What harm does empty beating do to excavator breaking hammer?
Causes of impact of empty driving on excavator crushing hammer:
Nonstandard operation. When the excavator breaking hammer is empty, the piston transmits the impact force to the steel drill, and the steel drill transfers the impact force to the steel drill pin. The steel drill pin is easy to break when it bears a strong impact force. When the steel drill pin is impacted, the impact force will be distributed to the steel drill pin cross pin before and after. At this time, the steel drill pin will top the inner hole of the steel drill pin, resulting in the cracking of the jumping block at the edge of the inner hole and finally the fracture of the lower cylinder block.
Frequent empty beating will break the front body, flat pin and bolt, crack the guard plate, boom and steel drill, and leak oil from the hose and hard pipe.
The treatment method of air beating to excavator crushing hammer: crushing operation is carried out after pressing the striking ore, and the striking angle is 85-95 degrees.
When using the excavator breaking hammer, the phenomenon of empty play of the excavator breaking hammer also often occurs, which is very harmful to the accessories of the excavator breaking hammer. So do you know how to avoid empty play?
In fact, empty beating means that the piston does not hit the drill rod when the excavator crushing hammer is working. There are also two types of empty play, complete empty play and incomplete empty play. Completely empty play means that the piston is not in contact with the drill rod at all, so it is useless to play. At this time, the excavator crushing hammer has no energy output and is converted into heat energy.
Incomplete empty play means that the piston has actually hit the drill rod, but because the excavator did not fix the excavator breaking hammer well, the excavator breaking hammer was lifted, the drill rod went back, moved forward with the piston, and returned to the place where the piston began to move until it hit the flat pin. At this time, the drill rod, piston, flat pin, front cylinder block and bolt rod will be seriously damaged due to the impact force. At this time, the drill rod begins to return. If the piston starts a new round of movement on the way back, the drill rod will be impacted by the piston, which will cause greater damage to the next flat pin. Moreover, if the drill rod strikes the piston, it will accelerate the impact frequency of the piston and aggravate greater damage.
When purchasing the excavator breaking hammer, the manual will contain the item of no empty play, but it is unrealistic to completely avoid empty play. Generally, the excavator breaking hammer will have the ability to withstand empty play, that is, the ability to withstand empty play in a short time.
