Hypertonia, the first access 12 are easy to appear risk of rupture, and therefore, the pump pressure that controller 5 controls sewage pump 14 declines and is equal to
Predetermined maximum sewage is pumped safety value.Wherein, making a reservation for maximum sewage pump pressure safety value is the highest for preventing the first access 12 from rupturing
Pressure, predetermined maximum sewage pump pressure safety value can be preset in the controller 5.
When controller 5 judges that sewage pump pump pressure is less than predetermined minimum sewage pump pressure value, illustrate that filter 18 may at this time
Blocking occurs and causes most of sewage can not be by sewage pressure detector 17, controller 5 opens 181 pairs of flush loop filterings
Device 18 is rinsed, and the impurity in filter 18 is washed out, and guarantees sewage smooth outflow in the first access 12.Predetermined minimum
Sewage pump pressure value can be preset in the controller 5.
Further, waterpower adjustment method further include:
Controller 5 obtains process water pump pump pressure.For example, process water pressure detector 36 measures the work of alternate path 32
After skill is pumped with water pump, process water can be pumped into pump pressure and be transferred to controller 5.
When controller 5 judges that process water pump pump pressure is greater than predetermined maximum 33 pressure safety value of process water pump, at this time the
The hypertonia of two accesses 32, alternate path 32 are easy to appear risk of rupture, and therefore, controller 5 controls process water pump 33
Pump pressure, which drops to, is equal to predetermined 33 pressure safety value of maximum process water pump.Wherein, make a reservation for maximum 33 pressure safety value of process water pump
For the maximum pressure for preventing alternate path 32 from rupturing, predetermined 33 pressure safety value of maximum process water pump can be set in advance in control
In device 5.
Specifically, waterpower adjustment method further include:
Controller 5 obtains the wastewater level height in sewage transfer puddle 1.For example, process water position meter 19 measures sewage
After the wastewater level height in transfer puddle 1, the wastewater level height in sewage transfer puddle 1 can be transferred to controller 5.
Predetermined water level height is to guarantee minimum of the row in sewage transfer puddle 1 with sufficient amount to sewage treatment terminal 41
Volume, predetermined water level height can be preset in the controller 5.When controller 5 judges that wastewater level height is greater than or equal to
When predetermined water level height, illustrate that the sewage in the puddle of sewage transfer at this time 1 passes through 12 row of the first access to sewage treatment terminal enough
41, controller 5 controls sewage pump 14 and opens.
When controller 5 judges wastewater level height lower than predetermined water level height, illustrate the dirt in the puddle of sewage transfer at this time 1
Water is not enough to through 12 row of the first access to sewage treatment terminal 41, and controller 5 controls sewage pump 14 and closes, to prevent sewage pump
14 idle running, save energy consumption.
