Five, embodiment
Below in conjunction with accompanying drawing, brief description is made to the specific embodiment of the present invention.
Embodiment:
Composition graphs 1 and Fig. 4, be provided with the guide rod assembly 9 of two groups of symmetries in the both sides, waterexit end of full through-flow submersible pump 3, guide rod assembly 9 is that stifle 11, cylinder 12 and platter 13 are welded into entirety.
Composition graphs 5, guiding suspension member 5 first thrust inclined-plane 17 and base plate 18 and a dividing plate 15 is welded into an entirety, make base plate 18 vertical with dividing plate 15, the angle that thrust inclined-plane 17 and base plate 18 are formed is 180 ° of-α ± 1 °, and ensure that the water-in flange face in water-output flange face and built-in pipe 7 that guide rod assembly 9 slowly comes downwards to full through-flow submersible pump 3 along thrust inclined-plane 17 in coupling process overlaps completely, enough Safe Vertical Distances are also had with base plate 18, to avoid coupling not in place bottom the cylinder 12 of guide rod assembly 9.Weld with gusset 16, another dividing plate 15, four little support muscle 14 respectively again.
Composition graphs 1 and Fig. 2, built-in pipe 7 both sides arrange position shelf 6 and the guiding suspension member 5 of two cover symmetries respectively, and three is welded into an entirety, by this integral built-in on the concrete dividing pier 4 and waterwall 8 of water inlet flow channel.When hoist is sling full through-flow submersible pump 3, the two ends of the cylinder 12 stretched out from guide rod assembly 9 through guiding port 1 enter guide assembly 2, full through-flow submersible pump 3 is with water outlet posture vertically downward, along guide assembly 2 slide downward, the cylinder 12 stretched out to guide rod assembly 9 contacts with the thrust inclined-plane 17 in the guiding suspension member 5 be embedded on concrete dividing pier 4, under the effect of pump housing weight, cylinder 12 in guide rod assembly 9 also can continue down to slide, until the water-output flange face of full through-flow submersible pump 3 overlaps completely with the water-in flange face of built-in pipe 7, trapezoidal folder cloth O type rubber seal 10 is compacted, pump stops sliding, coupling puts in place.At this moment guide rod assembly 9 hangs on thrust inclined-plane 17, tangent with it.The axial thrust load Fx of pump housing active force is compressed to the trapezoidal folder cloth O type rubber seal 10 of built-in pipe 7 and pump housing waterexit end, form the sealing of outlet passage.The gravity G that full through-flow submersible pump 3 is subject to, the counter-force Fy on the cylinder 12 of the elastic force Fr that trapezoidal folder cloth O type rubber seal 10 is compressed and ramp effect forms a level-crossing power system.
For ensureing that dividing pier inclined-plane thrust self coupling mounting type is stable under operation, just should meet and being greater than axial force F a, i.e. Fx=Gtan α > Fa because of inclined-plane generation x direction component Fx suffered by concrete dividing pier 4; As can be seen from the above equation, as long as increase the angle α of thrust inclined-plane and level, meet surely with regard to one, but work as the friction self-locking angle β=tan of 90 ° of-α≤O type rubber seal and iron and steel
-1(0.18) when=10.2 °, can self-locking be there is, make suspending pump that difficulty occur.Therefore, when engineering design, stability criterion value be
safety coefficient k=2.5.Certain pumping plant 1400QGWZ-5.64/8.54-50-670KW full through-flow submersible pump, D
leaf=120cm, D
h=57.6cm, G=11800kg, safety coefficient k=2.5,
namely be 26.5 ° with the angle along vertical line, getting α when engineering drawing makes is 24 °, is the stability foundation ensureing that trapezoidal folder cloth O type rubber seal 10 is not swashed, do not thrown off.
