Hydraulic Switching Control Supplementing Speed Variable Hydraulic Drives [PDF]
Actuators, 2020 Primary control of linear motion by variable speed electric motors driving a hydraulic cylinder via a constant displacement pump is an established and successful concept with a frequent use in industry. One problem arises when low or zero motion speed has to be realized under high pump pressure conditions.

Performance of SR Drive for Hydraulic Pump [PDF]
Journal of Electrical Engineering and Technology, 2007 This paper proposes a hydraulic pump system that uses a variable speed SR drive and constant capacity pump. For the design of the SRM (Switched Reluctance Motor) and digital controller, base speed and rating torque are determined from the mechanical specifications of the hydraulic pump.

Hydraulic shock suppression mechanism of the hydraulic drive [PDF]
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Researches show that hydraulic shock provokes premature destruction of hydraulic drive high-pressure hoses and unauthorized emission of working fluid into the atmosphere, resulting in environmental pollution. There are ways to protect the machines hydraulic transmission based on the principle of automatic disconnection from the ...
