Abstract
The utility model provides a novel high temperature submerged pump, which comprises a pump body, a shaft and a bottom plate, wherein the bottom plate is provided with a bearing frame, the bearing frame is provided with a lower bearing seat, the lower end of one side of the bearing frame is provided with a cooling water inlet and a strong cold wind inlet, the lower end of the other side is provided with a cooling water outlet and a strong cold wind outlet, the cooling water inlet and the cooling water outlet are communicated with the lower bearing seat, the strong cold wind inlet and the strong cold wind outlet are communicated with the lower portion of the lower bearing seat, the shaft between the lower bearing seat and the bottom plate is provided with a wind cooling radiator, and the lower bearing seat and the bearing frame are fixedly connected. The novel high temperature submerged pump is provided with a cooling water exit between the bearing frame and the lower bearing seat, which leads the bearing frame and a bearing outer ring to be fully cooled, the lower portion of the bearing frame is added with a strong wind supply exit and a strong wind cooling radiator device, the heated degree of a lower bearing inner ring is reduced through the action of external supply cold wind, thereby leading the thermal expansion coefficient of the inner and the outer ring to approach, and greatly increasing the service life of the lower bearing.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of new type high temperature Under Water Pumps.
Background technique
High temperature Under Water Pumps commonly used now is provided with cooling water outlet and inlet at the step place, the cooling water that feeds just cools off the outer shroud of bearing, and bearing bracket stand is not fully cooled off, high temperature makes bearing bracket stand produce distortion like this, thereby influenced the concentricity of metal (upper, bearing inner ring is because the transmission of heat of axle also produces expansion, and this is subjected to inside and outside ring pressure to cause the damage of bearing too greatly with regard to having caused bearing roller.
Summary of the invention
The utility model provides a kind of new type high temperature Under Water Pumps, has solved the high temperature Under Water Pumps Yin Gaowen in the background technique and has caused bearing deformation, the flimsy shortcoming of bearing.
The technical solution of the utility model is achieved in that a kind of new type high temperature Under Water Pumps, comprise the pump housing, axle and base plate, base plate is provided with bearing bracket stand, set bearing support on the bearing bracket stand, bearing bracket stand one side lower end is provided with cooling water intake and strong cold wind import, the opposite side lower end is provided with coolant outlet and strong cold wind outlet, and cooling water intake and coolant outlet communicate with step, and strong cold wind import and strong cold wind outlet communicate with the step below;
Axle between step and the base plate is provided with air-cooled radiator;
Step is fixedlyed connected with bearing bracket stand.
The beneficial effects of the utility model are: high temperature Under Water Pumps of the present utility model is provided with cooling water outlet and inlet between bearing bracket stand and step, bearing bracket stand and outer race are all fully cooled off, the bearing bracket stand below has increased strong air-supply import and export and high wind cold heat sink device, by outer cooling wind action, make ring heating degree reduction in the lower bearing, make the inside and outside ring thermal expansion coefficient approaching, the working life of having improved lower bearing greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Part explanation: 1, strong cold wind import, 2, strong cold wind outlet, 3, step, 4, bearing bracket stand, 5, axle, 6, coolant outlet, 7, cooling water intake, 8, the pump housing, 9, base plate, 10, air-cooled radiator.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of new type high temperature Under Water Pumps, comprise the pump housing 8, axle 5 and base plate 9, base plate 9 is provided with bearing bracket stand 4, set bearing support 3 on the bearing bracket stand 4, bearing bracket stand 4 one side lower ends are provided with cooling water intake 7 and strong cold wind import 1, the opposite side lower end is provided with coolant outlet 6 and strong cold wind outlet 2, cooling water intake 7 and coolant outlet 6 communicate with step 3, strong cold wind import 1 and strong cold wind outlet 2 communicate with step 3 belows, axle 5 between step 3 and the base plate 9 is provided with air-cooled radiator 10, and step 3 is fixedly connected by welding with bearing bracket stand 4.
When pump work, feed strong cold wind by strong cold wind import 1, the strong cold wind that feeds is by the effect of air-cooled radiator 10, taken away the heat of pump shaft, make ring heating degree reduction in the lower bearing, the hot blast that produces is discharged by strong cold wind outlet 2, cooling water is fed by the cooling water intake 7 at bearing bracket stand 4 places, make bearing bracket stand 4 and step 3 obtain cooling, thereby outer race has also obtained cooling, cooling water after the heating is discharged by coolant outlet 6 places of bearing bracket stand 4, goes round and begins again to form circulation, thereby has solved Yin Gaowen effectively and influence the bearing problem in working life.
