（1）无污染，流体只接触甭管，不接触泵体，不会产生相互污染；（2）精度高，流量精度可小于±1%而且不会受介质粘度变化的影响；（3）低剪切力，是输送剪切敏感、侵蚀性强流体的理想工具；（4）密封性好，具有良好的自吸能力，可空转，可防止回流；（5）维护简单，无阀门和密封件。近年来，蠕动泵技术迅速发展，已大量应用于实验室和工业生产，如化工、制药和生物、制陶、水处理以及食品饮料行业等。 蠕动泵多配有与计算机的接口，采用计算机控制，可方便蠕动泵的使用。 对蠕动泵的控制可以分为本地面板操作和计算机控制。本地面板操作是指通过蠕动泵面板上的按键设置蠕动泵的各个参数以及运行状态，从而达到对蠕动泵的本地控制的目的。计算机控制是指通过计算机串口与蠕动泵相连，采用专门的控制软件对其进行控制。 蠕动泵控制软件是在Visual studio 2008环境下，采用微软土工的MFC基础类库开发实现的。蠕动泵控制软件具有手动操作和自动控制两种操作模式。手动操作模式是指在软件界面上手动设置泵运行模式（比如单纯的流速模式、定时模式、定量模式、时间间歇模式、体积间歇模式以及体积+预设时间模式等）、方向、流速、时间、循环次数等参数，在这种操作模式下可实现泵的所有控制方式及状态查询。自动控制模式是指根据实际需要，将泵的运行方式存储在配置的文件中，加载此文件后，程序自动发送相应的一系列控制命令，以达到过程控制的目的，配置文件格式采用INI格式。 (1) no pollution, fluid contact don't tube only, do not touch the pump body, won't produce pollution each other; (2) the high precision and accuracy of flow can be less than + / - 1% and would not be affected by medium viscosity change; (3) low shear force, is the ideal shear sensitive, strong corrosive fluid tools; (4) the good sealing, good self-priming ability, may idling, can prevent the reflux; (5) simple maintenance, no valve and seal. In recent years, the peristaltic pump technology rapid development, has a large number of application in the laboratory and industrial production, such as chemical, pharmaceutical and biotechnology, pottery making, water treatment, food and beverage industry and so on. Peristaltic pump equipped with computer interface, using computer control, easy to use of peristaltic pump. Control of the peristaltic pump can be divided into local panel operation and computer control. Local panel operation refers to through the buttons on the peristaltic pump panel set all parameters of the peristaltic pump and running state, so as to achieve the purpose of the local control of the peristaltic pump. Computer control is to point to by computer serial port is connected to a peristaltic pump, using special control software to control it. Peristaltic pump control software is in Visual studio 2008 environment, using Microsoft's geotechnical MFC foundation class library development. Peristaltic pump control software has manual and automatic control of two operating modes. Manual operation mode is to point to manually pump operation mode in the aspect of software (such as a simple velocity model, time model, quantitative models, time interval, the intermittent mode volume and volume + preset time pattern, etc.), direction, velocity, time, cycle times, parameters, such as in this operating mode can realize all pump control mode and state of the query. Automatic control mode refers to according to actual needs, the operating mode of pump is stored in the configuration file, to load the file, the program automatically send a series of corresponding control commands and to achieve the purpose of process control, configuration file format using INI format.