Can find out as engineer applied, the span of α is 15 ° ~ 30 °, and can draw the system stability analysis this level-crossing power system being carried out to theoretical; Draw guide rod assembly 9 central position so that the upper and lower sealing force that is coupled is equal for optimization aim, be coincide as the best with the facade central position of full through-flow submersible pump 3, be arranged in the certain area of the first quartile at this center.Mechanics stability analysis is calculated as follows:
For ensureing that thrust self coupling mounting type is stable under operation, following theoretical mechanics condition should be met:
∑T＝0G·x2＝Fy·x1+Fx·y2-Fr·r-Fa·r——————①
∑Fx＝0Fx＝Fa+Fr——————②
The end thrust of Fa-----axial-flow pump
The elastic force of Fr-----trapezoidal folder cloth O type rubber seal compression
By ∑ Fx=0, known, as Fx > Fa, the elastic force Fr of residue and the compression of trapezoidal folder cloth O type rubber seal.
As Fa=0, namely obtain Fx=Fr by 2. formula, substitute into 1. formula
G·x2＝Fy·x1+Fr·y2-Fr·r
＝Fy·x1+Fry2-r
＝Fy·x1+Fxy2-r——————③
Fx=Fsin α Fy=Fcos α------4. as shown in Figure 1
4. formula substitutes into 3. formula and obtains
G·x2＝F·cosα·x1+F·sinα·y2-r
As most simple scenario, as y2=r, then
From 5. formula, α is larger, and x1 is less, and F is larger.
4. Shi Ke get is substituted into by 5. formula
From 2. formula, the X-direction component that the gravity of the pump housing own produces because of inclined-plane, when pump off-duty, Fa=0, Fx=Fr, namely Fx balance by the elasticity of trapezoidal folder cloth O type rubber seal; When water pump operation, the axial force F a that pump produces, its direction is contrary with Fx direction, and owing to creating the axial force of operation, pressing 2. formula Fr will reduce, and when Fr is reduced to 0, illustrate that sealing surface is open, seal failure.
When y2 be on the occasion of, as shown in Figure 1, the sealing counter-force that the upper and lower limit of trapezoidal folder cloth O type rubber seal provides is relevant with the size of y2.
The sealing counter-force that the trapezoidal folder cloth O type rubber seal in upside provides is:
The sealing counter-force that the trapezoidal folder cloth O type rubber seal in downside provides is:
Therefore, when y2 ≠ 0, judge the stability criterion whether sealing surface is opened is whether the trapezoidal folder cloth O type rubber seal in downside is opened, and the axial force of obvious water pump operation, it is rational for being divided into upper and lower each half.
6. namely thrust self coupling sealing means is stable for formula, the Universal Criterion that sealing surface is not opened.
To notice that outlet conduit flange width has enough width when designing, when there is axial deformation in trapezoidal folder cloth O type rubber seal (8), the pump housing flanged surface at place is when fulcrum rotates, should ensure that trapezoidal folder cloth O type rubber seal (8) does not exceed the width of flange, be then stable.If when designing, getting x1=x2, during y2=r, then can thoroughly solve this worry.Now 6. stability criterion formula is also simplified to
G·tanα>F
a——————⑦
Meet stable condition formula 7., as long as increase the angle α of thrust inclined-plane and level, meet surely with regard to one, but work as the friction self-locking angle β=tg of 90 ° of-α≤O type rubber seal and iron and steel
-1(0.18) when=10.2 °, can self-locking be there is, make suspending pump that difficulty occur.Therefore, when engineering design, stability criterion value be
Safety coefficient k=2.5.

namely be 26.5 ° with the angle along vertical line, getting α when engineering drawing makes is 24 °, is the stability foundation ensureing that trapezoidal folder cloth O type rubber seal is not swashed, do not thrown off.Can find out as engineer applied, the span of α is 15 ° ~ 30 °, and can draw the system stability analysis this level-crossing power system being carried out to theoretical; Draw guide rod assembly central position so that the upper and lower sealing force that is coupled is equal for optimization aim, be coincide as the best with the facade central position of full through-flow submersible pump, be arranged in the certain area of the first quartile at this center.
