Because the breaking hammer operates repeatedly and quickly, the oil returns faster and the relative single pulse is relatively large, which causes the acceleration of hydraulic oil aging. Therefore, when the excavator is equipped with a breaking hammer, no matter whether it is the breaking hammer itself or the excavator Pay attention to reasonable and legal application and regular care. This can not only effectively increase the service life of the hydraulic system, but also reduce the frequency of damage in the usual application of the breaker. Now we have sorted out some nursing tips and strengthened the following points to ensure your management Hammer.
1. Correct buttering posture, working frequency and quantity
Insert the drill rod vertically on the ground and press it to the end, otherwise the butter will enter the impact chamber and be brought to the cylinder by the piston to mix with the hydraulic oil, which will cause "black oil" to damage the hydraulic pump, try to add it every 2 hours.
2. Engine speed medium throttle
The breaker has low requirements on the working pressure and flow rate, and can work with a medium throttle. The large throttle will not only increase the penalty, but also cause abnormal temperature rise of the hydraulic oil, which will also cause great damage to the hydraulic system.
3. Replace the hydraulic oil every 600 hours, and replace the core every 100 hours. The lack of hydraulic oil will cause cavitation, which will cause hydraulic pump failure, damage to the piston cylinder of the breaker, etc. It is recommended to check the oil level before using it every day.
4. Oil seal replacement
When the breaker works for more than 600-800 hours, replace the oil seal of the breaker. When the oil seal leaks, stop working temporarily, otherwise the dust can easily enter the hydraulic system, damage the hydraulic system, and damage the hydraulic pump.
5. Keep the pipeline clean
When assembling the breaker pipeline, it should be completely cleaned. Sand and other impurities can easily damage the hydraulic pump after entering the hydraulic system.
6. Warm up
When the breaker is in use, the hydraulic system needs to be preheated to protect the hydraulic system of the excavator;
7. Prohibition of empty play
Empty beating will not only cause the oil temperature to rise, but also form abnormal vibrations that will cause impurities to enter the rigid body of the breaker.
8. Long-term storage
When storing the breaker for a long time, the steel drill must be removed first, and the nitrogen in the upper cylinder should be drained to push the piston to the end, so as to prevent the piston from leaking and rusting or roughening to damage the large pump of the main engine.
