By using the D71 frequency converter, the motion law of the pumping unit can be adapted to the changing working conditions of the oil well, so as to improve the system efficiency and achieve the
Abstract The invention discloses a kowtow type associated gas pumping unit. A swing cylinder of a swing cylinder temperature difference engine is used for replacing a walking beam of an electric
This study optimizes the tilt angle of photovoltaic (PV) panels on a large oil tanker ship system and considers the impact of partial shading to improve the performance of the PV system.
Considering the shortcomings of beam pumping unit, a kind of mainstream equipment serving in oilfields of China today, also known as "Kowtow Machine", such as high energy
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the
Flywheel energy storage systems store kinetic energy in rotating mass to deliver rapid response, improve grid stability, and support renewable integration with high efficiency, reliability, long cycle life,
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system.
The utility model adopts the technical scheme as follows: an energy-saving device of a kowtow machine of an oil and gas field comprises a processor, a storage battery, a battery heater,...
Kinetic Energy Storage Systems (KESS) are based on an electrical machine joined to a Flywheel. When the system stores energy, the electrical machine works as a motor and the flywheel is accelerated
