電動ポンプシステムおよび電動ポンプ交互運転制御装置
Document Type and Number:
Japanese Patent JP6794234
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrically-driven pump system capable of changing-over an operation of the electrically-driven pump between an automatic operation and a manual operation that enables discharging water to be carried out appropriately even if the operation of the electrically-driven pump is changed over to the manual operation and left at its state.SOLUTION: This motor-driven pump system 100 comprises several submerged motor-driven pumps 3a, 3b; a water level detecting part 4 for detecting a water level at an area where water is discharged; and a control device 1 for alternatively operating several submerged motor-driven pumps 3a and 3b on the basis of the water level detected by the water level detecting part 4. Then, the control device 1 enables operation of the submerged motor-driven pumps 3a and 3b to be changed over between automatic operation and manual operation and the control device is constituted in such a way that the operation of the submerged motor-driven pumps 3a and 3b can be changed over to the automatic operation on the basis of a detection of predetermined water level performed by the water level detecting part 4 when the submerged motor-driven pumps 3a and 3b are set to a manual operation.SELECTED DRAWING: Figure 1
