电动叉车无法自由升降?

来源:/ 日期:2021-03-19 发布人:hangong

电动叉车出现的主要“使命”就是对货物实现水平搬运、堆垛、装卸货等操作,但在使用期间,可能出现很多问题。比如:未能实现灵活升降,对于这一现象的发生,又是因为什么问题所致使的呢?

The main "mission" of electric forklift is to realize horizontal handling, stacking, loading and unloading of goods, but many problems may occur during use. For example, what is the reason for the failure to achieve flexible lifting?
当门架开始大程度提升时,一定会出现抖动,这说明油缸内含有气体,可利用多次载重升降的方式达到排气效果。也或者因为液压系统渗油,对油封和液压油缸部分进行检修或拆换。
When the gantry starts to lift to a large extent, there will be shaking, which indicates that there is gas in the oil cylinder, and the exhaust effect can be achieved by lifting the load for many times. Or because of the oil leakage of the hydraulic system, the oil seal and hydraulic cylinder should be repaired or replaced.
当电动叉车开始载重时,出现自下滑,可能因电磁,手动换向阀,单向阀有异物卡住,或密封环磨坏出现内漏,输油管或油路接头有渗油,对密封件予以拆换,同时对阀组予以清理。
When the electric forklift starts to load, it will slide down. It may be due to electromagnetic, manual directional valve, check valve foreign body stuck, or seal ring worn out, internal leakage, oil leakage in the oil pipeline or oil pipeline joint. The seal shall be removed and replaced, and the valve group shall be cleaned at the same time.
起升速度慢,或无法起升,或许因为液压油量不足,需要添加液压油;溢流阀工作压力不足,需要调整;油泵磨损量过多而导致内漏,及时更换;液压油温度长期处于过高状态导致变质;黏度下降,更换液压油。
If the lifting speed is slow or unable to lift, it may be that the hydraulic oil is insufficient and needs to be added; the working pressure of the relief valve is insufficient and needs to be adjusted; if the oil pump is worn too much and causes internal leakage, it should be replaced in time; if the temperature of the hydraulic oil is too high for a long time, it will deteriorate; if the viscosity drops, it should be replaced.

在电动叉车行驶时,驱动轮位置发出异响,可能因为在润滑油中有脏污出现,更换润滑油。若因轴承过度磨损所导致,就需对其进行更换。
When the electric forklift is running, the position of the driving wheel makes an abnormal noise, which may be due to the dirt in the lubricating oil. Replace the lubricating oil. If the bearing is caused by excessive wear, it needs to be replaced.
制动系统不灵敏,可能是制动系统摩擦片磨坏,或控制电路未断开,检查控制系统即可。
The brake system is not sensitive, maybe the brake system friction plate is worn out, or the control circuit is not disconnected, just check the control system.
当电动叉车无法实现前进后退,说明电瓶电量不足、行驶控制微动开关松动,驱动电机系统故障,电控板烧毁,直流接触器灵敏度下降,刹车抱死。只要将螺丝拧紧、调整驱动轮刹车片间的距离、对零部件及时更换即可。
When the electric forklift can not move forward or backward, it means that the battery is insufficient, the micro switch of driving control is loose, the driving motor system is faulty, the electric control board is burned, the sensitivity of DC contactor is reduced, and the brake is locked. As long as the screw is tightened, the distance between the brake pads of the driving wheel is adjusted, and the parts are replaced in time.
电池作业时间短,无法充电,电池电解液不足,及时添加蒸馏水或铅酸水,也或者因为电池老化、电池电源插头松动、电池严重毁坏,这些只要更换电池就好。
Due to the short operation time of the battery, the battery can not be charged, the electrolyte of the battery is insufficient, the distilled water or lead-acid water should be added in time, or the battery is aging, the battery power plug is loose, and the battery is seriously damaged, so long as the battery is replaced.
当电动叉车的充电机不工作时,且充电器并未显示任何信息,说明熔断器已烧断。若充电器电源灯亮,内部熔断器断路或电阻式断路,整流管毁坏。
When the charger of the electric forklift does not work, and the charger does not display any information, it means that the fuse has been burnt out. If the charger power light is on, the internal fuse or resistance circuit breaker will be broken, and the rectifier tube will be damaged.
