進口電磁隔膜計量泵Germany Kaysen
德國KAYSEN凱森進口電磁隔膜計量泵概述
電磁隔膜計量泵僅5種型號即覆蓋了0.4到54升∕小時流量范圍，zui大壓力可達20 bar。
由于泵的5種型號的安裝尺寸幾乎相同，所以不管客戶選擇哪種型號的泵，都可以在工程設計時，預先規劃泵的固定點
主要特點：
電磁隔膜計量泵是計量泵的一個種類，計量泵是一種可以計量被輸送流體的特殊容積式泵。它一般由控制部分、驅動部分、傳動部分及過流部分組成，電磁隔膜計量泵區別與其他計量泵的主要是驅動部分。
電磁隔膜計量泵是由電磁鐵為驅動，為輸送小流量低壓力液體而設計的一種計量泵，它以結構簡單、易于控制、能耗小、計量準確、調節方便以及價格便宜而在行業內受到歡迎，它的設計原則為“簡單方便”，不過它的缺點就是計量流量小（一般90L/h以下），對管路壓力要求比較低，這也從某些方面限制了它在工業上的應用。
主要優點：
●穩定精度±2%（調節比10%-*）
●在泵運行或停止狀態均可調節流量
●安裝空間小
●堅固耐用，維護成本低
●機械驅動PTFE膜片（多種隔膜材質）
●多種材質及泵類結構可選
主要應用：
●輕工
●農業
●民用
●國防
●石油
●化工
●電力
●冶金
●礦山
●造船

KAYSEN計量泵如何工作？
根據品牌和型號的不同，計量泵具有多種不同的方法。所有這些方法都需要測量一定量的化學品，然后將該產品注入管道或類似的容器中。計量泵設置有幾個主要部分：
1. 化學罐或容器。正在計量的產品，
2. 腳踏閥。這是一個連接到吸氣管路上的單向閥。將其放入產品桶中，使泵保持啟動狀態。它應該有一個重量，所以它仍然在產品的鼓桶的底部，有時它有一個浮動開關連接到它，所以泵有警報激活，如果產品用完了。
3. 泵本身。這可以在尺寸和材料上有所不同，但通常是各種耐化學腐蝕的塑料（PVC，PE或類似的），橡膠或不銹鋼。它有一個吸入管線連接到入口和計量管線連接到吸入。泵的機構可能會有所不同（見下文）。
4. 計量管線通常是相當堅硬的PVC或PE管或增強軟管。偶爾在蒸汽，熱水或超高壓應用中，生產線可以是不銹鋼。這可以有各種排氣，減壓，放氣閥，但通常只是一條線。
5. 注射器。在產品注入產品的那一刻，有一個注射器點。這是一個單向閥，因此當計量泵將一定量的產品推入生產線時，它可以克服輸送管道中的壓力，并使產品流出。一旦產品釋放或泵停止運行，單向閥就會阻止輸送管線中的液體上升到計量管路并損壞泵。注射器也有一個噴嘴，使產品被輸送到流體的中間而不是側壁。隨著時間的推移，某些產品，尤其是酸和氧化劑，如氯或過氧化物，會腐蝕管道的壁，如果在流的邊緣釋放的話。
6. 控制系統。偶爾會有一個控制系統安裝，以確保計量泵的準確性，并在特定的時間打開和關閉。這可以像計時器或流量開關一樣簡單，直到整個SCADA或類似的*控制系統，具有用于pH，氯氣和類似的可變速率控制的傳感器來提高和降低被計量的水平。它也可能被整合到更復雜的操作系統中。
How does Kaysen metering pump work?
Depending on the brand and model, metering pumps have many different ways. All of these methods require the measurement of a certain amount of chemicals, which is then injected into a pipe or similar container. The metering pump setup has several main parts:
Chemical tank or container The product being measured,
2. Foot valve. This is a one-way valve connected to the suction line. Put it in the product bucket and keep the pump on. It should have a weight so it is still at the bottom of the product drum and sometimes it has a float switch connected to it so the pump has an alarm activated if the product runs out.
The pump itself. This can vary in size and material but is usually a variety of chemically resistant plastics (PVC, PE or similar), rubber or stainless steel. It has a suction line connected to the inlet and a metering line connected to the suction. The mechanism of the pump may vary (see below).
4. The metering line is usually quite rigid PVC or PE pipe or reinforced hose. Occasionally in steam, hot water or extra high pressure applications, the line can be stainless steel. This can have a variety of exhaust, decompression, deflation valve, but usually just a line.
Syringe. At the moment the product is injected into the product, there is a syringe point. This is a one-way valve so when the metering pump pushes a certain amount of product into the line it can overcome the pressure in the delivery line and allow the product to flow out. Once the product is released or the pump is out of service, the check valve will prevent liquid in the transfer line from rising to the metering line and damaging the pump. The syringe also has a nozzle that allows the product to be delivered to the center of the fluid rather than the side wall. Over time, certain products, especially acids and oxidizers, such as chlorine or peroxide, can corrode the walls of the pipe if released at the edges of the stream.
6. Control system. Occasionally there is a control system installed to ensure the accuracy of the metering pump and to open and close at a specific time. This can be as simple as a timer or flow switch until the entire SCADA or similar central control system has sensors for pH, chlorine and similar variable rate control to raise and lower the metered level. It may also be integrated into more complex operating systems.
