease stains; 3)bearing clearance is not suitable or the bearing contact is not good; 4)bearing damage.remedy: 1)by adding the right amount of grease; 2)cleaning the bearings and replace grease; 3)adjust bearings tightness or trim the bearing and bearing pad in the use of pads; 4) the replacement of bearingssymptom 9; rear of the rack produce percussion sound. reasons: 1)the rod is not tighten, the bracket hit the movable jaw and the toggle plate of the adjust seat pad; 2)friction exists between the rod and the lower jaw hook; 3)the spring and spring seat strike each other. remedy: 1)fasten the rod; 2)check whether the spring tension is valid or not,if not replace the spring,tighten the rod and re-tighten the spring; 3)install the spring seat and tighten the nut of the rod to the right position.symptom 10: jaw crusher frame serious beating. reasons: 1)anchor bolts loose or broken; 2)balance weight block of the flying sheave deviate its position; 3) the host without solid foundation and isolation measures. remedy: 1)tighten the anchor bolts or replace broken bolts; 2)remove the cover plate fly wheel slot, loosen the fly wheel slot expansion sleeve bolts,adjust the position of the flying sheave balance weight block, then tightening up expansion sleeve bolts; 3) reinforce base, padded sleepers or rubber, etc.取颚式破碎机的常见故障及其补救有颚式破碎机的日常使用中会出现各种各样的故障，我们在这里列出一些常见故障及其补救措施：颚式破碎机常见symptom1：主机（俗称：闷车）突然停止。原因：1）卸货港块导致的密封; 2）带传动滑轮旋转旋转松动的皮带打滑; 3）偏心轴套套松动，造成机架的轴承在双方没有差距，所以偏心轴卡住，无法打开; 4）工作场所的电压过低，导致主机遇到大料，无法打破; 5）轴承损坏。补救措施：1）消除梗阻的开放，以确保物畅其流的排放; 2）拧紧或更换皮带; 3）重新安装或取代布什袖; 4）将工作场所的电压符合要求的主机工作电压; 5）更换轴承。症状2：主机滑轮和动颚运转正常，但破碎的停火工作。原因：1）张力弹簧断裂; 2）连杆断裂; 3）关闭或支架破裂补救措施：1）更换拉簧; 2）更换杆; 3）重新安装或更换支架症状3：目瞪口呆破碎春假。原因是：重点小型颚式破碎机排料口与弹簧张力。补救措施：更换弹簧。症状4：飞滑轮轴摆动。飞行滑轮扩大的原因：1）飞滑轮轴孔槽，平键或轴磨损和松散的协调; 2）石头滚动到内轮结果在飞行滑轮轮壳开裂; 3）铸造缺陷; 4）套松动。补救措施：1）平键磨损，更换平键，或更换偏心轴或飞轮槽; 2）通过做飞行坦克轮盾和更换偏心轴或飞轮槽; 3）更换偏心轴或槽轮。 4）再紧定套症状5：有殴打和碰撞过程中的移动或固定颚板的声音。原因：1）紧固螺栓的颚式破碎机的颚板松动或脱落2）颚式破碎机的排料口过小导致的上下两颚板击中对方。补救措施：1）紧螺栓固定或安装; 2）调整排料口，以确保正确的两颚板之间的差距。症状6：支架断裂。原因：1）颚式破碎机主机超负荷或材料的大小是大于喂食口进入的大小; 2）非破碎物进入破碎腔; 3）它是不切换和切换垫和歪斜之间的并行; 4）颚式破碎机铸件出现更严重的铸造缺陷。补救措施：1）更换切换和控制饲料的大小，防止超载主机; 2代的
