Description
Technical field
The present invention relates to a kind of lined oil-slurry pump, particularly relate to a kind of lined oil-slurry pump and assembling thereof and liner weares and teares
Monitoring method, it is adaptable to high temperature, the petrochemical plant of high pressure and routine need to carry the device of abrasive solids thing.
Background technology
Traditional conveying vane type centrifugal pump containing abrasive solids granule, the following 3 kinds of technical schemes of main employing: a kind of
It is directly to use hard wear-resistant material such as white cast-iron as pressure part, including pressure-bearing volute casing, front liner plate, rear lining plate etc., outside
Parcel outer shell construction part is used for installing and coupling.
The shortcoming of this structure is, owing to White Cast Iron Material hardness is high, casting fluidity is poor, is easily generated shrinkage cavity, crackle
Etc. casting flaw, and it is difficult to soldering, it is therefore necessary to it is thicker that housing wall thickness designs；It is difficult to screwed hole on white iron, needs
Shell body by conventional material manufacture carries out coupling installation and sealing compression fastening.Therefore, size as this kind of pump is relatively big and stupid
Weight, and it is easily generated the fragility white cast-iron of shrinkage cavity defect itself as pressure part owing to using, it is impossible to it is used for carrying inflammable and explosive
High temperature slurry oil, be only used for carry general aspects slurry.
Another kind such as number of patent application 200610040604.4, is to use conventional metal material to manufacture pump case, at metal watch
Face utilizes the antifriction alloy or ceramic material that the attached last layer of surface spraying technology is thin.This kind of pump configuration is simple, although may be used for
The conveying of high temperature slurry oil, but owing to the abrasion of medium is big, very thin one layer is just ground away after being over by mill housing itself, finally leads
Cause whole pump case to need to change；And the adhesion with matrix of sprayed on material is poor, and with the thermal expansion factor of matrix material not
With, at high temperature there is swollen difference, produce crack, easily the high speed at pumped (conveying) medium is washed away lower peeling and was lost efficacy, and therefore the life-span is relatively
Short.
Such as the one more conventional in oil-slurry pump of number of patent application 201420059863.1, it is shell body and front and back pump
This structure of structure that lid pressure-bearing, inner housing are wear-resisting solves the contradiction of material wear-resistant and pressure-bearing, and inner housing uses high hardness wear-resisting
Material bear impeller rotate brought wash away, shell body use conventional metal material bear internal pressure, both ensured that pressure-bearing is close
Envelope reliability, also ensure that wear-resisting service life, it is adaptable to the operating mode of high temperature conveyer belt solid particle simultaneously.The shortcoming of this structure
It is, owing to, in whole inner spiral casing body shell body to be encased in, the outside dimension of inner housing is relatively big, to add fixing outside its inner housing
The structure position that need to take by structure, the internal diameter of required shell body also to increase, according to the computing formula of pressure part, as
In 3 grades of parts of ASME BPVC-III standard ND bundling, ND3441.1 clause is about the computing formula " t=of pump case minimum wall thickness (MINI W.) t
(PA)/S " (formula 1, in formula, P is chamber pressure, and A is pressure-bearing pump case intracavity diameter, and S is allowable stress), radial thickness and diameter
Be directly proportional, under bearing same pressure, the wall thickness of the wall ratio conventional pumps of shell body is much greater, simultaneously shell body side
Weight m=π/4*A2* t (formula 2), i.e. to square being directly proportional of diameter, is directly proportional to wall thickness；By computing formula 1 generation of wall thickness t
Enter in formula 2, available weight computing formula m=π/4*A2* P*A/S=π * A3/ (4S), i.e. pump cover side weight and pressure-bearing shell
3 powers of intracoelomic cavity diameter are directly proportional.For pump cover, originally have only to the impeller to load with only coordinating between pump cover
Mouthful, need the external diameter increasing to not less than runner volute casing part, bearing area increases, the pressure gain born and diameter square
Being directly proportional, according to pressure-bearing end cap computing formula, in 3 grades of parts of ASME BPVC-III standard ND bundling, ND3325.2 clause closes
Computing formula in pump cover minimum wall thickness (MINI W.) t(formula 3, in formula, C is coefficient, and d is straight with pump housing sealing surface
Footpath), this makes the wall thickness of pump cover also be directly proportional to diameter, and the wall thickness of more conventional pump increases more, and formula 3 substitutes into circular pump cover
In computing formula, its weightI.e. pump cover weight
Also 3 powers to the diameter increased are directly proportional.Hold because the stud of connection pump cover with shell body is acted on pump cover by chamber pressure
Pressure surface area is directly proportional, and area is directly proportional to pressure-bearing surface diameter, therefore the loaded area of stud and pump cover and pump housing seam portion
Square being directly proportional of the diameter of position.The increase of seam diameter also makes the stud quantity coupling pump cover and shell body increase or directly
Footpath increases, to bear the pressure added.Therefore, the overall dimensions of this kind of pump is big, heavy, and manufacturing cost is higher.
Simultaneously as interior volute casing is in inside shell body, the abrasion condition of inside be can't see in outside, when inner housing weares and teares
After, medium starts to wash away shell body, until abrasion penetrates shell body and finds just to know during leakage, but now as pressure-bearing shell
Shell body is also scrapped because of abrasion, for high temperature slurry oil, there is serious potential safety hazard, reveals easily to cause firing thing
Therefore.Currently used method the most rule of thumb increases maintenance number of times and avoids shell body mill leakage loss bad, adds the cost of overhaul
With with unnecessary shutdown.
Summary of the invention
The present invention mainly solves the deficiencies in the prior art, it is provided that a kind of compact conformation, and weight and volume is little, knot
