The driving device includes shell, stator, permanent magnetic rotor and driving shaft assembly. Inside the gap between the stator and the permanent magnetic rotor, there is sealing non-metal jacket to separate the stator and the permanent magnetic rotor, and the gap is maintained inside the effective range of the inducing magnetic field the stator and the permanent magnetic rotor form. The bearing assembly has magnetically suspended bearings. The present invention has simple structure, small size, long operation period, high efficiency, low cost and wide application fields.
Description
Technical field
The present invention relates to liquid and carry the motor-driven pump of use in the industry, especially leak free Magnetic pump.
Background technique
Magnetic force driving pump has become normally used in the industry a kind of new type power pump at present, and it is realized by magnetic coupling, and its good airproof performance is corrosion-resistant, low noise.Typical magnetic drive pump comprises pump assembly, magnetic transmitting assemblies, bearing chamber, shaft joint and motor, as shown in Figure 1, the magnetic transmitting assemblies mainly comprises the external magnetic carrier 104 that is sleeved on seal container shell 102 outsides, the inner magnet carrier 103 that is installed in seal container shell 102 the insides, transmission shaft 110 and bearing 108 and 109, and bearing 108 and 109 is installed in respectively in the inner chamber with the joint of pump assembly and inner magnet carrier 103.By bearing chamber 105 and shaft joint 106, the axle 111 that connects external magnetic carrier 104 and motor 107 rotates under the direct drive of motor, thereby driving external magnetic carrier 104 rotates, inner magnet carrier 103 magnetic couplings are rotated, then drive the transmission shaft 110 that is connected with it and rotate, thus impeller 101 rotations.Yet, this pump structure complexity, volume is big, and parts are many, and only bearing just has 8 (interior 4 of seal container shell, interior 2 of bearing chamber, interior 2 of motors).And owing to adopt electromagnetic suspension bearing, cost an arm and a leg, its application area is restricted.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, volume is little, the Magnetic pump that can prolong service cycle, and efficient height, cost is low, overcomes the technological deficiency that exists in the above-mentioned prior art.
To achieve these goals, the invention provides a kind of Magnetic pump, this Magnetic pump comprises pump assembly and drive unit, described drive unit comprises housing, stator, p-m rotor and drive shaft assembly, be provided with nonmetal stuffing box gland in the gap between stator and p-m rotor, stator and p-m rotor are kept apart, and described gap remains in the induction field effective span scope of stator and p-m rotor formation.
The outer side of described nonmetal stuffing box gland is close on the inner side edge of described stator, so that the pressure that carrying internal work liquid produces.
In drive unit, set up nonmetal stuffing box gland, stator coil and p-m rotor are kept apart, make live axle in the drive unit can directly connect the impeller shaft of pump assembly, not only simplify the structure, also can prolong the equipment operation cycle, increase work efficiency.
Description of drawings
From below in conjunction with the accompanying drawing detailed description of the present invention, will understand purpose of the present invention and These characteristics and other characteristics preferably.
Fig. 1 is the structural representation of magnetic drive pump in the prior art;
Fig. 2 is the structural representation of Magnetic pump of the present invention.
Embodiment
Fig. 2 shows the general structure of Magnetic pump of the present invention, and this Magnetic pump comprises pump assembly and drive unit, and the pump housing 1 of pump assembly is connected with the housing of drive unit 9 usefulness bolts, realizes that the outside of the two connects.In drive unit, stator coil 3 is fixed on the housing 9, and p-m rotor 4 is fixedlyed connected with live axle 10 by axle sleeve 12, and permanent magnet 6 is embedded in the outer side of rotor 4.Have additional the barrel-shaped nonmetal stuffing box gland 7 of band outer in the gap between stator 3 and p-m rotor 4, the outer part is connected with the pump housing 1 static seal, thereby makes parts such as the p-m rotor, drive shaft assembly of nonmetal stuffing box gland 7 inside and outside stator, housing keep apart mutually.The outer side of nonmetal stuffing box gland 7 is close on the inner side edge of stator 3, makes it can carry the pressure that internal work liquid produces.Drive shaft assembly comprises live axle 10, be installed in the magnetic suspension bearing on the live axle and be fixed in propeller shaft sleeve 12 on the live axle.One end of live axle 10 is inserted in magnetic suspension bearing 8, its termination is not connected with any parts, and the other end is fixedlyed connected with the transmission shaft 11 of impeller 2, like this, connect with the pump housing 1 static seal with nonmetal stuffing box gland 7, finished the pump assembly and be connected with the inside of drive unit.
Gap between stator 3 and the p-m rotor 4 can not exceed induction field effective range therebetween, otherwise will influence the drive unit working efficiency.Work for drive unit can be stablized effectively, installation supervisory device 5 on stator 3 to monitor the variation in this gap, is in time adjusted, and realizes monitoring automatically, makes in its induction field effective span scope that remains on stator 3 and p-m rotor 4 formation.
Nonmetal stuffing box gland 7 can adopt corrosion resistant industrial plastic to manufacture, and also can adopt carbon fibre material to manufacture.The capsul of magnetic transmitting assemblies uses metallic material to manufacture in the prior art, produces eddy current, and the present invention then eddy current can not occur, helps to raise the efficiency.
The working principle of Magnetic pump of the present invention: connect the power supply (not shown) and make stator 3 work, the p-m rotor 4 that drives in the nonmetal stuffing box gland 7 rotates, thereby make the propeller shaft sleeve 12 and live axle 10 rotations that are connected with it, then drive transmission shaft 11 rotations that the outside is with the impeller 2 of magnetic suspension bearing 8, thereby impeller 2 is rotated.Magnetic pump of the present invention is dexterously by set up nonmetal stuffing box gland in the stator of motor and gap between rotor existing magneto and magnetic transmitting assemblies, realized five parts of original magnetic drive pump are simplified to two parts of the present invention, not only simplify the structure greatly, dwindled volume, and avoided the puzzlement of eddy current, live axle directly affacts on the transmission shaft of impeller, what bearing was selected for use in addition is magnetic suspension bearing, thereby prolonged the operation period of Magnetic pump, reduce cost, improved reliability and efficient significantly.
