Abstract
The utility model relates to a shielding type vortex pump with low flow rate, high lift and high efficiency, which comprises a pump body, an impeller, a stator assembly, a rotor assembly, a front bearing seat and a back bearing seat, wherein the rotor assembly comprises a rotor shaft. The utility model has the improvement that the impeller is a 72-tooth closed impeller, the front bearing seat is in a flange shape, liquid passing holes are arranged at one side of the outer periphery of the front bearing seat, the rotor shaft of the rotor assembly is provided with axial holes along the axial lead, and a liquid passing groove is arranged at an inlet of the pump body. The shielding type vortex pump integrates the advantages of the shielding pump and the vortex pump into one body, has the advantages of no leakage, low noise and small size and realizes high lift, high efficiency and low cost under the work condition of low flow rate. The efficiency of the shielding type vortex pump with the same parameters is 8 percent to 10 percent higher than that of the conventional pump, and the energy saving effect is obvious.
Description
Technical field
The utility model belongs to the pump technical field, is specifically related to the high efficiency shielding peripheral pump of a kind of low-flow high-lift.
Background technique
The use occasion less for flow, that lift is higher, conventional canned motorpump usually adopt unshrouded impeller, and unshrouded impeller efficient is lower owing to limited by minimum discharge, and impeller outer diameter is bigger, thereby the volume of pump is also bigger.Conventional peripheral pump relatively adapts to the operating mode of low-flow high-lift, but has the possibility of leaking.
Summary of the invention
Have the problem of leaking in order to solve bigger, the conventional peripheral pump of conventional canned motorpump volume, the utility model provides a kind of lift height, efficient height, the high efficiency shielding peripheral pump of little, the complete leak free low-flow high-lift of volume.
Concrete technical solution is as follows:
High efficiency this pump of shielding peripheral pump of a kind of low-flow high-lift comprises the pump housing, impeller, stator module, rotor assembly, front-end bearing pedestal and rear bearing block, and rotor assembly comprises rotor shaft;
Described impeller is 72 tooth double shrouded wheels;
Described front-end bearing pedestal is the flange plate-like, and its, side was provided with liquid pass hole outer Monday
The rotor shaft of described rotor assembly is provided with axle center hole along shaft axis;
The inlet of the described pump housing offered liquid bath.
The utility model integrates canned motorpump and the two advantage of peripheral pump, has the little advantage of no leakage, low noise and volume, and lift height, efficient height, cost are low under low flow rate condition.The utility model of same parameter is higher by 8%～10% than conventional pumps efficient, and energy-saving effect is remarkable.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, the high efficiency shielding peripheral pump of a kind of low-flow high-lift comprises component compositions such as the pump housing 1, impeller 2, stator module 3, rotor assembly 4, front-end bearing pedestal 5, rear bearing block 6, fore bearing 7, rear bearing 8, axle sleeve 9, thrust disc 10.Stator module 3 inner radius stud with stator can 11, and rotor assembly 4 outer radius stud with Rotor can 12.Impeller 2 is 72 tooth double shrouded wheels; Front-end bearing pedestal 5 is the flange plate-like, and its, side was provided with liquid pass hole 13 outer Monday, saw Fig. 2 and Fig. 3; The rotor shaft of rotor assembly is provided with axle center hole 14 along shaft axis, sees Fig. 4; The inlet of the pump housing offered liquid bath 15, saw Fig. 5.
During work, carry liquid to flow into from the import of the pump housing 1, increasing energy through impeller 2 flows out from the outlet of the pump housing 1, motor cooling and bearing lubrication liquid are introduced from the liquid pass hole 13 on the front-end bearing pedestal 5, come the cavity of rear bearing block 6 by the gap between the gap between stator can 11 and the Rotor can 12, rear bearing 8 and the axle sleeve 9, get back to the cavity of front-end bearing pedestal 5 again from the axle center hole 14 of rotor assembly, get back to pump intake by the liquid bath 15 of crossing on the pump housing at last, play the effect of cooling motor lubricating bearings.
