Some little support muscle 14 are provided with plate 19, the fixed plate 19 and the size of dividing plate 15 being arranged on same locating rack 6 is identical
And identical highly parallel to each other.
It is first thrust inclined-plane 17 and base plate 18 and a dividing plate 15 to be welded into into an entirety to be oriented to suspension member 5, makes 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 is ensured in coupling process
Guide post component 9 enters water law along what thrust inclined-plane 17 slowly came downwards to the water-output flange face of full through-flow submersible pump 3 and built-in pipe 7
Blue face is completely superposed, and the bottom of cylinder 12 and the base plate 18 of guide post component 9 also have enough Safe Vertical Distances, to avoid coupling
It is not in place.Again respectively support muscle 14 little with gusset 16,15, four, another dividing plate is welded.
With reference to Fig. 1 and Fig. 2, the both sides of built-in pipe 7 are respectively provided with two sets of symmetrical locating racks 6 and are oriented to suspension member 5, three's welding
Into an entirety, by this integral built-in on the concrete dividing pier 4 and waterwall 8 of water inlet flow channel.Sling when crane and pass through entirely
Stream submersible pump 3, the two ends of the cylinder 12 that channeled mouth 1 stretches out from guide post component 9 enter guide assembly 2, full-tubular diving
Posture of the electric pump 3 with outlet vertically downward, along the slide downward of guide assembly 2, the cylinder 12 stretched out to guide post component 9 with
The thrust inclined-plane 17 being oriented in suspension member 5 being embedded on concrete dividing pier 4 is contacted, in the presence of pump housing weight, guide post group
Cylinder 12 in part 9 also may proceed to down slide, the water-output flange face and the water inlet of built-in pipe 7 until full through-flow submersible pump 3
Flange face is completely superposed, and the trapezoidal O-shaped rubber seal 10 of cloth of pressing from both sides is compacted, and pump stops sliding, and coupling is in place.At this moment guide post group
Part 9 is hung on thrust inclined-plane 17, tangent.Axial thrust load Fx compression built-in pipes 7 and pump housing water side to pump housing active force
The O-shaped rubber seal 10 of trapezoidal folder cloth, formed outlet passage sealing.The gravity G that full through-flow submersible pump 3 is subject to, it is trapezoidal
Counter-force Fy in O-shaped elastic force Fr of the compression of rubber seal 10 of folder cloth and the cylinder 12 of ramp effect constitutes a level-crossing
Power system.
To ensure that dividing pier inclined-plane thrust self coupling mounting means is under operation stable, just should meet concrete every
It is more than axial force F a, i.e. Fx=Gtan α > Fa because inclined-plane produces x directions component Fx suffered by pier 4;Can from above formula
Go out, as long as increase thrust inclined-plane and the angle α of level, surely meet with regard to one, but when 90 ° of-α≤O-shaped rubber seal and steel
Friction self-locking angle beta=the tan of ferrum-1=10.2 ° (0.18) when, it may occur that self-locking, there is suspending pump difficult.Therefore set in engineering
Timing, be stability criterion valueSafety coefficient k=2.5.Certain pumping plant 1400QGWZ-5.64/8.54-
50-670KW full through-flow submersible pumps, DLeaf=120cm, Dh=57.6cm, G=11800kg, safety coefficient k=2.5,It it is 26.5 ° i.e. with the angle along vertical line, engineering drawing takes α when making
It is to ensure the stability foundation that the O-shaped rubber seal 10 of trapezoidal folder cloth is not swashed, do not disengaged for 24 °.
It can be seen that used as engineer applied, the span of α is 15 °~30 °, it is possible to drawn to this level-crossing power system
Carry out the system stability analysis of theoretical;To couple, upper and lower sealing force is equal to draw guide post component 9 as optimization aim
Center, is coincided as optimal, first quartile of the arrangement at this center with the facade center of full through-flow submersible pump 3
Certain area in.Mechanics stability analysis is calculated as follows:
To ensure that thrust self coupling mounting means is under operation stable, following rational mechanics condition should be met:
∑ T=0 Gx2=Fyx1+Fxy2-Frr-Far --- --- is 1.
