The extended arm of excavator can extend the working range of excavator and improve excavation power in engineering construction. However, with the increase of difficulty, more attention should be paid to preventing hydraulic overheating and causing severe incidents when the equipment is transformed into the extended arm of excavator. The next little editor
1. Don't exceed the gauge.
When adding hydraulic oil to the excavator's elongated arm, the injection quantity must be controlled within the oil mark line. Because after overspending, the excavator will generate a lot of heat during the steering process of the damper and transfer it to the hydraulic pump, which will cause the system to heat up, so the oil in the damper should be discharged to the standard oil level.
2. Do a good job of daily inspection
In order to prevent the hydraulic overheating phenomenon of the excavator elongated arm, it is necessary to do a good job of daily inspection of the hydraulic system, check whether there is leakage at each connection, whether the oil quantity in the tank is enough, and whether the working temperature of the pump is normal.
If the filter is blocked or not, it will be useful to check and consult these local areas to prevent the temperature of hydraulic oil from being too high. In addition, check the relief valve of the excavator's elongated arm to ensure that the adjustment pressure, spring and spool seat are normal.
3. Remove and wash snake-shaped pipes regularly
Serpentine tube and multi-tube cooler are the cooling protection devices of hydraulic system, so in order to prevent the hydraulic overheating of excavator elongated arm, it is necessary to use sodium hydroxide and sodium carbonate regularly to clean the oil contamination and then use warm water to clean it. If the serpentine tube and multi-tube cooler can be immersed in a diluted sulfuric acid solution for 40 minutes, then the cleaning effect of the serpentine tube and multi-tube cooler can be achieved. It will be better.
Hydraulic system overheating is a serious danger for excavator elongation arm, so it is necessary to ensure high quality elongation arm equipment.
Not only do we know which manufacturer of the excavator's elongated arm is good, but also do a good job of hydraulic overheating protection in operation, so as to ensure that the excavator's elongated arm in the process of operation is not dangerous. Here are three measures to prevent hydraulic overheating of excavator elongated arm in actual operation. I hope I can help you in life.
