Submersible sewage pump flow options

Submersible sewage pump flow options:
1, when there is displacement adjustment, according to the maximum drainage flow of life selected. The flow rate of the drain pump in the fire elevator collection tank is not less than 10L / s. Submersible sewage pump lift according to the height of the increase, pipe loss calculation to determine, and then add a certain free head. Free head should adopt 0.02 ~ 0.03MPa. Submersible sewage pump suction pipe and outlet pipe flow rate should not be less than 0.7m / s, and should not be greater than 2.0m / s. Public buildings should be in each living drainage pool as a unit to set up a spare pump, usually should be interactive operation. Basement, equipment room, garage rinse the ground drainage, if there are two or more submersible sewage pump can not be equipped with a pump.
2, when the pool can not set the accident drain, the pump should have uninterrupted power supply;
3, when you can close the drainage pipe, you can not supply uninterrupted power supply, but should set the alarm device.
4, when the increase with a large impurity of sewage, waste water, different sump within the submersible sewage pump outlet pipe should not be combined discharge.
5, when the general increase in waste water, according to the actual situation to consider the different pool of submersible sewage pump out of the water pipe combined discharge. When two or more pumps share a water outlet, install valves and check valves on each pump outlet pipe. Single pump drainage may produce a backflush, should be set to check valve. Do not allow pressure drainage off and the surrounding gravity drainage pipe combined with the discharge.
6, when the submersible sewage pump to enhance the containment of large debris, the submersible sewage pump should be equipped with a crushing device; when lifting more fiber containing sewage, it is appropriate to use large channel submersible sewage pump.
7, when the motor power is greater than or equal to 7.5kW or outlet diameter greater than or equal to DN100, the pump can be fixed self-coupling device;
     8, when the submersible sewage pump motor power is less than 7.5kW or outlet diameter is less than DN100, can be installed hose mobile installation. Sewage collection pool with submersible sewage pump drainage, water pump should be fixed self-coupling device to facilitate water pump maintenance. Drain pump should be able to automatically start and stop and on-site manual start and stop. Multiple submersible sewage pumps can be run alternately in parallel, can also be put into operation.
