Firstly, check if the entire machine is maintained on time and if the hydraulic oil is replaced on time; Is the hydraulic oil circuit blocked? Please check the system pressure at idle and check if the return oil filter element is blocked.
Multiple combinations of rock drills are used to adapt to customers' different drilling needs.
The drilling rig is recommended to idle for a long time, repeat the suggestion, etc., which may cause the fuel mixture to enter the crankcase and cause the oil to become thin.
Low cost: It has the drilling function of a rock drilling rig without affecting the functionality of the excavator itself, and is more flexible due to its superior climbing performance and drilling angle adjustment compared to a rock drilling rig. And the price is only 1/10 of hydraulic rock drilling rigs, even lower than pneumatic rock drilling rigs.
Metal impurities such as iron filings are the main influencing factors. It is possible that the debris is generated by the high-speed rotation of the pump, and all components that rotate with the pump, such as bearings, chambers, etc., are subject to wear. The back and forth movement of the hydraulic valve core and the back and forth movement of the oil cylinder generate debris, but this phenomenon will not occur in the short term.
If your equipment such as excavator to drilling rig, excavator to down the hole drilling rig, excavator to hydraulic drilling rig, etc. is newly purchased, a large amount of metal impurities will be generated during the running in process. When changing the oil, the hydraulic oil in the oil tank should be completely emptied, and the oil tank should be wiped clean with a cotton cloth before adding new oil. If not emptied, there may be a large amount of iron filings remaining in the fuel tank, which can also cause contamination and blackening of the new oil.
Regarding the replacement method of the power belt, the first step is to loosen the belt and place the manual valve on the manual hydraulic pump in the slack position.
The replacement of hydraulic oil should be completed on the same day. For equipment such as excavator to drilling rig, excavator to down the hole drilling rig, excavator to hydraulic drilling rig, etc., the replacement of hydraulic oil should be completed on the same day. Do not continue to replace it overnight because the temperature will decrease at night, and the moisture in the air is prone to form water vapor, condense into water droplets or frost, which can cause metal parts to rust after entering the system.
Firstly, to rule out any circuit issues, the excavator CPU, high and low voltage sensors, solenoid valves, and wiring faults can be checked.
