Supply of hydraulic submersible pump emergency drainage dredging

Hydraulic submersible drainage emergency dredging pumps, inlet and outlet pipe are connected to both ends of the dredging pump body, and connected to the power drive unit located within the outlet pipe and dredging pump body, power-driven device as a hydraulic motor, the hydraulic motor the output shaft through the coupling body and dredging pump shaft, and the connection of the hydraulic motor and the dredging of the pump body is provided with a sealing device. Thus, the output shaft of the hydraulic motor shaft and the dredging of the pump body through the coupling connection, and a sealing device in the vicinity of the coupling, so that the coupling is formed around a closed cavity, can prevent debris from entering; At the same time, it is not the main power dredging pump power restrictions at any time, any place can be used for emergency drainage, dredging, dredge the river, without the urban areas of the power supply to the place of work, make the operation more convenient . Features: 1, the sealing means comprises a sealing cap at one end of the hydraulic motor flange connection, and through the first ring seal, the other end of the dredging pump body flange connection, and through a second ring seal; Union Axis is located within the enclosures. 2, on the side wall of the closure cap with a window, the window seal at the cover is connected to the closure cap and through the third ring seal. 3, inlet pipe connected to the water inlet filter decontamination equipment, decontamination apparatus including the filter filters, brackets and arc panel; filter connected to the inlet of the water inlet; brackets to two, each bracket by a horizontal bracket and oblique frame composition, end of the horizontal and diagonal scaffold bracket are connected to the filter, and the other end connected to each other after the welding arc panel. 4, the inner panel welding arc welding end mutual channel, horizontal and diagonal scaffold bracket welded inside the channel. 5, hydraulic submersible dredging emergency drainage pump installed in a small car, the car was tracked vehicles. Hydraulic submersible pumps Technical Field The invention relates to the technical field submersible pumps, specifically hydraulic submersible pump with an emergency drainage. Background Currently, emergency drainage device, using more driven by the asynchronous motor submersible pump, usually asynchronous motor output shaft to the input shaft of the pump. However, the submersible pump of this structure has the following drawbacks: 1) Because of this emergency drainage environment is very bad, usually used after the flood emergency drainage, while asynchronous motor driven submersible pump is greatly limited power supply, After the flood, there is no power supply to power use, causing drainage can not rescue; at the same time, work is generally in the field drainage river, next to the river carried from the distance from downtown, it is difficult to quickly to urban areas The power supply to the drainage sites, thus affecting the drainage rescue time; 2) In addition, because after the flood, will accumulate silt and other debris in the riverbed, and submersible pumps in the prior art only provided the water inlet filter When such encounter these silt and other debris and can not be arranged, so that filtered decontamination effect is not strong, or even hinder water; 3) In addition, since the submersible pump in the river bed is to be moved, and the existing technology uses asynchronous motor driven submersible pumps are bulky, so inconvenient to move; at the same time, submersible pump placed directly on the river bed, the contact area with the bed of a small submersible pumps, easily the whole stuck in the mud in the river bed. The utility model technical problem to be solved is to provide a driven by a hydraulic motor, so that the power supply is not limited, and can be used anywhere drainage and rescue work, and small size, high efficiency hydraulic submersible pump unit.
