现在我国液压油缸企业不断增加液压启闭机的运用也受到关注，以下是一览旗下液压英才网液压李工给大家分享液压启闭的定义一般由液压系统和液压缸组成.在液压系统的控制下,液压缸内的活塞体内壁做轴向往复运动,从而带动连接在活塞上的连杆和闸门做直线运动,以达到开启、关闭孔口的上的，液压系统包括动力装置、控制调节装置、辅助装置等.多套启闭机可共用一个液压系统.
Nowadays, the increasing use of hydraulic opening and closing machines by hydraulic cylinder enterprises in our country has also attracted attention. Below is a list of the definition of hydraulic opening and closing, which is generally composed of a hydraulic system and a hydraulic cylinder Under the control of the hydraulic system, the inner wall of the piston in the hydraulic cylinder undergoes axial reciprocating motion, thereby driving the connecting rod and gate connected to the piston to perform linear motion to open and close the orifice. The hydraulic system includes power devices, control and adjustment devices, auxiliary devices, etc Multiple sets of opening and closing machines can share a hydraulic system
动力装置一般为液压泵,它把机械能转化为液压能.液压泵一般采用容积式泵,如叶片泵和柱塞泵.叶片泵和柱塞泵有结构紧凑,运转平稳,噪音较小,使用寿命长等优点.柱塞泵虽然价格较高,但可以得到高压、大流量,且流量可调.近年来国内液压启闭机普通采用中高压,所以大多数采用柱塞泵.另外,因其重要性,液压启闭机的液压系统一般设置两套液压泵,互为备用.
The power device is generally a hydraulic pump, which converts mechanical energy into hydraulic energy Hydraulic pumps generally use positive displacement pumps, such as vane pumps and plunger pumps Blade pumps and plunger pumps have the advantages of compact structure, smooth operation, low noise, and long service life Although plunger pumps are relatively expensive, they can achieve high pressure, large flow rate, and adjustable flow rate In recent years, domestic hydraulic opening and closing machines have commonly used medium and high pressure, so most of them use plunger pumps In addition, due to its importance, the hydraulic system of a hydraulic hoist is generally equipped with two sets of hydraulic pumps, which are mutually backup
