Abstract
PURPOSE: To attain reduction of labor through automatization and conservation of energy through optimum operation by knowing load states of several fluid compression feeding equipments from variables of pressure and the quantity of flowing water and then by exercising automatic and optimum damping and stop control corresponding to the load states.
CONSTITUTION: Pressure P and quantity Q of flowing water of fluid compression feeding equipments 2aW2d supplying a fluid to load 1 are detected by pressure transmitter 4 and flow transmitter 5 and a detected analog signal is converted into a digital signal by AD converter 7 of computer system 6. This signal is applied to CPU8 to calculate variables of pressure P and quantity Q of flowing water or mean movement values, which are compared with a normal value needed for operation by input information from operation board 22; when the calculation value is lower, equipments 2aW2d in stop mode are selected and actuated and when higher, the total sum of maximum supply volumes of equipments 2aW2d in motion is subtracted from the calculation value to obtain its excessive volume. Then, the excessive volume is sequentially compared with the maximum supply volumes of equipments 2aW2d to stop the supply of the excessive volume.
