摘要： PROBLEM TO BE SOLVED: To electronically attenuate essential variation factors of pump torque for generating motor torque output to maintain output pressure from a pump constant.
SOLUTION: Disclosure is made of a precision hydraulic energy delivery system that directly couples the pump to a primary power source (motor) and a related motor control. The system provides flow control of a hydraulically driven machine without the use of downstream devices by employing motion control algorithms in the motor control. Hydraulic pressure output in pump head simultaneously follows by employing motion control algorithms in the motor control. Control features are integrated into the system by using control algorithms and subroutines specifically developed for the control system coupled to the pump.

摘要： Disclosure is made of a method for electronic polar attenuation of torque profile for positive displacement pumps by a processor where the attenuated torque profile is compared with the shaft displacement angle of the pump input shaft. The processor then signals a motor to power a pump with the result of pumping at a constant pressure at the full range of the designed system flow volume. In addition to the attenuated torque profile, the processor can also account for the response time of the pump drive, the motor inductive reactance, system inertia, application characteristics of the pump, and regenerative energy during deceleration of the pump.

摘要： A filter backflushing system including an accumulator containing a pressurized bladder which propels a supply of backwash fluid contained within the accumulator in a reverse direction through a filter element. While the backwash fluid is pumped within the accumulator, an inert gas inside the bladder is compressed against the inside walls of the accumulator. Upon reaching a pressure of approximately 300-600 psi, the filtered fluid is released from the accumulator and the full energy of the compressed gas is released as well. This release produces a high pressure rapid burst of backwash fluid which effectively removes clogging contaminants from a filter element.
