电瓶叉车突然不能升降了是怎么回事?

来源:http://www.jnhgjx.net/ 日期:2021-09-25 发布人:hangong

电瓶叉车的主要“使命”是实现货物的水平搬运、堆垛、装卸,但在使用过程中可能会出现很多问题,例如:未能实现灵活升降。 造成这种现象的原因是什么?

The main "mission" of battery forklift is to realize the horizontal handling, stacking and loading and unloading of goods, but many problems may occur in the process of use, such as failure to achieve flexible lifting. What are the reasons for this phenomenon?
桅杆开始大幅度升起时,肯定会晃动,说明气缸内有气体,可以通过多次升降负载来达到排气效果,或因液压系统漏油,检修或更换油封和液压缸。
When the mast starts to rise substantially, it will shake, indicating that there is gas in the cylinder. The exhaust effect can be achieved by lifting and lowering the load for many times, or due to oil leakage of the hydraulic system, repair or replace the oil seal and hydraulic cylinder.
当电瓶叉车开始装载时,它会向下滑动,可能是电磁、手动换向阀,异物卡在单向阀内,或密封圈内漏,油路或油路连接处漏油造成的,拆下并更换密封件,清洁阀块。
When the battery forklift starts loading, it will slide downward, which may be caused by the electromagnetic and manual directional valve, foreign matters stuck in the check valve, or leakage in the sealing ring, and oil leakage at the oil circuit or oil circuit connection. Remove and replace the seal and clean the valve block.

提升速度慢,或无法提升,可能是液压油不足,需要加液压油; 溢流阀工作压力不足,需要调整; 油泵磨损过大造成内漏,应及时更换; 液压油温度长期过高造成变质; 粘度下降,更换液压油。
If the lifting speed is slow or cannot be lifted, it may be that the hydraulic oil is insufficient and needs to be added; The working pressure of overflow valve is insufficient and needs to be adjusted; If the oil pump is worn too much, resulting in internal leakage, it shall be replaced in time; The hydraulic oil temperature is too high for a long time, resulting in deterioration; If the viscosity decreases, replace the hydraulic oil.
电瓶叉车行驶时,驱动轮位置有异响,可能是润滑油有脏物,这时候就需要更换润滑油。 如果轴承是由于过度磨损造成的,则需要更换。
When the battery forklift is driving, there is abnormal noise at the driving wheel position, which may be the dirt of the lubricating oil. At this time, the lubricating oil needs to be replaced. 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损或控制电路未断开,只需检查控制系统。
The brake system is not sensitive. It may be that the friction plate of the brake system is worn or the control circuit is not disconnected. Just check the control system.
当电瓶叉车不能前后移动时,说明电池电量不足,驱动控制微动开关松动,驱动电机系统故障,电控板烧毁,直流接触器灵敏度减少,并且制动器被锁定,只需拧紧螺丝,调整驱动轮刹车片之间的距离,及时更换零件即可。
When the battery forklift cannot move forward and backward, it means that the battery power is insufficient, the drive control microswitch is loose, the drive motor system fails, the electric control board is burned, the sensitivity of the DC contactor is reduced, and the brake is locked. Just tighten the screws, adjust the distance between the drive wheel and brake pads, and replace the parts in time.
电池工作时间短,无法充电,电池电解液不足,及时加蒸馏水或铅酸水,或因电池老化,电池电源插头松动,或电池严重损坏,更换电池即可。
The battery has a short working time and cannot be charged. If the battery electrolyte is insufficient, add distilled water or lead-acid water in time, or the battery power plug is loose due to battery aging, or the battery is seriously damaged, replace the battery.
当电瓶叉车充电器不工作,充电器不显示任何信息时,说明保险丝已熔断,如果充电器电源灯亮,说明内部保险丝开路或电阻开路,整流器损坏。
When the battery forklift charger does not work and the charger does not display any information, it indicates that the fuse has been blown. If the charger power light is on, it indicates that the internal fuse or resistance is open and the rectifier is damaged.
