Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of water pump, particularly to a kind of high speed well immersible pump.
Background technology
Well immersible pump is motor and the pump housing to be formed integrally, and is to immerse in underground water well to carry out aspirating and carry the one of water
Plant pump, be widely used in farmland discharging-irrigating, industrial and mining establishment, urban water supply and sewerage and sewage disposal etc..Slip into water due to motor simultaneously
In, and owing to the motor speed of high speed well immersible pump is the highest, therefore the structural requirement for motor is more special than general motor, electricity
The structural requirement of arbor is the highest.
Motor shaft and impeller axle in existing well immersible pump are to realize split by the spline coordinated to connect, this
The pump shaft being provided with spline in use has the following disadvantages: on the one hand, owing to pump shaft upper spline beginning is arranged
There is groove, thus in running, positioning groove is easily generated stress concentration, ultimately results in axle fracture；On the other hand, spline knot
Structure is complicated, and processing time consuming is laborious, and Cutter wear is big, and manufacturing cost is high, and axiality is difficult to ensure that.
And current high speed immersible pump is in order to reach the regulatory function of pressure, flow etc., its controller and pump housing split, it is subject to
The restriction of Split type structure, the volume of whole immersible pump cannot be made less, due also to pump and controller cannot be put in some occasion
Together, the circuit between controller and pump is oversize, and frequency-variable controller higher hamonic wave impact, cause converter and pump without
Method normally works, and this phenomenon limits its range.
Summary of the invention
It is an object of the invention to for the above-mentioned problems in the prior art, it is provided that a kind of operating is stable, work effect
The high speed well immersible pump that rate is high
The purpose of the present invention can be realized by following technical proposal: a kind of high speed well immersible pump, including the pump housing, motor and the end
Seat, is provided with pump shaft and the impeller sets being rotated by pump shaft in the described pump housing, the motor shaft of described motor is with pump shaft even
Connect, it is characterised in that be provided with the radiator being close to motor housing between described motor and base, in described radiator
Being provided with the controller that can control motor speed, described motor uses permanent-magnet brushless DC electric machine.
By certain program work set.Such immersible pump has permanent-magnet brushless DC electric machine high-speed cruising ability,
And volume is little, lightweight, simpler, practical, more reliable, pump work rotating speed certain high speed or speed change work by program setting
Make.Both played the various excellent control function of this immersible pump, and reduced the cumulative volume of pump and controller, eliminated converter humorous
The a series of bad problem that wavestrip is come, effectively overcomes the controller restriction to the distance of pump.
In above-mentioned a kind of high speed well immersible pump, the upper and lower end face of described radiator is mounted on protecting cover, described
Radiator internal be full of silica gel.The setting of protecting cover and silica gel makes the controller in radiator more firm, and effect of dispelling the heat
Fruit is more preferably.
In above-mentioned a kind of high speed well immersible pump, the material of described radiator be aluminum material or copper material or
Albronze material.
In above-mentioned a kind of high speed well immersible pump, it is connected by shaft coupling between described motor shaft and pump shaft, institute
The end of the motor shaft stated has the union joint of flat shape in conjunction, and the cross section of described pump shaft is regular hexagon, institute
The one end of the shaft coupling stated offers and coordinates, for union joint, the flat groove snapped in, and the other end offers joins for pump shaft and just stretches into
Hexagonal hole.The adapter of this structure makes its contact area connected bigger, weares and teares and diminish in rotation process, and stability is more
High.
Compared with prior art, this high speed well immersible pump has the advantage that
1, using permanent-magnet brushless DC electric machine, it has, and volume is little, efficiency is high, the advantage of simple in construction, can make this immersible pump
Work efficiency improve, volume-diminished.
2, controller is installed in radiator by silicone filler, it is to avoid controller is designed by tradition with pump housing split
Structure so that its manipulation is convenient.
3, pump shaft is connected by flat shaft coupling with motor shaft, in shaft coupling respectively offered for flat shape union joint with
The flat groove of hexagon pump shaft installation and regular hexagon hole so that its contact area connected is bigger, weares and teares in rotation process
Diminishing, stability is higher.
