The forgingpumppress divides into the drop forging hydraulic press and the free forging hydraulic press two kinds.
锻造水压机又分为模锻水压机和自由锻水压机两种。

In order to reduce the equipment size, sometimes the large-scale forgingpumppress commonly used high intensity of pressure (about 35 megabars), also uses 100 megabars above ultrahigh voltage.
为减小设备尺寸，大型锻造水压机常用较高压强（35兆帕左右），有时也采用100兆帕以上的超高压。

The influencing factors of the return force of 165MN oil pump direct-drive free forgingpress have been analysed and the design principle of the press's return force given.
