Description

The invention relates to the field of pumping units or pumps, in particular to hermetic pumping units operating with high pressures at the pump inlet.
A horizontal pumping unit is known, comprising a support frame, an inlet pipe, an electric motor, an input module and a sectional centrifugal pump located on one shaft, the first section of which is aligned with the input module, and the last with the output pipe. Perpendicular to the input module case, an inlet pipe is installed. A thrust unit is located in the input module assembly (RF patent No. 2162163, class F04D 13/06, 1999).
The disadvantages of this design is the high complexity of manufacturing and limiting the pressure of the pumped liquid entering the installation.
The proposed design allows you to apply pressure to the inlet of the pumping unit in the range from the minimum, ensuring operation without interruption of supply, to the maximum, limited only by the mechanical strength of the component parts of the installation.
The specified technical result is achieved in that in a sealed pump installation containing a support frame, an inlet pipe, an electric motor, an input module and a sectional centrifugal pump located on one shaft, the first section of which is combined with the input module, and the last with the output pipe, according to the utility model , a submersible electric motor equipped with hydroprotection was used as a drive, while a submersible electric motor (SEM), hydroprotection (GZ) and the input module (VM) are placed inside a sealed horizontal columns
the end surface of which on the motor side is in communication with the inlet pipe for supplying the pumped liquid.
Thanks to the use of a submersible oil-filled electric motor with hydraulic protection, the pressure inside the column and inside the electric motor is balanced by the diaphragm of the hydraulic protection, as a result of which the differential pressure does not act on the shaft seals located between the VM and the main compressor, which allows sealing the shafts at high inlet pressure.
In the claimed design can be used PEM, GZ, cable and BM similar to that used in submersible pumping plants, which makes the installation technological in manufacture.
The invention is illustrated in the drawing, where in FIG. presents a diagram of the proposed sealed pump installation.
The proposed pump installation is mounted on a support frame 1 and contains sequentially mounted on the shaft PED 3 with GZ 4, VM 5 and a multi-section pump 6. PED 3 with GZ 4, VM 5 are coaxially placed in a horizontal column 2 on centralizers 13. Input module 5, made in the form of a sleeve with side openings, connected to the pump 6 through the front adapter flange 10 of the horizontal column 2. A cable 7 is tightly connected to the submersible motor 3, having a cable seal assembly 8. in the area of the passage through the front adapter flange 10. The column 2 has an inlet flange 9 connected to an inlet pipe 11 for supplying a pumped liquid.
Hermetic pumping unit operates as follows.
Power supply of the PED 3 is carried out via cable 7. The pumped liquid with the input parameters enters the pumping unit through the inlet pipe 11 and moves inside the column 2 along the path 14 along the PED 3 with GZ 4 and is fed into the pumping unit 5
pump 6. The pressure of the liquid (oil) inside the PEM and the gas cylinder is balanced with the inlet pressure on the principle of communicating vessels using the gas diaphragm. Therefore, the elements of the PED and GZ are not affected by the load from the liquid pressure. In fact, the only place on which the differential from the inlet pressure acts is the cable seal assembly. Therefore, the inlet pressure is limited by the strength of the column 2 and the cable seal assembly 8. When passing through the pump 6, the kinetic energy of the fluid flow acquires the necessary pressure increase and is output through the outlet pipe 12.
Thus, the proposed design solves the problem of sealing the rotating shafts of the pumping units.
