this design, water and oil system is to transfer the devices in detail, as is the use of the water pump and the water pump installed in the manhole to the moving vehicles according to external shock or stimulus to the protection function of the vehicle. the safety and facilitate can be realized. the operation of a pump in the form of the device.;the design of water pump and the suction side of the pump connected to the discharge port, and the discharge side of the pump is composed of pump, the water treatment device to the suction side of the pump, the connection of the connection, and a quarter of the form of the first manifold. the pass of the connection part and the connection and the suction and discharge side diameter is more than a quarter of the diameter of the pump tube and a branch tube; the shape of the tube, through the formation of the majority of the season, the uba74uc5d0 parallel installation of ship to open and the protection of a protection part and the pad through a branch pipe is connected to the branch connection is formed in the side of the pump, and a second link is attached to the manifold, the adapter includes structure.;so the research in this area, the protection of a manhole pumping operation and are part of the pressure in the tube is not damaged and the pumping work will facilitate the government, through the vehicle, and to minimize the occurrence of impact aggregate.
