Description
本發明係關於一種幫浦系統,尤指一種可節省幫浦運轉時所耗能源的幫浦系統。 The invention relates to a pump system, in particular to a pump system which can save energy consumption when the pump is in operation.
一般來說,真空幫浦在運轉時所耗能量與幫浦進氣端與排氣端的氣壓差相關。當幫浦的進氣端(一般連通於製程腔體)與排氣端(一般連通於外界)的壓力差越大,該幫浦運轉時所耗的能量越大。在使用真空幫浦的製程中,由於腔體在製程的初始階段仍處於常壓或一特定氣壓值,該真空幫浦在製程的初始階段最為耗能。當製程穩定後,製程腔體的氣壓已因真空幫浦抽取氣體而降低,因此幫浦的進氣端氣壓較製程的初始階段較低,亦較幫浦的排氣端氣壓低。此時,若該幫浦的排氣端與吸氣端的氣壓差越大,幫浦在製程穩定時的運轉能量消耗則越大。因此,如何降低真空幫浦運轉的能耗為此發明所欲解決的課題。 Generally speaking, the energy consumed by the vacuum pump during operation is related to the air pressure difference between the intake and exhaust ends of the pump. The greater the pressure difference between the intake end of the pump (generally connected to the process chamber) and the exhaust end (generally connected to the outside world), the greater the energy consumed by the pump during operation. In the process of using a vacuum pump, since the cavity is still at normal pressure or a specific air pressure value at the initial stage of the process, the vacuum pump is the most energy consuming at the initial stage of the process. When the process is stable, the air pressure in the process chamber has been reduced by the vacuum pump. Therefore, the air pressure at the inlet end of the pump is lower than the initial stage of the process and lower than the air outlet end of the pump. At this time, if the air pressure difference between the exhaust end and the suction end of the pump is greater, the operating energy consumption of the pump when the process is stable is greater. Therefore, how to reduce the energy consumption of the vacuum pump operation is the subject to be solved by this invention.

其中,各幫浦的進氣閥與排氣閥可為一三向電子控制閥或一三向機械閥,端視實際需求而定。各幫浦設有一運轉電流偵測器,各幫浦的進氣端與排氣端亦設有一氣壓感測器。該進氣端的電子控制閥係由該氣壓感測器所測得之管路氣壓或該運轉電流偵測器所測得之電流值判斷該電子控制閥應將各幫浦腔室連通於該幫浦的進氣端或上游幫浦的排氣端。該排氣端的電子控制閥係由該排氣端下游管路的製程腔體是否有製程來判斷該電子控制閥應將各幫浦腔室連通於下游幫浦的進氣端或外界D,以將製程氣體排出。各幫浦之排氣閥前亦可配置一逆止閥以防止所抽取之氣體回流至各幫浦腔室內。本文所稱「製程」,係指需要使用真空幫浦執行的製程,其中包括可能產生反應氣體的化學反應(如加熱反應、物體燃燒)、物理反應(如相變化),或需使用反應氣體的製程(如薄膜氣相沉積),但實施上不在此限。各幫浦的幫浦轉子係用以將各幫浦的進氣端的氣體吸入,並透過各幫浦的腔室傳至各幫浦的排氣端。此外,各幫浦轉子可經由各幫浦的進氣閥選擇性地將該幫浦的進氣端的氣體抽取至該幫浦的排氣端或將該幫浦上游排氣端的氣體抽取至該幫浦的排氣端。各幫浦進氣閥、排氣閥以及 各閥件與各幫浦其餘部件的連通關係將於下詳述。 Among them, the intake valve and exhaust valve of each pump can be a three-way electronic control valve or a three-way mechanical valve, depending on the actual needs. Each pump is provided with a running current detector, and each pump is also provided with an air pressure sensor at the intake end and the exhaust end. The electronic control valve at the intake end is determined by the pipeline air pressure measured by the air pressure sensor or the current value measured by the running current detector. The electronic control valve should connect each pump chamber to the pump The intake end of the pump or the exhaust end of the upstream pump. The electronic control valve at the exhaust end is judged by the process chamber of the downstream pipeline of the exhaust end to determine whether the electronic control valve should connect each pump chamber to the intake end or the outside D of the downstream pump to Exhaust process gas. A check valve can also be arranged in front of the exhaust valve of each pump to prevent the extracted gas from flowing back into each pump chamber. The term "process" as used herein refers to a process that needs to be performed using a vacuum pump, which includes chemical reactions (such as heating reactions, object burning), physical reactions (such as phase changes) that may generate reactive gases, or those that require the use of reactive gases Process (such as thin film vapor deposition), but the implementation is not limited to this. The pump rotor of each pump is used to suck the gas at the intake end of each pump and pass it through the chamber of each pump to the exhaust end of each pump. In addition, each pump rotor can selectively extract the gas at the intake end of the pump to the exhaust end of the pump or the gas at the exhaust end upstream of the pump to the pump through the intake valve of each pump The exhaust end of the pump. Each pump intake valve, exhaust valve and The communication relationship between each valve and the remaining parts of each pump will be described in detail below.

