id="qzr3z39" class="box"><p><p> 怎么判斷壓力表精度等級？ </p> <p> 壓力表精度等級的具體判斷方法如下： </p> <p> <br /> </p> <p> 1.壓力表的精度等級，是以允許誤差占壓力表量程的百分率來表示的，一般分為0.5、1、1.6、2、2.5、3、4七個等級（鍋爐上不用3級和4級），數(shù)值越小，上海不銹鋼溫度表組裝，其精度越高。 </p> <p> <br /> </p> <p> 例如，表盤量程0～2.5 MPa精度2.5級的壓力表，它的指針所示壓力值與被測介質(zhì)的實際壓力值之間的允許誤差，不得超過上2，上海不銹鋼溫度表組裝.5MPa×2.5%=±0.0625 MPa；當壓力表指示壓力為0.8MPa時，實際氣壓在0.7375～0，上海不銹鋼溫度表組裝.8625MPa之間。 </p> <p> <br /> </p> <p> <br /> 上海震揚的WSS413溫度計。上海不銹鋼溫度表組裝</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海不銹鋼溫度表組裝,溫度表" src="https://tyunfile.71360.com/WaterMark/UploadFile/hanmuyibiao/637450218542830965/3472366.png"></div><p> 壓力表量程裝在鍋爐、壓力容器上的壓力表，其比較大量程(表盤上刻度極限值)應(yīng)與設(shè)備的工作壓力相適應(yīng)。壓力表的量程一般為設(shè)備工作壓力的1.5～3倍，比較好取2倍。若選用的壓力表量程過大，由于同樣精度的壓力表，量程越大，允許誤差的***值和肉眼觀察的偏差就越大，則會影響壓力讀數(shù)的準確性;反之，若選用的壓力表量程過小，設(shè)備的工作壓力等于或接近壓力表的刻度極限，則會使壓力表中的彈性元件長期處于比較大的變形狀態(tài)，易產(chǎn)生長久變形，引起壓力表的誤差增大和使用壽命降低。另外，壓力表的量程過小，萬一超壓運行，指針越過比較大量程接近零位，而使操作人員產(chǎn)生錯覺，造成更大的事故。因此，壓力表的使用壓力范圍，應(yīng)不超過刻度極限的60～70%。 </p> <p> 2、測量精度壓力表的精度是以允許誤差占表盤刻度極限值的百分數(shù)來表示的。精度等級一般都標在表盤上，選用壓力表時，應(yīng)根據(jù)設(shè)備的壓力等級和實際工作需要來確定精度。額定蒸汽壓力小于2.45MPa的鍋爐和低壓容器所用的壓力表，其精度不應(yīng)低于2.5級;額定蒸汽壓力大于2.45MPa的鍋爐和中、高壓容器的壓力表，精度不應(yīng)低于1.5級。上海不銹鋼溫度表組裝雙金屬溫度計的安裝方式有徑向的。</p><div

