Description
Technical field
The utility model relates to a kind of special Under Water Pumps, is specifically related to a kind of major axis superhigh temperature concentrated sulphuric scid Under Water Pumps.
Background technique
Special Under Water Pumps is meant the high temperature Under Water Pumps of carrying special media, and promptly the medium carried of Under Water Pumps is a high-temp liquid, is the superhigh temperature concentrated sulphuric scid as the high temperature media of carrying, and this Under Water Pumps is also referred to as superhigh temperature concentrated sulphuric scid Under Water Pumps.Because the particularity of fed sheet of a media, require the pump can be high temperature resistant and corrosion-resistant, therefore in pump structure design and material selection, its particularity is arranged.
In recent years, sulphur-burning sulphuric acid plant has progressively been brought up to ten thousand tons/year of 60-80 for ten thousand tons/year by the 20-30 in past, and degree of depth also has been increased to 3～4 meters by 1～2 meter thereupon under the liquid of the superhigh temperature concentrated sulphuric scid Under Water Pumps supporting with it,, and also have the trend that increases.At present, the user of the superhigh temperature concentrated sulphuric scid Under Water Pumps 90% that uses on the domestic market relies on import, but the superhigh temperature concentrated sulphuric scid Under Water Pumps price of external import is expensive, and the delivery cycle is long, the service corresponding speed is slow, is seriously restricting the development of China's sulfuric acid industry large-scale plant.Existing superhigh temperature concentrated sulphuric scid Under Water Pumps mainly is made up of pump, line shaft, coupling and power source, there is following technological deficiency in this superhigh temperature concentrated sulphuric scid Under Water Pumps: 1, owing to 3～4 meters of the degree of depth under the liquid of pump (floor is to the pump center), line shaft is longer, when operation, can there be swing, and then cause bigger vibrations, make pump operation not steady.2, line shaft adopts the multistage axle to connect to form the structure of major axis, though this line shaft processing easily, but pump is very difficult in assembling, because during assembling, to link together every section axle, every section axle is all multifactor because of processing workman's technology, machine tool etc., causes locating point and reference point deviation bigger, makes pump very big bang occur easily when operation.In the time of pump operation, drive line shaft by power source (motor) and rotate, the moment peak torque that every section axle is subjected to is different, and one section line shaft wherein easily breaks.3, this pump is to use on relieving haperacidity industry low temperature reclaiming system, because the SO of certain pressure is arranged in the tower jar of its work
3Gas has many SO in 200 ℃ the concentrated sulphuric scid
3Molecule can present free state, is easy to combine with airborne water form acid mist, and this acid mist has harm to environment, can pollute water body and soil, and to very serious of the health hazard of human body, therefore the sealability to this pump has higher requirement.This pump mainly adopts packing seal, too tightly then influences the line shaft normal rotation between filler and the line shaft, and SO too greatly then can be caused in the gap between filler and the line shaft
3Gas leakage, sealing effect is poor.
The model utility content
Vibrations more greatly, steadily do not reach SO when overcoming under the existing superhigh temperature concentrated sulfuric acid solution pump operation
3The deficiency that gas is easily revealed, the utility model provides a kind of major axis superhigh temperature concentrated sulphuric scid Under Water Pumps, and this major axis superhigh temperature concentrated sulphuric scid Under Water Pumps has and operates steadily and the characteristics of good sealing effect.
The technological scheme that the utility model adopted is: a kind of major axis superhigh temperature concentrated sulphuric scid Under Water Pumps, comprise pump, line shaft, coupling and power source, power source is fixed on the adpting flange by support, be fixed with supporting sleeve on the adpting flange, the top and bottom of supporting sleeve are fixed with stuffing box body and pump respectively, line shaft is positioned at supporting sleeve, one end of line shaft connects pump, the other end links to each other with power source by coupling, be provided with stuffing box packing between stuffing box body and the line shaft, the stuffing box packing top is provided with Gland, line shaft is an integral structure, the upper fixed of stuffing box body has bearing support, rolling bearing is installed in the bearing support, is provided with first sliding bearing between line shaft and the pump, the middle part of supporting sleeve is fixed with plain bearing housing, be provided with second sliding bearing, rolling bearing between line shaft and the plain bearing housing, first sliding bearing and second sliding bearing form three point locations to line shaft; The lower end of stuffing box body is connected with sleeve, is fixed with screw-casing on the line shaft in the stuffing box body, between sleeve and the line shaft slit is arranged, and sleeve, line shaft and screw-casing surround gas storage cavity.
The surface hardness of described first sliding bearing and second sliding bearing is not less than HRC50.
The middle part, lower end of described sleeve inwardly folds into, and the slit that folds between part and the line shaft is 2mm.
The beneficial effects of the utility model are: owing to take technique scheme, rolling bearing, first sliding bearing and second sliding bearing form sight alignment, reduced the swing of line shaft, make the operation of pump stable more and reliable, adopted the combined sealing structure of screw-casing, gas storage cavity and stuffing box packing simultaneously, SO
3Gas enters into gas storage cavity from the slit between sleeve and the line shaft, and when pump operation, thread bush rotates together in company with line shaft, and thread bush produces the propelling force in gas storage cavity, and the gas pressure in the gas storage cavity is bigger, makes SO
3Gas can not enter in the gas storage cavity again, forms motive sealing.When pump stopped, thread bush was ineffective, and down twist Gland and compress stuffing box packing this moment, forms static seal, makes the probability that medium leaks outside in the pump almost nil, good sealing effect, safety, environmental protection.
