Description

The proposed utility model relates to the field of pumping plants designed for injection under high pressure fluid, which can be used for various consumer needs, for example, to maintain reservoir pressure (RPM).
A horizontal booster pumping unit (RF patent No. 2380577, IPC F04D 13/06, F04D 9/04, 2010) is known in the prior art, comprising a support frame, an electric motor, auxiliary and main centrifugal pumps, a discharge unit and suction units located on the same shaft. at the entrance to each pump, while the auxiliary pump is connected to the electric motor, the discharge unit of the auxiliary pump is combined with the suction unit of the main pump, and the capacity of the main pump is significantly higher than the auxiliary.
The disadvantages of this design are the significant overall dimensions of the installation along the length and high metal consumption of the frame.
Closest to the technical nature of the proposed installation is a vertical centrifugal pump installation, containing an electric motor, a pump sandwiched between two flanges, located inside the column and attached to its base, having inlet and outlet channels, an outlet for air outlet in the column cover, a motor shaft connection unit and a pump located inside a conical spacer, the lower flange of which is joined to the column cover, and an electric motor is installed on the upper flange (EP 0907029 A2, F04D 29/40, 1998). The shafts of the electric motor and pump are connected using a detachable coupling, the pump is fixed to the base with a bolt screwed into the shaft.
The disadvantage of this installation is the restriction of the pressure of the pumped liquid entering the installation.
The objective of the utility model is to ensure the operability of the installation at high inlet pressure by increasing the tightness.
The specified technical result is achieved by the fact that in a vertical centrifugal pump installation containing an electric motor, a centrifugal pump fixed in the base having inlet and outlet channels, a column covering the pump, a spacer with upper and lower flanges, inside of which there is an assembly for connecting the motor and pump shafts , and the air outlet, according to a utility model, the shafts of the electric motor and pump are connected by means of a magnetic coupling, a magnetic separator is additionally installed in the upper part of the column, and the pump housing is screwed into the base.
To adjust the radial position of the motor, the upper flange of the spacer is equipped with stops.
In addition, the exhaust outlet can be made in the form of a radial channel inside the lower spacer flange.
In FIG. shows a General view of the inventive installation in the context.
The vertical pump installation includes an electric motor 1, a cylindrical spacer 2 with upper 3 and lower 4 flanges, a centrifugal pump 5, coaxially placed inside the column 6, and a base 7 having an input 8 and output 9 channels. The electric motor 1 is mounted on the upper flange 3 and aligned with the centrifugal pump 5 by means of adjusting screws 10 installed in the stops 11. Inside the vertically oriented spacer 2 there is a magnetic coupling 12 connecting the shaft of the electric motor 1 to the shaft of the pump 5.
The magnetic coupling 12 is supported on the lower flange 4 of the spacer 2, in which there is a radial channel 13 for the exit of air displaced by the fluid entering the pump 5, and a fitting 14 for connecting the valve 15. The flange 4 is joined to the flange 16, which is mounted on the column 6. Behind the magnetic coupling 12 in the upper part of the column 6 there is a magnetic separator 17, which is centered on the pump 5 and the flange 4. The pump 5 is fixed in the base 7 with a threaded end made, for example, on the adapter 18. Thanks to the threaded connection of the pump 5 with the base 7 d the alignment of the pump 5 in the column 6 is achieved, which ensures alignment of the shaft of the pump 5 with the shaft of the motor 1 and increases the reliability and durability of the installation.
Installation of the proposed vertical pump centrifugal installation is as follows.
The pump 5 with the adapter 18 connected to it is twisted into the base 7; then a column 6 with an upper flange 16 is hermetically installed in the base 7; a magnetic separator 17 is mounted on the pump casing 5; after which a spacer 2 with a lower flange 4 is fixed on the flange 16. Next, a magnetic coupling 12 is mounted on the pump shaft 5, an electric motor 1 is placed on the upper flange 3 of the spacer 5 and centered using the adjusting screws 10. Thanks to centering, the likelihood of jamming of the pump shaft is reduced and increases durability of the installation.
Vertical pumping unit operates as follows.
When you turn on the motor 1, mounted on the flange 3, the rotation is transmitted to the pump shaft 5 through a magnetic coupling 12, protected by a magnetic separator 17 from the ingress of metal inclusions. The pumped liquid with an inlet pressure of up to 20 MPa is fed through the supply pipe through the inlet channel 8 of the base 7 to the column 6, where it rises along the annular gap and enters the pump 5 from above. The air from the column 6, displaced by the rising liquid, is discharged from the installation through the channel 13 through the fitting 14. Then the valve 15 is translated into the closed position. The liquid which has entered the pump 5 is pumped back under pressure into the base 7 and, through the outlet channel 9, enters the discharge pipe and enters the consumer.
Thus, the proposed design is more technologically advanced, since the magnetic coupling provides a high degree of tightness of the pump without the use of additional sealing means, which ensures high inlet pressures and also prevents breakage of the motor shaft in case of jamming of the pump shaft.
The installation is easy to assemble due to the threaded connection of the pump with the base, which provides centering of the pump in the column.
The proposed installation is industrially applicable, since standard structural elements are used for its implementation.
