Abstract
A double-ended shield pump consists of a first pump body, a second pump body and a shielded electric machine, wherein the first pump body is provided inside with a first impeller; the second pump body is provided inside with a second impeller; both ends of the rotor shaft of the shielded electric machine are respectively connected with the first impeller and the second impeller; the inlet direction of the second impeller is opposite to that of the second impeller; the first pump body is provided inside with a first inlet and a first outlet; the second pump body is provided inside with a second inlet and a second outlet; and the periphery of the shielded electric machine is provided with a cooling jacket. The double-ended shield pump sets the shaft tail of one water pump as the shaft head of another water pump, and makes comprehensive use of the parts inside the pumps, thereby realizing function combination within permissible load and reducing manufacturing cost; meanwhile, the shield pump reduces axial unbalance force and volumetric losses and increases unit efficiency; moreover, the shield pump reduces installation cost and increases land utilization rate.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pump, particularly a kind of double end canned motorpump.
Background technique:
In the prior art, conventional pump, canned motorpump all are the hydraulic machinerys that the unit head by an end drives the other end, and there is axial unbalanced force in the suffered Maximum Torque of pump shaft between impeller and rotor, cause volumetric loss, and unit efficiency is low.
Summary of the invention:
The purpose of this utility model provides a kind of double end canned motorpump, and described this double end canned motorpump will solve the inefficient technical problem that exists in the shield electric machine single head driving water pump structure in the prior art.
This double end canned motorpump of the present utility model is made of one first pump housing, second pump housing and a shield electric machine, be provided with one first impeller in described first pump housing, be provided with one second impeller in described second pump housing, it is characterized in that: the two ends of the rotor shaft of described shield electric machine are connected with second impeller with described first impeller respectively, the importer of first impeller to the importer of second impeller to opposing, be provided with first inlet and first outlet in described first pump housing, be provided with second inlet and second outlet in described second pump housing.
Further, the periphery at described shield electric machine is provided with cooling jacket.
Working principle of the present utility model is: usually the suffered Maximum Torque of pump shaft is between impeller and rotor, the axle tail is stressed little, therefore in the utility model the axle tail of a water pump is arranged to the spindle nose of another water pump, thereby drive another impeller, determine the different loads of two pump according to the force analysis of axle, one of them water pump can be finished the cooling of the lubricated and motor of bearing, the relevant work energy of another pump just can save, reduce the quantity or the area of impeller balance hole simultaneously, reduced volumetric loss, also improved unit efficiency, efficient is than two independent pump height;
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged to the spindle nose of another water pump with the axle tail of a water pump, and the component in the comprehensive utilization pump accomplish that when load allows function is synthetic shared, reduce manufacture cost; Reduce axial unbalanced force, reduce volumetric loss, improve unit efficiency; Reduce installation cost, improve land use capability.
Description of drawings:
Fig. 1 is the structural representation of double end canned motorpump of the present utility model.
Embodiment:
As shown in Figure 1, double end canned motorpump of the present utility model is made of shield electric machine 1, first pump housing and second pump housing, be provided with one first impeller 5 in described first pump housing, be provided with one second impeller 6 in described second pump housing, the two ends of the rotor shaft 4 of described shield electric machine are connected with second impeller 6 with described first impeller 5 respectively, the importer of first impeller 5 to the importer of second impeller 6 to opposing, be provided with 51 and first outlet 52 of first inlet in described first pump housing, be provided with 61 and second outlet 62 of second inlet in described second pump housing.
Further, the periphery of described shield electric machine 1 is provided with cooling jacket (not drawing among the figure).
Further, the rotor periphery of described shield electric machine 1 is provided with the bearing 7 at liquid cooling radiator cooler 3, the first impellers 5 and described second impeller 6 close shielding motor rotor axle 4 two ends.
