解決這一影響生產(chǎn)中的實(shí)際問題就成為必然。汽蝕現(xiàn)象及解決方案2.1汽蝕現(xiàn)象由于葉輪葉片入口附近液體壓力小于或等于液體輸送溫度下的飽和蒸汽壓力時,液體就汽化,同時還可能有溶解在液體內(nèi)的氣體逸出,形成大量氣泡,氣泡隨液體流到葉道內(nèi)壓力較高處時又瞬時凝結(jié)潰滅。在氣泡凝結(jié)潰滅的瞬間,氣泡周圍的液體迅速沖入氣泡凝失形成的空穴,形成強(qiáng)大的局部高頻高壓水擊,金屬表面因疲勞而產(chǎn)生剝蝕。同時,由于活潑氣體(如氧氣)的存在以及氣泡凝結(jié)時產(chǎn)生的局部高溫,導(dǎo)致金屬表面發(fā)生電化學(xué)腐蝕。

為了安全起見,基準(zhǔn)體可選擇足夠大,將危險工作點(diǎn)包括進(jìn)去。在測量泵的噪聲時,用泵聲源確定基準(zhǔn)體。在測量泵機(jī)組的噪聲時,用泵機(jī)組聲源(包括泵和原動機(jī)一起)確定基準(zhǔn)體。球測量表面上的測量在選擇測量表面時,應(yīng)優(yōu)先選擇半球測量面,對單、兩級泵、雙吸泵、中開泵、齒輪泵、滑片泵、螺桿泵等要求選擇半球測量面。1測點(diǎn)位置將傳聲器位于半徑為r,面積為S=2πr2的假想半球表面上。其測點(diǎn)坐標(biāo)如表1左方各欄所示,半球中心為基準(zhǔn)體幾何中心在反射面上的投影,半球的半徑至少為基準(zhǔn)體尺寸的2倍。18745-03 BENTLY NEVADA

在建立壓力管道安裝單位質(zhì)量管理體系時,應(yīng)在以顧客為關(guān)注焦點(diǎn)、確保產(chǎn)品安全和持續(xù)改進(jìn)思想的指導(dǎo)下,首先識別和確定所需要的過程,這包括壓力管道產(chǎn)品形成的直接過程,如:產(chǎn)品要求的評審、施工準(zhǔn)備過程、施工過程、測量和監(jiān)控過程等;也包括壓力管道產(chǎn)品形成的支持過程,如:管理評審、文件控制、不合格品控制、內(nèi)部審核等。壓力管道安裝質(zhì)量管理體系不是一個個過程的簡單集合,而是通過一定的過程網(wǎng)絡(luò)來實(shí)現(xiàn)的。一個過程的輸出通常直接形成為下一個過程的輸入,要搞清楚這些過程的順序和相互作用,特別是過程接口的信息傳遞、分工界限,應(yīng)設(shè)置質(zhì)量綜合管理部門如質(zhì)管辦強(qiáng)化對過程接口的監(jiān)視和協(xié)調(diào),從根本上保證過程接口的受控。
