sb81 hydraulic breaker
There are many reasons for unstable use of hydraulic breaker. Problems with the cylinder, front head ,back head, damage to the overflow valve, insufficient pressure, damage to hydraulic breaker parts, serious wear, etc. are all reasons for the failure. After checking one by one, the cause can be determined and repaired.
What is the situation when the hammer blowing frequency is unstable?
cause:
①The instability may be caused by the problem of the host.
②The hydraulic oil is too small and the flow is insufficient.
③ The overflow valve is damaged.
④The piston, control valve and spare valve are slightly strained.
⑤ The pipeline pressure is not enough.
⑥The pipeline is blocked.
⑦ Instability caused by the reaction force of broken objects.
⑧ The bolts are loose, and the size of the steel drill is wrong.
What can be easily caused by poor oil return?
Possible results:
①The breaking hammer is weak.
②The frequency is too slow.
③The oil temperature is easy to be high.
④ Waste diesel.
It is also easy to cause the frequency of the hydraulic breaker to be unstable. This kind of situation is likely to occur when the oil return filter element is not replaced at the specified time, causing the filter element to be blocked and hindering the smooth flow of the oil return road. The oil return pipe directly returns to the multi-way valve. After long-term operation, the multi-way valve is easy to issue the card and the hydraulic oil heats up quickly, which reduces the striking effect of the breaker.
What are the main reasons for the hydraulic breaker to stuck issue and how to judge?
cause:
- The piston and diverter valve are bruised.
- Spare valve and relief valve issuance
- Insufficient hydraulic oil.
- The oil circuit is not smooth, and it is in a state of semi-blocking and not blocking.
- Insufficient pilot pressure.
- Excessive bushing clearance or a wear.
The unstable use of the hydraulic breaker will affect the use. The above reasons are still easy to see. Jinan Changhao Machinery has more than 15 years experience in manufacturing hydraulic breaker hammer and hydraulic breaker parts. If you encounter any unintelligible breaker failure, please contact us for guidance in time.
The optimum hydraulic oil temperature when the hydraulic breaker is working is 50-60 degrees, and the maximum temperature should not exceed 80 degrees. Otherwise, the load of the hydraulic breaker should be reduced.
