If there are impurities and dirty things in the break hammer pipeline, it will enter the break hammer, and the piston of the break hammer and the oil cylinder and the reversing valve are matched according to the wire level, once the impurities enter the break hammer, it will soon lead to the break hammer piston and the reversing valve pull hair; Process steps to be taken before the hammer installation:
No.1:After the hammer pipe is installed, first close the hammer pipe stop valve on both sides of the forearm! Then let the excavator operator start the excavator, set the accelerator in the middle position, step on the foot switch of the break hammer in the cab with your foot, note: release the foot valve every 1 minute, and then step on the foot valve for another minute, intermittently step on the foot valve for 3 to 5 minutes, turn off the engine!At this time, use a wrench to slowly open the oil inlet stop valve of the lower arm, pay attention to the installer need to stand on the back side of the stop valve when opening, so as not to expose the high-pressure oil to the body, after opening a lot of dirty oil spray out, do not be nervous, this is the dirty things in the pipeline of the breaking hammer mixed with hydraulic oil flow out, after the hydraulic oil flow out to observe whether the hydraulic oil slowly become clear, close the stop valve. Then follow the above steps to open the oil return stop valve on the opposite side, if the hydraulic oil is still not clear, you can hit the excavator again, repeat the steps! Until the pipeline hydraulic oil is clear!
No.2:The pipeline of the break hammer has basically become clear after the oil discharge step, and just finished one step at this time, the second part strengthens the cleaning pipeline effect to ensure that the pipeline is free of impurities! Take out the hammer hose supplied by the hammer manufacturer, use this pipe to connect the inlet and return oil iron pipes at both ends of the forearm in series, and open the stop valves on both sides!At this time, the excavator is on fire, the accelerator is still set in the middle position, step on the break hammer pedal valve with your foot, release once every 1 minute, briefly stop for 5 seconds and then continue to step on, step on the pedal valve intermittent time is also three to five minutes, and then close the stop valve on both sides, then the impurities in the pipeline are completely gone, after oil discharge, This time through the large circulation of impurities through the filter element of the excavator filter, has been basically clean.
No.3:After the above two steps, you can connect the oil pipe of the break hammer to the excavator, before starting to work, you need to check whether the nitrogen pressure of the upper cylinder of the break hammer is standard, the specific pressure should be based on the model of the break hammer you choose, and then hit the butter at the butter nozzle of the lower cylinder body, remember to hit the butter once a day after 2-3 hours of hammering, and the butter gun can hit 15 times each time!
