Description
Technical field
The utility model relates to a kind of high-pressure multi-stage Double Channel Pump.
Background technique
Deep sea mineral resources (as oceanic multi-metal nodule, cobalt bearing crust and Polymetallic sulphide etc.) belongs to oarse-grained category, large particle Non-blinding pump, why for deepsea mining system, is because its feature should possess high-lift, low discharge, high-power and by advantages such as large particles; Simultaneously motor need to have sealing withstand voltage, insulate and prevent the ability of seawater corrosion.Obviously, this development at high-pressure undersea underwater operation Submerged Motor Pumps is the new and high technology that a difficulty is large.
At home, in outer deep-sea mining large particle vertical pipe Hydraulic transportation technology, practitioner is all had to develop development to large particle Non-blinding pump.But in existing large particle Non-blinding pump, there is pump blocking phenomenon in its pump runner design but existing defects in particle ore pulp lifting test, and the main cause causing pump to block is the ring grille runner in pump.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simplicity of design, high efficiency and can meets the high-pressure multi-stage Double Channel Pump of large particle vertical pipe Hydraulic transportation.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of high-pressure multi-stage Double Channel Pump, comprise shell and inner casing, described shell is wrapped in inner casing, outer annular channel is provided with between described shell and inner casing, described inner housing inner is provided with interior annular pass, described inner casing is provided with the pod apertures run through, described pod apertures is communicated with outer annular channel and interior annular pass, described interior annular pass is provided with auxiliary impeller, described impeller is provided with motor, described inner casing one end is connected with the water intake running through shell, the other end is provided with outlet conduit, described outlet conduit is connected with multistage pump, described multistage pump includes main shaft and more than one water pump, described multistage pump is connected with water outlet, described more than one water pump is arranged on main shaft both sides, described water pump includes impeller, guide vane, and housing, described impeller and housing adopt sealed member to be connected, described guide vane is arranged on housing.
As preferably, described shell and inner casing are Stainless Steel Shell, prevent shell and inner casing from getting rusty because of Long Term Contact water and oxygen.
As preferably, described pod apertures is provided with more than one, can arrange suitable pod apertures quantity according to actual needs.
