Abstract
Description
本發明係關於一種泵浦，特別是關於一種往復式泵浦。 This invention relates to a pump, and more particularly to a reciprocating pump.
泵浦是一種用以增加輸入其中的流體之壓力，再將該流體輸出的設備。泵浦需要藉由外力的驅動以使流體增壓，而泵浦以驅動方式分類可分為齒輪泵浦、螺桿泵浦、柱塞泵浦、隔膜泵浦等。 A pump is a device that increases the pressure of a fluid that is introduced into it and then outputs the fluid. The pump needs to be driven by an external force to pressurize the fluid, and the pump can be classified into a gear pump, a screw pump, a plunger pump, a diaphragm pump, and the like.
其中隔膜泵浦通常使用氣體施加壓力於隔膜外並擠壓隔膜內之流體以增加流體壓力，因其利用氣體作動而不易產生火花，而可使用在安全性要求較高之場所。單一個隔膜泵浦作動時，由於隔膜壓縮時與隔膜伸張時之間有一時間差，而導致隔膜內之流體不能持續地以穩定的流量輸出。所以更進一步騷展出具有成對隔膜的往復式泵浦，利用成對隔膜增加流體壓力，並交替地將每個隔膜內的流體分別輪出。往復式泵浦之流體排出量較流體輸入量為小但壓力較高，並可連續地輸出高壓力的流體。 Among them, the diaphragm pump usually uses a gas to apply pressure to the outside of the diaphragm and presses the fluid in the diaphragm to increase the fluid pressure. Since it is operated by the gas and is not easy to generate sparks, it can be used in a place with high safety requirements. When a single diaphragm pump is actuated, there is a time lag between when the diaphragm is compressed and when the diaphragm is stretched, so that the fluid in the diaphragm cannot be continuously output at a steady flow rate. Therefore, the reciprocating pump with a pair of diaphragms is further exhibited, the fluid pressure is increased by the pair of diaphragms, and the fluid in each diaphragm is alternately rotated. Reciprocating pumping fluid discharge is smaller than fluid input but high pressure, and can continuously output high pressure fluid.
隨著電腦工業和半導體產業之發展，因在製程中所使用之化學藥劑燃點較低，且安全性要求較高，所以往復式泵浦普遍地應用於其中，提供化學藥劑的增壓輸出以供濕式化學蝕刻製程、供酸系統製程或洗淨系統製程中使用。往復式泵浦需要能夠提供控制精確的流量及流速，這對於上述製程極為重要，否則將影響生產製程的生產率及產能。因此，如何使往復式泵浦輸出之流體的流量及流速穩定，係為一項重要的課題。 With the development of the computer industry and the semiconductor industry, because the chemicals used in the process have lower ignition points and higher safety requirements, reciprocating pumps are commonly used to provide pressurized output of chemicals for supply. Used in wet chemical etching processes, acid system processes or cleaning system processes. Reciprocating pumps need to be able to provide precise flow and flow rates, which is critical to the above process, which would otherwise affect the productivity and productivity of the manufacturing process. Therefore, how to stabilize the flow rate and flow rate of the reciprocating pump output fluid is an important issue.
然而由於習知的往復式泵浦之構造設計，於成對隔膜內的流體交替輸出時，每次交替輸出之間的時間差不能維持固定，而使得泵浦輸出流體之脈動現象呈現不穩定，造成往復式泵浦輸出流體之流量及流速起伏變化而不均勻。 However, due to the conventional reciprocating pump design, when the fluids in the paired diaphragms are alternately output, the time difference between each alternate output cannot be maintained constant, and the pulsation phenomenon of the pump output fluid is unstable, resulting in instability. The flow rate and flow rate of the reciprocating pump output fluid vary unevenly.
緣此，本發明之目的即是提供一種往復式泵浦，以解決習知技術之問題。 Accordingly, it is an object of the present invention to provide a reciprocating pump to solve the problems of the prior art.

