Technical Field
The utility model relates to an oil slurry pump field especially relates to an oil slurry pump is used to petroleum refining suspension bed device.
Background
In a suspension bed device adopted in the petroleum refining industry at present, the concentration of oil slurry particles is 10-30%, the diameter of hard particles is 0.1-1mm, and the high temperature is between 180 ℃ and 350 ℃; a flow rate of 3-160m is required3The conventional slurry pump is mainly applied to a catalytic cracking device of a refinery and mainly adopts a closed impeller design; under the working condition, the operation port is fast to change and wear, and the efficient operation time is short; short equipment maintenance period and the like.
The single-stage centrifugal pump of ordinary structure is generally used as a substitute, and has the disadvantages of low efficiency, serious abrasion, unreasonable structure and expensive component replacement. If the parts which are easy to wear are simply thickened, the difficulty of drilling and threading after the parts such as the pump shell and the like are made of high wear-resistant alloy materials is increased.
Disclosure of Invention
The utility model discloses an oil refining suspended bed slurry pump for device is guaranteeing under the prerequisite of enough structural strength, through structural improvement, realizes that transport and structural strength to the slurry oil are high, the effect of easily changing resistance to wears.
For realizing above-mentioned technological effect, this application discloses a petroleum refining suspension bed slurry pump for device, including import pump cover, pump case and pump cover, still be equipped with the pump shaft, pump shaft one end be equipped with the impeller, by hold with in the space that import pump cover, pump case and pump cover are constituteed, the antifriction plate before the import pump cover inboard is equipped with, the pump cover inboard is equipped with the back antifriction plate.
Furthermore, a half flange is arranged at the upper part of the pump shell. Through the arrangement of the halving flange and the pump shell, the effect that the pump shell is not opened is realized.
Furthermore, the inlet pump cover and the pump cover are made of common wear-resistant alloy materials.
Furthermore, the pump shell is made of high-abrasion-resistance alloy materials.
Further, the impeller is a semi-open impeller.
Furthermore, the adjustable bearing support component is also included.
Further, a shaft seal component is arranged on a pump shaft in the oil slurry pump.
Furthermore, an anti-backflow graphite ring is further arranged between the inlet pump cover and the front wear-resisting plate.
The beneficial effects of the utility model include:
the invention discloses a slurry pump, which is characterized in that the flow passage component of the original slurry pump is made of high-wear-resistant materials, and front and rear wear-resistant plates made of high-wear-resistant materials and convenient to replace are designed, wherein the pump shell and the wear-resistant plates are designed according to the casting process characteristics of the materials. The problem of not drilling structural design is solved, the processing degree of difficulty has been reduced.
The original closed impeller is changed into a semi-open impeller, the thickness of the blade is thicker than that of the closed impeller by more than 30%, and the bearing box body adopts a shaft item adjustable structure, so that the hidden troubles of blockage prevention due to high-concentration running of the impeller and high-efficiency running time due to abrasion of a pump body opening ring are solved; the use requirement of the slurry pump of the suspension bed device of the new petroleum refining process at present is met.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below. It is obvious that the drawings in the following description are some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.
