Analysis of the Causes of the Wear of Trolley
The valve is one of the important parts in the trolley process, but it will wear out for a long time.
In the process of trolley, when the balance spring and related valve core and valve seat in the hydraulic valve work under high variable load for a long time, fatigue and cracks will occur, resulting in shortening of the spring length, overall cracking, and sealing of the valve. Damage to the seat when the face falls;
When the residual stress during processing and the external load stress during use exceed the yield strength of the part data, the part will be deformed and the specified function cannot be completed;
Driving in a harsh environment for a long time, causing extensive corrosion. The mixing of hydraulic oil with water or acid is too high. Long-term use will corrode the relevant parts in the hydraulic valve, causing it to lose its due accuracy and become invalid.
