When the breaker is used in engineering, it is not only the damage of the structural parts that needs to be prevented, but also the state of the hydraulic oil circuit. For the phenomenon of black oil in the breaker, we summarize the following disposal strategies:
1. Regularly replace the dust seal, and it is not necessary to frequently hit it sideways.
2. The black oil in the hydraulic transmission system of the breaker is not only caused by smoke and dust, but also may be caused by the non-compliance of adding butter. The standard posture for using butter is to lift the breaker when adding butter. Brazed into the piston, you only need to add half a gun of a standard grease gun for each addition. (
And if the steel drill is not pressed tightly when adding butter, the butter added at this time will be at the upper limit of the steel drill groove, and the butter may jump to the main oil seal of the breaker when the steel drill is working, due to the repeated movement of the piston Put the butter into the cylinder of the breaker, and then mix the hydraulic oil in the cylinder of the breaker into the excavator
In the hydraulic transmission system, the hydraulic oil has deteriorated and turned black)
3. Install an oil return filter device and a water spray device to reduce external dust. When replacing oil pipes, steel pipes, oil return filter elements and other hydraulic accessories, it is necessary to clean the dust or debris at the interface before loosening them. Open to replace.
4. The upper and lower bushings are too damaged, and the bushings should be replaced appropriately.
5. The intake one-way valve is broken or blocked, check the one-way valve regularly.
6. Pay attention to whether the size of the steel drill is consistent with the bushing.
The above is the solution to the black oil produced by the breaker. To buy a breaker, please contact us, and we will provide you with high-quality products!
