Abstract
The utility model discloses a novel pump, which comprises a direct current motor stator (1), a rotor (2) and a gear pump (3), wherein the rotor (2) is connected with the gear pump (3) through a shaft; a seal cover connected with the gear pump is arranged outside the rotor; the rotor (2) is arranged at the center of a stator coil of the direct current motor stator; an isolation cover (5) isolated from the stator coil of the direct current motor stator is arranged outside the rotor; the direct current motor stator (1) is fixedly connected with the gear pump (3). The novel pump is simple and compact in structure, and wide in application range.
Description
Technical field
The utility model relates to a kind of new pump.
Background technique
Existing pump mainly is comprised of motor, outer magnetic ring, internal magnetic ring, rotor and gear pump, external outer magnetic ring on motor shaft, outer magnetic ring fit internal magnetic ring, internal magnetic ring is connected with rotor, rotor is connected by axle with gear pump, and outer magnetic ring rotates under the driving of motor shaft, due to magnetic action, internal magnetic ring rotates along with the rotation of outer magnetic ring, thereby rotor driven rotates.Existing pump structure complexity, its spendable scope is subject to great restriction.
The model utility content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of simple in structure, compact, the new pump had wide range of applications.
The utility model adopts following technological scheme: a kind of new pump, comprise DC motor stator (1), rotor (2) and gear pump (3), rotor (2) is connected by axle with gear pump (3), rotor exterior is provided with the sealing cover be connected with gear pump, rotor (2) is located at the central position of the stator coil (1) of DC motor stator, and rotor exterior is provided with the isolation lid (5) isolated with the stator coil of DC motor stator, and DC motor stator (1) is fixedly connected with gear pump (3).
Particularly, the DC motor stator of new pump (1) is connected by fixing bolt or screw with gear pump (3).
The utility model is simple in structure, compact, has wide range of applications.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Illustrate mode of execution of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of new pump, comprise DC motor stator 1, rotor 2 and gear pump 3, rotor 2 is connected by axle with gear pump 3, rotor exterior is provided with the sealing cover be connected with gear pump, rotor 2 is located at the central position of the stator coil 1 of DC motor stator, and rotor exterior is provided with the isolation isolated with the stator coil of DC motor stator lid 5, and DC motor stator 1 is connected (not shown fixing bolt and screw) with gear pump 3 by fixing bolt or screw.Careless leakage when sealing cover can prevent the gear pump running, the isolation lid can prevent that leakage from may leak out on motor stator, affects the usability of stator coil.
Be evenly distributed with three groups of Hall elements 4 along peritrochanteric in DC motor stator, the control end of Hall element 4 and amplification circuit is connected, and the output terminal of amplification circuit is connected with stator coil.
Illustrate: the gear pump of mentioning due to the utility model is common structure pump, therefore do not draw its detailed concrete structure in Fig. 1.
Compare with the pump of driving gear pump running by the interaction between interior outer magnetic ring with existing, the utlity model has simple in structure, compact advantage, can design various power pump heads, can be widely used in various occasions.
Claims (2)
1. a new pump, comprise DC motor stator (1), rotor (2) and gear pump (3), it is characterized in that, rotor (2) is connected by axle with gear pump (3), rotor exterior is provided with the sealing cover be connected with gear pump, rotor (2) is located at the central position of the stator coil (1) of DC motor stator, and rotor exterior is provided with the isolation lid (5) isolated with the stator coil of DC motor stator, and DC motor stator (1) is fixedly connected with gear pump (3).
2. new pump according to claim 1, is characterized in that, described DC motor stator (1) is connected by fixing bolt or screw with gear pump (3).
