在对某型单活塞手动泵海水淡化装置分析的基础上,设计了1种双活塞手动泵海水淡化装置,并进行机械建模设计和动力学仿真分析。该双活塞手动泵海水淡化装置装利用2个泵活塞的互补式往复运动,产水量大,可达约23 L/h;流量波动较小,产水效率高。可为进行原理样机试制提供依据,同时也为进一步研究设计高性能海水淡化装置提供思路。 Based on the analysis of a single-piston manual pump seawater desalination unit, a double-piston manual pump seawater desalination unit is designed, and the mechanical modeling design and dynamic simulation analysis are carried out. The double-piston hand pump desalination device uses two reciprocating piston reciprocating pump piston, water production capacity, up to about 23 L / h; flow fluctuations smaller, high water production efficiency. It can provide the basis for the prototype test of the prototype, and provide ideas for further research and design of high performance desalination plant.
