Description
Technical field
The present invention relates to a kind of axle envelope rinse-system of centrifugal pump.More particularly to a kind of sealed mechanical seal pump efficiency ring
With the axle envelope rinse-system with the pump efficiency ring.
Background technology
The API682 standard Appendix D Plays of centrifugal pump and impeller pump gland seal system sealflush plan 52,53A,
The circulation power of 53B, 53C internal liquid is provided by pump efficiency ring, prior art as shown in Figure 1.Fig. 1, Fig. 2, Fig. 3 represent existing
There are the wet sealing of packaging double-contact of technology 2CW-CW with buffer solution and 3CW-FB to collect towards in back of the body configuration with obstruct liquid
The rinse-system of the wet sealing of dress double-contact and internal structure schematic diagram.Fig. 4 represents prior art 3CW-BB with obstruct liquid
The rinse-system of the wet sealing of packaging double-contact (in API682 1.2) and internal structure schematic diagram in configuring back-to-back.Coolant
Enter from BI mouths and centrifugal force is produced due to pump efficiency ring and pump shaft synchronous rotary after annular seal space or axial force causes this part liquid
Body obtains power and moves into place b from position a, then goes out from BO mouths, and again from BI mouths after external cooler 14
Annular seal space is entered, so repeats to allow for coolant circulating liquid and flow to reach the mesh of two sets of mechanical sealing friction pairs of cooling
's；As can be seen here, if the blood circulation system for circulating system metaphor adult body of above-mentioned coolant, then pump efficiency ring
Human heart is equivalent in this system, and it is provided for the system that circulates of whole coolant as the heart of human body
Power, therefore the quality of pump efficiency ring performance just determine the quality for circulating system working effect of whole coolant.
The structure that circulate in system and operation principle of the pump efficiency ring in whole coolant in prior art.There is a lot of lacking
Point is difficult to overcome：
1st, pump efficiency ring acts as at the uniform velocity garden Zhou Yundong with pump shaft one all the time, and short tooth is produced on the maximum outer round surface of pump efficiency ring,
Due to profile of tooth very short so all liq that is contained in short tooth is almost in same equipotential surface and makees at the uniform velocity garden Zhou Yundong, that is,
Say that liquid is once entered in short tooth, no matter this partially liq stop in short tooth how long the size of its speed all without having
Any increase is：Position a is identical with the size of 2 points of flow rate of liquid of position b, and in other words pump efficiency ring now does not play acceleration and makees
With.
2nd, because tooth is short liquid volume is little between two teeth, cause flow little.
3rd, the distance that is passed through in annular seal space due to fluid is short, that is to say, that path is short, so only fluid is through portion
Position very small part liquid participates in flowing, and most of liquid is remained static all the time, and two sets of mechanical sealing friction pairs are most to need
Where being cooled down, but neighbouring cooling liquid is always at relative static conditions, and this state is to mechanical seal
Speech is quite unfavorable.
4th, liquid of this small gangs of flowing need to overcome come from liquid viscosity, stationary parts, friction, along journey, turning, section
The impact of multiple resistances such as stream, backflow, vortex causes lift to diminish, or even comes to a halt.
5th, in order to produce effective lift, reduce backflow, improve drive efficiency it is necessary to will be maximum outer for the pump efficiency ring being rotating
As close possible to static cavity inner wall, the part liquid that its result is allowed between moving component and stationary parts bears pole in footpath
Big shearing force, not only power consumption, produce waste heat, or even destruction liquid molecular structure and affect liquid physically stable
Property and chemical stability.
6th, the gap between the static cavity inner wall of pump efficiency ring due to being rotating is little, so it occur frequently that interfering and causing machine
Tool seal failure.
7th, the gap between the static cavity inner wall of pump efficiency ring due to being rotating is little, so improve machining accuracy and assembling
The requirement of precision, while also shortening the operating wear-out period, reduces service life, increases cost.
8th, because flow path of the fluid in annular seal space be short, area of passage is little, cooling effect is poor.
9th, fluid passage is that the open direction for causing flowing is random and cause turbulent flow so that most of liquid flowing is slowly
Or even transfixion.
There is no flow, the pressure gauge formula of maturation when the 10th, designing pump efficiency ring, can only estimated data by rule of thumb.
11st, the flow and pressure of circulation of fluid cannot be adjusted by the method for the geometric parameter of change pump efficiency ring effectively
Difference.So cannot active accommodation thermal balance.
12nd, the relatively low pump (n of rotating speed<During 1000rad/min) it is extremely difficult to effect.
