After the electric forklift starts to operate, it is necessary to conduct regular maintenance and inspections on the electric forklift. In the inspection process, timely repair or replacement of worn parts is a very important and meticulous work. If the parts that should not be repaired are replaced, it will cause waste, then how to judge the degree of wear of the parts?
1. Although the wear degree of general parts has exceeded the tolerance, but it has not exceeded the sub-level matching tolerance, it can continue to be used.
2. The parts cannot complete the intended use function due to wear, such as the clutch loses the function of transmitting power, the hydraulic parts cannot reach the predetermined pressure, and the cam valve system cannot maintain the predetermined movement pattern, it must be replaced or repaired.
3. After some parts are worn out, although they can still perform their functions, their performance is reduced. For example, the transmission gear can still transmit the predetermined torque and speed after wear, but the excessive gap results in increased noise and reduced efficiency, and the smoothness of transmission is damaged. It is necessary to determine whether to repair or replace according to the degree of wear.
It is a very critical matter to determine a wear limit standard for various parts as a basis for judging whether they should be replaced. However, deciding whether to repair or replace parts should not be based solely on the dimensional accuracy, surface roughness, or form and position error of the parts, but also consider the influence of the degree of wear of the parts on the overall performance of the electric forklift.
