AI Technical Summary

Technical Problem

In the hydraulic system of mining dump trucks, the hydraulic pump at the end of the drive chain cannot be supported, resulting in insufficient fixing strength, which easily causes vibration or failure. In order to avoid problems, large-size pumps or reduce the number of pumps are selected, which affects the system efficiency.

Method used

A multi-hydraulic pump series fixing device is adopted, including a base, shock absorber, front bracket and rear bracket. The hydraulic pumps are connected through the shock absorber to provide support and reduce vibration. Adjusting pads adjust the assembly gap to ensure reliable fixing.

Benefits of technology

This achieves reliable mounting of multiple hydraulic pumps, reduces vibration at the end of the transmission chain, avoids the risk of failure, and improves the stability and efficiency of the system.
