四柱液压机和四柱油压机好多人听起来认为是一样的，其实真正意思上是有区别的。下面由小编具体跟大家分析一下，四柱油压机和四柱液压机原理上包括实际使用上的区别，相信讲解之后对于液压机和油压机大家就比较清晰的了解了。
1. The four-column hydraulic press, as its name implies, belongs to liquid. The oil pressure generally used can be called hydraulic pressure, and the water pressure can also be called hydraulic pressure, including other liquids, which can be called hydraulic press.
2. The four-column hydraulic press sounds relatively simple. It belongs to oil pressure. The oil tank is filled with hydraulic oil. Usually 46# anti-wear hydraulic oil is used. The hydraulic oil is added to the oil tank of the hydraulic station. The oil pump in the oil tank is driven by the rotation of the motor. The oil pump pumps the hydraulic oil out into the electromagnetic cartridge valve, and the cartridge valve controls the size and direction of the oil intake in the oil tank. In this way.
