Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] 1. Overall structure

[0031] Such as figure 1As shown, the parallel-connected advection plunger pump includes: a drive transmission module 1 , a cylinder plunger module 2 , and a bracket 3 for the whole machine. The cylinder plunger module 2 includes a main cylinder module 21 and an auxiliary cylinder module 22; the overall assembly and motion relationship is:

[0032] The whole machine support 3 is all the structural parts (the installation base of the drive transmission module 1 and the cylinder plunger module 2), all the structural parts are fixed on the whole machine support 3 by fastening screws, and positioning pin holes are set on the bottom plate 305 to ensure the transmission The coaxiality between the mechanism A and the master cylinder module 21 and the coaxiality between the transmission mechanism B and the auxiliary cylinder module 22 . The cyli...

Abstract

The invention relates to a parallel type advection plunger pump, which comprises a drive transmission module (1), a cylinder body plunger module (2) and a complete machine support (3). The parallel type advection plunger pump provided by the invention can be used for accurately and quantitatively conveying a required liquid, and a liquid flow is not influenced by backward-stage pressure fluctuation, so that the liquid is ensured to be output continuously and stably. The device provided by the invention is mainly used in a water purification system in an environmental control and life support subsystem in a space station, provides current-rated water to be treated to a purifier, can ensure the output accuracy to be unaffected when the pressure in the purifier is changed, and has the characteristics of accuracy in supplying, capability of being unaffected by backward-stage pressure, high output efficiency and output continuousness. The device provided by the invention adopts a novel series seal structure, so that the product processing difficulty is reduced, the product accuracy is ensured, the requirements on sealing reliability and long service life of the plunger pump are met, thereliable operation of a water purification system is ensured, and a special working condition demand can be met.

Description

technical field [0001] The invention relates to a straight-flow plunger pump. Background technique [0002] During the third phase of the manned phase, the water purifier in the environmental control and life protection sub-system of the space station needs condensed water with a rated flow rate to participate in the purification, which requires that the flow rate of the liquid is always in a constant flow state and cannot be affected by the post-stage reactor and other equipment. , that is, it is required that no matter how much the post-stage pressure at the output end changes, the output liquid volume of the liquid supply device cannot fluctuate greatly. The plunger pump has high volumetric efficiency, low flow rate and stable flow output, high head, and pressure changes hardly affect the flow rate. It can realize accurate and quantitative delivery of low-pressure to high-pressure water media to meet task requirements. [0003] Due to the complex structure of the plunger...
