Advantages of the HPS:
- High efficiency and optimization of
parameters of expenses for 1m³ of Flow.
- Flexibility of system during disassembling
or installation of pump section.
- HPS are convenient in service and repair.
- The opportunity of use both for group
injection, and for individual injection in oil wells.
.
Equipment:
1. The three-phase asynchronous electric
motor provides a drive of the pump. Rated voltage is:
0,38, 0,69, 6 kV.
A temperature mode of operation is up to
Rotation frequency of a shaft of the electric motor is 3 000 RPM
(rotates per minute).
2. The thrust chamber is intended for removal
of axial loadings and anti-pressure removal from pump section.
3. The corrosion resistant
horizontal centrifugal pump is intended for pumping injected liquid.
Recommended pressure upon input of the pump from 0,5 up to 4,0 МПа. Frequency of rotation of a shaft of the pump – 3000-4106 RPM. Efficiency
of the pump is 72 %.
4. The assembly frame is intended for installation HPS parts on it.
5. The frequency converter
provides safe smooth start-up and stop
of the pump unit, protects the engine from high current loadings, allows to
abandon an opportunity of sharp shock mechanical loadings on a shaft and the
thrust chamber of the pump occur, smooths lacks of network power supplies of
technological installations.
Besides this application of the frequency converter provides essential
reduction in expenses for the electric power, especially at operation together
with system of PID-regulation.
6 . Control system on the
basis of the controller includes the frequency converter and system of
PID-regulation (PID means automatic maintenance of the set pressure on output
the pump due to correction of frequency).
With its help it is possible to maintain work of pump systems
in a zone of the maximal efficiency (so minimal energy consumption),
owing to that that the system itself selects necessary frequency of rotation of
the engine of pump system for maintenance of the set pressure on an output of
the pump.
And, with change of injection
conditions :
- Changes of amount and
pressure of water on the input of the pump;
- Changes intake
capacity of well;
- Change of the pump
ratio.
Automatics will control
the set pressure on an output of the system.
It is necessary to note,
that the frequency converter self-setups on loading in such a manner that the
optimum balance of consumption of active and jet power is provided.
Control system is
equipped with the controller, allowing to bring parameters of work of the HPS
in memory and to transfer the data through RS-485 interface.
