VSeriesVanePump
■General Description
This pump is developed to meet the ever increasing demands for machine-tool industry application by our company. Total 5 series and 37 sizes are available, displacement range from 7.5 to 344 ml/r, maximum operating pressure 21 MPa and speed from 600 to 1800 rpm; intra-vane design enables the pump having high pressure, large capacity, compact size, low sound level and longer service life features; its main technical data reached to the advanced level of the same product in the world.
This series pump adopts replaceable pumping cartridge containing all parts that wear none contact the body. Field service can be accomplished without removing the pump from its mounting, eliminating the need for factory repairing which reduces expensive downtime; with hydraulic balance, bearing loads resulting from pressure are eliminated and the only radial loads are those imposed by the drive itself. Longer life and minimum maintenance are direct results; Wear compensation is inherent in the design. Intra-vane design which enables that continuously applied outlet pressure between vane and intra-vane reduces tip loading to the extent desired on a particular pump. Outward balanced thrust of vane inlet port area is equal to outlet pressure times projected area of end of intra-vane.To resist the cantilever loads of any practical outlet pressure, vane thickness can be increased without increasing load between vane and cam ring. The dual vane arrangement assures solid tracking of the cam ring throughout the pumping cycle. This means less leakage across vane tips which enhances volumetric efficiency, low noise and less cam ring wear.
Installation meet ISO/SAE standards; with complete specifications, reliable performance, reasonable construction and convenient installation and easy maintenance, it is widely used in hydraulic systems for machine-tools, presses, die casting machines, engineering, plastic injection moulding and other machineries.
