High-efficiency three-cylinder fine ceramic plunger pump

Abstract

The invention relates to a high-efficiency three-cylinder fine ceramic plunger pump which is characterized by comprising a water inlet valve choke plug, a water inlet cushion block, a water inlet valve assembly, a pump head, a water outlet valve assembly, a water outlet valve choke plug, a water seal, a secondary water seal, a crank case, a crank, a rear cover, an oil pointer, an oil-releasing screw, a ceramic plunger connecting rod component and an oil seal; the pump is characterized in that mechanical energy is converted into water flow pressure energy; with the help of a crank connecting rod mechanism, power is used for converting a rotating motion of the crank into a reciprocating motion of the plunger; when the plunger retreats, under the action of a vacuum absorbing force, a water inlet valve is opened, a water outlet valve is closed and water is sucked into a cylinder; and when the plunger moves forwards, water pressure in the pump is increased, so that the water inlet valve is closed, the water outlet valve is opened and high-pressure water is drained from the water outlet valve through a high-pressure pipe. The pump provided by the invention is used for efficiently solving the long-term existing problems of a plunger pump, such as oil leakage, inferior corrosion resistance, short service life, and the like. The pump provided by the invention has the advantages of high manufacturing precision and hardness, excellent corrosion resistance, smooth surface, capability of prolonging service life of a sealing piece, compact structure, small volume, light weight and reliable work.

Description

Technical field [0001] The invention relates to a high-efficiency three-cylinder fine ceramic plunger pump Background technique [0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize oil absorption and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, and is widely used in high pressure, large flow and flow adjustment occasions, such as hydraulic presses, engineering machinery and ships. [0003] Piston pumps are divided into two representative structural forms: axial piston pumps and radial piston pumps; since radial piston pumps are a new type of high-efficiency pump with relatively high technical content, with the continuous acceleration of localization , the radial piston pump will inevitably become an important part of the applic...