同時參閱第5圖及第6圖所示，第5圖係顯示本發明之往復式泵浦於第一作動狀態之示意圖，第6圖係顯示本發明之往復式泵浦於第二作動狀態之示意圖。在本實施例中，伸縮構件11a受罩覆於一外罩5a內，外罩5a具有一輸氣口51a，空氣輸入機構8經由一輸氣管81a連通於輸氣口51a。相似於伸縮構件11a，伸縮構件11b受罩覆於一外罩5b內，罩覆於伸縮構件11b之外罩5b具有一輸氣口51b，一輸氣管81b連通於輸氣口51。輸氣管81a及輸氣管81b共同連接於一電動閥82，空氣輸入機構8持續地輸出空氣A1至電動閥82處，而電動閥82可控制空氣經由輸氣管81a輸入至外罩5a中，或經由輸氣管81b輸入至外罩5b中。外罩5a之內側壁面上鄰近於伸縮構件11a之處設置有一感測驅動件9a，外罩5b之內側壁面上鄰近於伸縮構件11b之處設置有一感測驅動件9b，感測驅動件9a、9b電連接於電動閥82。液體F1經由共同入水構件3進入往復式泵浦100而持續地流至泵入水口01及泵入水口02。 5 and FIG. 6, FIG. 5 is a schematic view showing the reciprocating pump of the present invention in a first operating state, and FIG. 6 is a view showing the reciprocating pump of the present invention in a second operating state. schematic diagram. In the present embodiment, the telescopic member 11a is covered in a casing 5a. The casing 5a has an air outlet 51a, and the air input mechanism 8 communicates with the air inlet 51a via an air duct 81a. Similar to the telescopic member 11a, the telescopic member 11b is covered in a cover 5b, and the cover 5b covers the telescopic member 11b. The cover 5b has an air outlet 51b, and a gas pipe 81b communicates with the air outlet 51. The gas pipe 81a and the gas pipe 81b are connected in common to an electric valve 82. The air input mechanism 8 continuously outputs the air A1 to the electric valve 82, and the electric valve 82 controls the air to be input into the outer casing 5a via the gas pipe 81a, or via the transmission. The air tube 81b is input into the outer cover 5b. A sensing driving member 9a is disposed on the inner wall surface of the outer cover 5a adjacent to the telescopic member 11a. A sensing driving member 9b is disposed on the inner wall surface of the outer cover 5b adjacent to the telescopic member 11b, and the sensing driving members 9a, 9b are electrically connected. Connected to the electric valve 82. The liquid F1 enters the reciprocating pump 100 via the common water inlet member 3 and continuously flows to the pump inlet nozzle 01 and the pump inlet nozzle 02.
如第5圖所示，當空氣輸入機構8輸出之空氣A1輸入於外罩5b內，伸縮構件11b受空氣擠壓而壓縮作動，而伸縮構件11a受連動構件2之連動而伸張作動。於伸縮構件11a伸張作動時，自泵入水口01進入容水空間S3之液體會經由連通孔131a自容水空間S3流入伸縮空間S1中，而擋水構件15a會受液體之雅動力及浮力之影響在容水空間S3中滑動。並當自泵入水口O1進入之液體有足夠之水壓時，液體之雅動力及浮力會將擋水構件15a向泵出水口O3推動而使擋水構件15a以止出水部153a阻擋泵出水口O3，而使泵出水口03封閉，以使液體持續地注入於伸縮空間S1及容水空間S3中。而伸縮構件11b壓縮作動時，伸縮構件11b會擠壓注入於伸縮空間S2及容水空間S4中之液體。當受伸縮構件11b擠壓之液體有足夠的水壓時，擋水構件15b會向泵入水口O2滑動而以止入水部152b阻擋泵入水口O2，而使泵入水口O2封閉，且注入於伸縮空間S2及容水空間S4中之液體會往泵出水口O4處噴出。 As shown in Fig. 5, when the air A1 output from the air input mechanism 8 is input into the outer cover 5b, the telescopic member 11b is compressed by the air to be compressed, and the telescopic member 11a is extended by the interlocking member 2 to be stretched. When the telescopic member 11a is stretched, the liquid entering the water receiving space S3 from the pump inlet 01 flows into the expansion and contraction space S1 through the communication hole 131a, and the water retaining member 15a is subjected to the liquid power and buoyancy. The influence slides in the water-storing space S3. And when the liquid entering from the pump inlet O1 has sufficient water pressure, the liquid power and buoyancy will push the water blocking member 15a to the pump outlet O3 to cause the water blocking member 15a to block the pump outlet with the water stop portion 153a. O3, the pump outlet 03 is closed to continuously inject the liquid into the expansion space S1 and the water receiving space S3. When the telescopic member 11b is compressed, the telescopic member 11b presses the liquid injected into the expansion and contraction space S2 and the water-receiving space S4. When the liquid pressed by the telescopic member 11b has sufficient water pressure, the water retaining member 15b slides toward the pump inlet port O2 to block the pump inlet port O2 with the water stop portion 152b, and the pump inlet port O2 is closed and injected. The liquid in the expansion space S2 and the water receiving space S4 is ejected toward the pump outlet O4.
