HYDRAULIC DRIVE WITH LS OF THE CONTROL AND MANIFOLD OF MOTORS
(pp. 55-58)

Abstract. Currently, multi enginehydraulic are widely used in production machines for various purposes. One possible way of innovative development is the use of space-throttle control method using pumps with control. For the multifunctional technological machines was developed by mnogodvigatel'nyj that this method of regulation precision on the basis of one LS-controlled pump. For example, a single plot of the hydraulic features of its structure and functioning. Calculation research of characteristics of the PC confirmed its efficiency and high energy efficiency. The value of efficiency reached 63 %, error in speed did not exceed 6 %. The design of hydraulic mnogodvigatel'nogo space-control throttle control allows for precise regulation of the working fluid consump-tion, reduces pressure loss, demonstrates a significant energy saving. Use a pump with LS-control and pressure limiter ensures delivery of fluid to the desired pressure simultaneously to multiple Executive gidrodvigatelam. This simplifies the design of transmission working machines and improves their physical characteristics.
