3. An important hydraulic component on an excavator is the multi-way distribution valve, which includes a main safety valve, a secondary valve, a relief valve, an oil replenishment valve, etc. If the pressure set by these valves fails to reach the standard pressure, it will result in weak excavation. In addition, if the gap between the valve stem and the valve hole is too large due to wear, the valve stem does not return to its original position completely and the ꯔꯤꯚꯥꯔꯁꯤꯡ ꯑꯁꯤ ꯃꯐꯝ ꯑꯃꯠꯇꯥ ꯂꯩꯇꯦ, ꯏꯟꯇꯔꯅꯦꯜ ꯂꯤꯀꯦꯖꯒꯤ ꯑꯆꯧꯕꯥ ꯃꯁꯤꯡ ꯑꯃꯥ ꯂꯩꯒꯅꯤ, ꯃꯔꯝ ꯑꯗꯨꯅꯥ ꯃꯊꯧ ꯇꯥꯕꯥ ꯐ꯭ꯂꯣ ꯑꯃꯁꯨꯡ ꯇꯞꯅꯥ ꯇꯞꯅꯥ ꯈꯣꯡꯖꯦꯜ. ꯑꯁꯤꯒꯨꯝꯕꯥ ꯁꯃꯁ꯭ꯌꯥꯁꯤꯡꯒꯤꯗꯃꯛꯇꯥ, ꯃꯜꯇꯤ-ꯋꯦ ꯗꯤꯁ꯭ꯠꯔꯤꯕ꯭ꯌꯨꯁꯟ ꯚꯜꯌꯨ ꯑꯁꯤ ꯂꯧꯊꯣꯛꯇꯨꯅꯥ ꯗꯤꯕꯒ ꯇꯧꯅꯕꯒꯤꯗꯃꯛ ꯇꯦꯁ꯭ꯠ ꯕꯦꯟꯆꯇꯥ ꯊꯥꯒꯗꯕꯅꯤ. ꯚꯜꯌꯨ ꯄꯨꯝꯅꯃꯛꯀꯤ ꯄ꯭ꯔꯦꯁꯔ ꯑꯗꯨ ꯁ꯭ꯇꯦꯟꯗꯔꯗ ꯄ꯭ꯔꯦꯁꯔꯗꯥ ꯔꯤꯁꯦꯠ ꯇꯧꯒꯗꯕꯅꯤ, ꯑꯃꯁꯨꯡ ꯚꯜꯌꯨꯝ ꯁ꯭ꯇꯦꯝ ꯑꯃꯁꯨꯡ ꯚꯂꯕ ꯍꯣꯂꯒꯤ ꯃꯔꯛꯇꯥ ꯂꯩꯕꯥ ꯑꯔꯥꯞꯄꯥ ꯑꯗꯨ ꯂꯧꯊꯣꯛꯀꯗꯕꯅꯤ.
