SUBSTANTIATION OF THE NEED TO CREATE DISCRETE HYDRAULIC DRIVE SYSTEMS WITH A THIN FORMATION OF FLOW PULSES

Abstract

The creation of machines for heavy mining conditions is impossible without solving the problems associated with the drive. The widely  used hydraulic drive has a number of drawbacks that can not make it uniquely acceptable. More successful is the electric drive, which  takes advantage of the stepping electric drive, but its scope is  limited by the parameters of the hydraulic motors. That is why it is  necessary to create a so-called discrete hydro motor drive that  would allow generating pulses of small volumes with high  frequencies to move the output links to specified distances with high accuracy in a wide range of speeds. This determines the relevance of the scientific and practical task under consideration. Conclusion: the  use of dispensers will allow the implementation of discrete hydraulic drive systems, but for its final implementation it is necessary to  justify the dynamic and geometric parameters of the device, as well as circuit solutions for the use of such dispensers.
