分級(jí)的操作法使底部的晶粒與上部未生長(zhǎng)到產(chǎn)品粒度的互相分，取出管是插在底部，因此產(chǎn)品取出來(lái)的都是均勻的球狀大粒結(jié)晶，這是它大優(yōu)點(diǎn)。但是循環(huán)泵的輸送量在整個(gè)結(jié)晶器內(nèi)是一定的，這就造成結(jié)晶器內(nèi)晶粒的流態(tài)化的終端速度和晶漿濃度(也就是空隙率的大小)的限制，這樣必然帶來(lái)兩個(gè)缺點(diǎn):個(gè)是過(guò)飽和度較大，但是安全的過(guò)飽和介穩(wěn)區(qū)域一般都是很狹窄的，而且生產(chǎn)上往往不允許越過(guò)介穩(wěn)區(qū)的上限，一般都在介穩(wěn)區(qū)中部或偏上一點(diǎn)。

變送器在測(cè)量過(guò)程中，常常會(huì)出現(xiàn)一些故障，故障的及時(shí)判定分析和，對(duì)正在進(jìn)行了生產(chǎn)來(lái)說(shuō)是至關(guān)重要的。我們根據(jù)日常維護(hù)中的經(jīng)驗(yàn)，總結(jié)歸納了一些判定分析方法和分析流程。 法：回顧故障發(fā)生前的打火、冒煙、異味、供電變化、雷擊、潮濕、誤操作、誤維修。直觀法：觀察回路的外部損傷、導(dǎo)壓管的泄漏，回路的過(guò)熱，供電關(guān)狀態(tài)等。檢測(cè)法：a.斷路檢測(cè)：將懷疑有故障的部分與其它部分分來(lái)，查看故障是否消失，如果消失，則確定故障所在，否則可進(jìn)下步查找，如：智能差壓變送器不能正常Hart遠(yuǎn)程通訊，可將電源從表體上斷，用現(xiàn)場(chǎng)另加電源的方法為變送器通電進(jìn)行通訊，以查看是否電纜是否疊加約2kHz的電磁信號(hào)而干擾通訊。 -NPC12K52@力士樂(lè)柱塞泵地址A11VO60DR/10R-NPC12K52力士樂(lè)柱塞泵
