Foreword The IPC frequency changer designs by Albert Oilfield Design Institute of Canada, American Smart Chip Company produces. The Chinese market was secondary developed and promoted by Shenzhen Canon Electronics Co., Ltd.
The new IPC MD series oilfield feedback inverter integrated machine is completely based on the perspective of oilfield users and the newly developed oilfield-specific frequency converter adapted to oilfield production. Its strong military characteristics, protection functions and simple operation are the preferred products for oil field production. Currently, it has been widely used in large domestic oilfields such as Shengli Oilfield, Karamay Oilfield, Changqing Oilfield, Jianghan Oilfield, and Liaohe Oilfield.
Application Background Traditional pumping units generally suffer from many problems such as large starting shocks, high operating power consumption, and low efficiency. In addition, the oil wells are complicated, and there are many phenomena such as heavy oil, wax deposition, and Shaka. When it happens, there is no reliable protection function for the motor and the equipment maintenance volume is large. Installing IPC-DM series oilfield feedback inverter integrated machine can obviously save energy and improve efficiency, and it has a certain protection effect on the pumping unit.
System Features IPC-MD All-in-One is specially made for on-site oil refiners. The operation is extremely simple, changing the complex product concept that commercial inverters can use only for experts. With two-step speed adjustment, no complicated settings are required, no manuals are required, and the program is fully simplified. No errors will occur due to operation. For automation companies, it is a rare product with the lowest cost of use.
IPC-MD is designed and manufactured by Albert Oilfield Design Institute of Canada and Smart Chip Company of the United States according to the special working conditions of oil field pumping units. Since 1995, it has been used extensively in the Texas and Alaska oil fields.
CPU: Military 32bit DSP is used, and it can work normally at -40°C～+90°C. Reliability is much higher than commercial inverters.
Pumper-specific applications. The design is simplified. It is suitable for ordinary oil diggers to directly debug. There is no need for manuals and operation manuals. General commercial frequency converters will not have the concerns of ordinary workers because of many parameters.
All the up and down stroke settings are concentrated on the two potentiometers, only with the site map, through the potentiometer set the best curve. Or directly through the Chinese digital operator.
Chong times adjustable, 30% to 120%.
Built-in input filter device, full noise filter, interference to the power grid is 1/4 of common commercial inverter.
The built-in feedback braking unit can regenerate the regenerative power to the power grid. Because the reactor and noise filter have been configured, they can be directly connected to the 380V/660V power grid. The efficiency of the energy feedback grid is 97%.
The system has low reactive power loss and the power factor COS∮>0.96. The same power supply line can be properly loaded to save the capacity increase fee.
Flexible start-up, reducing the load impact of the grid, no impact on the motor and equipment.
The energy recovery part is more energy-efficient than ordinary commercial frequency converters by 15-25%. Heat loss is less than 3% of resistive braking.
Full automatic voltage tracking, automatic calculation of optimal braking torque, users do not have to set any parameters. Simplify the operation of the application link.
In compliance with the maintenance-free design concept, frequency conversion and feedback braking are integrated, allowing independent operation without external equipment. The failure rate is much lower than the combined use of common commercial inverters and feedback braking units.
Unattended in the field, fully automatic design, no need to change the mechanical equipment can be arbitrarily controlled pumping speed. Applicable to oil wells in different regions and structures. Suitable for different climatic and environmental conditions.
