一种新型计量泵的研制

Development of A New Type of Metering Pump

油田使用的计量泵大都存在泄漏严重、耗电多和易损坏等问题。针对这一情况 ,进行了新型泵的设计研究。采用固定冲程的柱塞泵 ,省去复杂的机械冲程调节装置 ,使柱塞直接推动膜片工作。采用变频方式调节泵的流量 ,泵的结构简单 ,便于维修和养护。试验研究表明 ,该泵运行可靠 ,且能较好地解决目前计量泵存在的问题。

Most of metering pumps adopted in oil fields have some defects such as serious leak, high electric consumption and vulnerability. Aiming at this situation, a new type of metering pump is designed. Adopting piston pump with fixed stroke, the piston directly propels the diaphragm, thus deleting the complex mechanic stroke adjustment equipment. Flow rate is adjusted in variable frequency mode. With a simple structure, this new type of metering pump is convenient for maintenance and repair. Test results show that this pump can operates reliably without the defects mentioned above.
