有這種情況，從外部看壓力表一切正常，但向儀表加壓時(shí)，即使加壓至測量上限，壓力表指針卻一動不動。若拿起表來不銹鋼壓力表晃一晃，則能聽到表殼內(nèi)有零件的滑動聲。如果將罩殼拆開，發(fā)現(xiàn)是連桿與封口片的連接螺釘脫落，也有的是連桿與扇齒的連接螺釘脫落。 </p> <p> 反生這種情況過后，會使儀表失去了其**基本的使用功能，熱電阻用戶是不會接受的。 </p> <p> 造成連接螺釘脫落的主要原因分析起來應(yīng)是比較簡單的，主要是在儀表調(diào)校完后，沒有將封口片端或扇齒端的螺釘擰緊，這樣在儀表的使用過程中不銹鋼壓力表如反復(fù)加壓，卸壓時(shí)尤其是工作環(huán)境有較大的震動的情況下，熱電阻即會造成連接螺紋的脫落。 </p><p> 即要求儀表的基本誤差應(yīng)小于實(shí)際被測壓力允許的**大***誤差。另外，在選擇時(shí)應(yīng)堅(jiān)持節(jié)約的原則，只要測量精度能滿足生產(chǎn)的要求，就不必追求用過高精度的儀表。彈性壓力表信號遠(yuǎn)傳方式彈性壓力計(jì)一般為直讀式儀表，也可以將彈性元件的變形轉(zhuǎn)換為電信號輸出，下圖給出了幾種彈性壓力計(jì)信號電遠(yuǎn)傳方式原理。圖(a)為電位器式。在彈簧管壓力計(jì)內(nèi)安裝滑線電位器，滑動觸點(diǎn)和電阻的任意一端之間的電壓將取決于滑動觸點(diǎn)位置，即取決于被測壓力。特點(diǎn)：比較簡單，有很好的線性輸出，可靠性較差。圖(b)為霍爾式。其轉(zhuǎn)換原理基于半導(dǎo)體材料的霍爾效應(yīng)。壓力越大，兩面積差越大，則在霍爾元件垂直于磁場和電流方向的另兩側(cè)產(chǎn)生的霍爾電勢也越大。特點(diǎn)：結(jié)構(gòu)簡單，靈敏度高，壽命長，對外部磁場敏感，耐振性差。圖(c)差動變壓器式?？梢苿拥蔫F芯與彈性元件的自由端相連并處于差動變壓器的線圈中，被測壓力越大則鐵芯偏離越多，輸出交流電壓越高，從而可測出壓力值。特點(diǎn)：性好、附加力小、位移范圍較大，處于**位置時(shí)輸出不為零。一般不建議采用彈性壓力表加遠(yuǎn)傳。若需遠(yuǎn)傳顯示，可直接選用精度高、穩(wěn)定性好、可靠性高的壓力變送器。儀表的外殼及導(dǎo)壓系統(tǒng)采用1Cr18Ni9不銹鋼材料。</p><div

特種設(shè)備用壓力表的檢定前文討論了壓力表的檢定范圍和周期，也許會有讀者問，在執(zhí)法監(jiān)察中，常見的是壓力容器、壓力管道和鍋爐上用的壓力表（作為安全附件），它們的檢定周期該怎樣確定？1、簡單壓力容器用壓力表的檢定2007年1月22日，國家質(zhì)監(jiān)總局頒布《簡單壓力容器安全技術(shù)監(jiān)察規(guī)程》（TSGR0003-2007），自2007年7月1日起施行。該規(guī)程第四十三條規(guī)定：使用單位負(fù)責(zé)簡單壓力容器使用的安全管理。符合本規(guī)程范圍的簡單壓力容器，不需要辦理使用登記手續(xù)。在推薦使用壽命內(nèi)的簡單壓力容器，不需要按《壓力容器定期檢驗(yàn)規(guī)則》進(jìn)行定期檢驗(yàn)。同時(shí)，該規(guī)程第四條第（四）項(xiàng)規(guī)定：所用的安全閥、爆破片（帽）、壓力表、水位計(jì)、測溫儀表等安全附件也適用于本規(guī)程。同時(shí)，結(jié)合國家質(zhì)檢總局特種設(shè)備安全監(jiān)察局2007年10月9日發(fā)布的《<簡單壓力容器安全技術(shù)監(jiān)察規(guī)程>常見問題答疑》，簡單壓力容器用壓力表是否需要檢定，需要看簡單壓力容器的投入使用日期。在2007年7月1日后投入使用的簡單壓力容器，壓力表不需檢定。如果簡單壓力容器達(dá)到推薦使用壽命繼續(xù)使用，壓力表需要定期強(qiáng)制檢定。在2007年7月1日前投入使用的簡單壓力容器，壓力表作為安全附件，需定期檢定。上海震揚(yáng)的膜盒用的維卡形狀的，性能好。嘉定區(qū)漢木膜盒壓力表服務(wù)</p><p

每半年至少檢定一次。那么，不是用于安全防護(hù)，如一般工藝管道、容器需要監(jiān)視的壓力表、循環(huán)水管道壓力表、暖氣管道壓力表等，是否需要檢定？檢定的周期又該怎樣確定呢？ </p> <p> 《中華人民***計(jì)量法》第九條第二款規(guī)定，對非強(qiáng)制檢定的計(jì)量標(biāo)準(zhǔn)器具和工作計(jì)量器具，使用單位應(yīng)當(dāng)自行定期檢定或者送其他計(jì)量檢定機(jī)構(gòu)檢定，縣級以上人民**計(jì)量行政部門應(yīng)當(dāng)進(jìn)行監(jiān)督檢查。 </p> <p> 《中華人民***計(jì)量法實(shí)施細(xì)則》于1987年1月19日經(jīng)*** 批準(zhǔn)，1987年 2月

</p> <p> 由此可知，非強(qiáng)制檢定的壓力表也是需要定期檢定，只不過檢定的周期由企業(yè)自行確定。 </p> <p> <br /> 北京漢木膜盒壓力表品牌</p><p