FIG. 5 is a schematic diagram of the connection relationship between each pump and the cavity when the pump system operates in the third mode according to an embodiment of the present invention.
如第3圖所示,在第二實施例中,該幫浦系統1除了該前端幫浦100與
該末端幫浦200外,另可選擇性地包含一中置幫浦組300,該中置幫浦組300包含至少一中置幫浦300a。其中,該中置幫浦300a包含一中置進氣端301、一中置進氣閥306、一中置排氣端302、一中置排氣閥307、一中置腔體303以及一中置幫浦轉子305。該中置進氣端301連通於一中置製程腔體C,該中置腔體303內形成有一中置腔室304,而該中置幫浦轉子305設置於該中置腔體303的該中置腔室304內。該中置進氣閥306與該中置排氣閥307皆設置於該中置腔體303上,而該中置腔室304分別經由該中置進氣閥306與該中置排氣閥307連通該中置進氣端301與該中置排氣端302。該中置進氣閥306選擇性地將該中置腔室304連通於該中置進氣端301或該前端排氣端102,該中置排氣閥307選擇性地將該中置排氣端302連通於該末端進氣閥206或該外界D。
As shown in FIG. 3, in the second embodiment, the pump system 1 except the front-
如第3圖與第5圖所示,本發明的第二實施例以三個幫浦為例,然而實施上幫浦數量不在此限,可視需求增加中置幫浦300a的數量。其中第5圖所示「連通」代表該欄的連接部位連通於右方欄位的元件或部位,且中置幫浦300a連接至下一列的末端幫浦200。舉例來說,該前端進氣端101連通於該前端進氣閥106,且該前端進氣閥106連通於該前端腔室104。該前端排氣閥107連通於該中置進氣閥306而非連通於該外界D。該中置排氣閥307連通於該末端進氣閥206而非連通於該外界D。該末端排氣閥207則連通於該前端進氣閥106,以使得該幫浦系統1之管路達成一封閉循環。
As shown in FIG. 3 and FIG. 5, the second embodiment of the present invention uses three pumps as an example. However, the number of pumps is not limited to this. The number of
於第二實施例中,若該中置製程腔體B或該末端製程腔體C有製程進行,則該前端幫浦100、該中置幫浦組300與該末端幫浦200處於第一模式操作,為求簡潔,於此不再贅述。當該中置製程腔體B與該末端腔體C皆無製程進行時,該前端排氣閥107、該中置排氣閥307與該末端排氣閥207皆關閉該閥件連通於該
外界D的管路(如第3圖虛線箭頭所示),並分別連通下游的進氣閥,即該前端排氣閥107連通該中置進氣閥306,而該中置排氣閥307連通該末端進氣閥206。此時該中置進氣閥306與該末端進氣閥206分別關閉連通於該中置進氣端301與該末端進氣端201的管路(如第3圖中間與下側虛線箭頭所示)並分別將上游的該前端排氣閥107連通於該中置腔室304與該中置排氣閥307連通於該末端腔室204。此時本發明的該幫浦系統1處於第三模式操作。於此,該中置幫浦轉子305及該末端幫浦轉子205可分別對該前端排氣閥107連通於該中置進氣閥306的管路與該中置排氣閥307連通於該末端進氣閥206的管路進行真空作業。