Abstract

The invention provides a self water-replenishing flat valve plunger type extra-high pressure water pump, which mainly comprises a cavity, a cooling unit, a rotating main shaft and a plunger flow-distribution unit. The cooling unit comprises a cooler and a water-replenishing pump; and the plunger flow-distribution unit comprises a flat valve component and a plunger skid shoe component. The plunger skid shoe component divides the cavity into a pressure chamber and an oil lubrication chamber which are independent from each other. The water-replenishing pump presses water at a water pump inlet into the cooler under the drive of the rotating main shaft, then the water flows into the flat valve component from the cooler to cool the oil lubrication chamber and provide low-pressure pressure water for the flat valve component, and simultaneously, the plunger skid shoe component performs reciprocating motion under the drive of the rotating main shaft to ensure that the flat valve component performs water absorbing and draining motions through the water pump inlet and a water pump outlet. The self water-replenishing flat valve plunger type extra-high pressure water pump solves the problems of over-high lubricating oil temperature and insufficient self-adsorption when an oil-water separation type hydraulic pump is used on shore, thereby reducing the running cost and improving the service life of the water pump.

Description

technical field [0001] The invention relates to the field of displacement pumps, in particular to a self-supplementing water pump with a valve-distributing plunger and an ultra-high pressure water pump. technical background [0002] Water hydraulic pump has been studied as a key technology in water hydraulic technology. Compared with mineral oil, water has a big difference in physical and chemical properties, such as the viscosity of water is small, the thickness of water film is thin, and the corrosion is large, which increases the difficulty of sealing and lubrication. [0003] Due to the physical and chemical characteristics of the water medium itself, the current international water pressure pump mainly adopts the plunger structure, such as the Nessie (Nice) series water pump produced by Danfoss (Danfoss) in Denmark, and the Hauhinco (Hausenko) water pump in Germany. And the seawater pumps produced by Komatsu Studio in Japan are all plunger pumps. Because the plunger p...
