Abstract
The invention relates to a high-pressure process pump which is composed of a pump body, a pump cover, a closed impeller and the like, wherein a pump shaft is arranged in the pump body; the pump body is connected with a bearing frame by virtue of the pump cover, and the bearing frame is provided with an air cooling blade; the blades of the closed impeller are a vertical blade and a circular arc blade; a seal cavity is formed between the pump cover and the bearing frame, a assembling mechanical seal with a cooling fluid is arranged in the seal cavity in a radial direction. According to the high-pressure process pump provided by the invention, the defects that the lift of a general centrifugal pump is low, the efficiencies of a peripheral pump, a flow cutting pump and a reciprocating pump are low are overcome; and the high-pressure process pump can reach the design requirement of high lift and high efficiency and has wide market prospect and popularization value.
Description
Technical field
The present invention relates to a kind of small flow, high-lift one pole chemical pump, particularly a kind of high pressure process pump.
Background technique
Peripheral pump, reciprocating pump and multistage centrifugal pump are applied to fields such as petrochemical industry, smelting, power plant, papermaking, environmental protection, iron and steel cold-rolling pickling, electronic mesh, bio-pharmaceuticals, its application area is wide, but owing to peripheral pump, reciprocating pump are installed inconvenient, lift is low, efficient is low, rotating liquid friction in impeller of the prior art and the pump case strengthens, loss the working life of impeller, be unfavorable for the utilization efficiency of pump; General in addition peripheral pump, reciprocating pump and multistage centrifugal pump can not reach temperature controlling to the liquid in the pump housing according to the needs of medium, have reduced the quality of product.
Summary of the invention
The object of the present invention is to provide a kind of new and effective, small flow, high-lift single-stage chemical pump, the process pump that prolongs working life of pump and also raise the efficiency simultaneously.
The technological scheme that realizes the object of the invention is: the present invention includes a kind of high pressure process pump, and by the pump housing, pump cover, formations such as double shrouded wheel are provided with pump shaft in the described pump housing; The described pump housing is connected with bearing bracket stand by pump cover, and bearing bracket stand is provided with air-cooled blade.
Above-mentioned a kind of high pressure process pump, the blade of described double shrouded wheel adopts prismatic blade and curved blade.
Above-mentioned a kind of high pressure process pump describedly forms Seal cage between pump cover and bearing bracket stand, band cooling liquid machine for the assembly of unit load tool sealing radial arrangement is in described Seal cage.
Above-mentioned a kind of high pressure process pump, the cross section of fluid channel of the described pump housing are the ring pump chamber structure of tangential outlet.
The present invention has following characteristics: (1) is to install in pump cover, sealing, bearing bracket stand position design cooling (liquid) according to the medium needs, and can design radially fan blade (air cooling equipment) at the bearing bracket stand position, to the cooling of bearing bracket stand, Seal cage, make the type pump serviceability temperature reach 250 ℃ so simultaneously.
(2) blade of double shrouded wheel adopts prismatic blade and curved blade, has reduced to have prolonged the working life that contains particle or slurry pump for conveying because of friction relatively causes wearing and tearing to impeller, and the assurance pump can efficiently move for a long time.This structure is than similarly peripheral pump, reciprocating pump are easy for installation on the market, the high 15-25% of efficient.

Embodiment
See a kind of high pressure process pump of Fig. 1, by the pump housing 1, pump cover 3, double shrouded wheel 2 formations such as grade are provided with pump shaft 4 in the described pump housing 1; The described pump housing 1 is connected with bearing bracket stand 6 by pump cover 3, and bearing bracket stand 6 is provided with air-cooled blade 7; Form Seal cage between pump cover 3 and bearing bracket stand 6, band cooling liquid machine for the assembly of unit load tool seals 5 radial arrangement in described Seal cage; The cross section of fluid channel of the described pump housing 1 is the ring pump chamber structure of tangential outlet.The blade of seeing Fig. 2 double shrouded wheel 2 adopts prismatic blade 9 and curved blade 8, not relative basically mobile between rotating liquid in the pump case and the impeller, impeller inlet liquid is transported to the prismatic blade runner through circular arc vane, through action of centrifugal force liquid is done work, impeller outlet place liquid is dished out at a high speed along tangent line, and the liquid in the impeller is done concentric rotation from inside to outside by different level by the energy height.
Obviously, the above embodiment of the present invention only is for example of the present invention clearly is described, and is not to be qualification to embodiments of the present invention.For those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present invention extended out and still are among protection scope of the present invention.
