华体会国际 出租运用过程中呈现了毛病影响长臂挖掘机的正常运用，影响工程的进度，那我们就需求长臂挖掘机转向毛病扫除对策：
During the rental operation of the long arm excavator, the problems affect the normal operation of the long arm excavator and the progress of the project, so we need the countermeasures to eliminate the steering problems of the long arm excavator:
1.关于卡特挖掘机转向液压缸
1. About the steering hydraulic cylinder of Carter excavator
液压缸呈现问题的现象肉眼能看到漏油，或压路机在不平的 路上行走时前轮会自动的“四处乱跑”。其主要缘由是液压缸内活塞上的油封漏油，此时应依照产品型号换上合格的油封并确保装配时高度清洁，同时保证活塞上的两个油封唇口都向外，问题即可处理。
The problem of hydraulic cylinder can be seen by naked eyes, or the front wheel will automatically "run around" when the roller is walking on the uneven road. The main reason is that the oil seal on the piston in the hydraulic cylinder leaks oil. At this time, the qualified oil seal shall be replaced according to the product model and the assembly height shall be ensured to be clean. At the same time, the two oil seal lips on the piston shall be outward, so the problem can be solved.
2.关于液压油箱
2. About hydraulic oil tank
液压油箱内的液压油应加注规则高度，同时油箱阀门开度应足够大，以防止供油缺乏。液压油牌号应按规则加注，不能不同型号 液压油混加，以免惹起油品蜕变，使抗泡性、粘度、活动性能降落， 液压油箱要坚持高度清洁，定期清洗过滤网，以防止吸油阻力过大，加剧泵和液压油缸的磨损。
The hydraulic oil in the hydraulic oil tank shall be filled to the regular height, and the valve opening of the oil tank shall be large enough to prevent the lack of oil supply. The brand of hydraulic oil shall be filled according to the rules, and different types of hydraulic oil shall not be mixed, so as to avoid oil deterioration and make the anti foaming, viscosity and activity performance drop. The hydraulic oil tank shall be highly clean, and the filter screen shall be cleaned regularly, so as to prevent excessive oil suction resistance and increase the wear of pump and hydraulic oil cylinder.
3.关于转向分配器
3. About the steering distributor
当泵油压力足够而感到打方向特别繁重时，可能是因分配器轴套磨损、阀体与阀芯不同心而呈现卡死现象;当感到方向盘转动很轻，但总是打不到头时，可能是分配器内部因磨损过度而漏油。分配器漏油是不好修理的，通常处理问题的方法是改换新的。
When the pump oil pressure is enough and the direction is very heavy, it may be due to the abrasion of the distributor shaft sleeve and the non concentricity between the valve body and the valve core, which may cause the stuck phenomenon; when the steering wheel is felt to rotate very lightly, but it is always unable to hit the end, it may be due to the excessive abrasion and oil leakage inside the distributor. It's not easy to repair the distributor's oil leakage. The usual way to deal with the problem is to replace it with a new one.
4.关于液压泵
4. About hydraulic pump
华体会国际 出租要保证给油泵足够的输入动力，定期检查油泵固定能否牢 固牢靠，皮带张紧力能否适宜，及时察看液压泵的输出压力。假如液压泵输出压力忽然降落，应停车检查，以因泵卡死或磨损烧蚀而形成更大的损失。液压泵的齿顶与壳体内孔配合间隙为0.05-0.1mm左右，轴向间隙为0.03-0.05mm左右。普通来说，齿轮泵对液压油的敏感度是不高，只需运用得当，就不容易出毛病。
First of all, ensure the sufficient input power of the feed pump, regularly check whether the oil pump is fixed firmly, whether the belt tension is appropriate, and timely check the output pressure of the hydraulic pump. If the output pressure of the hydraulic pump suddenly drops, stop the pump for inspection, so as to cause greater loss due to pump jamming or abrasion and ablation. The fit clearance between the tooth top of the hydraulic pump and the inner hole of the shell is about 0.05-0.1mm, and the axial clearance is about 0.03-0.05mm. Generally speaking, the sensitivity of gear pump to hydraulic oil is not high. If it is used properly, it is not easy to have problems.
当长臂挖掘机转向机构呈现毛病时，要察看毛病现象，确认是液压泵的问题，还是长臂挖掘机转向分配器或液压油缸的问题，然后再依据各部件的维修规范停止认真细致的维修，普通都能处理问题。
When the steering mechanism of the long arm excavator shows faults, first check the fault phenomenon to confirm whether it is the problem of the hydraulic pump or the problem of the steering distributor or the hydraulic cylinder of the long arm excavator, and then stop the serious and meticulous maintenance according to the maintenance specifications of each component, which can handle the problems generally.
The above is an introduction from Shandong Qicheng Water Conservancy Engineering Machinery Co., Ltd. to some problems encountered in the rental process of the long arm excavator. I hope it can help you. To understand more, please click http://www.dyqing.com/
