Abstract
The utility model discloses a submerged centrifugal pump of high-temperature concentrated sulfuric acid. The centrifugal pump comprises a suction pipe, a pump cover, a pump body, an impeller, pump spindles, a spindle sleeve, a bushing, a connecting pipe, an outlet pipe, a base, a sealing part, a bearing block, a motor base, a coupling and a bearing and is characterized in that the pump spindle at the top end of the connecting pipe is provided with an angular contact ball bearing, and the pump spindle at the upper part of the pump cover is provided with a pair of sliding bearings comprising the combination of the spindle sleeve and the bushing. By adopting the double supporting structures of the contact ball bearing and the sliding bearing, the centrifugal pump can bear radial load, thus enhancing the quality of pumps, prolonging the service life of products and improving the operating efficiency.
Description
Technical field
The utility model belongs to a kind of pump, specifically is a kind of high-temperature concentrated sulfuric acid submerged centrifugal pump.
Background technique
The high-temperature concentrated sulfuric acid submerged centrifugal pump is that one step single sucking axially sucks radially subdivision blade type submerged centrifugal pump, be mainly used in drying and the conveying that absorbs the circulatory system and the finished product concentrated sulphuric scid in the gas washing in SA production, for delivery temperature t≤110 ℃, sulfuric acid concentration be 93%～98% concentrated sulphuric scid or 〉=usefulness of 105% fuming acid.But it is more and more higher that domestic sulfuric acid production process requires, and existing product aspect such as from waterpower to the structure can not satisfy the demand of the quality of production and efficient gradually, and the product quality that improves the high-temperature concentrated sulfuric acid submerged centrifugal pump becomes the active demand in market.
The model utility content
The purpose of this utility model provides a kind of high-temperature concentrated sulfuric acid submerged centrifugal pump, can strengthen the quality of pump, has prolonged product working life, improves operating efficiency.
The technical solution of the utility model is as follows:
The high-temperature concentrated sulfuric acid submerged centrifugal pump, include suction pipe, pump cover, the pump housing, impeller, pump shaft, axle sleeve, lining, connecting tube, drain pipe, base, sealed member, bearing support, motor cabinet, coupling, bearing, it is characterized in that on the pump shaft of described connecting tube top angular contact ball bearing being installed, a pair of sliding bearing that contains axle sleeve, lining combination is installed on the pump shaft of described pump cover top.
Described sliding bearing adopts the Langaloy material to make.
Liquid level is higher than more than the pump housing center line 300mm in the acid jar before operation, in the running in the acid jar liquid level be higher than under the situation that suction pipe sucks face 300mm, the length of described suction pipe rises to the suitable length that is less than or equal to 800mm.
The utility model adopts the double supporting structure of contact ball bearing and sliding bearing, can bear radial load, thereby strengthens the quality of pump, has prolonged product working life, improves operating efficiency.That can utilize pump in the using process self inhales journey, increases the length of suction pipe, makes insertion depth increase under the pump complete machine liquid.Sliding bearing adopts the Langaloy material, has good heat resistanceheat resistant expansion characteristics, adapts to the hot environment operation, and the concentrated sulphuric scid of carrying by pump is lubricated simultaneously, has good lubricity.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The high-temperature concentrated sulfuric acid submerged centrifugal pump, include suction pipe 1, pump cover 2, the pump housing 3, impeller 4, pump shaft 5, axle sleeve 6, lining 7, connecting tube 8, drain pipe 9, sealed member 10, bearing support 11, motor cabinet 12, coupling 13, it is characterized in that on the described connecting tube 8 top pump shafts 5 angular contact ball bearing 14 being installed, a pair of sliding bearing 15 that contains axle sleeve 6, lining 7 combinations is installed on the described pump cover 2 top pump shafts 5.Sliding bearing 15 adopts the Langaloy materials to make, and has good heat resistanceheat resistant expansion characteristics, and the concentrated sulphuric scid of carrying by pump lubricated has good lubricity.
Liquid level is higher than more than the pump housing 3 center line 300mm in the acid jar before operation, in the running in the acid jar liquid level be higher than under the situation that suction pipe 1 sucks face 300mm, the length of suction pipe 1 rises to the suitable length that is less than or equal to 800mm, makes insertion depth increase under the pump complete machine liquid.
