Abstract
The utility model provides a novel molten salt under liquid pump, which comprises a pump body and vane wheels contained in the pump body, the vane wheels are fixed and equipped on an end of the pump shaft driven by the generator, a support pipe, a water tank seat and a bearing seat are fixed and equipped on the pump body in turn, the pump shaft is drilled through and equipped on the bearing equipped respectively on the water tank seat and the bearing seat, the utility model is characterized in that a wind wheel is sleeved on the pump shaft of the cave positioned on the water tank, an air vent is provided on the cave wall. The ring shape cooling water tanks are equipped in the wall of the bearings correspondingly equipped on the water tank seat and the bearing seat respectively, a communicating ring shape cooling water tank with both a water inlet and a water outlet and an external water tank are also provided. A gland fixed on the water tank seat is sleeved on the pump shaft positioned on the edge between the inner part of the water tank seat and the support pipe, the cave of the gland is filled with the high temperature-resistant flexible material produced by the mixture of the carbon fiber and the plumbago. The good effects of the utility model are that the temperature is efficiently reduced by the multiple cooling and the heat insulation measures when running, thereby enhancing the use life of the pump.
Description
Technical field:
The utility model relates to the improvement of Under Water Pumps, relates in particular to a kind of improvement of carrying special high temperature media Under Water Pumpss such as fused salt.
Background technique:
At present, self-priming pump finds broad application in departments such as environmental protection, fire-fighting, agricultural, chemical industry.And the fused salt Under Water Pumps is to be widely used in conveying high temperature, the pump of special media liquid.General Under Water Pumps is equipped with bearing in the bottom, because the temperature of fused salt is higher, generally can reach about 450 degree, bearing is very easily wearing and tearing under so high temperature, cause the gap to increase, thereby cause vibration, be that pump can not run well, have influence on the working life of pump.
Summary of the invention
The utility model provides a kind of novel molten salt Under Water Pumps, and its purpose is to overcome the prior art shortcoming, improves its working life for the fused salt Under Water Pumps provides better cooling-down effect.
For achieving the above object, the utility model is taked following scheme:
A kind of novel molten salt Under Water Pumps, comprise the pump housing and the impeller that is contained in the pump housing, impeller is installed in the end by motor-driven pump shaft, be installed with support column, water tank seat, the bearing support of hollow on the pump housing successively, pump shaft is arranged in the bearing that is provided with separately in water tank seat, the bearing support, it is characterized in that: be positioned on the pump shaft of water tank seat inner chamber and be arranged with wind wheel, this internal chamber wall is provided with ventilated port.
Above-mentioned wind wheel can make the air of water tank seat inner chamber and ambient air generation exchange play cooling action by rotation.
Be equipped with the annular cooling water case in the corresponding bearings mounted wall of water tank seat and bearing support, all have water intake and water outlet again and be communicated with annular cooling water tank and external water tank.
Above-mentioned annular cooling water case can make cooling water that bearing is cooled off.
Be arranged with the lining of silicon nitride ceramic material material on the pump shaft of impeller rear end.
The lining of above-mentioned silicon nitride ceramic material material is high temperature resistant, and is wear-resisting, docks the supporting effect that subterminal pump shaft plays similar bearing, and avoids using plain bearing.
Be positioned on the pump shaft of water tank seat and support column intersection and be arranged with the gland that is fixed on the water tank seat, the gland inner chamber is filled the high-temperature flexible material that is mixed and made into by carbon fiber and graphite.
The above-mentioned high-temperature flexible material that is mixed and made into by carbon fiber and graphite.Wear-resisting, high temperature resistant, heat insulation, and owing to its flexible effect of playing further sealing.
The usefulness of technique scheme is: the temperature when multiple cooling and heat insulation measures have effectively reduced the bearing operation, thereby the working life of having improved pump.
