Treatment method of oil black produced by breaking hammer

2022-11-30

When the breaker is used in engineering, it is not only the damage to the structural parts that must be prevented, but also the condition of the hydraulic oil circuit. For the black oil in the breaker, we have summarized the following treatment methods:

1. Replace the dust seal in time, so you don't have to beat it frequently.

2. The oil black of the breaker hydraulic device is not only caused by smoke and dust, but also may be caused by non-compliant filling of butter. The standard use of buttering posture is to lift the breaker when filling butter, The steel braze is pressed into the piston, and only half a gun of a standard grease gun is required for each refill. (And

And if the steel drill is not pressed tightly when the butter is filled, the filled butter will reach the upper limit of the steel drill tank at this time, and the butter will directly jump to the main oil seal of the breaker when the steel drill is working, and the piston will The reciprocating motion brings the butter into the cylinder of the breaker, and then the hydraulic oil in the cylinder of the breaker is mixed into the excavator

In the hydraulic device, the hydraulic oil has deteriorated and turned black)

3. Refit the oil return filter device, refit the water spray device, and reduce external dust. When replacing hydraulic accessories such as oil pipes, steel pipes, oil return filters, etc., it is necessary to clean up the dust or debris at the interface before loosening and replacing them.

4. The upper and lower shaft sleeves are too worn, so replace the shaft sleeves appropriately.

5. The intake one-way valve is broken or blocked, and the one-way valve should be maintained regularly.

6. For the breaker, pay attention to whether the size of the steel drill is matched with the shaft sleeve.
