Hydraulic breaker manufacturers share hydraulic breaker malfunction and its solution
Hydraulic breaker is now widely used in highway and railway construction, construction, mining and other industries. However, the working environment of hydraulic breaker is very bad. In the process of using, it may occur faults, seriously affecting the construction of the project. Here we will take you to understand the causes and solutions of the breakdown of hydraulic breaker. I hope it will help you.
1. hydraulic breaker leaks oil, hydraulic breaker leaks oil more places, in the pipe joint, lower cylinder block parts, pneumatic plug or single valve seal ring calculation is bad, cylinder head seal ring calculation is bad.
Solution: replace the sealing ring.
2. Overheating of hydraulic system of hydraulic hydraulic breaker; the reason may be that the pressure setting of safety valve is too low, the cooling capacity is insufficient, the pipe hose is too thin, and the back pressure is too high.
Solution: This kind of problem needs to contact the distributor for testing and solving, and can also be replaced or repaired by themselves.
3. The piston of the hydraulic breaker is not moving, but it may be stuck by the drill rod.
Solution: remove the drill rod and repair with grinding wheel or oil stone.
4. The problem of air leakage is serious; the sealing rings of inflatable screw plug or one-way valve, cylinder jacking and cylinder head may be damaged in these places.
Solution: replace the sealing ring of hydraulic breaker.
5. There are many possible reasons for non-impact of impactor, such as high oil temperature, blockage of pipeline, insufficient hydraulic oil and insufficient oil supply.
Solution: Check the cooling system, reduce the oil temperature, check the oil pump, dredge the pipeline, check the volume efficiency of the oil pump, replace the oil pump if it is low, check the filter and hose if it is insufficient to absorb oil.
6. The abnormal impact of hydraulic breaker mainly has two aspects: one is the surface damage of piston and control valve, the other is that piston is hit empty or not collided with dri