而伸縮構件11a伸張至接觸於或測驅動件9a時，感測驅動件9a會控制切換電動閥82中之閥門，使罩覆伸縮構件11b之外罩5b中的空氣排出（如第6圖所示），並使空氣輸入機構8產生之空氣A1輸入至罩覆伸縮構件11a之外罩5a中，伸縮構件11a受空氣擠壓而壓縮作動，而連動使伸縮構件11b伸張作動。於伸縮構件11a壓縮作動時，伸縮構件11a會擠壓注入於伸縮空間S1及容水空間S3中之液體，當受伸縮構件11a擠壓之液體有足夠的水壓時，擋水構件15a會向泵入水口O1滑動而以止入水部152a阻擋泵入水口O1，而使泵入水口01封閉，且注入於伸縮空間S1及容水空間S3中之液體會往泵出水口O3處噴出。於伸縮構件11b伸張作動時，自泵入水口O2進入容水空間S4之液體會經由連通孔131b流入伸縮空間S2中，而擋水構件15b會受液體之推動力及浮力之影響在容水空間S4中滑動。並當自泵入水口O2進入之液體有足夠之水壓時，液體之推動力及浮力會將擋水構件15b向泵出水口O4推動而使擋水構件15b以止出水部153b阻擋泵出水口O4，而使泵出水口O4封閉，以使液體持續地注入於伸縮空間S2及容水空間S4中。 When the telescopic member 11a is extended to contact with the measuring or driving member 9a, the sensing driving member 9a controls the switching of the valve in the electric valve 82 to discharge the air in the outer cover 5b of the covering telescopic member 11b (as shown in Fig. 6). The air A1 generated by the air input mechanism 8 is input to the outer cover 5a of the cover telescopic member 11a, and the telescopic member 11a is compressed by the air to be compressed, and the telescopic member 11b is actuated by the interlocking action. When the telescopic member 11a is compressed, the telescopic member 11a presses the liquid injected into the telescopic space S1 and the water-receiving space S3. When the liquid pressed by the elastic member 11a has sufficient water pressure, the water-blocking member 15a is directed. The pump inlet port O1 slides to block the pump inlet port O1 with the stop water portion 152a, and the pump inlet port 01 is closed, and the liquid injected into the expansion space S1 and the water receiving space S3 is discharged to the pump outlet port O3. When the telescopic member 11b is stretched, the liquid entering the water receiving space S4 from the pump inlet port O2 flows into the expansion and contraction space S2 via the communication hole 131b, and the water retaining member 15b is affected by the driving force of the liquid and the buoyancy in the water receiving space. Sliding in S4. And when the liquid entering from the pump inlet O2 has sufficient water pressure, the driving force and buoyancy of the liquid pushes the water blocking member 15b toward the pump outlet O4 to cause the water blocking member 15b to block the pump outlet with the water stopping portion 153b. O4, the pump outlet O4 is closed to continuously inject the liquid into the expansion space S2 and the water receiving space S4.
當伸縮構件11b伸張至接觸於成測驅動件9b時，感測驅動件9b會控制切換電動閥82中之閥門，而使罩覆伸縮構件11a之外罩5a中之空氣排出（返回參閱第5圖所示），並使空氣輸入機構8產生之空氣A1輸入至罩覆伸縮構件11b之外罩5b中，如此形成一種往復式的作動循環。而在沒有提供外罩、輸氣管及空氣輸入機構的狀況下，伸縮構件11a、11b也可藉由外力施力於連接桿23而使伸縮構件11a壓縮作動時伸縮構件11b伸張作動，或使伸縮構件11a伸張作動時伸縮構件11b壓縮作動。 When the telescopic member 11b is extended to contact the test driving member 9b, the sensing driving member 9b controls the switching of the valve in the electric valve 82 to discharge the air in the outer cover 5a of the covering telescopic member 11a (refer to Fig. 5 The air A1 generated by the air input mechanism 8 is input to the outer cover 5b of the cover telescopic member 11b, thus forming a reciprocating operation cycle. In the case where the outer cover, the air pipe, and the air input mechanism are not provided, the telescopic members 11a and 11b can also be biased by the external force to the connecting rod 23, and the telescopic member 11b can be stretched when the telescopic member 11a is compressed, or the telescopic member can be stretched. When the 11a is stretched, the telescopic member 11b is compressed and actuated.
