【摘要】：4JB径向往复泵多用于10MPa以上的各类液压系统中,具有比传统泵体积小,单人拆卸维修方便,工作压力高,流量调节方便,耐冲击振动能力强,工作可靠等优点。广泛应用于石油、化工、清洗、船舶、矿山等行业。目前已经开发制造出来了一个型号的4JB往复泵,但是只有一个型号远远不能满足市场的需求。为了尽快的开拓市场,实现产品的产业化规模化生产,有必要对4JB往复泵进行系列化设计。4JB泵的系列化设计是根据已有的产品型号,扩大4JB往复泵的使用范围,在相同的结构原理下,设计出流量范围2.5-100m3/h,压力范围10-100Mpa的一系列泵,再把设计参数和性能指标进行归类和化简,设计出产品的规格,形成系列。本文主要工作和结论如下： 1.根据往复泵的压力系列和流量系列的国家标准,和柱塞泵的容积效率机械效率对功率的影响,分析了4JB往复泵：额定压力,额定流量,输入功率等主要参数之间的关系,计算出不同的流量和压力所对应的输入功率。根据普通交流电机的功率系数标准和泵的转速范围要求,进行科学规划,得到了电机的功率系列分别是400、250、110、55KW。 2.运用AMEsim仿真软件研究了主轴的转速对往复泵排量的影响,当转速低于1000r/min的时候转速和流量成正比。当转速高于1000r/min之后往复泵的转速和流量不成正比,实际排量小于理论排量,产生了吸空现象。综合分析得到流量的范围是500-1000r/min。 3.根据功率参数系列,并依据泵的功率与柱塞承受载荷的关系,完成了泵的动力端零件轴承和主轴的主要结构和尺寸的系列化设计,并对其中受力较大的一根主轴进行了力学的计算和Ansys分析。综合考虑主轴的转速范围,主轴的偏心距,轴承承受的载荷和流量的范围,完成柱塞的系列化设计。同时根据吸入排出阀的特点完成了阀的系列化设计。 4.在完成了上述设计的基础上,总结设计出来的参数,得到了五种不同直径的柱塞,四种型号的主轴。对柱塞模块和主轴模块经行组合,得到达到要求的流量压力系列。最后通过对比泵类的命名规律,制作4JB径向往复泵的系列型谱。
[Abstract]:The 4JB radial reciprocating pump is used in various hydraulic systems with more than 10MPa , and has the advantages of small volume of traditional pump , convenient disassembly and maintenance of single person , high working pressure , convenient flow regulation , high impact resistance , reliable operation and the like , and is widely applied to industries such as petroleum , chemical industry , cleaning , ships , mines and the like . A 4JB reciprocating pump has been developed and manufactured , but only one model can ' t meet the demand of the market . In order to open up the market as soon as possible and realize the large - scale production of the products , it is necessary to design a series of 4JB reciprocating pumps . Under the same structure principle , a series of pumps with a flow range of 2.5 -100m3 / h and a pressure range of 10 - 100Mpa are designed . The design parameters and performance indexes are classified and simplified , and the specifications and the forming series of products are designed . The main work and conclusion of this paper are as follows : 1 . According to the national standard of the pressure series and flow series of the reciprocating pump and the influence of the mechanical efficiency of the displacement efficiency of the plunger pump on the power , the relationship between the main parameters of the rated pressure , the rated flow rate and the input power is analyzed , and the input power corresponding to different flow and pressure is calculated . According to the standard of the power coefficient of the common AC motor and the rotating speed range of the pump , scientific planning is carried out , and the power range of the motor is 400 , 250 , 110 and 55KW , respectively . 2 . The influence of the rotating speed of the main shaft on the displacement of the reciprocating pump is studied by using the simulation software . When the rotating speed is lower than 1000r / min , the rotation speed and the flow rate are proportional . When the rotating speed is higher than 1000r / min , the speed and flow rate of the reciprocating pump are not directly proportional , the actual displacement is less than the theoretical displacement , and the suction air phenomenon is generated . The comprehensive analysis results in the flow range of 500 - 1000r / min . 3 . According to the series of power parameters and according to the relationship between the power of the pump and the bearing load of the plunger , the series design of the main structure and size of the power end part bearing and the main shaft of the pump is completed , and the mechanical calculation and Ansys analysis are carried out on one main shaft in which the force is larger . The series design of the plunger is completed by taking into account the range of the rotating speed of the main shaft , the eccentricity of the main shaft , the load and the flow rate of the bearing , and the serialization design of the valve is completed according to the characteristics of the suction discharge valve . 4 . On the basis of the above design , the design parameters are summarized , five plungers with different diameters and four types of spindles are obtained . The plunger module and the main shaft module are combined to obtain the required flow pressure series . Finally , the series pattern of the 4JB radial reciprocating pump is produced by comparing the naming rule of the pump class .
