The reason why the reaction arm of hydraulic wrench cannot be lifted with load
source:Industry News release time:2021-03-20 Article author:Rosit Popular:Air band saw
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.
Check the hydraulic wrench before use:
1) Electric hydraulic pumps should not be used in flammable and explosive environments. Pneumatic hydraulic pumps should be used.
2) Check that the working voltage of the electric pump meets 220V.
3) Check the triple device of hydraulic wrench pump pressure adjustment, filtration and oil injection, perform drainage, add 46# anti-wear hydraulic oil, and adjust the intake pressure.
4) Check that the oil level of the oil mark of the hydraulic oil pump is above the 0 line, and the hydraulic oil is clear and transparent. Special hydraulic oil should be added, and other oils are strictly prohibited.
5) Check whether the ultra-high pressure hose is bent or damaged; when connecting, straighten out the hose without tangling, wipe the plug and socket clean and free of dirt, insert the quick-release connector to the end to ensure the connection is reliable, and lock the threaded sleeve by hand , Otherwise the one-way valve in the quick-fitting joint will not open and cannot supply oil normally.
