针对离心泵用于原油集输泵效低、能耗大、维修费用高等问题 ,研制了用于原油集输的 3DY— 4 7/ 6 3三柱塞往复泵。这种泵主要由传动部分、动力端、液力端及底座等组成。传动部分采用一级胶带传动 ,不需要减速器 ,使整机结构简单 ;将吸入端设计为管子与泵头体连接 ,提高了泵的自吸能力 ;巧妙设计了动力端润滑方式 ,使摩擦副润滑可靠 ;选用耐摩性最好的碳纤维密封材料并采用软密封方案 ,解决了泵密封的关键技术难题。往复泵的排量不受压力变化的影响 ,非常符合输油工艺要求 ,现场应用表明 ,这种泵用于远程输油性能优于离心泵 ,工作安全可靠 ,操作、维修方便 ,密封性能好 ,而且可应用于钻井供水等 ,具有较好的推广应用价值
Centrifugal pump for the collection and transportation of crude oil low efficiency, high energy consumption, high maintenance costs, developed for the collection of crude oil 3DY- 4 7/6 3 three plunger reciprocating pump. This pump mainly by the transmission part, power end, hydraulic end and the base and other components. Transmission part of the use of a tape drive, no reducer, so that the whole structure is simple; the suction side of the pipe is designed to connect the pump body, improve pump self-priming capability; clever design of the power end lubrication, the friction pair Lubrication and reliable; selection of the best anti-friction carbon fiber sealing material and the use of soft sealing program to solve the pump key technical problems. Reciprocating pump displacement from the pressure changes, in line with the oil process requirements, on-site application shows that this pump for long-range oil delivery performance superior to centrifugal pump, safe and reliable operation, easy operation and maintenance, good sealing performance, And can be applied to drilling water supply, etc., has a good promotion and application value
