電泳槽液循環(huán)簡(jiǎn)介中英對(duì)照版 The sections of "Design Considerations" on Paint Circulation are considered definitive in their specific information and reasons for recommendations. However, the following operational comments should prove helpful. 在“設(shè)計(jì)依據(jù)” 一節(jié)中，就槽液循環(huán)有關(guān)具體數(shù)據(jù)及原因方面已提出明確建議。然而，以下的操作說(shuō)明對(duì)操作是有幫助的。 Pump operation, regardless of type, should be monitored by pressure sensors downstream from the pump. Low pressure should sound an alarm which requires positive response. To avoid the problem of pump overheating, pumps should not be dead-headed. 泵的運(yùn)行（與泵的類型無(wú)關(guān)）要靠裝在泵出口的壓力傳感器監(jiān)控，壓力降低時(shí)有聲音報(bào)警，以進(jìn)行必要的調(diào)整。在系統(tǒng)運(yùn)行期間，避免泵的過(guò)熱問(wèn)題，泵不應(yīng)固定不變。 Filters are usually changed when a specific pressure differential reading occurs. This practice can delay the filter change until the filters reach their maximum filtering capacity and reduce unnecessary changes. Many plants have adopted a change schedule determined by experience on a particular line. However, pressure differential should continue to be taken daily as a precaution against a catastrophic event, and pressure gauges should be regularly replaced (again according to a schedule determined by line experience) to assure reasonable accuracy. 當(dāng)壓差達(dá)到一定讀數(shù)時(shí)，一般要更換過(guò)濾介質(zhì)。這樣過(guò)濾介質(zhì)的更換可以延遲到過(guò)濾器達(dá)到其最大的過(guò)濾容量時(shí)再進(jìn)行，以減少不必要的更換。許多廠家已采用了依據(jù)特定涂裝線的經(jīng)驗(yàn)制定的更換時(shí)間表，然而，壓差讀數(shù)要連續(xù)地每天讀取，以預(yù)防大的事故發(fā)生。壓力表要定時(shí)更換（這也是依據(jù)涂裝線經(jīng)驗(yàn)制定的時(shí)間表），以確保讀數(shù)準(zhǔn)確無(wú)誤。 All filter changes should be recorded in a log which includes the date, time, and filter size. 所有過(guò)濾器的更換都要在值班記錄上做記錄，包括日期，時(shí)間，及濾網(wǎng)規(guī)格。 Piping should be color-coded and labeled with direction arrows to indicate material in the pipe and direction of flow. 管路要涂顏色標(biāo)記及帶指示箭頭的標(biāo)牌，以指示管路內(nèi)的材料及流動(dòng)方向。 Critical valves (for drains, D.I. water. etc.) should be locked or valve handles removed to avoid accidental opening. Far too much paint has been wasted because of the accidental opening of valves. This directive is of primary importance! 一些關(guān)鍵的閥門（排放閥，去離子水等）要鎖上或取下閥門手柄，以防意外打開，因閥門意外打開時(shí)，必將浪費(fèi)大量涂料，這一點(diǎn)極其重要。 Additions to the tank should be volume-metered to avoid tank overflow. Meters should be checked and calibrated periodically. Physical inventory measurements should be taken at least weekly and compared with metered usage. This practice will provide a check-and-balance system and will help to verify meter operation. These checks are critical, especially when just-in-time and consignment inventory practices are operative. 向槽中添加物料要有容積計(jì)量，以防止槽液溢出?？刂苾x表要定期進(jìn)行檢查和校正，至少每周進(jìn)行實(shí)際用料計(jì)量并與儀表計(jì)量值做比較。這樣可嚴(yán)格控制加料及庫(kù)存量，并同時(shí)可校驗(yàn)儀表的精度，這些檢查很關(guān)鍵，特別是在要非常準(zhǔn)確地控制庫(kù)存量的情況下。
