Essential Troubleshooting Tips for Hydraulic Breaker Issues

Hydraulic breakers are widely used in industries such as road and railway construction, building, and mining. However, their harsh working environments often lead to operational issues that can severely impact project timelines. Here, we explore common hydraulic breaker problems and provide effective solutions based on insights from Yantai breaker manufacturers.

Issue 1: Abnormal Impact
This can occur due to damage to the piston or control valve surfaces, or when the piston is either idling or not making contact with the chisel.

Solution:
Disassemble and clean the components to check for damage. Use oil to smooth any burrs, and polish the valve core and impact piston for smooth operation. Ensure the chisel is firmly pressed against the material being broken.

Issue 2: Lack of Impact
Several factors can cause this, including high oil temperature, clogged lines, insufficient hydraulic oil, or inadequate oil supply.

Solution:
Examine the cooling system to reduce oil temperature, check the oil pump, clear any blockages in the lines, and assess the pump's volumetric efficiency. If low, replace the pump, and inspect filters and hoses for suction issues.

Issue 3: Oil Leakage
Common leakage points include pipe joints, lower cylinder areas, gas fill plug seals, or single-direction valve seals.

Solution:
Replace damaged seals to prevent further leakage.
