Recently, the "high-pump-type variable-frequency energy-saving control cabinet for pumping unit" independently researched and developed by Hekang inverter successfully passed the examination and selection by the Ministry of Science and Technology and was successfully listed in the "2014 State Key New Product Plan" project. The honor of the acquisition highlights Hekkap frequency in the field pumping unit industry's leading edge technology and good prospects for the future. The state key new product plan is a plan jointly promoted and implemented by the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce and the General Administration of Quality Supervision, Inspection and Quarantine to promote independent innovation of enterprises and speed up the transformation and industrialization of scientific and technological achievements. It is also a national science and technology planning system important parts of. He Kang variable frequency pump-type pump-specific variable frequency energy-saving energy-saving control cabinet, the industry's leading PWM controllable rectifier technology, regenerative energy can be automatically fed back to the grid, the network side harmonic small, can achieve true four-quadrant operation, effectively solve In the process of oil production, the starting current is large, the energy loss is high, and the quality of the power grid is greatly affected, thereby helping the pumping unit users to reduce costs and energy consumption and improve the safety and system efficiency of the oil recovery system. At present, the product has entered the mass production stage, stable operation of the site in Hainan Oilfield, Shengli Oilfield, Yanchang Oilfield, Huabei Oilfield, the comprehensive energy-saving rate of about 20%. The implementation of the key new product planning project will further enhance the capability of independent innovation of Hekang Frequency Converters and promote the users of oil pumping units to conduct environmental protection, energy saving and efficient oil recovery. He Kang frequency will also take this as an opportunity to continuously develop new products, new technologies, new processes for China's oilfield industry, science and technology innovation and industrial upgrading to make more contributions!
