Further, multiple exit branch are additionally provided with the water exit end of the outfall sewer.
Before equipment opens pump, the control module programme-control water pump exhaust electromagnetism first in constant pressure water supply control device
Valve is opened, and carries out water pump exhaust, and switch off the pump exhaust solenoid valve after a period of time that is delayed；Then liquid level sensor collection water box liquid
Position signal passes to control module, and control module gathers the pressure of outfall sewer according to discharge pressure sensor, with default
Pressure is compared, when high water tank meets to open pump condition, and outfall sewer pressure is less than setting pressure, control module control
Frequency control module drives the operation of water pump Full-automatic variable-frequency.
The present invention remarkable result be：The system changes water pump, and manually exhaust is vented for procedure auto-control, effectively solves
Because pipeline pneumatosis cavitates influence caused by water pump, equipment failure rate is reduced, extends service life of equipment.
