Several easily damaged accessories for the breaker
Since its inception, the hydraulic breaker has been an important tool in the construction industry. The use of the hydraulic hammer is not difficult, just follow the instructions. Here are a few easy-to-damage accessories for the breaker:
1. Steel stop pin. When the stop pin is severely deformed, it is very difficult to replace. Therefore, after every 100 to 150 hours of work, the contact surface between the steel pin and the steel bar should be changed, so that the two contact faces of the steel pin can be used. When the direction of the steel pin is changed, the pin contact The surface should be placed on the side of the steel.
2, Chisel. A pointed steel bar is usually drilled into a soft rock by a sledgehammer to drill a hole in the hole being drilled to blast the rock; it is also commonly used to rock the rock. If the steel is used for a long time, the lower part will be deformed. If the end of the steel is worn, the steel is easy to slip. In this case, the end of the steel is sharpened, and the steel is polished several times to reduce the hardness. If the distance between the steel brazing and the guide sleeve is too large, the piston cannot. Severely hit the steel brazing and cause damage. If the spacing exceeds 9mm, the steel brazing and guiding sleeve should be replaced.
3, The broken hammer easily damaged accessories also include front cover, stop pin, rubber screw plug, hydraulic seals, bracket side bolts, hydraulic hoses and so on. Therefore, each excavator should always be equipped with these accessories in case of emergency. In addition, the actual work needs to be replaced every 600 hours.
Usually pay attention to check whether the bolts are loose or not. The joint pins are excessively worn. Check whether the gap between the drill rod and the bushing is normal. If there is any oil leakage, the low-pressure oil seal is damaged, then you should find a shop to repair and replace the demolition parts.
