摘 要:該畢業(yè)設(shè)計是對對偶式雙柱塞高壓清洗泵設(shè)計。高壓清洗泵通過柱塞的水平直線（徑向）位移在液缸工作腔內(nèi)的往復(fù)運動，改變柱塞封閉容腔的大小以進行吸水與排水從而將機械能轉(zhuǎn)變成液壓能。此種泵的流量只取決于工作腔容積變化值及在單位時間內(nèi)的變化次數(shù)（頻率），而在理論上與排出壓力無關(guān)。高壓清洗泵以有壓液體作為動力源，具有效率高、吸入性好、輸送介質(zhì)廣泛等優(yōu)點。
本次設(shè)計是通過對已知數(shù)據(jù)的分析以及參考相關(guān)資料完成的，該高壓清洗泵系雙缸單作用泵，主要由動力端的液壓缸和柱塞往復(fù)泵液力端部分組成。通過對其泵筒、泵閥等零部件及整機進行具體的分析和計算，以及其他非標(biāo)件的經(jīng)驗設(shè)計，完成了本次的設(shè)計任務(wù)。

The Design of Hydraulically-actuated Reciprocating Pump

Abstract: This graduation project is to the hydraulically-actuated reciprocating pump design. The reciprocating pump is draws support the piston/plunger in fluid cylinder work cavity reciprocal motion, causes the work cavity volume to have the periodic variation toachieve the transportation liquid the goal. It is the equipment transforms the mechanical energy as the fluid pressure energy. This kind pumps the current capacity is only decided by the work cavity volume change value and in the unit time change number of times, and in theoretically has nothing to do with the delivery pressure. Hydraulic reciprocating pump is driven by variable pumps and pressure liquid. In oil drilling, oil field injection of chemical agents hydraulically-actuated reciprocating pump play an irreplaceable role. However, the conventional single-acting piston triplex reciprocating pump too bulky, difficult to maintain, and has a high flow inequality. It has less function to be used for current industrial development.
This design through completes to the known data analysis aswell as the reference correlation data, this hydraulically-actuated reciprocating pump is the three-cylinder single-acting pump, mainly partially is composed by the fluid body and the Hydraulic cylinder. Through its pump tube, valve and other parts and complete machine for specific analysis and calculation, has completed this design task.
