Title:
PUMP CONTROL
Document Type and Number:
Japanese Patent JP3662605
Kind Code:
B2
Abstract:
PURPOSE: To enable the rotary running of total four sets of pumps in a plurality of controllers for respectively controlling a plurality of pumps by controlling the running of the pump on the basis of the respective data of the number of the running pumps, the presence of standby pump, the pump set increasing and decreasing inhibiting command and the like.
CONSTITUTION: Two control parts 31, 32 control respectively two motors for driving respectively two pumps and are connected to each other through a communication line while respective running data a1, b1, a2, b2, respective pump unit increase inhibiting data c1, c2 and respective pump unit reduction inhibiting data d1, d2 are transmitted between these controlling parts. The running of the pump is controlled on the basis of the respective data. For example, as far as the respective running data a1, b1, a2, b2 are concerned, (1, 1) when two pump units are run, (1, 0) when one pump unit is run, (0, 1) when the pump is stopped and (0, 0) when the standby pump is absent are respectively outputted, so that the rotary running of total four pumps is also made possible.