由於上述的往復式泵浦100之構造及作動方式，液體會交替地分別由泵浦本體1a之泵出水口O3或由泵浦本體1b之泵出水。O4輸出，並流至共同出水構件4後再離開往復式泵浦100。 Due to the construction and actuation of the reciprocating pump 100 described above, the liquid is alternately pumped by the pump outlet O3 of the pump body 1a or by the pump body 1b. The O4 is output and flows to the common water discharge member 4 before leaving the reciprocating pump 100.

The air flow rate curve C1 indicates the flow state of the air A1 discharged from the air input mechanism 8, the air amount curve C2 indicates the state of the air amount input into the outer cover 5a, and the air amount curve C3 indicates the state of the air amount input to the outer cover 5b, the switch state The curve C4 indicates the ON/OFF state of the sensing driver 9a, the switch state curve C5 indicates the ON/OFF state of the sensing driver 9b, the volume curve C6 indicates the volume state of the telescopic space S1, and the volume curve C7 indicates the volume of the telescopic space S2. State, height curve C8 indicates the position state of the water retaining member 15a, height curve C9 indicates the position state of the water retaining member 15b, switch state curve C10 indicates the open closed state of the pump inlet nozzle O1, and switch state curve C11 indicates the pump inlet nozzle O2. When the closed state is opened, the switch state curve C12 indicates the opening and closing state of the pump outlet O3, the switch state curve C13 indicates the opening and closing state of the pump outlet O4, and the liquid flow rate curve C14 indicates the flow state in the common water inlet member 3, and the liquid flow rate curve C15 The flow rate state in the common water discharge member 4 is indicated.
在本實施例中，自時間T0開始，空氣流量曲線C1表示空氣輸入機構8所排放的空氣A1以流量R1持續而穩定地輸出，而液體流速曲線C14表示共同入水構件3所接受的液體F1以流速V1持續而穩定地輸入。在本實施例中，於時間T0時伸縮構件11a之壓縮量較大，故伸縮空間S1於時間T0時的容積於容積曲線C6中顯示於較低的位置。而伸縮構件11b於時間T0時之壓縮量近似於零，亦即此時的伸縮空間S2之容積較大，故於容積曲線C7中顯示於較高的位置。擋水構件15a及擋水構件15b因其本身重力之因素而於時間T0時高度較低，故於高度曲線C8及高度曲線C9中顯示出擋水構件15a之高度及擋水構件15b之高度於時間T0時位於較低點H1。 In the present embodiment, starting from time T0, the air flow rate curve C1 indicates that the air A1 discharged from the air input mechanism 8 is continuously and stably outputted at the flow rate R1, and the liquid flow rate curve C14 indicates the liquid F1 received by the common water inlet member 3 The flow rate V1 is continuously and stably input. In the present embodiment, the amount of compression of the telescopic member 11a is large at time T0, so that the volume of the telescopic space S1 at time T0 is displayed at a lower position in the volume curve C6. On the other hand, the amount of compression of the telescopic member 11b at time T0 is approximately zero, that is, the volume of the telescopic space S2 at this time is large, so that it is displayed at a higher position in the volume curve C7. The water retaining member 15a and the water retaining member 15b are lower in height at time T0 due to their own gravity. Therefore, the height of the water retaining member 15a and the height of the water retaining member 15b are shown in the height curve C8 and the height curve C9. At time T0, it is at a lower point H1.
於時間T1時，注入共同入水構件3中之液體F1在其中分流而自泵入水口O1流入泵浦本體1a中及自泵入水口O2流入泵浦本體1b中，而推動擋水構件15a及擋水構件15b，使擋水構件15a之高度及擋水構件15b之高度由較低點H1上升。 At time T1, the liquid F1 injected into the common water inlet member 3 is branched therein and flows into the pump body 1a from the pump inlet port O1 and into the pump body 1b from the pump inlet port O2, and pushes the water blocking member 15a and the block. The water member 15b raises the height of the water blocking member 15a and the height of the water blocking member 15b from the lower point H1.
