叉车的部件故障维修保养有方法

来源:https://www.jnhgjx.net/ 日期:2023-02-23 发布人:

用吊车吊出叉车发动机,先取出变矩器,再拆出整个叉车变速箱。在拆开之前需先放完叉车变速箱油,再开始拆出波箱上盖,拆出叉车供油泵并检查有没有损坏。再取下前后档离合器总成,检查有没有损坏和磨损等情况,需要更换的必须要更换新件。再检查和清洗,然后再按顺序来安装好变速箱,再安装到叉车上。济南二手叉车厂家认为,其具体故障维修可参考以下方法:
Lift out the forklift engine with a crane, take out the torque converter first, and then remove the entire forklift gearbox. Before disassembling, it is necessary to drain the gearbox oil of the forklift first, then start to remove the upper cover of the gearbox, remove the fuel supply pump of the forklift and check whether it is damaged. Then take down the front and rear clutch assembly and check whether it is damaged or worn. If it needs to be replaced, replace it with a new one. Then check and clean, and then install the gearbox in sequence, and then install it on the forklift. Jinan second-hand forklift manufacturer believes that the following methods can be referred to for specific troubleshooting:
1、变矩器故障部分:
1. Torque converter fault part:
1)叉车发动机转速下降,处理方法是提高发动机转速;
1) When the engine speed of the forklift decreases, the treatment is to increase the engine speed;
2)油中存在气泡,直接检查管路密封性及叉车液力油是否变质;
2) If there are bubbles in the oil, directly check the tightness of the pipeline and whether the hydraulic oil of the forklift is deteriorated;
3)油温升的过高或过低。
3) The oil temperature rises too high or too low.

2、变速箱部分:
2. Transmission part:
1)摩擦片卡死或磨损,检查叉车摩擦片是否有胶,不均接触,翘曲;
1) If the friction plate is stuck or worn, check whether the friction plate of the forklift has glue, uneven contact and warpage;
2)叉车密封环或O形圈磨拓,检查密封环和槽宽是否磨拓或损伤。
2) Grind the seal ring or O-ring of the forklift, and check whether the seal ring and groove width are grinded or damaged.
3、油温过高:
3. Oil temperature too high:
1)变矩器长时间处在低速比区域工作,变矩器效率很低,或处在失速状态时间过长,应改变这种工作状况和注意避免上述工作状况。
1) If the torque converter works in the low speed ratio area for a long time, the efficiency of the torque converter is very low, or the torque converter is in the stall state for a long time, this working condition should be changed and attention should be paid to avoid the above working conditions.
2)在高转速比时,单向离合器卡死,失去控制,应检查排除。
2) At high speed ratio, the one-way clutch is stuck and out of control, which should be checked and eliminated.
3)加油量太少,或系统中产生气泡,应增加油量调整排阀压力。
3) If the oil quantity is too small or bubbles are generated in the system, the oil quantity shall be increased to adjust the discharge valve pressure.
4)油的质量不合格,应更换新油。
4) If the oil quality is unqualified, replace it with new oil.
4、变速箱部分:
4. Transmission part:
1)离合器障碍,检查摩擦片是否打滑;
1) Clutch obstacle, check whether the friction plate slips;
2)轴承损坏,检查配合面是否损坏。
2) If the bearing is damaged, check whether the mating surface is damaged.
5、变速箱不工作:
5. Transmission does not work:
1)检查操纵阀是否有弹簧卡死及断裂;
1) Check whether the spring of the control valve is stuck or broken;
2)检查主油压是否正常,如不正常检查三联泵是否磨损过大或损坏;
2) Check whether the main oil pressure is normal, and if it is abnormal, check whether the triple pump is excessively worn or damaged;
3)如主油压正常检查离合器油压如不正常检查密封环或O型圈是否磨损或损坏.检查离合器及离合器活塞环是否损坏;
3) If the main oil pressure is normal, check the clutch oil pressure. If it is abnormal, check whether the seal ring or O-ring is worn or damaged. Check whether the clutch and clutch piston ring are damaged;
4)检查变矩器油压是否正常如不正常检查变矩器。
4) Check whether the oil pressure of the torque converter is normal. If not, check the torque converter.
