The blackening of the hydraulic oil in the hydraulic breaker is not only because of the dust, but also the wrong posture of filling the butter.
For example: when the distance between the bushing and the steel drill exceeds 8 mm (tip: the little finger can be inserted), it is recommended to replace the bushing. On average, one inner sleeve should be replaced for every two outer sleeves replaced. When replacing hydraulic accessories such as oil pipes, steel pipes, and oil return filters, hydraulic breakers need to clean up the dust or debris at the interface before they can be loosened and replaced.
When filling the butter, be careful not to lay the hydraulic breaker flat, otherwise the butter will be added to the top of the drill rod. When the hydraulic breaker starts to work, the butter will be squeezed to the main oil seal. If this happens, the oil seal of the breaker will be destroyed and the butter will be made butter. Into the cylinder, the system circulation of hydraulic oil brings this grease to the hydraulic system, causing the hydraulic oil to be contaminated.Only half of the standard grease gun is required for each filling.
When replacing hydraulic fittings such as oil pipes, steel pipes, oil return filter elements, etc., you need to clean up the dust or debris at the interface before they can be loosened and replaced.
How to prevent black oil phenomenon?
1. Correctly use the posture of beating butter.
2. Install oil return filter device.
3. Install water spray device to reduce external dust.
4. The upper and lower bushes are too worn, replace the bushes in due course.
5. If the air intake check valve is broken or blocked, check the check valve regularly.
Studies have shown that improper selection, improper use, and untimely maintenance of hydraulic oil will cause 70% of excavator hydraulic system failures, such as affecting the performance of the excavator and the service life of the hydraulic system and components of the excavator. Therefore, we must choose the correct one. Hydraulic oil, normal use, maintenance and replacement of hydraulic oil. When the hydraulic oil continues to use after it turns black, it will cause abnormal hydraulic system pressure and reduce work efficiency. When the hydraulic oil turns black or has a peculiar smell, in order to prevent the protection of the hydraulic system and the life of the components, it is best not to continue using it. When a problem occurs, do not escape. It is necessary to find out the cause of the blackening of the hydraulic oil in time, and it is best to replace it directly . Do a good job of inspection at ordinary times, and deal with problems in time, which not only extends the life of the excavator system and components, but also reduces economic losses.
