WATER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2022003230
Kind Code:
A
Abstract:
To disclose one example of a water supply device capable of suppressing the occurrence of cavitation.SOLUTION: When it is determined that a detected suction pressure is less than a first predetermined pressure PS1 (S2:YES), a control unit activates a second electric pump P2 (S3). Consequently, when the second electric pump is activated, a discharge flow rate of a first electric pump is reduced, so that the occurrence of cavitation in the first electric pump can be suppressed.SELECTED DRAWING: Figure 2
