Abstract
The utility model relates to a safe magnetic force booster pump characterized by utilizing a motor rotor to export dynamic. Wherein, one end of a motor rotor extends to an enlarging cup-shaped. The inner side of the cup mouth is press-connected with an outer magnetic assembly. The outer magnetic assembly forms a magnetic coupling with an inner magnetism fastened with an impeller assembly. The rotor is located on a motor shaft through bearings arranged on two sides of the rotor. The motor and the impeller are isolated through a separation sleeve. A motor casing is directly fastened with the pump casing. The utility model has the advantages that a transition with a motor shaft and a magnetic steel cup is not needed in the middle, and economizes a connection holder. Thereby, the utility model economizes the integral space and materials of the pump and has a compact structure and smooth and steady transmission.
Description
It is the pump of feature that the utility model relates to the rotor outputting power, particularly a kind of safe magnetic booster pump.
Existing family pipe pressurizing pump has multiple mode of structure, wherein a kind of is the coupling type pump that motor shaft and impeller fuse, it adopts mechanical dynamic seal, be in operation, As time goes on, because of the wearing and tearing of mechanical seal, cause the water clock of water that user's household is destroyed, even cause electrical short-circuit and cause fire.In order to reduce the water clock that causes because of mechanical dynamic seal said pump is improved, motor shaft and impeller shaft are disconnected, the magnetic booster pump that motor shaft forms by the magnetic shaft coupling transmission, as shown in Figure 2, it fuses the motor and the pump housing by link press span 22, link press span 22 is connected with motor shaft 25 by bearing 23, place the outer steel cup assembly 21 in the link press span 22 to fixedly connected with motor shaft 25, motor, outer steel cup assembly 21 is isolated by separation sleeve 19 with the impeller assembly 18 that is coated with interior magnetic, separation sleeve 19 seals by O-ring seals 20 with pump case 16, outer magnetic and interior magnetic are composed of magnetic shaft coupling, the impeller shaft two ends by bearing 17 respectively with separation sleeve 19, impeller assembly 18 is connected.Compare with first kind of pump, advantage is to have made mechanical dynamic seal into static seal, has eliminated water clock, and deficiency one is that the overall space of pump takies greatly, and is big with the material amount; The 2nd, motor shaft is longer, and motor shaft one end connects support, behind the outer steel cup assembly, and the relatively poor easy generation vibration of balance.
The purpose of this utility model provides a kind of compact structure, the stable transmission safe magnetic booster pump.
In order to achieve the above object, safe magnetic booster pump of the present utility model, comprise motor, pump case, by impeller, impeller shaft, interior magnetic, interior magnetic coating member fuse the impeller assembly formed, separation sleeve, be composed of outer magnetic assembly, the bearing of magnetic shaft coupling with interior magnetic; Rotor one end extension in the described motor becomes the enlarging cup-shaped, inboard being press-fitted with described outer magnetic assembly of rim of a cup is connected, rotor is positioned on the motor shaft by the bearing that is arranged on its two ends, the two ends of motor shaft are bearing in respectively on electric machine casing, the separation sleeve, accompany seal ring between the uncovered edge of separation sleeve and the front-end bearing pedestal edge on the impeller assembly, the three is fastened between electric machine casing, the pump case with fixedlying connected of pump case by electric machine casing.
The utility model by rotor one end extension, directly press fit in the extension port outer magnetic assembly owing to adopted said structure, the centre need not motor shaft and the transition of magnet steel cup, save link press span, thereby saved the overall space and the material of pump, made overall structure very compact; Directly drive the magnetic shaft coupling transmission that outer magnetic, interior magnetic are formed by rotor, make transmission more steady, eliminated, the vibration that causes by the motor shaft transmission because motor shaft is long.
Below in conjunction with drawings and Examples the utility model is described in further detail,
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of prior art magnetic booster pump.
As shown in Figure 1, the safety magnetic suction booster of the present utility model impeller assembly 3, impeller front-end bearing pedestal 4, impeller bearing, seal ring 5, outer magnetic assembly 6, separation sleeve 8, electric machine casing 9, preceding conduit bushing 10, motor stator 11, rotor 12, motor shaft 13, spring 14, the bearing 15 that comprise pump case 1, impeller baffle ring 2, fuse and form by impeller, impeller shaft, interior magnetic 7, interior magnetic coating member.One end extension of rotor 12 becomes the enlarging cup-shaped, inboard being press-fitted with outer magnetic assembly 6 of rim of a cup is connected, rotor 12 is positioned on the motor shaft 13 by the bearing 15 that is arranged on its two ends, one end of motor shaft 13 also be with transfer crack spring 14 and be bearing on the electric machine casing 9, the other end is positioned separation sleeve 8, accompany seal ring 5 between separation sleeve 8 and the impeller front-end bearing pedestal 4, their threes are clipped in the joint of electric machine casing 9 and pump case 1, when electric machine casing 9 and pump case 1 were fastenedly connected by screw, their threes also had been fastened on therebetween.During work, motor shaft 13 does not change, and rotor 12 drives outer magnetic assembly 6 rotations, rotates by the interior magnetic 7 drives impeller assemblies 3 with outer magnetic pairing use.
