For modern machinery manufacturing enterprises, the important factor affecting its normal production is whether the mechanical equipment is running well, and whether the hydraulic system of the casting machine is running has become an important indicator of its technical status.
对于现代机械制造企业来说，影响其正常生产的重要因素是机械设备是否运行良好，铸造造型机的液压系统是否运行已成为其技术状况的重要指标。
Therefore, the maintenance of hydraulic control system is particularly important.
所以液压控制系统的维护保养就显得尤为重要。
For the hydraulic system, the use of qualified hydraulic oil is the premise of good operation of the hydraulic system.
对于液压系统来说，使用合格的液压油是液压系统良好运行的前提。
Correct maintenance is the basis for the normal operation of the hydraulic control system, and timely and correct maintenance is the fundamental problem for the normal operation of the hydraulic system.
正确的维护保养是液压控制系统正常运行的基础，按时、正确的维护保养是液压系统正常运行的根本问题。
Hydraulic control system pressure transmission, cooling, lubrication and sealing problems are completed by hydraulic oil, and hydraulic technology system failure and durability caused by many reasons, are caused by the improper selection of the original hydraulic oil.
液压控制系统的压力传递、冷却、润滑和密封问题都是由液压油来完成的，而液压技术系统的故障和耐久性导致的原因有很多，都是由企业对原液压油的选择不当造成的。
Therefore, injection molding machine based on hydraulic control system should be established in our country.
因此，我国应建立基于液压控制系统的注塑机。
When the corresponding hydraulic oil specified in the preparation is used, and other hydraulic oils are used in special cases, the dosage of the two hydraulic oils must be the same.
当使用配制中规定的相应液压油，特殊情况下使用其他液压油时，两种液压油的用量必须相同。
For enterprises of different product varieties, different social grades of hydraulic oil can not be mixed, otherwise, because of the deterioration of hydraulic oil between different chemical components, hydraulic oil, at the same time, the working nature of the use of the forming machine has also changed.
为企业不同产品品种、不同社会等级的液压油不能混合,否则,因为不同的化学成分之间的液压油,液压油的恶化,同时,使用成型机的工作性质也发生了变化。
