KAYSEN計(jì)量泵如何工作？
根據(jù)品牌和型號(hào)的不同，計(jì)量泵具有多種不同的方法。所有這些方法都需要測(cè)量一定量的化學(xué)品，然后將該產(chǎn)品注入管道或類(lèi)似的容器中。計(jì)量泵設(shè)置有幾個(gè)主要部分：
1. 化學(xué)罐或容器。正在計(jì)量的產(chǎn)品，
2. 腳踏閥。這是一個(gè)連接到吸氣管路上的單向閥。將其放入產(chǎn)品桶中，使泵保持啟動(dòng)狀態(tài)。它應(yīng)該有一個(gè)重量，所以它仍然在產(chǎn)品的鼓桶的底部，有時(shí)它有一個(gè)浮動(dòng)開(kāi)關(guān)連接到它，所以泵有警報(bào)激活，如果產(chǎn)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(xué)腐蝕的塑料（PVC，PE或類(lèi)似的），橡膠或不銹鋼。它有一個(gè)吸入管線連接到入口和計(jì)量管線連接到吸入。泵的機(jī)構(gòu)可能會(huì)有所不同（見(jiàn)下文）。
4. 計(jì)量管線通常是相當(dāng)堅(jiān)硬的PVC或PE管或增強(qiáng)軟管。偶爾在蒸汽，熱水或超高壓應(yīng)用中，生產(chǎn)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(chǎn)品注入產(chǎn)品的那一刻，有一個(gè)注射器點(diǎn)。這是一個(gè)單向閥，因此當(dāng)計(jì)量泵將一定量的產(chǎn)品推入生產(chǎn)線時(shí)，它可以克服輸送管道中的壓力，并使產(chǎn)品流出。一旦產(chǎn)品釋放或泵停止運(yùn)行，單向閥就會(huì)阻止輸送管線中的液體上升到計(jì)量管路并損壞泵。注射器也有一個(gè)噴嘴，使產(chǎn)品被輸送到流體的中間而不是側(cè)壁。隨著時(shí)間的推移，某些產(chǎn)品，尤其是酸和氧化劑，如氯或過(guò)氧化物，會(huì)腐蝕管道的壁，如果在流的邊緣釋放的話(huà)。
6. 控制系統(tǒng)。偶爾會(huì)有一個(gè)控制系統(tǒng)安裝，以確保計(jì)量泵的準(zhǔn)確性，并在特定的時(shí)間打開(kāi)和關(guān)閉。這可以像計(jì)時(shí)器或流量開(kāi)關(guān)一樣簡(jiǎn)單，直到整個(gè)SCADA或類(lèi)似的*控制系統(tǒng)，具有用于pH，氯氣和類(lèi)似的可變速率控制的傳感器來(lái)提高和降低被計(jì)量的水平。它也可能被整合到更復(fù)雜的操作系統(tǒng)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.
