Chemical Dosing Pump Guides and Reviews

化学计量泵制品提供了关于不同类型，品质，耐用性和价格的指导和审查。化学定量泵用于将化学品泵泵在所需介质上。给药是指在特定时间间隔内喂养化学品。

在正确的时间间隔喂食时，化学物质可以以更有效的方式反应。当医生向我们规定药物时，我们可能会遇到剂量。使用给料泵用于将测量的化学物质注入物质中。

Chemical dosing pumps usually pump very small quantities of fluid. Dosing is precision work and one of the main tasks in chemical and process engineering and water treatment. The dosing pumps are small in construction and are powered by small electric motor usually.

They can be controlled by the external control system or internally programmed to alter the flow rate and on/off function as per the need. The dosing pump mainly finds its application in agricultural industry, medicine, and manufacturing industries.

化学计量泵工作过程

计量泵的主要功能是采取一定量的化学品，并在所需的培养基中注射它们。给药泵主要由以下组件制成如下。

化学罐- 坦克含有化学品或待给药的流体。
脚阀- 它是一个单向阀，以避免流体的回流。它放置在泵的吸入管线上。
泵- 抽吸管线安装在泵，并将化学物质吸入泵中。
注射器- 来自泵排出的化学物质流过连接的喷射器。注射器用于将测量量的化学物质转移到所需的培养基中。喷射器还用作单向阀，从而停止化学物质返回泵。
控制系统- 控制系统以准确的方式在所需的时间间隔中控制泵中的化学物质的流速。控制系统还包含浮动开关和传感器，以确定是否达到了所需的流量和时间间隔。如果没有，它们会重新校准流量和定时间隔。它是化学计量泵中最复杂的系统。

给药泵选择

必须考虑以下操作参数来选择化学计量泵：

流量 - 泵入所需培养基的化学物质。由于精密流量要求，不应超大给药泵。流速以每单位时间的体积表示。流速被测量为每分钟加仑（GPM）。
Chemical composition – Chemicals must be checked whether they cause damage to pump like corrosion, erosion and if any chemical reaction happens to the walls of the pump.
粘度 - 粘度是流动的抵抗力。需要评估化学品粘度以确定化学品的平滑流动。高度粘性的流体需要特殊的布置来流过泵。
必须维持环境条件，如泵接触水，空气，化学品与环境反应和安全标准。

给药泵应用

Chemical dosing pumps are used in wide range of industries starting from the agriculture, medicine, mining, food processing, manufacturing to the thermal power plants. Now let us look at few applications of the chemical dosing pumps.

Swimming pools- they are used to maintain the pH value of water, chlorine quantity and to maintain the water quality. Chemicals are kept in a separate dosing tank and are injected by the control system.
Textile industry – used in the process of chemical dyeing and chemical treatment of the clothes.
食品行业 - 它们用于添加食物食谱并保持食品安全以以所需速率混合食品组分。它们有助于维持食品组成纹理，然后帮助保持消费者的健康。
水处理 - 用于加热，冷却和凝结水以保持水质。冷却中的杀生物剂和抑制剂的给药。
农业 - 他们用于在农业领域添加化学品以对抗害虫和昆虫。它们也用于剂量肥料和农业中的其他生长抑制物质。
药物 - 它们用于将测量量的化学物质注入体内，以便将患者保持在头晕状态。使用泵给予碱和酸以更好的pH控制。
电站——用于注入chemicals into the boiler and the feed water to make up the water pressure. They are injected in very small quantities.
建筑 - 他们有助于在管工程和部件中注射抑制剂以防止降解或腐蚀。

给药泵制造商

Chemical dosing pumps are manufactured by the following companies such as IFS solutions, Neptune Chemical Pump corp., Tolexo corporation, Water Treatment products Ltd. and ShunMing Co. Ltd. These pumps are little expensive due to their precision requirement. They cost in the price range of 300$-400$ for small pumps to the price of around 1000$.These pumps are usually used in low flow rate applications.
