1、如果液压机油温过高，要查看压力控制阀的调定值是否偏高，如果过高，降低机器工作压力。
2、待200吨液压机设备自然冷却后，打开放油螺塞，取油样。
3、检查油的粘度指数，粘度过低，就会影响200 ton hydraulic press的压力指标。
4. If the oil is obviously turbid and the hydraulic oil is mixed with water, it is recommended to replace it as soon as possible.
5、在更换液压油的时候，务必把整台液压机液压系统的油全部放掉包括液压箱内的，全部更换新油，同时保证每次更换液压油不得低于100kg。
6, due to the hydraulic machine hydraulic pump and its connection leakage and heat, to tighten the connection, strengthen the seal;
7. When the capacity of the hydraulic oil tank is too small and the heat dissipation condition is poor, the capacity of the oil tank should be increased and the cooling equipment should be installed;
