Strengthen these broken hammers with a little bit for 3 years and it will not be broken!

becauseHammerIt is repeated and rapid impact movement, the speed of oil return is faster and the relative pulse is relatively large, which causes the aging of hydraulic oil to accelerate. Therefore, when the excavator is equipped with a breaker, whether it is the breaker itself or the excavator, it is necessary to pay attention to the reasonable and legal Application and frequent maintenance. This can not only effectively extend the service life of the hydraulic transmission system, but also reduce the number of damages in the usual application of the breaker. Now we have sorted out some maintenance tips, strengthen these types, and maintain your breaker well .

Hammer

1. Correct buttering posture, working frequency, total number

Insert the drill rod vertically on the ground and press it to the bottom, otherwise the butter will enter the impact chamber and be brought to the cylinder by the piston rod to mix with the hydraulic oil, which will cause "black oil" to damage the hydraulic pump, try to add it every 2 hours.

2. Accelerator pedal at medium speed of the car

The pressure and flow requirements of the breaker are relatively low, and the accelerator pedal can be operated at a moderate level. The operation of the accelerator pedal will not only increase the penalty, but also cause abnormal temperature rise of the hydraulic oil, which will also cause greater damage to the hydraulic transmission system.

3. Replace the hydraulic oil every 600 hours, and replace the core every 100 hours. The lack of hydraulic oil will also 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 daily use.

4. Skeleton seal replacement

The breaker has been operating for more than 600-800 hours, and the seal of the breaker skeleton should be replaced once. When the oil seal leaks, the operation should be temporarily stopped, otherwise the side dust can easily enter the hydraulic transmission system, damage the hydraulic transmission system, and damage the hydraulic pump.

5. Keep the pipeline clean

When assembling the breaker pipeline, it should be completely cleaned. Sand and other sundries can easily damage the hydraulic pump after entering the hydraulic transmission system.

6. Warm up

When the breaker is in use, the hydraulic transmission system should be preheated to protect the hydraulic system of the excavator;

7. Prohibition of empty play

Air blowing will not only cause the oil temperature to rise, but also form abnormal vibrations that cause impurities to enter the rigid body of the breaker.

8. Long-term storage

When storing the breaker for a long time, be sure to remove the steel drill first, let off the nitrogen in the upper cylinder body and push the piston to the end, so as to prevent the exposed part of the piston rod from rusting or roughening and damaging the main engine oil pump.
