Description

Sealed mechanical seal pump efficiency ring and the shaft seal rinse-system with this pump efficiency ring

Technical field

The present invention relates to a kind of shaft seal rinse-system of centrifugal pump.Particularly relate to a kind of sealed mechanical seal pump efficiency ring and the shaft seal rinse-system with this pump efficiency ring.

Background technique

Sealflush plan 52 at the API682 standard Appendix D Plays of centrifugal pump and rotor pump gland seal system, the circulation power of 53A, 53B, 53C internal liquid provides by pump efficiency ring, prior art as shown in Figure 1.Fig. 1, Fig. 2, Fig. 3 represent prior art 2CW-CW with buffer solution collection dress double-contact wet sealing and 3CW-FB with intercept liquid towards the back of the body configuration in collection dress double-contact wet sealing rinse-system and internal structure schematic diagram.Fig. 4 represents that prior art 3CW-BB is with wet rinse-system and the internal structure schematic diagram sealing (in API682 1.2) of collection dress double-contact in the configuration back-to-back of obstruct liquid.Cooling liquid enters from BI mouth and to produce centrifugal force or axial force after Seal cage due to pump efficiency ring and pump shaft synchronous rotary and make this part liquid obtain power from position a to move to position b, then go out from BO mouth, and after external cooler 14, enter Seal cage from BI mouth, repetition like this just make liquid circulation flow of fluid get up to reach object that mechanical sealing friction pairs is overlapped in cooling two; As can be seen here, if the blood circulation system of the system that circulates of above-mentioned cooling liquid metaphor adult body, so pump efficiency ring is just equivalent to human heart in this system, its circulate system for whole cooling liquid the same as the heart of human body provides power, and therefore the quality of pump efficiency ring performance just determines the quality circulating system works effect of whole cooling liquid.

In prior art, pump efficiency ring circulates structure in system and working principle in whole cooling liquid.A lot of shortcoming is had to be difficult to overcome:

1, pump efficiency ring makes at the uniform velocity garden Zhou Yundong together with pump shaft all the time, short tooth is produced on the maximum outer round surface of pump efficiency ring, because profile of tooth is very short so all liq be contained in short tooth is almost in same equipotential surface make at the uniform velocity garden Zhou Yundong, that is liquid is once enter in short tooth, namely the size that this part liquid stops how long its speed in short tooth does not have any increase: position a is identical with the size of position b 2 flow rate of liquid, and in other words pump efficiency ring does not now play acceleration.

2, because tooth short between two teeth liquid volume little, cause flow little.

3, due to fluid in Seal cage the distance of process short, that is path is short, so only have fluid, through position, very little a part of liquid participates in flowing, major part liquid remains static all the time, two cover mechanical sealing friction pairs need most the place obtaining cooling, cooling liquid is always in relative static conditions, and this state is quite unfavorable for mechanical seal.

4, the liquid of this small gangs of flowing needs to overcome to come from fluid viscosity, static part, friction, along the impact of the multiple resistances such as journey, turning, throttling, backflow, eddy current, lift is diminished, and even comes to a halt.

5, in order to produce effective lift, reducing backflow, improve drive efficiency, will by the pump efficiency ring maximum outside diameter that is rotating as far as possible close to static cavity inner wall, its result just makes the part liquid between moving element and static part bear great shearing force, not only consumed power, generation waste heat, even destroy the structure of molecule of liquid and affect liquid physical stability and chemical stability.

6, the gap between the static cavity inner wall of the pump efficiency ring owing to being rotating is little, so usually interfere and cause mechanical seal to lose efficacy.

7, the gap between the static cavity inner wall of the pump efficiency ring owing to being rotating is little, so improve the requirement of machining accuracy and assembly precision, also shortens the running wear-out period simultaneously, reduces working life, increase cost.

8, because the flow path of fluid in Seal cage is short, area of passage is little, so cooling effect is poor.

9, fluid passage is that turbulent flow is caused at random in the open direction making to flow, and makes the slow even transfixion of most of flow of fluid.

Ripe flow, pressure meter formula is not had when 10, designing pump efficiency ring, can only data estimator by rule of thumb.

11, flow and the pressure difference of circulation of fluid effectively cannot be adjusted by the method for the geometric parameter changing pump efficiency ring.So just can not active accommodation thermal equilibrium.

12, the pump (during n<1000rad/min) that rotating speed is lower is difficult to be effective.

All that the shaft seal rinse-system of centrifugal pump has problem to be solved above.
