There is specific literature record in the following contents.
The gate of traditional pump lock is pumped usually using tubular through flow pump or submersible axial flow pump, applicants have found that: this pump
Gate is connected across gate hole, since traditional tubular through flow pump uses the structure of submerged axial-flow pump type, this structure is in order to make perfusion
The outlet pipe of pump and water inlet pipe bore cannot differ too big because difference cause greatly very much fluid reached after blade accelerates guide vane into
Mouthful, and vane inlet is the diffuser being mutated to guide vane outlet, high-velocity fluid makes flow field fluidised form mixed when passing through mutation space
Disorderly, it is easy to produce turbulent flow when, to reduce the efficiency of water pump, in order to reduce influence caused by this phenomenon, leads to design of electrical motor
It obtains very long (not only thin but also long).Center is difficult to equilibrate to the vertical fortune of gate when being mounted on pump among gate
Dynamic center；Because pumping main weight on motor, pump will lead to again when motor side is centrally fixed to shutter motion center
Hold cantilever amount too long, when gate starts or be closed moment, the impact of pump end is very big, often results in casting fracture or sealing surface
The phenomenon that instantaneous infiltration.
Traditional gate pump uses the structure being of coupled connections: when tubular through flow pump or submersible axial flow pump are coupled in the side of gate,
Cause center of gravity and the motion profile of gate eccentric serious, gate rise close when, it is strong that gate and gate slot occur for the side of weight
Friction.So that the seal life of gate substantially reduces；Simultaneously as pump is the coupled structure of not Complete Bind, pump is being transported
It is past when positive suction nozzle pressure is greater than 1.5 meters along with the positive suction nozzle pressure of pump inlet due to the reaction force by water when row
Toward the gravity that recoil strength can be made to be greater than pump in longitudinal component, pump is made to suspend, causes pump vibration serious, while generating sucking
Mouth backflow phenomenon, greatly reduces the operational efficiency of pump, due to vibration, also greatly promotes the probability of failure of pump.
Applicant has found through numerous studies: traditional axial flow pump has the disadvantage in that
(1) electric machine structure is long and narrow causes whole pump configuration long and narrow, and horizontal component each in gate is all cantilever position, does not prop up
Support is easy to happen the leak of casting junction or casting fracture when by shock loading.
(2) outlet of the import of guide vane to guide vane is the diffuser of taper mutation, and fluid adds through blade
Reach vane inlet after speed, high-velocity fluid makes flow field fluidised form chaotic when passing through mutation space, when be easy to produce turbulent flow, to reduce
The efficiency of water pump.
(3) when tubular through flow pump or submersible axial flow pump are coupled in the side of gate, cause the center of gravity of gate and motion profile inclined
The heart is serious, gate rise close when, the side of weight makes gate and gate slot that strong friction occur.So that the seal life of gate is big
It is big to reduce.
(4) it due to the coupled structure that pump is not Complete Bind, pumps at runtime, due to the reaction force by water, then
In addition the positive suction nozzle pressure of pump inlet often makes recoil strength be greater than the gravity of pump vertical when positive suction nozzle pressure is greater than 1.5 meters
To component, so that pump is suspended, cause pump vibration serious, while generating suction inlet backflow phenomenon, greatly reduce the fortune of pump
Line efficiency also greatly promotes the probability of failure of pump due to vibration.
(5) structure of conventional pump is more complicated, and the components of whole pump are very more, and manufacture processing capacity is very big, manufacture energy consumption
Also very high；It pumps simultaneously and needs the junction that seals also very more, the risk leaked while at high cost is also very high.
