Substantiation of the need to create discrete hydraulic drive systems with a thin formation of flow pulses

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.
