The reason why the reaction arm of hydraulic wrench cannot be lifted with load
The hydraulic wrench and hydraulic pump are severely worn
In low-speed operation, the internal leakage of the pump is serious; in high-speed operation, the pump pressure increases slightly, but due to the wear and internal leakage of the pump, the volumetric efficiency drops significantly, making it difficult to reach the rated pressure. Long-term operation of hydraulic pumps aggravates wear and oil temperature, which causes wear of hydraulic components and aging and damage of seals, loss of sealing ability, deterioration of hydraulic oil, and finally failure.
Unreasonable selection of hydraulic components of hydraulic wrench
The sealing element is also a non-standard part, the manufacturing cost is high and the sealing element is inconvenient to replace. The small cylinder diameter of the boom cylinder will inevitably make the system set pressure high.
Unreasonable design of hydraulic system of hydraulic wrench
Hydraulic pumps often work under full load or long-term overload (high pressure), and the system has hydraulic shocks. If the oil is not changed for a long time, the hydraulic oil is contaminated, which aggravates the wear of the hydraulic pump and causes the pump casing to burst.
Nowadays, the use of hydraulic wrenches is increasing. In order to better use hydraulic wrenches, we also need to have a simple understanding of some basic faults of hydraulic wrenches.