如此一來,該主製程腔體A所產生的氣體透過連通於該主製程腔體A的該前端進氣端101流至該前端進氣閥106與該前端腔室104,再流至該前端排氣端102。由於該前端排氣閥107將該前端排氣端102連通於該中置進氣閥306,使得主製程腔體A所產生的氣體經由該前端排氣端102流至該中置進氣閥306與該中置腔室304,再流至該中置排氣端302。由於該中置排氣閥307將該中置排氣端302連通於該末端進氣閥206,使得主製程腔體A所產生的氣體經由該中置排氣端302與該末端進氣閥206流至該末端腔室204與該末端排氣端202。該第三模式與該第一、第二模式不同之處在於該末端排氣閥207可選擇性地連通該外界D(如第3圖的下側虛線箭頭所示),使得主製程腔體A所產生的氣體經由該外界D排出,或該末端排氣閥207可連通該前端進氣閥106,使得主製程腔體A所產生的氣體再經由前端腔室104循環於幫浦系統1的管路中。第3圖的第三模式即以該末端排氣閥207連通該前端進氣閥106為例。於此模式操作時,該主製程腔體A所產生的氣體由該末端排氣端202排至該前端進氣閥106,且該主製程腔體A所產生的氣體並不會排至該外界D。該前端幫浦100、該中置幫浦組300以及該末端幫浦200分別經由該前端排氣閥107、該中置進氣閥306、該中置排氣閥307、該末端進氣閥206以及該末端排氣閥207相連動,使得該前端幫浦100、該中置幫浦組300與該末端幫浦200同時運轉。
In the second embodiment, if a process is performed in the middle process chamber B or the end process chamber C, the
綜上所述,當本發明的幫浦系統1於第一模式運作時,該前端排氣端102與該末端排氣端202皆連通於該外界D,使得該前端幫浦100與該末端幫浦200皆獨立運轉,且該主製程腔體A與該末端製程腔體C產生的氣體皆排至該外界D。當本發明的幫浦系統1於第二模式運作時,該前端排氣端102連通於該末端進氣閥206,且該前端幫浦100與該末端幫浦200同時運轉,使得該前端幫浦100藉由該前端幫浦轉子105抽取該主製程腔體A產生的氣體至該前端排氣端102,且該末端幫浦200藉由該末端幫浦轉子205抽取該前端排氣端102的氣體,以降低該前端幫浦100的該前端進氣端101與該前端排氣端102的氣壓差,達到降低該前端幫浦100能耗的功效。同理,當本發明的幫浦系統1於第三模式運作時,該前端排氣端102與中置排氣端302分別連通於該中置進氣閥306與該末端進氣閥206,且該前端幫浦100、該中置幫浦組300與該末端幫浦200同時運轉,使得該前端幫浦100藉由該前端幫浦轉子105抽取該主製程腔體A產生的氣體至該前端排氣端102,該中置幫浦組300與該末端幫浦200可分別藉由該中置幫浦轉子305與該末端幫浦轉子205抽取該前端排氣端102與該中置排氣端302的氣體,以降低該前端進氣端101與該前端排氣端102的氣壓差,達到降低該前端幫浦100能耗的功效。藉由此設計,該中置進氣端301與該中置排氣端302的氣壓差亦可降低,以達到降低該中置幫浦300a能耗的功效。此外,該末端排氣端202亦可連通於該前端進氣閥106,使得該前端幫浦100可抽取該末端排氣端202的氣體,以降低該末端進氣端201與該末端排氣端202的氣壓差,達到降低該末端幫浦200能耗的功效。
In summary, when the pump system 1 of the present invention operates in the first mode, the front
