Title: Method and device for controlling drive motor of gradual drive pump
Inventor: PIITAA JII UIIRUDAN
IPC: A61M5/14
Filed: 1984-05-04
Abstract: Control apparatus for a stepping motor driving a peristaltic pump comprises a presettable downcounter for supplying drive pulses to the stepping motor at different repetition rates so as to regulate the speed of rotation of the motor, processing means for controlling the downcounter so that the motor is normally operated to drive the pump at a predetermined pumping rate, and a sensor for detecting indexing marks at spaced positions about the pump head, the processing means being responsive to the sensor detecting the index marks to alter the count in the downcounter so as to increase the motor speed for a predetermined number of motor steps upon detection of each index mark. After the predetermined number of steps at increased speed, the processing means resets the downcounter to its normal setting, so that the motor operates at the required pumping rate for a further predetermined number of motor steps and until detection of the next successive index mark of the head. Hence, the drive motor rotates or skips more rapidly during alternate periods corresponding to dwell periods of the peristaltic pump when reduced or no fluid flow would normally occur and, consequently, the pump delivers fluid at a more constant flow rate.

Abstract: PURPOSE:To stop any possible leakage easily and safely in a short time by crushing the upstream side of a leaking part in a pipeline, making this crushed part form a passage successively into narrowness in the downstream direction, and decompressing a fluid by this crushed part, then attaching a closing member to the pipeline, finally stopping any leakage of the fluid. CONSTITUTION:When a leak has happened in a branch pipe 2d, by way of example, installed in a main pipe 1, this branch pipe 2d is crushed at its A position from the outside, forming a crushed part 12a which is made up over plural stages at the upstream side of the leaked part of a pipeline, and each of four crushed parts 12a-12d is contracted as far as more than for example, 50%, 70%, 80-90%, 95% in each inner diameter, thus they are formed into narrowness successively in proportion as going in the downstream direction. A fluid is decompressed by an orifice function by means of these crushed parts, and a valve 5 of a closing member is installed at the upstream side of the leaked part, thereby stopping any leakage of the fluid. In consequence, sealing repair can be easily done in a short time without incurring any production loss, as leaving the fluid live intact.
