低成本、率、以工作质量保证产品质量

After the electric forklift enters the formal working state, it is necessary to regularly carry out maintenance and inspection on the electric forklift. During the inspection process, timely repair or replacement of worn parts is a very important and meticulous task. If parts that should not be repaired are replaced, will it cause waste?

1、一般零件其磨损程度虽已超过公差，但未超过次一级配合公差的，可以继续使用。

1. Although the wear degree of general parts has exceeded the tolerance, but has not exceeded the next level of fit tolerance, they can continue to be used.

2、零件因磨损而不能完成预定使用功能，如离合器丧失传递动力的作用，液压件达不到预定的压力，凸轮配气系统不能保持预定的运动规律，如出现以上情况，就要更换或修复。

2. Parts cannot complete their intended function due to wear and tear, such as the clutch losing its power transmission function, hydraulic components not reaching the predetermined pressure, and the cam valve system not maintaining the predetermined movement pattern. If the above situations occur, replacement or repair are necessary.

3、有些零件在磨损之后，虽然还能完成使用功能，但降低了性能，如传动齿轮发生磨损后仍能传递预定的转矩和速度，但是因间隙过大，噪声增高，效率降低，使传递的平稳性遭到破坏，就要根据磨损程度来决定修复或更换。

3. Some parts, even though they can still perform their intended functions after wear, reduce their performance. For example, if the transmission gear is worn, it can still transmit the predetermined torque and speed. However, due to excessive clearance, increased noise, and reduced efficiency, the smoothness of transmission is damaged. Therefore, repair or replacement should be determined based on the degree of wear.

为各种零件确定一个磨损极限标准作为判断是否应该修换的依据，便是一项十分关键的事情。不过决定零件是否应该修换，不能单以零件的尺寸精度、表面粗糙度或形位误差为依据，还要考虑零件的磨损程度对电动叉车整体性能的影响。

Determining a wear limit standard for various parts as a basis for determining whether they should be repaired or replaced is a crucial matter. However, determining whether a component should be repaired or replaced cannot be solely based on the dimensional accuracy, surface roughness, or form and position error of the component. It is also necessary to consider the impact of component wear on the overall performance of electric forklifts.