style="text-indent:25px">常規(guī)檢定項目及方法編輯外觀檢查1、耐震壓力表的可見部分應(yīng)無明顯的瑕疵、劃傷，接頭螺紋應(yīng)無明顯的毛刺和損傷。2、表殼內(nèi)灌充液應(yīng)清潔、透明。液面高度位于表殼中心上方0.25D~0.3D(D為儀表外殼直徑)3、壓力表分度盤上應(yīng)有如下標志，制造單位或商標；產(chǎn)品名稱；計量單位和數(shù)字計量器具制造許可證標志和編號，真空表應(yīng)有“-”或“負”字，準確度等級，出廠編號。4、讀數(shù)部分，表玻璃應(yīng)無色透明，不應(yīng)有妨礙讀數(shù)的缺陷。分度盤應(yīng)平整光潔、各標志清晰可辨。5、指針指示端應(yīng)覆蓋**短分度線長度的1/3~2/3，指針指示端的寬度應(yīng)不大于分度線的寬度。6、準確度等級為1，1.6，2.5，4。7、零位，帶有止銷的壓力表，在無壓力或真空時，指針應(yīng)靠近止銷，“縮格”應(yīng)不超過規(guī)定的允許誤差值；無止銷的壓力表，在無壓力或真空時，指針應(yīng)于零位標志內(nèi)，零位標志應(yīng)不超過規(guī)定的允許誤差***值2倍。</p><p> 正確安裝方法，你知道嗎？壓力表國家標準《一般壓力表》GB/T1226-2001中第：直接安裝壓力表、嵌裝（盤裝）壓力表、凸裝（墻裝）壓力表。1、壓力表的安裝位置應(yīng)符合安裝狀態(tài)的要求，表盤一般不應(yīng)水平放置，安裝位置的高低應(yīng)便于工作人員觀測。2、壓力表安裝處與測壓點的距離應(yīng)盡量短，要保證完好的密封性，不能出現(xiàn)泄漏現(xiàn)象。3、在安裝的壓力表前端應(yīng)有緩沖器；為便于檢驗，在儀表下方應(yīng)裝有切斷閥；當介質(zhì)較臟或有脈沖壓力時，可采用過濾器、緩沖器和穩(wěn)壓氣等。四．使用時注意哪些問題？1.儀表適宜在周邊環(huán)境溫度為-40度~+70度。相對濕度不大于80%的場所使用儀表處于正常工作位置。（指垂直安裝）2.一般儀表適用測量對鋼和鋼合金五腐蝕性要求較高的各種流體介質(zhì)的壓力3．不銹鋼儀表適用測量隊耐腐蝕要求較高的各種介質(zhì)的壓力.4.儀表裝接觸和測定點應(yīng)在同一水平上，否則應(yīng)加校正值，（與測量介質(zhì)為氣體的無關(guān)），通常連接導管的長度不得超過50米5.儀表在安裝和拆卸時請用扳手安裝和拆卸，嚴禁用手搬動安裝和拆卸6．為減少對儀表的沖擊，震動和被測介質(zhì)急劇變化的影響，適用時需添加各種緩沖器。7.儀表在測量穩(wěn)定壓力時，不得超過儀表測量上限的3/4，測量波動壓力時。膜盒壓力表壞了怎么辦。</p><div

<p> </p> <p> 玻璃溫度計使用方便，精度可靠。玻璃棒式溫度計按其型狀不同，可以分為直形 (WNG/WNY-01),90°(WNG/WNY-02)和135°(WNG/WNY-03)三種。玻璃棒式溫度計按其用途不同，又可以分為**和有機液體兩種類型。**溫度計可測-30+500 ℃ 以內(nèi)溫度，有機液體為紅色，可測 -100+200 ℃ 以內(nèi)溫度，玻璃棒式溫度計按用戶需要，可以生產(chǎn)各種長度的溫度計，**長可以生產(chǎn)到 3米。 </p> <p> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 上海震揚的衛(wèi)生型壓力表。上海不銹鋼溫度表組裝</p><p

生產(chǎn)廠對退回的這只表進行了20h的靜壓檢查，該表的焊接及彈簧管均為發(fā)生泄漏點。熱電阻為何在生產(chǎn)廠檢查的結(jié)果和現(xiàn)場反映的不銹鋼壓力表情況完全不一致呢？ </p> <p> </p> <p> 之所以出現(xiàn)工廠檢查結(jié)果和現(xiàn)場反映的情況完全不一樣，分析其原因有兩方面。 </p> <p> </p> <p> 一、儀表的使用者沒有準確地反映儀表在現(xiàn)場發(fā)生問題的不銹鋼壓力表實際情況。 </p> <p> </p> <p> 二、生產(chǎn)廠熱電阻銷售人員在儀表發(fā)生問題之后到達現(xiàn)場，壓力表**是聽“現(xiàn)場使用者”單方的意見，而沒有掌握準確詳細的事故資料。上海不銹鋼溫度表組裝</p><p