∑ Fx=0 Fx=Fa+Fr --- --- is 2.
The axial thrust of Fa----- axial-flow pumps
The elastic force of the O-shaped rubber seal compression of the trapezoidal folder cloth of Fr-----
By ∑ Fx=0, it is known that, as Fx > Fa, residue is elastic force Fr of the O-shaped rubber seal compression of trapezoidal folder cloth.
As Fa=0, i.e., Fx=Fr is obtained by 2. formula, substitute into 1. formula
Gx2=Fyx1+Fry2-Frr
=Fyx1+Fry2-r
=Fyx1+Fxy2-r --- --- is 3.
As shown in Figure 1 Fx=Fsin α Fy=Fcos α --- --- are 4.
4. formula substitutes into 3. formula and obtains
Gx2=Fcos α x1+Fsin α y2-r
As most simple scenario, such as y2=r, then
From 5. formula, α is bigger, and x1 is less, and F is bigger.
4. Shi Ke get is substituted into by 5. formula
From 2. formula, the X-direction component that pump housing gravity itself is produced because of inclined-plane, in pump off-duty, Fa=0, Fx=
Fr, i.e. Fx are balanced by the elasticity of the O-shaped rubber seal of trapezoidal folder cloth;When water pump operation, axial force F a that pump is produced, its side
To axial force in opposite direction with Fx, due to generating operation, will reduce by 2. formula Fr, when Fr is reduced to 0, illustrate sealing surface
It is open, seal failure.
When y2 is on the occasion of as shown in figure 1, the sealing counter-force and y2 of the upper and lower side offer of the O-shaped rubber seal of trapezoidal folder cloth
Size it is relevant.
The sealing counter-force that the upside O-shaped rubber seal of trapezoidal folder cloth is provided is:
The sealing counter-force that the downside O-shaped rubber seal of trapezoidal folder cloth is provided is:
Therefore, when y2 ≠ 0, judge that the stability criterion whether sealing surface is opened is that the O-shaped rubber of the trapezoidal folder cloth in downside is close
Whether seal is opened, it is clear that the axial force of water pump operation, and it is rational to be divided into upper and lower each half.
6. formula is that thrust self coupling sealing means are stable, the Universal Criterion that sealing surface is not switched on.
In design it is noted that outlet conduit flange width has enough width, when the O-shaped rubber seal (8) of trapezoidal folder cloth
During generation axial deformation, the pump housing flange face at place around fulcrum rotate when, should ensure that the O-shaped rubber seal (8) of trapezoidal folder cloth not
Then it is stable beyond the width of flange.If in design, taking x1=x2, during y2=r, then this worry can be thoroughly solved.
Now 6. stability criterion formula is also simplified to
G·tanα>Fa——————⑦
Meet steady-state conditionss formula 7., as long as increase thrust inclined-plane and the angle α of level, surely meet with regard to one, but work as
Friction self-locking angle beta=the tg of 90 ° of-α≤O-shaped rubber seal and iron and steel-1=10.2 ° (0.18) when, it may occur that self-locking, lifting is made
Pump occurs difficult.Therefore in engineering design, it is stability criterion valueSafety coefficient k=2.5.
Certain station 1400QGWZ-5.64/8.54-50-670, DLeaf=120cm, Dh=57.6cm, G=11800kg safety coefficient
K=2.5,It is 26.5 ° i.e. with the angle along vertical line, engineering drawing system
As when take α for 24 °, be to ensure the stability foundation that the O-shaped rubber seal of trapezoidal folder cloth is not swashed, do not disengaged.It can be seen that making
For engineer applied, the span of α is 15 °~30 °, it is possible to show that the system for carrying out theoretical to this level-crossing power system is steady
Qualitative analyses;To couple, upper and lower sealing force is equal to draw guide post component center as optimization aim, is and full-tubular
The facade center of submersible pump coincides as optimal, arranges in the certain area of the first quartile at this center.
One embodiment of the present of invention has been described in detail above, but the content is only the preferable enforcement of the present invention
Example, it is impossible to be considered as the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng, all should still belong to the present invention patent covering scope within.
