型號表示 Model designations 標記示例：YJZ-100ZT 產(chǎn)品電腦編碼為:1002054301 軸向前邊壓力真空表，安裝形式為軸向盤裝式。產(chǎn)品電腦編碼詳見《一般壓力系列儀表選型指南》。 Marking instance：YJZ-100ZT Production computer coding：1002054301 Axial front pressure vacuum meter. mounted form is axial dial mounted product computer coding, please see the“Guide for type selection of common series instrumentsmeters" 型號規(guī)格 Typesspecifications 結構分解圖 Internal structure 說明: 防爆窗可釋放因過載彈性元件破裂而產(chǎn)生的內(nèi)部壓力，增強了人員及設施的安全性。 Specification:explosion-proof window can release inner pressure caused by break of elastic component when over loaded,thus security of personnelestablishment is ensured. 結構原理 儀表由導壓系統(tǒng)（包括接頭、彈簧管等）、齒輪傳動機構、示數(shù)裝置（指針與表盤）和外殼（包括表殼、表罩、表玻璃等）組成。 彈簧管在壓力和真空的作用下，產(chǎn)生彈性變形引起管端位移，其位移通過機械傳動機構進行放大，傳遞給示數(shù)裝置，再由指針在刻有法定計量單位的度盤上指出被測壓力或真空量值。
Configuration principle
The meter is composed of pressure leading system including joint, spring tube, etc, gear wheel driving machine, indicator device pointermeter dialcrust including meter crust, meter cover, meter glass, etc. Under the action of pressurevacuum, spring tube will produce elastic deformation causing displacement at the end. The displacement is enlarged by mechanical driving devicetransferred to indicator,then the pointer of the meter dial, with measure unit on it, indicates the pressure value or vacuum value 度盤表示方法 Show method of the dial zui小分度值表 Min value of pitch line 如需定制特殊表盤,請在訂單中注明。For customized special meter dial,clear notes shall be made on the order. 缺表格 |
