Abstract
The utility model discloses a minitype water pump, which comprises a brushless motor, pump connection fixing rack, a guide sleeve, a waterproof ring, a water pump impeller and a pump head. The pump is characterized in that the rotor of the brushless motor is provided with a long output shaft; the middle of the water pump connection fixing rack is made in hollow structure; the guide sleeve and the waterproof ring are installed inside the structure, of which the two ends are provided with a flange; the flange at one end is connected with the brushless motor; the other end is connected with the pump head; the output end of the brushless motor is connected with the water pump impeller installed inside the pump head by penetrating through the guide sleeve and the center of the waterproof ring; the pump head is provided with a water inlet and outlet; the water pump is incorporated with separation of the motor and the impeller; the waterproof ring structure is adopted in the middle. The water pump can not be damaged even if the liquid contains iron impurity so as to extend the working life.
Description
Technical field
The utility model belongs to the pump technology field, is specially a kind of micro pump.
Background technique
Existing micro pump, rotor all are directly to be connected with water pump vane, and circuit liquid requires to be forbidden to contain impurity, if contain impurity in the liquid, especially the impurity of irony is adsorbed on the p-m rotor of motor easily, cause water pump to damage, shorten working life.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of micro pump is provided, and this water pump vane separates with motor, can circulate and contain the liquid of impurity, long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of micro pump, comprises brushless electric machine, water pump Connection Bracket, guide sleeve, waterproof ring, water pump vane and pump head; Be characterized in having a long output shaft on the rotor of brushless electric machine, this brushless electric machine and water pump Connection Bracket link together by bolt; In the middle of the water pump Connection Bracket is hollow-core construction, and the inside is installed with guide sleeve and waterproof ring, and two ends have flange plate; The center that the output shaft of brushless electric machine passes guide sleeve and waterproof ring is connected with water pump vane, and water pump vane is installed in the pump head the inside, has water inlet B and water outlet C on the pump head, and pump head is connected with the water pump Connection Bracket by bolt.
Owing to adopted such scheme, motor separates with water pump vane, and there is waterproof ring the centre, and liquid just can not contact with rotor yet, also can not cause water pump to damage even contain irony impurity in the liquid, has obtained prolongation working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's a structure sectional view;
Fig. 2 is the utility model embodiment's a plan view
Embodiment
As shown in Figure 1, a kind of micro pump comprises brushless electric machine 1, water pump Connection Bracket 2, and guide sleeve 3, waterproof ring 4, water pump vane 5 and pump head 6 have a long output shaft on the rotor of brushless electric machine 1; In the middle of the water pump Connection Bracket 2 is hollow-core construction, and the inside is installed with guide sleeve 3 and waterproof ring 4, and two ends have flange plate, and an end flange dish is connected with brushless electric machine 1, and the other end flange plate is connected with pump head 6; The center that the output shaft of brushless electric machine 1 passes guide sleeve 3 and waterproof ring 4 is connected with water pump vane 5, water pump vane 5 is installed in pump head 6 the insides, have water inlet B and water outlet C on the pump head, this water pump has adopted motor to separate with water pump vane, the middle structure that adopts waterproof ring, also can not cause water pump to damage even contain irony impurity in the liquid, prolonged much working life.
