Great advantage of the present utility model is to adopt S shape blade, design no stator, cantilever structure, by changing the stator phase of submersible motor, makes the forward and reverse rotation of motor and water pump, realizes two-way functional requirement of drawing water.S shape blade type bidirectional submersed three-flow pump structure of the present utility model is easy, makes easily, and its cutting depth is low, and civilwork engineering quantity is little, and construction investment is low, and the unit efficiency height is particularly useful for the pumping station of low lift or special low lift, and has broad application prospects.
S shape blade structure of the present utility model, the turnover flow condition limit of its blade is relative, the S-shaped shape that reverses, and is a kind of blade structure that reverses shape that is.The S shape front side of vane and the back side have wave degree.After submersed three-flow pump adopts S shape blade, can realize that fluid presses the two-way flow of design discharge and lift.
Structure of the present utility model, after the calculating by runner diffusion angle and the analysis of turnover flow condition, adopt the design of no gate vane channel, can satisfy the stability requirement of blade water outlet current, also help realizing simultaneously the in a basic balance of forward and reverse pumping plant efficient.
The utility model is according to pump group calculation of bearing capacity, and the main shaft of its submersible motor and water pump adopt coaxial the connection and the structural design of cantilevered fashion, under the condition of no stator, have guaranteed the stability of pump group operation.
Description of drawings
Fig. 1 is the structural representation of a kind of blade type bidirectional submersed three-flow pump of the present utility model.
Fig. 2 is the S shape blade structure schematic representation in Fig. 1 through-flow pump.
Embodiment
Referring to Fig. 1, S shape blade type bidirectional submersed three-flow pump of the present utility model is equipped with complete machine cylindrical shell 1, settles submersible motor 2 in complete machine cylindrical shell 1, and submersible motor 2 is installed on the complete machine cylindrical shell 1 by connecting gusset 3, and submersible motor 2 is arranged at the centre of complete machine cylindrical shell 1.
The main shaft 21 of submersible motor 2 is coaxial and stretch out forward and form the shaft extension section with water pump, and this is a kind of structural design of cantilevered fashion, can guarantee that the pump group is stable.Combination bearing 4 is housed on the motor output shaft section, impeller base 5 and wheel member 6 is installed in the end of motor output shaft section.S shape blade 7 is housed on the wheel member 6, and impeller housing 8 is equipped with in the outside of wheel member 6, and wheel member 6 and S shape blade 7 rotate in impeller housing 8.
The shell front end of submersible motor 2 is settled guiding cone 9, and these guiding cone 9 surfaces are not provided with stator, adopt no stator form, and, make current evenly spread (contraction) by outer flow passage diffusion angle, play the effect of current stabilization, and when making forward and reverse operation, unit efficiency is in a basic balance.Guiding cone 9 is positioned at the outer ring of motor output shaft section, and the other end of guiding cone 9 then joins with impeller base 5.At the outer ring of guiding cone 9 installing water conservancy diversion shell 10, water conservancy diversion shell 10 has the diffusion angle and does not have stator.One end of this water conservancy diversion shell 10 links to each other with complete machine cylindrical shell 1, and the other end of water conservancy diversion shell 10 then is connected with impeller housing 8.The device runner that complete machine cylindrical shell 1 is connected with water conservancy diversion shell 10 is diffusion or shrinks molded lines.
Mechanical sealing base 11 and mechanical seal 12 are housed, so that the combination bearing 4 that is installed on the motor output shaft section is sealed on the main shaft 21 in guiding cone 9.
Front end at impeller base 5 is equipped with the little cover 13 of water conservancy diversion, and it can make the current in positive flow influent stream road flow into blade smooth-goingly.The big cover 14 of water conservancy diversion is installed in the rear end of submersible motor 2, and it can make the current that reversely flow into runner lead to flow in the runner between submersible motor 2 and the complete machine cylindrical shell 1 smooth-goingly.
Water inlet Taper Pipe 15 is settled in the place ahead of impeller housing 8, between water inlet Taper Pipe 15 and the impeller housing 8 slip joint 16 can be installed.Water outlet straight tube 17 can be installed in the rear end of complete machine cylindrical shell 1.These intake pipes and outlet pipe have formed water flow passage.
The circular housing of submersible motor section is an anisodiametric truncated cone shape cylindrical shell, not only can reduce the diffusion angle of Taper Pipe section, and impeller to the angle of flare of outlet passage is changed evenly, helps flow-shape, reduces hydraulic loss.
Referring to Fig. 2, this is a kind of S shape blade 7 in the utility model, for the S-shaped structure of reversing shape, is installed on the wheel member 6.In this submersed three-flow pump, adopt S shape blade, utilize the change of blade sense of rotation, realize the two-way flow of fluid.
The pump water process of bidirectional submersed three-flow pump of the present utility model is as follows:
When submersible motor is rotated in the forward, current flow into from a current mouth forward of the runner of water inlet pool, enter wheel member, obtaining energy by S shape blade flows out, pass through in the runner of fluid between water conservancy diversion shell and guiding cone, change because outer flow passage spreads the angle of (contraction) gradually, reduce flow velocity, favourable recovered energy.Gusset between complete machine cylindrical shell and submersible motor can play the effect of long guide vane, helps eliminating the rotation of current, forms following current after the motor side water outlet, flows out through outlet passage current direction water outlet pool mouth.
Otherwise, when the submersible motor counterrotating, current oppositely flow into from another current mouth of runner, fluid is introduced in the runner between complete machine cylindrical shell and the submersible motor and in the runner between water conservancy diversion shell and the guiding cone, because the motor gusset is thinner, without hindrance substantially to current, and good leading role is arranged.Current obtain energy under the counterrotating effect that is positioned at motor back S shape blade, flow out from the little cover end rotation of water conservancy diversion, and the big runner that directly enters the band angle of flare flows out.
The utility model realized two-way drawing water by the above-mentioned method of operation, but but played the remarkable efficacy of not only draining but also diversion.
