The black oil in the hydraulic system of the breaker is not only caused by dust, but also caused by irregular filling of butter. When replacing hydraulic accessories such as oil pipes, steel pipes, and oil return filter elements, you need to clean up the dust or debris at the interface before loosening and replacing. What should I do if I encounter this situation?
1. Replace the dustproof seal in time, and don’t play it frequently.
2. Use the correct posture for buttering.
3. Install oil return filter device and water spray device to reduce outside dust.
4. The upper and lower bushings are too worn, and replace the bushings in due course.
5. The intake check valve is broken or blocked. Check the check valve regularly.
6. Pay attention to whether the size of the steel braze matches the bush.
The power of the breaker comes from the oil seal. Without an oil seal, there is no pressure, and the breaker will not work properly. The oil seal isolates the parts that need to be lubricated from the output parts in the transmission parts, so as not to leak, but also avoids some problems to a certain extent, and is also one of the methods to improve the working efficiency of the breaker.
The hammer is also called hydraulic pick, hydraulic gun, gun machine, crushing head, etc., its power source is the pressure oil provided by the pumping station of the excavator or loader, and the accumulator also enhances the function of the hammer. The following analysis is for everyone a bit.
The accumulator is filled with nitrogen, which uses the breaker to store the remaining energy and the energy of the recoil of the piston during the previous strike. At the same time, the energy is released at the same time to increase the strike ability, usually in the breaker Install the accumulator to increase the strike force of the breaker when the blow energy itself cannot be achieved. Therefore, generally small ones do not have accumulators, and medium and large ones are equipped with accumulators.
In the case of an accumulator, the force will be slightly greater in a single blow. The accumulator is a relatively precise device. There can be no gaps during installation and maintenance, otherwise nitrogen will be leaked, causing the breaker to be weak and the leather cup is damaged. .
Breakers are used in mine mining: mountain opening, mining, screen sieving, and secondary crushing; ladle, slag cleaning, furnace dismantling, and equipment foundation demolition; mountain opening, tunneling, road and bridge demolition, roadbed compaction; highway repair, cement Pavement crushing, foundation excavation and other fields, each part of the hammer is an important part to ensure its normal work.
