合力叉车的大修方法及维修拆装

来源:https://www.jnhgjx.net/ 日期:2023-05-27 发布人:

合力叉车维修过程中,发动机作为内燃叉车一个很重要的部件,承担着叉车整车运转的动力来源当然,机械运转必然带来磨损,所以维修也是经常的事情。
During the maintenance process of a hybrid forklift, the engine, as an important component of the internal combustion forklift, serves as the power source for the entire forklift's operation. Of course, mechanical operation inevitably brings wear and tear, so maintenance is also a frequent occurrence.
一、将发动机从济南合力叉车上拆除,在发动机完全冷却的状态下进行,否则会引起某些机件的变形。
1、 Remove the engine from the Jinan Heli forklift and proceed with the engine fully cooled, otherwise it may cause deformation of certain components.
1、由发动机冷却系统中放出水,由发动机和液力传动中放出机油和液压油。
1. Water is discharged from the engine cooling system, and oil and hydraulic oil are discharged from the engine and hydraulic transmission.
2、卸下棚和座椅,取下散热器盖,拆离排气管消声器。
2. Remove the safety shed and seat, remove the radiator cover, and remove the exhaust pipe muffler.
3、取下脚踏板,卸下散热器、排气管及其附属装置。
3. Remove the foot pedal and remove the radiator, exhaust pipe, and their accessories.
4、拆卸发动机和液压传动与其他系统的联结件(软管、导管等)。
4. Remove the connections (hoses, conduits, etc.) between the engine and hydraulic transmission and other systems.
5、分解发动机与主传动的联接(万向节等)。
5. Disassemble the connection between the engine and the main drive (universal joint, etc.).
6、把发动机挂在起重设备上,拧下与车架连接的螺塞螺栓。
6. Hang the engine on the lifting equipment and unscrew the screw plug bolts connecting to the frame.
7、用起重设备吊起发动机,并将发动机放置在台架上。
7. Use lifting equipment to lift the engine and place it on a stand.

二、检查磨损情况
2、 Check for wear and tear
1、先看机油的颜色和品质,表面是有否有铁屑,看机油粘性。如,机油里有很多铁屑,说明要磨曲轴瓦或者连杆瓦,甚曲轴磨损。如机很粘稠,说明机油已经有很长段时间没有更换了。
1. First, check the color and quality of the engine oil, whether there are iron chips on the surface, and check the viscosity of the engine oil. For example, there are many iron filings in the engine oil, indicating that the bearing shells or connecting rod shells need to be ground, and even the crankshaft is worn. If the machine is very viscous, it indicates that the oil has not been changed for a long time.
2、在拆开连杆活塞的曲轴时观察连杆瓦和曲轴瓦的情况,如发现连被磨整个连杆不能再用,如果曲轴被磨得不是很严重则可以通过磨轴加工后再用。
2. When disassembling the crankshaft of the connecting rod piston, observe the condition of the connecting rod and crankshaft bearing shells. If it is found that the entire connecting rod cannot be reused after being ground, if the crankshaft is not severely ground, it can be reused after grinding the shaft.
3、观察气缸套的磨损情况,注意在拆开缸套时不要打到发动机的机体,防止损坏。
3. Observe the wear of the cylinder liner and be careful not to hit the engine body when disassembling it to prevent damage.
虽然看似简单,但是也需要长期的经验积累才能把一个发动机修好。任何一个小细节的错误都会导致发动机不能正常运转,所以维修发动机这种事情当然需要经验丰富的人员去操作,切不可盲目动手。更多相关内容就来我们网站http://www.jnhgjx.net进行咨询!
Although it may seem simple, it also requires long-term experience to repair an engine. Any minor mistake can cause the engine to malfunction, so repairing the engine requires experienced personnel to operate it, and should not be done blindly.
