Embodiment
The present embodiment Thermal Synthetic mode of propagation controls the comprehensive heat radiation high temperature Under Water Pumps basic structure of heat dispersion as shown in Figure 1, install the pump housing 17 with pump cover 16 and drain pipe 19 below by connecting tube 15 for installing fixing base plate 14, this pump housing 17 is built with impeller 18.The middle frame 10, bearing housing 4, the motor rack 2 that support tubulose above from bottom to top of base plate 14, the bottom of middle frame 10 and bearing housing 4 is respectively equipped with ring-type water-cooling jacket 11,5, therefore effectively can suppress heat transmission upward.Motor rack 2 fixedly mounts motor 1, the output shaft of this motor 1 is in transmission connection with the upper end of pump shaft 9 by the coupling 3 being positioned at motor rack 2.The upper support of pump shaft 9 has in the coaxial upper and lower bearing 6 of sealing configuration at bearing housing two ends.Ring-type water-cooling jacket 5 half section of bearing housing 4 bottom is the inverted "L" shaped of top near pump shaft 9, lower containment lower bearing 6, the lower end buckle closure of bearing housing 4 installs the end cap 7 of lower bearing 6, the lower end of this end cap is provided with ring-type water-cooling jacket 8, thus the encirclement structure formed lower bearing 6 upper end, lower end and part cylindrical, effectively prevent below heat on the impact of bearing.When structure space is comparatively abundant, ring-type water-cooling jacket 5 half section of bearing housing 4 bottom is preferably the inverted "L" shaped of top near pump shaft 9, lower containment lower bearing 6 and end cap lower end ring-type water-cooling jacket 8, thus the encirclement structure formed lower bearing 6 upper end, all cylindrical and lower end, can more effectively stop below heat on the impact of bearing like this.
The bottom of pump shaft 9 is connected through the impeller 18 after middle frame 10 and connecting tube 15 and in the pump housing 17, thus forms pump transmission mechanism.
The axial flow type heat radiation blade 12 being positioned at middle frame 10 pump shaft 9 between the water-cooling jacket of middle frame 10 and bearing housing 4 is equipped with, this radiator shutter 12 circumference is distributed on the blade wheel hub 13 of next-door neighbour's end cap lower end ring-type water-cooling jacket 8, and radiator shutter body and wheel hub are metal fusion welding that thermal conductivity is identical or close or are cast as one.The sidewall of middle frame 10 has vented perforation, and form the open linking body structure of many columns, each column is provided with planar fins.
In order to not only there is desirable heat sinking function, but also effective axial flow being formed, and consider that manufacturing process is simple, the axial flow type heat radiation blade 12 of the present embodiment is through optimal design, concrete structure is as shown in Fig. 2 to 9, the expansion shape of this blade 12 is inner small and outside big isosceles trapezoid, its inner edge and the initial angle of yaw of pump shaft 9 in 61 ° (55 ° of-65 ° of scopes), this angle of yaw strengthens gradually afterwards, until 63.9 of outside ° (60 °-68 °).
The present embodiment controls the high temperature Under Water Pumps of heat dispersion with Thermal Synthetic mode of propagation, utilize and in air, carry out heat loss through radiation by being conducted the heat of coming by pump shaft with the radiator shutter of axle affixed (or melting welding is integrated), because radiator shutter is designed to the aerodynamic characteristics meeting axial blade simultaneously, its hydrodynamics characteristic makes the radiation heat from blade in cross-ventilation, realize directed olderly flowage, therefore test proof and there is following beneficial effect: 1) can by conducted a large amount of high temperature media of coming by pump shaft heat by blade to carrying out heat loss through radiation in the air, to block the conduction of large calorimetric to bearing end, 2) owing to making heat realize oriented and ordered flowing in the process of convection current, thus the heat that the radiation of pump shaft blade position discharges can be flowed towards the direction of high temperature media, with the loss that the heat reducing high temperature media is too much in the process of equipment cooling under the effect of blade.3) under the effect of axial blade, the fresh air of the acquisition normal temperature that pump shaft needs the portion faces of cooling to be able to continuously, effectively can balance pump shaft body and conduct the temperature of coming.
