Detailed Description
The present application is described in further detail below in conjunction with fig. 1-3.
The embodiment of the application discloses incessant water supply system of secondary working shaft room.
Referring to fig. 1 and 2, the uninterruptible water supply system for the secondary water supply pump house includes a constant-pressure water supply control cabinet 1 disposed in each area and a frequency converter group 2 disposed in the constant-pressure water supply control cabinet 1, wherein the frequency converter group 2 includes a main frequency converter 21 and a standby frequency converter 22 connected to the water pumps one by one, and the main frequency converter 21 and the standby frequency converter 22 are respectively connected to a power supply 3.
It should be noted that, high-rise buildings are generally supplied by zones, and generally divided into a low zone, a middle zone and a high zone, a constant-pressure water supply control cabinet 1 is arranged in each zone, the constant-pressure water supply control cabinet 1 adopts a full-frequency conversion control mode, that is, when one main frequency converter 21 fails, the standby frequency converter 22 is automatically put into operation, and the full-frequency conversion mode has no secondary control loop with a single-frequency conversion mode, so that the secondary loop failure can be reduced to the greatest extent.
In addition, the constant-pressure water supply control cabinet 1 adopts a standby PID mode, and when the main PLC module fails, the standby PID mode is automatically switched to control the standby unit to operate. The standby frequency converter 22 is connected with the independent power supply 3, and when the main frequency converter 21 has a problem, the standby frequency converter 22 is not affected and can be immediately put into operation.
Because the constant pressure water supply control cabinet 1 of every subregion is responsible for gathering the control signal in each district to send to the constant pressure water supply control cabinet 1 of least significant district, upload to secondary water supply monitoring platform 4 by the constant pressure water supply control cabinet 1 of least significant district, this mode leads to equipment trouble in arbitrary one subregion or just influences the normal operating of the constant pressure water supply control cabinet 1 of least significant district when overhauing.
In order to solve the problems, a pump room control cabinet 5 connected with the constant-pressure water supply control cabinets 1 of all the partitions is arranged, and the pump room control cabinet 5 is connected with a secondary water supply monitoring platform 4. The constant-pressure water supply control cabinet 1 of each subarea is only responsible for collecting control signals of each subarea, sending the control signals to the pump room control cabinet 5, uploading the control signals to the secondary water supply monitoring platform 4 through the pump room control cabinet 5, and effectively reducing the fault shutdown of the constant-pressure water supply control cabinet 1 caused by equipment faults.
