The Study On Technique About The Key Part Of The Light Hydraulic Piston Pump Controlled Integratly

Axial piston swash plate hydraulic pump has the structure urgent, small radial size, moment of inertia, higher rotate speed, big flow, easy variable displacement, and can adjust automatically displacement with multi-way. As stated above, axial piston swash plate design pump is widely used for aircraft, shipping, engineering machinery, lifting transport, metallurgy ect.With the fast development of national defence and country economy, the number of hydraulic piston pump used keeps increasing. Its bound for use is also extended at present. The requirement of performance and quality for hydraulic pump is getting better and better.L10V series integration control hydraulic piston pump is the series variable displacement pump that Liyuan company has successfully developed base on the development of international hydraulic pump and absorbing overseas congeneric production technic. The series hydraulic piston pump is used for open loop circuits, nominal pressure-28Mpa, peak pressure-35Mpa; The ways of control have pressure control,pressure and flow integration control,pressure flow and power integration control and remote pressure control etc. For being advanced configuration and two-bit price, the series hydraulic piston pump is widely used for agriculture machinery,little engineering machinery,camion etc .Liyuan company is a big time enterprise engaged in developing and designing hydraulic pump/motor at home. Taking of the existing scientific research foundation and manufacture facility, our company has a powerful capability in developing the fire-new hydraulic piston pump. This article takes new integration control hydraulic pump to be developed as a question and will explore and research it in design and the key part technics.
