The reason why the excavator breaker does not absorb oil and the failure that will occur in a short time

Friends today, let’s talk about the reason why the hydraulic pump does not absorb oil during the application of the excavator breaker and the failure that will occur in a short time. Friends who understand this type of product should have a certain understanding, and its key The power source is the night pump, and it can even be said that its pros and cons directly affect the performance of the various components of the breaker. Then, in the face of the two problems mentioned by the editor today, how did they cause them and how to solve them Well, let's take a look together next.

1. Reasons for not absorbing oil:

1. If the viscosity of the oil is too high, the blade is not flexible enough. Another is the viscosity of the oil itself. Try to choose some oil that is suitable for the breaker of the excavator.

2. Abnormal oil absorption caused by blockage of the suction pipe or filter system. In this case, it is necessary to suspend the operation of the breaker, clean the blockage and replace the hydraulic oil.

3. The inner rotor of the excavator hammer does not rotate. Check the worm, worm gear or gear of the oil pump drive system, whether the fastening screw or positioning pin of the inner rotor is loose, and whether the worm gear and the main shaft worm are meshed normally.

2. Failure in a short period of time:

1. The drill rod breaks in a short period of time. One of the key reasons is that the equipment is not used correctly. The breaker of an excavator cannot be used as a pry rod. This operation is the main reason that the drill rod breaks very easily.

2. The drill rod and bushing of the excavator breaker are abnormally worn, and the friction between the drill rod and bushing will cause a lot of heat. The heat can cause premature wear of the drill rod and bushing and damage to the components. Therefore, in order to prevent this kind of problem, I suggest that everyone can fill butter once after using the breaker for 2 hours.

3. The drill rod stop pin ruptures in a short period of time. When the excavator hammer is performing the crushing operation, the strike target is not suspended early after the rupture, and the drill rod hits the drill rod stop pin several times.
