Abstract
The utility model relates to a direct coupled type electromagnetic driven pump, which is mainly composed of a motor stator, a distance sleeve, a rotor, a pump case, etc. The motor stator replaces outer magnetic steel which is arranged in a magnetic coupling device of the utility model, and the motor stator directly drives the rotor (inner magnetic steel or a squirrel cage) and drives an impeller to work.
Description
The utility model belongs to pump and compressor class.
Widely used electromagnetic pump in industries such as chemical industry, pharmacy, plating, film developing and printing all adopts the magnetic force coupling at present, and pump shaft and motor shaft separate fully, have thoroughly solved sealing and leakage problem.Its structural type is as shown in Figure 1: sequence number 1 is a pump case, and 2 is stationary ring, and 3 is rotating ring, and 4 is impeller, and 5 is seal ring, and 6 is dividing plate, and 7 is separation sleeve, and 8 is the outer steel assembly, and 9 is interior magnet steel assembly, and 10 is pump shaft, and 11 is pump block, and 12 is hitch, and 13 is motor.Owing to need to leave enough rotation spaces between the interior magnet steel 9 of magnetic coupling and the outer steel 8, thereby produce the magnetic gap loss, transmission efficiency is reduced.Like this electromagnetic pump of being made up of common electric machine and magnetic coupling splicing, volume are greatly and install and use inconvenience.
The purpose of this utility model is: design a kind of structure, so that a kind of new electromagnetic coupling mode to be provided, direct electromagnetic force with motor drives the interior magnet steel 9 as rotor, cancellation outer steel 8, eliminate the magnetic gap loss between inside and outside magnet steel, thereby make designs simplification, volume-diminished is increased work efficiency simultaneously.
Technical measures of the present utility model are: remove the outer steel 8 that links to each other with motor, motor stator directly is enclosed within on the separation sleeve 7.Owing to do not relatively rotate, stator can closely be connected with separation sleeve and not stay the gap.Magnet steel 9 rotated in the rotating magnetic field of motor stator directly drove, the coupling between cancellation outer steel 8 and the interior magnet steel 9.
Fig. 2 is a structural representation of the present utility model.Drawing explanation and embodiment are described below:
14 is motor stators among the figure, and other are identical with Fig. 1.Motor stator 14 is made of one with separation sleeve 7, is convenient to install to simplify technology.Because fit back structural strength has improved, it is thinner that separation sleeve 7 can be done, and further reduced the magnetic gap loss.Owing to cancelled outer steel and original motor mouse cage, motor and magnetic coupling are united two into one, thereby make compact structure, cost reduces, and efficient has also improved.In the former electromagnetic pump, exist between motor stator and the cage rotor, totally three place's magnetic gaps between Coupler outer steel and the separation sleeve, between separation sleeve and the interior magnet steel, existing only have a place between motor stator and the interior magnet steel, magnetic gap loss has reduced 2/3rds.
In the present embodiment, be to make rotor, therefore rotate by the synchronous machine mode with interior magnet steel.Interior magnet steel also can change the mouse cage of asynchronous motor into, thereby works by the asynchronous motor mode.Mouse cage can equally with interior magnet steel rotor be done preservative treatment, and isolated fully with the external world.
Claims (3)
