进口机械隔膜计量泵Germany Kaysen

德国KAYSEN凯森进口机械隔膜计量泵概述

机械隔膜计量泵是电机通过直联传动带动蜗轮蜗杆副作变速运动，在曲柄连杆机构的作用下，将旋转运动转变为往复直线运动。

滑杆与膜片直接连接，工作时滑杆往复运动时直接推（拉）动膜片来回鼓动，通过泵头上的单向阀启闭作用完成吸排目的，达到输送液体的功能。2、是可以计量输送液体的机械，也叫定量泵、比例泵。通常描述为：机械隔膜计量泵是一种可以满足各种严格的工艺流程需要，流量可以在0-*范围内无级调节，用来输送液体（特别是腐蚀性液体）一种特殊容积泵。分类一：根据过流部分：一、柱塞、活塞式；二、机械隔膜式；三、液压隔膜式。分类二：根据驱动方式：一、电机驱动；二、电磁驱动；三、气动分类三：根据工作方式一、往复式二、回转式；三、齿轮式其他的分类方式：电控型，气控型，保温型，加热型，高黏度型等。

KAYSEN计量泵如何工作？

根据品牌和型号的不同，计量泵具有多种不同的方法。所有这些方法都需要测量一定量的化学品，然后将该产品注入管道或类似的容器中。计量泵设置有几个主要部分：

1. 化学罐或容器。正在计量的产品，

2. 脚踏阀。这是一个连接到吸气管路上的单向阀。将其放入产品桶中，使泵保持启动状态。它应该有一个重量，所以它仍然在产品的鼓桶的底部，有时它有一个浮动开关连接到它，所以泵有警报激活，如果产品用完了。

3. 泵本身。这可以在尺寸和材料上有所不同，但通常是各种耐化学腐蚀的塑料（PVC，PE或类似的），橡胶或不锈钢。它有一个吸入管线连接到入口和计量管线连接到吸入。泵的机构可能会有所不同（见下文）。

4. 计量管线通常是相当坚硬的PVC或PE管或增强软管。偶尔在蒸汽，热水或超高压应用中，生产线可以是不锈钢。这可以有各种排气，减压，放气阀，但通常只是一条线。

5. 注射器。在产品注入产品的那一刻，有一个注射器点。这是一个单向阀，因此当计量泵将一定量的产品推入生产线时，它可以克服输送管道中的压力，并使产品流出。一旦产品释放或泵停止运行，单向阀就会阻止输送管线中的液体上升到计量管路并损坏泵。注射器也有一个喷嘴，使产品被输送到流体的中间而不是侧壁。随着时间的推移，某些产品，尤其是酸和氧化剂，如氯或过氧化物，会腐蚀管道的壁，如果在流的边缘释放的话。

6. 控制系统。偶尔会有一个控制系统安装，以确保计量泵的准确性，并在特定的时间打开和关闭。这可以像计时器或流量开关一样简单，直到整个SCADA或类似的*控制系统，具有用于pH，氯气和类似的可变速率控制的传感器来提高和降低被计量的水平。它也可能被整合到更复杂的操作系统中。

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.
