Excavator Centralized Lubrication System

Introduction of Excavator Lubrication System

A single-line centralized lubrication system is used for the lubrication of a excavator. If there is something wrong, the grease pressure sensor at the end of the single-line distributor that monitors the system in real time will send fault signal and stop alarm.The lube supply for each lube point can be set according to the real need. The fault of one lube point will not cause affects on other lube points because they are connected in parallel, which is a redundancy design.

Working Principle

When the pump starts to work, lube is transmitted to the distributor through the supply line. The grease pressure sensor at the end of the distributor works and gives feedback signals. The pressure in supply line increases till safety relief pressure, making sure quantitative lubrication for each lube point. After that, the pump stops working. The pressure in supply line relieves, so does the single-line distributor assisted by auxiliary unloading valve. This round lubrication ends with lube stored for next-round.

Manual Lubrication VS Automatic Lubrication
Compared to manual lubrication, centralized lubrication system is enclosed, which avoids grease leaking and the abrasion of friction pairs.

Advantages of Centralized Lubrication System
1. Automatic system guarantees timing and automatic lubrication, which saves labor (95%) and ensures operators’ safety.
2. Longer truck life, expand your machines’ lifespan for more than 60%
3. Save grease for more than 70%, environmentally sustainable (Advantages of centralized lubrication system) INTRODUCTION OF THE SYSTEM
