Abstract
The utility model relates to a pump submersible in concentrated sulfuric acid at high temperature, comprising such components as a pump body, impellers, a pump shaft, etc. The utility model is characterized in that a position of the cantilevered end of a pump shaft of the pump which corresponds to the pump body is provided with a shaft sleeve and a liner, which forms a sliding seal mechanism. The pump shaft is sheathed with a layer of a fluorine plastic tube. The lower end of a pump cover is provided with an inlet pipe guard and an inlet baffle plate. In order to keep the sulfuric acid lubricating effect between the shaft sleeve and the liner, a communicating tube is arranged between a shaft protecting tube of the pump and the outlet tube. The utility model has the advantages of good sealability, high work efficiency, etc.
Description
The utility model relates to a kind of high-temperature concentrated sulfuric acid Under Water Pumps.
In the existing background technique, opposite position between the pump housing of common Under Water Pumps and the impeller is respectively fitted with pump housing choma and impeller port ring, as the easily damaged parts protection pump housing and impeller, avoids the directly radially contact wear of the pump housing and impeller.Above-mentioned choma is installed simultaneously, can be reduced gap between the pump housing and the impeller, the vent flow when helping to reduce Under Water Pumps work, the working efficiency of raising Under Water Pumps.But for the cantilever Under Water Pumps, because its cantilevered axle lower end does not have any support, pump shaft is subjected to very big radial effect power during work, if design distance is too little between pump housing choma and the impeller port ring, although vent flow can be reduced to minimum degree, cause pump housing strenuous vibration easily, produce very very noisy, because of pump housing choma and impeller port ring wore and tore in the short time, influence cantilever Under Water Pumps working life; If spacing between the above-mentioned choma is strengthened, to the working life that prolongs pump certain effect being arranged, but can cause the fluid vent flow to increase, directly reduced the working efficiency of pump.Therefore for existing cantilever Under Water Pumps design, can only under the working life of assurance pump prerequisite, keep it to have certain fluid vent flow.
For reducing cantilever Under Water Pumps fluid vent flow, improve pump work efficient, the ZL94208351.2 utility model patent has been introduced pump seal axle sleeve under a kind of cantilever liquid, and this axle sleeve does not belong to mechanical seal structure, but utilizes this axle sleeve can reduce gap between the pump shaft and the pump housing.Its shortcoming is that above-mentioned axle sleeve directly contacts wearing and tearing easily with pump housing inwall owing in the pump housing lining is not set.
The purpose of this utility model is to provide a kind of high-temperature concentrated sulfuric acid Under Water Pumps, and this pump is being equipped with axle sleeve and lining near pump shaft cantilever end and pump housing corresponding position.
The utility model above-mentioned purpose is finished like this.
A kind of high-temperature concentrated sulfuric acid Under Water Pumps comprises that the pump housing, impeller, pump shaft and spring bearing thereof and associate member form, and it is characterized in that the corresponding position with the pump housing of said pump shaft cantilever end is equipped with axle sleeve and lining is formed slip lubrication and seal mechanism.Above-mentioned sealing mechanism is lubricated is to rely on impeller back side back blades to drive sulfate liquid to rise, and enters to realize between axle sleeve and the lining.Also can the intermediate connection pipe be set in addition, the sulphur body be entered by the intermediate connection pipe protect in the central siphon lubricative axle sleeve and lining protecting between central siphon and the delivery side of pump pipe of pump shaft.
For preventing the pump shaft corrosion, above-mentioned pump shaft surface can coat one deck fluorine plastic tube.Inlet duct guard and inlet baffle are equipped with in the pump housing end cap lower end of this pump.
The utility model has been owing to assembled axle sleeve and seal with buss mechanism between the pump shaft and the pump housing, and can utilize the above-mentioned sealing mechanism of sulfuric acid liquid self oiling, reduces the pump vent flow, raising Under Water Pumps working efficiency.Simultaneously, can suitably dwindle pump shaft length, increase the pump shaft working stability, prolong axle sleeve and lining working life at pump housing end cap ingress inlet porting pipe network cover and inlet baffle thereof.
Introduce specific embodiment of the utility model below in conjunction with accompanying drawing.
