计量泵

计量泵(一)2010-05-14 09:35作为流体精密计量与投加的抱负设备,计量泵如今已被广泛地应用于包括制药、食品饮料和石油化工行业在内的各个领域,在工艺历程担负着强腐蚀性、毒害性、高粘度性和高压力介质的计量新增任务。经过超过半个世纪的实践应用和技术改进,现在计量泵已经进入其高速增持久。现在,成熟的动力驱动方式和液体输送端(泵头)材料技术使得新型计量泵几乎可以完成输送任何常规和特殊介质的要求,其事情压力和容量亦能满足工业出产的绝大多数要求。跟着人们对出产工艺历程指标和自动化程度要求的普遍提高,作为化学药剂计量和新增环节的最终执行机构,计量泵的安全性和可控制性变得日益重要起来。石油化工等行业历来以出产历程的高速自动化而著称,也是集散式、漫衍式和智能式计算机的控制系统应用最广泛的领域之一,故而要求与之相配套的执行器计量泵亦要具备灵活多样的控制模式,可以利便地与计算机系统构成各种控制回路,实现更复杂更精确的历程控制。As the fluid extra measurement and the ideal addition equipment,metering pump has now been widely used in various fields,including pharmaceutical,food&beverage and petroleum chemical industry,responsible for the metering addition of strong corrosive,Toxic,helloghly viscouy viscous and hellogh-pressure media in the process industry.Under more than half-a-century practical application and technical improvements,Now metering pump have entered arapid growing period.Nowadays,mature drive and The materials and technology of pump head make new metering pumps almost complete any transfer of normal and special medium requirements,their working presure and Capacity also can meet the most requirements of industrial production.With general Improvement in requirements of automatic standards and indicators in process,as Last implementing agencies in the link of chemical measurement and addition,the Security and control ofmetering pumps have became increasingly important.Petroleum chemical industry has always been well-known for hellogh automation,as well as one Of themost extensive areas whelloch is distributed,distributed and intelligent computer control system,therefore it need aery-matched actuator,metering pumps also need fleible and diverse controllabie mode,that can easily compose avariety of control loop with computer systems to realize more difficult and more precision control process.
