Abstract
The present invention relates to a volumetric pump especially suitable for pumping high-pressure sea water, fresh water and other low-viscosity liquid. The pump has fluid distributing valve with soft sealing structure, plunger with reliably separated oil and water at the two ends and main friction pair lubricated with lubricating oil. The pump has simple structure, good suction property, reliable operation and high efficiency. It may be used as the main pump in medium and low pressure hydraulic system with sea water, fresh water and other low-viscosity liquid as working medium, the drainage pump in deep sea work boat, submarine, lifeboat and other ships, fire-extinguishing pump for high-rise building, etc.
Description
The invention belongs to positive displacement pump or oil hydraulic pump, be specially adapted to the occasion of pumping high pressure sea water, fresh water and other low-viscosity (mobile) liquids.
The hydraulic system that is widely used in each industrial department at present mainly adopts mineral oil to make the work medium, has both wasted petroleum resources, and shortcomings such as inflammable, befouling environment are arranged again.Therefore, developing the oil hydraulic pump of making the work medium with seawater or fresh water proxy mineral oil in the world, seawater, the fresh water oil hydraulic pump of foreign latest development adopt valve plate distribution and piston shoes-oblique disk structure more, (the Hydraulic Components Using TapWater as Pressure Medium that for example " makes the hydraulic element of work medium with pure water ", Erik Trostmann etc., The Forth ScandinavianInternational Conference on Fluid Power, Tempere, Finland, Sep.1995); And for example " selection and the performance thereof of sea water hydraulic pump ceramic part " (The Selectionand Performance of Ceramic Components in a Sea-Water Pump, C ABrooks etc., Fluid Power Proceedings of Third JHPS InternationalSymposium on Fluid Power, Yokohoma 96, Japan, 1996), " latest development of Hydraulic Drive Technology " for another example (Development in Water Hydraulics, G.Scheffels, Hydraulic and Pneumatics, USA, Dec, 1996) etc. all adopt valve plate distribution and piston shoes-oblique disk structure, main friction pairs all is immersed in the water.Because the corrosivity of water, particularly seawater is big, poor lubricity, the PV value that in addition acts on friction pair is big, therefore can not use the common metal material, mainly adopts special engineered materials such as engineering ceramics.Go back simultaneously because of complex structure, processing difficulties, the cost height if particularly do not have novel engineering material of this class and non-traditional machining means, is difficult to finish the manufacturing of this class pump and apply.
