Description

具有電子監視氣閥及活塞之往復泵
本申請案聲明擁有於2005年7月28日提出申請的美國專利申請案60/703,306及於2005年8月1日提出申請的美國專利申請案60/704,290之權益。
習知將氣動往復活塞式泵用於抽吸各種流體。此種泵通常具有機械或氣力操作的氣閥，用以控制活塞兩側的氣流。傳統上並非監視並控制泵本身，而是監視並控制所形成的流體流動，而進行對此種泵的控制。諸如Graco的EXTREME－MIXT M 混合分配器(proportioner)等的先前技術之裝置已可為了控制之目的而監視活塞的位置。
因此，本發明之一目的在於提供一種系統，該系統可對往復氣動馬達(air motor)進行增強式監視及控制，以便可監視活塞位置、週期及流量率、總週期、失控、以及診斷有缺點的氣動馬達及泵下方組件之能力。
該控制器使用被安裝在該氣動馬達的閥座(valve cup)中之一磁鐵以及被安裝在閥蓋中之兩個磁簧感測器(reed sensor)以監視閥的速度及位置。一螺線管被安裝在該閥蓋上，且可使該螺線管將一柱塞延伸到該閥座，以便停止閥的移動，且因而使泵不會失控(通常因沒有流體供應而造成失控)。使用者介面包含一液晶顯示器(LCD)、以及用來設定並控制泵的一些按鈕。可觸發該顯示器，以顯示週期率、流量率(以各種單位表示)、總週期、以及診斷錯誤。設定參數可包括流體單位(夸脫、公升等的單位)以及失控設定點。
設置該等磁簧開關及磁鐵，以便偵測該氣閥何時處於每一衝程之末端位置、或在過渡區中、或以上兩者。控制器計算因該氣閥的變動位置而造成的該等磁簧開關之開啟及閉合的次數，而計算馬達的運轉速率。該控制器然後將該速率與一預定值比較，以便決定該氣動馬達是否處於一失控狀況。如果發生該狀況，則該控制器使螺線管制止換向，因而停止該馬達。此步驟被用來防止溢出的流體及(或)泵的損壞。
一磁阻感測器(magnetoresistive sensor)被設置在該氣動馬達的中心，以便精確地監視活塞位置。來自該感測器的資料加上來自該等氣閥感測器的資料提供了對該泵進行精確控制及診斷所需的輸入，且使本發明適用於量測及複數個組件的應用。
若參照下文中之說明，並配合各附圖，將可更完整地了解本發明的上述這些及其他的目的以及優點，而在全部的該等附圖中，相同的代號係表示相同或類似的零件。
在一氣動往復活塞式泵(10)中，控制器(12)使用被安裝在氣動馬達(18)的閥座(16)中之一磁鐵(14)以及被安裝在閥蓋(22)中之兩個磁簧感測器(20)以監視閥(16)的速度及位置。一螺線管(24)被安裝在閥蓋(22)上，且可使螺線管(24)將一柱塞(26)延伸到閥(16)，以便停止閥的移動，且因而使氣動往復活塞式泵(10)不會失控(通常因沒有流體供應或其他供應導管的軟管有洩漏/破裂而造成失控)。使用者介面(28)包含一液晶顯示器(30)、以及用來設定並控制液晶顯示器(30)的一些按鈕(32)。可觸發液晶顯示器(30)，以顯示週期率、流量率(以各種單位表示)、總週期、以及診斷錯誤。設定參數可包括流體單位(夸脫、公升等的單位)以及失控設定點。
設置該等磁簧開關(20)及磁鐵(14)，以便偵測該氣閥何時處於每一衝程之末端位置、或在過渡區中、或以上兩者。控制器(12)計算因氣閥(16)的變動位置而造成的磁簧開關(20)之開啟及閉合的次數，而計算馬達(18)的運轉速率。控制器(12)然後將該速率與一預定值比較，以便決定氣動馬達(18)是否處於一失控狀況。如果發生該狀況，則控制器(12)使螺線管(24)制止換向，因而停止氣動馬達(18)。此步驟被用來防止溢出的流體及(或)泵的損壞。
將一磁阻感測器(34)設置在氣動馬達(18)的中心，以便精確地監視活塞(36)的位置。來自該感測器(34)的資料加上來自氣閥感測器(20)的資料提供了對該氣動往復活塞式泵(10)進行精確控制及診斷所需的輸入，且使本發明適用於量測及複數個組件的應用。
我們考慮到：可在不脫離最後的申請專利範圍所界定之本發明的精神及範圍下，對該泵的控制作出各種改變及修改。
