The power source of the hydraulic breakers
The power source of the hydraulic breakers is the oil flow pressure provided by the pumping station of the excavator, backhoe or loader, which can more effectively clean up the soil in the crevices of floating stones and rocks when excavating the foundation of the building, roads, tunnels profiling or mining. Because the hydraulic breakers are relatively fast reciprocating impact movement, the oil return speed is fast and the relative pulses are large, resulting in the acceleration of hydraulic oil aging and the hydraulic system of the excavator will also be damaged. The excavator should be protected when using the hydraulic breaker to avoid damage to the excavator. In the following points, we will introduce in detail how to use a hydraulic breaker appropriately to ensure that the excavator is not damaged.
Appropriate engine speed. Since the hydraulic hammer breakers have low working pressure and flow requirements, they can work at medium throttle; If the large throttle work will not only not increase the striking force, it will also cause the hydraulic oil to heat abnormally, which will also cause great damage to the hydraulic system, the oblique strike also lead damage of the piston and chisel;
Appropriate engine
Replace the oil seal in time. The oil seal is a wearing part, it is recommended that the hydraulic breaker components work for about 400~1000 hours, and replace the oil seal of the breaker once; When the oil seal leaks, stop working immediately, replace the oil seal, whether the dust on the side is easy to enter the hydraulic system, damage the hydraulic system, damage the hydraulic pump. Operators should regular check maintenance handbook and respect daily maintenance hours;
Keep the pipeline clean, keeping pipeline clean it thoroughly when installing the hydraulic breaker pipeline, and connect it to the inlet and return circuit;
Correct buttering posture, frequency, quantity. If the lubricating grease is replenished in the suspended state of the steel brazing, the grease will enter the blow chamber, and abnormal high-pressure oil will be produced in the strike chamber during the strike, which will enter the hydraulic system and damage the hydraulic pump;
Use a high-quality hydraulic hammer breaker. Low quality hydraulic breakers are prone to problems in design, manufacturing, inspection and other links, and the failure rate is high during usage, which is more leading to cause damage to the excavator.
Hydraulic oil volume and pollution. Since hydraulic oil contamination is one of the main causes of hydraulic pump failure, the contamination status of hydraulic oil should be confirmed in time. Lack of hydraulic oil will cause cavitation phenomenon resulting in hydraulic pump failure, breaker piston cylinder strain, etc.; Recommendation: Check the oil level before daily use. The above is about how to use a hydraulic breaker without damaging the excavator. The hydraulic breaker is used in conjunction with the excavator, and the two complement each other, and both are indispensable under certain operating conditions. I hope the above content is helpful to you, and the correct operation method ensures the efficiency of work. If you have any questions regarding maintenance issues, please feel free to contact us.
