Description
本發明係有關於一種液體輸送方法及其系統，尤指一種採用同壓、均等流量作為均衡輸送回收的液體輸送方法及其系統為其應用發明者。The invention relates to a liquid conveying method and a system thereof, in particular to a liquid conveying method using the same pressure and equal flow rate as a balanced conveying and recovery system and a system thereof.
按，一般液體的輸送都是透過幫浦(泵)的加壓，而透過管路輸送至目的地，上述的幫浦有以外加引擎方式的設計來驅動，讓幫浦作動而對液體進行連續地吸排的作用，不過由於引擎通常都較為笨重，且又需要使用燃油，對於戶外無電力處的使用可能較為合適以外，若是在室內或對於電力的取得容易處者，則大多是透過馬達或電磁方式來驅動幫浦。Press, the general liquid is delivered through the pump (pump) and through the pipeline to the destination. The above pump is driven by the design of the engine, allowing the pump to act continuously and continuously. The role of the ground suction, but because the engine is usually cumbersome and requires the use of fuel, it may be more suitable for outdoor use without electricity. If it is indoors or easy to obtain electricity, it is mostly through the motor or electromagnetic The way to drive the pump.
然而，現有幫浦僅適於快速輸送及對輸送品質要求較低流體，而無法適用須採慢速輸送之濃稠性流體等，如印刷機；以油墨印刷來說，普遍在印刷機具中利用泵浦作為抽送油墨的配備，此即一般業者所稱的氣動式泵浦，其藉由氣壓驅動泵浦內設之隔膜，而使油墨得以輸送至儲料槽，俾供印刷作業所需，如第六圖所示，利用氣動式泵浦（７）一端連結油墨料筒（７１），另一端管路直接導送至印刷機（８）供墨管（８１），而供墨管（８１）下方適當處設有兩相切之供墨輪（８２），令供墨管（８１）恰位於兩供墨輪（８２）相切處之上方，且兩供墨輪（８２）係呈相反方向轉動並由下往相切處上方轉動，使供墨管（８１）噴出之油墨不致於經兩供墨輪（８２）相切處夾縫流下，而將在兩供墨輪（８２）相切處上方夾設形成之溝槽內竄流並沾染由相切處轉出之兩供墨輪（８２）外緣，同時，多餘之油墨將流向溝槽兩端並流入溝槽兩端所設之集墨槽（８３）內，集墨槽（８３）導接一回流管（８４），並導回油墨料筒（７１）回收油墨；通常採用自然垂流方式，讓集墨槽（８３）的油墨垂流於回流管（８４），再藉由流體靜力學高度差(重力驅動流)或經由毛細效應(常稱為毛細滲透)，使液體由高處往低處流導回油墨料筒（７１），因此，係具有下列缺失：However, the existing pump is only suitable for rapid conveying and requires less fluid for conveying quality, and cannot be applied to thick fluids such as printing machines that require slow conveying, such as printing machines; in ink printing, it is generally used in printing machines. The pump is used as a pumping ink, which is what the average operator calls a pneumatic pump, which drives the pumped diaphragm through the air pressure to allow the ink to be transported to the hopper for printing operations, such as As shown in the sixth figure, one end of the pneumatic pump (7) is used to connect the ink cartridge (71), and the other end of the pipeline is directly guided to the printing machine (8) ink supply tube (81), and the ink supply tube (81) Two tangent ink supply wheels (82) are provided at appropriate places, so that the ink supply tube (81) is located just above the tangent of the two ink supply wheels (82), and the two ink supply wheels (82) are in opposite directions. Rotate and rotate from the bottom to the tangent to make the ink ejected from the ink supply tube (81) not flow through the nip between the two ink supply wheels (82), but will be tangent to the two ink supply wheels (82) Turbulence in the groove formed by the upper clamp and contaminated by the phase At the same time, the excess ink is transferred to the two ends of the ink supply wheel (82), and the excess ink will flow to both ends of the groove and flow into the ink collection groove (83) provided at both ends of the groove, and the ink collection groove (83) is connected. a return pipe (84), and returning ink to the ink cartridge (71) to recover ink; usually adopting a natural vertical flow method, letting the ink of the ink collection tank (83) sag in the return pipe (84), and then by hydrostatics The height difference (gravity driven flow) or via the capillary effect (often referred to as capillary permeation) causes the liquid to flow back from the high to the lower end of the ink cartridge (71), thus having the following deficiencies:
1.回流管須加大管徑(粗管)，管徑越大濃稠液體較容易導流，相對增加成本。1. The return pipe must be increased in diameter (thick pipe). The larger the pipe diameter, the easier the liquid is to conduct, which increases the cost.
2.雖管徑大但一般濃稠液體流動速度慢，容易使油墨揮發乾掉。2. Although the pipe diameter is large, the flow rate of the thick liquid is generally slow, and it is easy to cause the ink to evaporate and dry.
3.輸送過程入液速度快，回流速度慢，使其輸送無法平衡。3. The conveying process is fast and the reflow speed is slow, so that the conveying cannot be balanced.
4.管路清洗不易，且需要藉又大量清水來清潔的回流管，因油墨會乾枯卡於管壁。4. The pipeline cleaning is not easy, and it is necessary to borrow a large amount of clean water to clean the return pipe, because the ink will dry and stick to the pipe wall.
