Road 12, low level media storage container outlet conduit 12 are connected to centrifugal pump inlet pipeline 13, low level media storage container outlet
Set on road 12 and draw flow container 10, drawn the horizontal level of flow container 10 and be higher than the horizontal level of centrifugal pump 5, draw flow container 10 and centrifugal pump inlet pipe
Ball valve 9 is set on the low level media storage container outlet conduit 12 between road 13.Centrifugal pump 5 connects inlet duct 13 and outlet
Road 14, centrifugal pump inlet pipeline 13 connect high-order media storage container 1, and the high-order horizontal level of media storage container 1 is higher than centrifugation
The horizontal level of pump 5, inlet porting ball valve 2 and entrance drain valve 3 on centrifugal pump inlet pipeline 13, Inlet ball valve 2 are arranged on entrance
For pipeline 13 close to one end of high-order media storage container 1, entrance drain valve 3 is arranged on inlet duct 13 close to the one of centrifugal pump 5
End；The low level media storage container outlet conduit 12 is arranged between Inlet ball valve 2 and entrance drain valve 3；The centrifugal pump
Vent ball valve 8 and outlet drain valve 6, outlet drain valve 6 is set to be arranged on outlet conduit 14 close to centrifugal pump 5 on outlet conduit 14
One end, vent ball valve 8 is arranged on the one end of outlet conduit 14 away from centrifugal pump 5.The volume for drawing flow container 10 is set more than centrifugal pump 5
Count flow 0.5 times, make to draw the negative pressure that formation is sufficiently large in flow container 10, it is convenient to suck liquid.The low level medium of connection ball valve 9 is deposited
The nominal diameter of storage container outlet conduit, material, pressure rating are identical with centrifugal pump inlet pipeline 13, and flow container 10 and ground are drawn in connection
Nominal diameter, material, pressure rating and the phase of outlet of centrifugal pump pipeline 14 of the low level media storage container outlet conduit in ditch pond 11
