Description
Technical field
The invention belongs to submersible pump technical fields, and in particular to a kind of outer rotor submersed three-flow pump.
Background technique
Submersed three-flow pump is there are two types of structural shape, one is the submersed three-flow pump of traditional dry-type submersible motor adapted, one
Kind is impeller built-in submersed three-flow pump.
Dry-type submersible motor and the pump housing are relatively independent in the submersed three-flow pump of traditional dry-type submersible motor adapted, most
Distinguishing feature is that the structure of submersible pump is that dry-type submersible motor and immersible pump are coaxially connected, and dry-type submersible motor is placed in diving electricity
In the outlet passage of pump, the impeller of pump is on the water inlet side of unit.The impeller of pump pumps water flow, flows to water outlet by the outer wall of motor
In runner.Adapted dry-type submersible motor is all-sealed structure, and inner cavity is dry air.The submersible pump of this structural shape exists
Following shortcoming: firstly, submersible motor is submerged in water for a long time, the sealing of motor it is difficult to ensure that, especially in submergence
When in deeper water, the electric insulation of motor cannot reliably be guaranteed that there are security risks for dry-type submersible motor；Secondly, pump
Impeller be cantilever beam structure, i.e., only in the side of impeller have a bearing pivot.This structural requirement machining accuracy is high, simultaneously
Shock resistance is poor.Impeller easily forms the impeller outer shell phase wiping accident that each side gap is uneven, causes the impeller of rotation and fixes.
In addition, dry-type submersible motor is placed in outlet passage, it will affect the water outlet fluidised form of pumping water flow, directly affect the effect of submersible pump
Rate.Structure is complicated for former submersible pump, and axial length is longer, not easy to repair, open and inspect.
Impeller built-in submersed three-flow pump most distinguishing feature is that the impeller assembly of submersible pump is fixed on to Water diving
Rotor inner cavity is integrally formed formula rotor with Water-filled Type Submersible Motors rotor welding, and integral type rotor is located at Water diving
Inside motor stator, Water-filled Type Submersible Motors stator is fixedly installed in stator casing, and the axial ends of stator casing connects respectively
Suction chamber and water-supplying chamber are connect, forms simple, the compact impeller built-in submersed three-flow pump of a structure in this way.
In place of the impeller built-in submersible pump Shortcomings of the structural shape: because its integral type rotor (impeller assembly with
Water-filled Type Submersible Motors rotor) rotate in water, impeller assembly rotate in water generation frictional dissipation and common water pump just
Normal loss is suitable, and the frictional dissipation that Water-filled Type Submersible Motors rotor rotates generation in water is then increased loss.This
Friction loss is made of two parts: first is that the friction loss of Water-filled Type Submersible Motors rotor cylinder surface, 4 times of it and rotor radius
The length of side and rotor is directly proportional；Second is that the friction loss of rotor end-face, it is directly proportional to 5 powers of rotor radius.And cylinder
The friction loss in face is approximately 2 times of end face friction loss, and the fricting loss power on the cylindrical surface of rotor can be damaged by disk friction
The formula of mistake comes.
The hydraulic friction wasted power of periphery can be calculated as follows:
P in formulay----periphery hydraulic friction wasted power, kW；
Kf----friction factor coefficient；
Km----coefficient of frictional resistance, it is related with the density of friction media, viscosity and pressure；
----angular velocity of rotation, rad/s；
R---- rotor radius, m；
L---- rotor axial length, m.
Rotor end-face hydraulic friction power loss is calculated by following formula:
P in formulac----end face hydraulic friction wasted power, kW；
Kf----friction factor coefficient；
Cf----coefficient of friction, it is related with the density of friction media, viscosity and the relative dimensions of end face.
From above formula as can be seen that the loss of this partial frictional is bigger, pump efficiency is greatly reduced, from energy-saving
From the perspective of, the type water pump does not meet the requirement of national energy-saving policy.
