Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figs. 1-2, the present embodiment provides a kind of peak regulation energy-saving pumps, including：Motor 1, bracket 3, water pump outer cylinder 6, pump
Axis 12, baffle.
The upper end of the lower end connecting bracket 3 of motor 1, and shaft coupling 11 is connected at its lower end center, shaft coupling 11 is set to branch
The inside of frame 3.
Bracket 3 is the fixation device with 10 structure of water outlet, and lower end connects the upper end of water pump outer cylinder 6.Water pump outer cylinder 6
For hollow cylindrical structure, middle and upper part is equipped with water inlet 5, and water inlet 5 and water outlet 10 together form in one into upper
Structure out.Water inlet 5 is set to the middle and upper part of water pump outer cylinder 6, high water outlet pump bottom surface certain distance, so that peak regulation energy-saving pump is stopping
A certain amount of water can be retained under machine state, which is enough to flood at least one impeller 13.After peak regulation energy-saving pump is again started up, quilt
The impeller 13 flooded drives water rotation to move from bottom to top, while generating negative pressure in suction side, and water is by sucking peak regulation energy conservation successively
In pump, the intake performance of peak regulation energy-saving pump is improved, reduces the risk of cavitation erosion；On the other hand, water constantly moves upwards,
Gas extrusion discharge inside peak regulation energy conservation pump housing, it is therefore prevented that mechanical seal 2 works in anhydrous situation and dry grinded
Phenomenon extends the service life of peak regulation energy-saving pump.In addition, water outlet 10 can arbitrarily be rotated relative to circumferential 360 ° of water inlet 5, it can
Meet the plumbing requirement of different designs angle, it is easy for installation.
The inside of water pump outer cylinder 6 is equipped with support frame 16, baffle, pump shaft 12, and lower end connects pedestal 9.
Baffle is set on pump shaft 12, is internally provided with impeller 13.Impeller 13 is rotated by the drive of pump shaft 12, will be moved
Water supply can be transmitted, baffle then converts potential energy for the kinetic energy of water, and imports next stage impeller 13.Baffle includes chopped-off head water conservancy diversion
Body 7, submerged bearing baffle 15, multiple second level baffles 14, and support frame 16, chopped-off head baffle 7, submerged bearing baffle 15, two
Grade baffle 14 sets gradually to form centrifugal multistage pump multiple centrifugal pump from the bottom up.
The upper end of pump shaft 12 connects shaft coupling 11, and lower end connects support frame 16.Motor 1 is by shaft coupling 11 torque from electricity
Pump shaft 12 is passed on arbor, makes pump shaft can the rotation of impeller 13.And mechanical seal 2 is provided between pump shaft 12 and bracket 3,
To guarantee 6 internal pressure of water pump outer cylinder.
It is provided with O-ring 17 between water pump outer cylinder 6 and bracket 3 and pedestal 9, ensure that the good sealing of peak regulation energy-saving pump
Property.It is additionally provided with pull rod 4 between bracket 3 and the pedestal 9 to be fixed, increases the stability of peak regulation energy-saving pump.
The junction of submerged bearing baffle 15 and pump shaft 12 is additionally provided with guide bearing 8, is made, avoids of wear-resistant material
Direct friction between submerged bearing baffle 15 and pump shaft 12 reduces damage.
The specific workflow of the present embodiment is：Torque is passed to pump by shaft coupling 11 by motor 1 from the axis of motor 1
Axis 12, the rotation of 12 impeller of pump shaft, the impeller of rotation transfer kinetic energy to water.Water is entered by the water inlet 5 of water pump outer cylinder 6
It after first order impeller obtains kinetic energy, is spread in chopped-off head baffle 7, part kinetic energy is become potential energy, the potential energy of water increases.Potential energy
Water after increase, which enters in submerged bearing baffle 15, to spread, and continues to transfer kinetic energy to water by second level impeller, the potential energy of water into
One step increases, pressure rise.Water successively passes through multiple second level baffles with identical supercharging mode later, finally by topmost
Second level baffle 14 through on bracket 3 water outlet 10 enter user's pipe network.
Into upper structure out in a kind of peak regulation energy-saving pump of the design, ensure that under shutdown status, peak regulation energy-saving pump
Inside can retain a certain amount of water, which is enough to flood at least one impeller.After peak regulation energy-saving pump is again started up, it is submerged
Impeller drives water that its internal air is discharged, and not only prevents mechanical seal and works in anhydrous situation and dry grinding occur now
As；The intake performance of peak regulation energy-saving pump is also improved, the risk of cavitation erosion is reduced, extends the service life of mechanical seal.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