於時間T1至T2時，由於此時泵浦本體1a之容積小於泵浦本體1a之容積，泵浦本體1a相較於泵浦本體1b先充滿液體，液體壓力使擋水構件15a之高度上升至最高點H2而封閉泵出水口O3。而隨復泵浦本體1b中充滿液體，液體壓力使擋水構件15b之高度上升至最高點H2而封閉泵出水口O4。 At time T1 to T2, since the volume of the pump body 1a is smaller than the volume of the pump body 1a at this time, the pump body 1a is first filled with liquid compared to the pump body 1b, and the liquid pressure raises the height of the water blocking member 15a to The pump outlet O3 is closed at the highest point H2. While the pump body 1b is filled with liquid, the liquid pressure raises the height of the water blocking member 15b to the highest point H2 to close the pump outlet O4.
於時間T2至T4時，空氣輸入機構8所排放的空氣A1輸往電動閥82後之導向為輸入至外罩5b中，使外罩5b中之空氣量如空氣量曲線C3所示逐漸增加。伸縮構件11b受外罩5b中空氣所壓縮而伸縮空間S2之容積減少。泵浦本體1b中之液體隨伸縮構件11b受壓縮而推動擋水構件15b向下，使擋水構件15b之高度於時間T3時下降至最低點H1處而封閉泵入水口O2。而泵出水口O4於時間T2起開啟，且因為液體於時間T2前已預先充滿於伸縮空間S2及容水空間S4中，且伸縮構件11b持續而穩定地受壓縮，而使泵浦本體1b中之液體於時間T2起以高於流速V1之流速V2持續穩定地排向共同出水構件4，並使共同出水構件4中以流速V2持續而穩定輸出液體。泵浦本體1a中之液體持續地向上推動擋水構件15a，使擋水構件15a之高度持續維持於最高點H1處而封閉泵出水口O3。伸縮構件11a受連動伸張而使伸縮空間S1容積增加，使液體持續地注入而充滿於泵浦本體1a中。 At time T2 to T4, the air A1 discharged from the air input mechanism 8 is guided to the electric valve 82 to be input into the outer cover 5b, so that the amount of air in the outer cover 5b is gradually increased as indicated by the air amount curve C3. The expansion and contraction member 11b is compressed by the air in the outer cover 5b, and the volume of the expansion and contraction space S2 is reduced. The liquid in the pump body 1b is compressed with the telescopic member 11b to push the water blocking member 15b downward, so that the height of the water blocking member 15b is lowered to the lowest point H1 at time T3 to close the pump inlet O2. The pump outlet O4 is opened at time T2, and since the liquid is pre-filled in the expansion space S2 and the water-containing space S4 before time T2, and the telescopic member 11b is continuously and stably compressed, the pump body 1b is The liquid is continuously and stably discharged to the common water discharge member 4 at a flow rate V2 higher than the flow rate V1 at time T2, and the output liquid is continuously stabilized at the flow velocity V2 in the common water discharge member 4. The liquid in the pump body 1a continuously pushes the water blocking member 15a upward, so that the height of the water blocking member 15a is continuously maintained at the highest point H1 to close the pump water outlet O3. The telescopic member 11a is stretched in conjunction to increase the volume of the telescopic space S1, so that the liquid is continuously injected and filled in the pump body 1a.
於時間T4時，伸縮構件11a伸張至伸縮空間容積S1為最大而接觸到感測驅動件9a，使感測驅動件9a之ON/OFF狀態為ON而傳送電訊號至電動閥82，而使電動閥82切換閥門開啟方向，使空氣輸入機構8所輸出空氣A1之氣流導向為往外罩5a輸入，而外罩5b中之空氣向外排出。 At time T4, the telescopic member 11a extends to the maximum of the telescopic space volume S1 and contacts the sensing driving member 9a, so that the ON/OFF state of the sensing driving member 9a is ON, and the electrical signal is transmitted to the electric valve 82, thereby making the electric motor The valve 82 switches the valve opening direction so that the air flow of the air A1 output from the air input mechanism 8 is directed to the outer cover 5a, and the air in the outer cover 5b is discharged outward.
