Patent number: 6599095Abstract: A pump off control method comprises detecting the speed of the induction motor and an instantaneous value of secondary current of the induction motor. Down stroke time in every cycle of the pump jack is detected. An average value of instantaneous values of the secondary current of the induction motor in the down stroke time in said every cycle is calculated. An average value reference of the secondary current of the induction motor to be compared with calculated average value of the instantaneous values of the secondary current of the induction motor is set. The calculated average value of the instantaneous values of the secondary current is compared with the average value reference after the down stroke end in each cycle. An occurence of pump off is detected if the calculated average value of the instantaneous values is greater than the average value reference.Type: GrantFiled: October 29, 2001Date of Patent: July 29, 2003Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Noriyuki Takada, Takayuki Yamakawa, Hidetoshi Ryu, Tetsuo Kawano, Koji Kawamoto, Toshio Miyano, Richard L.

Patent number: 5488787Abstract: When a prime mover (1) is driven, a controller (25) outputs an open-drive signal for bringing an opening/shutting valve (23) into an open position and, upon a control lever (68, etc.) being operated, a hydraulic fluid is supplied from an auxiliary hydraulic pump (7) through pressure reducing valves to driving sectors of directional control valves (8 to 16) for shifting them. A flow rate and a direction of flow of the hydraulic fluid from main hydraulic pumps (3, 4) are thereby adjusted so that actuators (57A, 57B, 57C, 56A, 54) can be each operated at a speed depending on the amount by which the control lever is operated. When one of the actuators (57A, 57B, 57C, 56A, 54) is to be driven when the prime mover (1) is not driven, an open command is selected in a selection command device (24), whereupon the controller (25) outputs the open-drive signal, causing the opening/shutting valve (23) to open a line interconnecting the accumulator (21) and the pressure reducing valve (17), etc.Type: GrantFiled: August 3, 1994Date of Patent: February 6, 1996Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Yukio Aoyagi, Kazuhiko Otsubo, Gen Yasuda, Koji Fujita, Takayuki Yamakawa, Kazuyoshi Narita
