As an important equipment in the mining crushing industry, cone crusher has brought a lot of economic benefits to customers. However, due to the harsh working environment, various problems will occur in the cone crusher. The following is a summary of some common fault phenomena and some solutions for crusher maintenance by the after-sales service staff of Jiaozuo Zhongxin, as a reference for various mining machine mechanics.      1. The oil temperature is too high
     Causes: poor oil quality, or insufficient oil; bearing damage; high ambient temperature, no cooling water or low cooling water pressure; blockage of the cooler.
     Solution: change oil, or add oil; replace bearings; supply cooling water or increase cooling water pressure; clean the cooler.
     2. Oil temperature and oil pressure rise
     Cause: The oil pipe or oil ditch is blocked, and the safety valve fails.
     Solution: s for inspection and repair.
     3. After the oil pump is started, the oil pressure is low or the indicator has no oil flow
     Causes: low oil temperature; blocked oil pipe or abnormal operation of oil pump.
     Solution: heat to increase the oil temperature; repair the pipeline or oil pump.
