Description
Technical field
The invention belongs to submersible pump technical field, and in particular to a kind of outer rotor submersed three-flow pump.
Background technology
Submersed three-flow pump has two kinds of structural shapes, and a kind of is the submersed three-flow pump of traditional dry-type submersible motor adapted, one
It is impeller built-in submersed three-flow pump to plant.
In the submersed three-flow pump of traditional dry-type submersible motor adapted dry-type submersible motor and the pump housing be it is relatively independent, most
Distinguishing feature is that the structure of submersible pump is that dry-type submersible motor is coaxially connected with immersible pump, and dry-type submersible motor is placed in diving electricity
In the outlet passage of pump, the impeller of pump enters waterside in unit.The impeller of pump pumps current, and water outlet is flowed to by the outer wall of motor
In runner.Adapted dry-type submersible motor is all-sealed structure, and inner chamber is dry air.The submersible pump of this structural shape is present
Following weak point：First, submersible motor is submerged in water for a long time, the sealing of motor it is difficult to ensure that, particularly in submergence
When in deeper water, the electric insulation of motor can not obtain Reliable guarantee, and dry-type submersible motor has potential safety hazard；Secondly, pump
Impeller be cantilever beam structure, i.e., only have a bearing pivot in the side of impeller.This structural requirement machining accuracy is high, while
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, can influence to pump the water outlet fluidised form of current, directly affect the effect of submersible pump
Rate.Former submersible pump complex structure, axial length is more long, not easy-maintaining, open and inspect.
Impeller built-in submersed three-flow pump most distinguishing feature is that the impeller assembly of submersible pump is fixed on into Water diving
Rotor inner chamber, formula rotor is integrally formed with Water-filled Type Submersible Motors rotor welding, and integral type rotor is dived under water positioned at Water
Inside motor stator, Water-filled Type Submersible Motors stator is fixedly installed in stator casing, and the axial two ends of stator casing connect respectively
Suction chamber and water-supplying chamber are met, simple structure, a compact impeller built-in submersed three-flow pump is so formed.
The impeller built-in submersible pump Shortcomings part of the structural shape：Because its integral type rotor (impeller assembly with
Water-filled Type Submersible Motors rotor) rotated in water, impeller assembly is rotating the frictional dissipation of generation with common water pump just in water
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 up of two parts：One is the friction loss of Water-filled Type Submersible Motors rotor cylinder surface, its 4 time with rotor radius
The length of side and rotor is directly proportional；Two is the friction loss of rotor end-face, and 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 face of cylinder 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, the density, viscosity and pressure with friction media is relevant；
----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, the relative dimensions of density, viscosity and end face with friction media are relevant.
From above formula as can be seen that this partial frictional loss ratio is larger, pump efficiency is greatly reduced, from energy-saving
Angle for, the type water pump does not meet the requirement of national energy-saving policy.
