一、產(chǎn)品簡(jiǎn)介   Product Brief
    Y系列電接點(diǎn)壓力表廣泛應(yīng)用于石油、化工、化纖、冶金、電站等工業(yè)部門(mén)對(duì)耐蝕、抗振要求較高的工藝流程中測(cè)量各種流體介質(zhì)的壓力。

   Y series All stainless steel pressure gauge Widely used in petroleum, chemical industry, chemical fiber, metallurgy, power plants and other industrial sectors

    Y系列電接點(diǎn)壓力表的整體結(jié)構(gòu)設(shè)計(jì)合理、工藝精致，具有較高的測(cè)量精確度和持久的穩(wěn)定性，因此不僅可提供出口，尤為國(guó)內(nèi)用戶(hù)對(duì)引進(jìn)*進(jìn)技術(shù)裝備中的同類(lèi)儀表實(shí)現(xiàn)國(guó)產(chǎn)化的理想配套產(chǎn)品。
   Y series All stainless steel pressure gauge  The overall structure and reasonable design, fine craft, With high measurement precision and lasting stability, So not only can provide export, Especially the domestic users to the imported instrument of foreign advanced technology and equipment in the To achieve the ideal accessory products localization.

二、結(jié)構(gòu)原理   The structure principle
    Y系列電接點(diǎn)壓力表由導(dǎo)壓系統(tǒng)(包括接頭、彈簧、限流螺釘?shù)?、齒輪傳動(dòng)機(jī)構(gòu)、示數(shù)裝置(指針與度盤(pán))和外殼(包括表殼、表蓋、表玻璃等)所組成。外殼為氣密型結(jié)構(gòu)，能有效地保護(hù)內(nèi)部機(jī)件免受環(huán)境影響和污穢侵入。對(duì)于在外殼內(nèi)充液(一般為硅油或甘油)的儀表，能夠抗工作環(huán)境振動(dòng)較劇烈和減少介質(zhì)壓力的脈動(dòng)影響。
   Yseries All stainless steel pressure gauge By the pressure guide system (including joints, spring, limiting screws), The gear transmission mechanism, showing the number of devices (pointer and dial) and the housing (including watchcase, table covers, table glass) formed. The shell is hermetically sealed structure, Can effectively protect the internal components from environmental influences and dirty invasion. For in the shell filled with liquid (usually a silicone oil or glycerin) instrument, Resistant to environmental vibration is violent And the influence of pressure pulsation reducing medium.

三、技術(shù)指標(biāo)    Technical indicators
