Horizontal pumping units
RINPO LLC, a subsidiary of Sistema-Service Group of Companies, produces horizontal pumping units, makes repairing, testing, and maintenance of HPU.
Details
Horizontal pumping units
Purpose
Designed for injection of fresh, reservoir, and waste water into oil reservoirs in order to maintain reservoir pressure.Application
Capital and module cluster pumping stations of reservoir pressure maintenance systems in oil fields.Work principle
HPU is a power machine which converts mechanical energy into hydraulic energy of the pumped liquid. The injection unit is attached to the flange of the suction chamber, through which the liquid is pumped.Construction
Electric motor – to create torque; serves as a pump motor.Intensifier – to increase the pump shaft speed and distribute torque between the pump sections when they work simultaneously.
Thrust chamber – for axial relief of the pumping unit from the pressure of the pumped liquid.
ESP centrifugal pump – a power machine which converts mechanical energy into hydraulic energy of the pumped liquid. The injection unit is attached to the flange of the thrust chamber, through which the liquid is pumped.
Advantages
Cooling system – prevents heating and premature wear of bearing joints of the thrust chamber and intensifier. Frame – made as a base on which there are places for attaching the components of the HPU and the protective-enclosing casings of the collars.Requirements for the composition of the pumped liquid
• Mineralisation – no more than 249.7 oz/ft³;• Hydrogen index – 5.4-7.5 pH;
• Content of dissolved gases:
H2S – no more than 0.2697 oz/ft³;
CO2 – no more than 0.2997 oz/ft³;
Oil – no more than 0.1998 oz/ft³;
• Weight concentration of solids – up to 0.04994 oz/ft³ with a size up to 7 874 μin;
• Water density – from 0.9988 to 1.179 oz/ft³ with temperature from +41°F to +176°F.
HPU versions
Due to the lack of intensifiers supply, only single-section versions without a intensifier in the table are highlighted in red color. Horizontal pumping units (HPU) to provide the necessary required characteristics are made in several versions, each of which has different typical designs, differing in the number of stages in the section and the number of sections in the system.HPU types
• Single-section with a frequency converter (hereinafter referred to as the "FC,” which serves to expand the range of modes of operation and regulation of pressure-flow characteristics of HPU).The use of the frequency converter:
• Allows to regulate pressure-flow characteristics (due to frequency correction);
• Ensures smooth start and stop of the pumping unit;
• Protects the electric motor from current overloads;
• Allows to eliminate the possibility of sharp mechanical impact shock on the shaft and thrust chamber of the pump;
• Mitigates the shortcomings of the mains power supply of process units;
• Reduces energy costs by ensuring the operation of pumping units in the zone of maximum efficiency (due to the fact that the system itself selects the required speed of the electric motor of the pumping unit to provide a given outlet pressure).
