摘   要

     柱塞式往复泵的突出优点是:可获得高的排压,且流量与压力无关,适应输送介质十分广泛,吸入性能好,效率高,泵的性能不随压力和输送介质粘度的变动而变动.在当今世界能源紧缺的形势下,往复泵作为节能产品,在石油开发、管道输煤、煤气化工、电站排渣、矿山开采等方面起着重要作用,而且在压力容器检测和实现现代化石油化工工业全面自动化方面也是不可缺少的品种.近年来,其产量明显增长,证实了它在国民经济发展中的地位.
柱塞泵主要用于国内上有关的国民经济部门,该技术在我国的煤炭工业上也发挥其重要作用.
本说明书从以下几个方面介绍了五柱塞泵的设计.
本泵设计时尽可能考虑实现“条例化、通用化、标准化”以利加工、制造、使用和维修.首先搞清楚柱塞泵的分类及其发展历史再说明了柱塞泵的工作原理.
然后选择了电机、减速器等部件,最主要的是五曲轴及连杆液缸体等主要零部件的设计计算,最后是销、阀、箱体等的选择以及泵的保养、维修、安全使用等等.

ABSTRACT

Reciprocating pump the plunger prominent advantages are: the row will be high pressure, and the flow has nothing to do with the pressure to adapt to a wide range transmission medium, inhalation good performance, high efficiency, not with the performance of pump pressure and transmission medium viscosity change in the movement . In today's world energy shortage situation,reciprocating pump as energy-saving products, in the development of oil, coal handling pipes, gas chemical industry, power plants slag discharge, such as mining plays an important role, and pressure vessels in the detection and modernization Petrochemical Comprehensive industrial automation is also indispensable varieties. In recent years, significant growth in its production, confirmed in the position of national economic development.
Piston pump used on the domestic economic sector, the technology in China's coal industry has also played an important role.
The statement from the following areas on a five-piston pump design.
The pump designed to achieve as much as possible to consider "the, universal, standardized" to facilitate the processing, manufacture, use and maintenance. Piston pump first make clear the historical development of the Classification and again that the principle of the piston pump.
Then select the motor, reducer, and other components, most notably the five-cylinder crankshaft and connecting rod, and other major parts of the design basis, the sale is final, valves, tank and pump, and so the choice of the maintenance, repair, security, use And so on.
