現(xiàn)在我國液壓油缸企業(yè)不斷增加液壓啟閉機的運用也受到關注，以下是一覽旗下液壓英才網(wǎng)液壓李工給大家分享液壓啟閉的定義一般由液壓系統(tǒng)和液壓缸組成.在液壓系統(tǒng)的控制下,液壓缸內的活塞體內壁做軸向往復運動,從而帶動連接在活塞上的連桿和閘門做直線運動,以達到開啟、關閉孔口的上的，液壓系統(tǒng)包括動力裝置、控制調節(jié)裝置、輔助裝置等.多套啟閉機可共用一個液壓系統(tǒng).

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

動力裝置一般為液壓泵,它把機械能轉化為液壓能.液壓泵一般采用容積式泵,如葉片泵和柱塞泵.葉片泵和柱塞泵有結構緊湊,運轉平穩(wěn),噪音較小,使用壽命長等優(yōu)點.柱塞泵雖然價格較高,但可以得到高壓、大流量,且流量可調.近年來國內液壓啟閉機普通采用中高壓,所以大多數(shù)采用柱塞泵.另外,因其重要性,液壓啟閉機的液壓系統(tǒng)一般設置兩套液壓泵,互為備用.

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