於時間T4至T6時，空氣輸入機構8所輸出空氣A1持續輸入至外罩5a中，使外罩5a中之空氣量增加，如空氣量曲線C2所表示。伸縮構件11a受壓縮而使伸縮空間S1之容積隨外罩5a中之空氣量增加而減少。泵浦本體1a中之液體隨伸縮構件11a受壓縮而推動擋水構件15a向下，使擋水構件15a之高度於時間T5時下降至最低點H1處而封閉泵入水口O1。且泵出水口O3於時間T4起開啟，而使泵浦本體1a中之液體於時間T4起排向共同出水構件4，且因泵浦本體1a所排出之液體流速與泵浦本體1b所排出之液體流速同樣為V2，而使共同出水構件4中之液號流速持續維持穩定輸出。在這期間，伸縮構件11b受連動伸張而使伸縮空間S2之容積增加，容水空間S4中之液體流向為流往逐漸加大的伸縮空間S2之中，而非從泵出水口O4排出。泵浦本體1b中之液體推動擋水構件15b向上，使擋水構件15b之高度於時間TS時上升至最高點H2處而封閉泵出水口O4，而液體持續地注入而逐漸充滿於泵浦本體1b中。 At time T4 to T6, the air A1 outputted from the air input mechanism 8 is continuously input into the outer cover 5a, so that the amount of air in the outer cover 5a is increased, as indicated by the air amount curve C2. The telescopic member 11a is compressed such that the volume of the telescopic space S1 decreases as the amount of air in the outer cover 5a increases. The liquid in the pump body 1a is compressed with the telescopic member 11a to push the water blocking member 15a downward, so that the height of the water blocking member 15a is lowered to the lowest point H1 at time T5 to close the pump inlet O1. And the pump outlet O3 is opened at time T4, and the liquid in the pump body 1a is discharged to the common water discharge member 4 at time T4, and the liquid flow rate discharged by the pump body 1a is discharged from the pump body 1b. The liquid flow rate is also V2, and the liquid flow rate in the common water discharge member 4 is continuously maintained at a stable output. During this period, the telescopic member 11b is stretched to expand the volume of the telescopic space S2, and the liquid flow in the water-receiving space S4 flows into the gradually expanding telescopic space S2 instead of being discharged from the pump outlet O4. The liquid in the pump body 1b pushes the water blocking member 15b upward, so that the height of the water blocking member 15b rises to the highest point H2 at time TS to close the pump outlet O4, and the liquid is continuously injected to gradually fill the pump body. 1b.
於時間T6時，伸縮構件11b伸張至伸縮空間S2之容積達到最大並接觸到感測驅動件9b，使感測驅動件9b之ON/OFF狀態為ON而傳送電訊號至電動閥82，而電動閥82切換闕門開啟方向，使空氣輸入機構8所輸出空氣A1之氣流導向為往外罩5b輸入，而外罩5a中之空氣向外排出。 At time T6, the telescopic member 11b extends to the maximum volume of the telescopic space S2 and contacts the sensing driving member 9b, so that the ON/OFF state of the sensing driving member 9b is ON and the electrical signal is transmitted to the electric valve 82, and the electric motor The valve 82 switches the opening direction of the door so that the air flow of the air A1 output from the air input mechanism 8 is directed to the outer cover 5b, and the air in the outer cover 5a is discharged outward.
相較於時間T6至T8時往復式泵浦100之作動狀態與於時間T2至T4時往復式泵浦100之作動狀態，除了泵出水口O3於T2至T3時為受擋水構件15a所封閉，而與泵出水口O3於T6至T7時為開啟狀態不同外，其餘大致相同。如以上所述，往復式泵浦100之作動狀態於時間T3後形成一種循環性的作動•而藉此循環性的作動方式，由泵出水口O3及泵出水口O4之流體輸出的時間差距、流量及流速可保持固定，而使共同出水構件4中液體之流速維持穩定，且共同出水構件4中之液體流速相較共同出水構件3中之液體流速更大。 The operating state of the reciprocating pump 100 compared to the time T6 to T8 and the operating state of the reciprocating pump 100 at times T2 to T4 are closed by the water blocking member 15a except that the pump outlet O3 is at T2 to T3. The same is true except that the pump outlet O3 is different from the open state at T6 to T7. As described above, the actuated state of the reciprocating pump 100 forms a cyclical action after time T3. With this cyclical action, the time difference between the fluid output of the pump outlet O3 and the pump outlet O4, The flow rate and flow rate can be kept constant, and the flow rate of the liquid in the common water discharge member 4 is maintained constant, and the liquid flow rate in the common water discharge member 4 is larger than that in the common water discharge member 3.
