Product Description

The development of oil mining technology driven by submersible motor, Daqing Oil Field Co sixth oil production plant No. 1 oil mine! Daqing 163000, Heilongjiang, with the development of economy, people's living standards are increasing, and the demand for energy is increasing. How to improve the quality of oil recovery and reduce power loss is a major research topic in China's oil production enterprises. Since the introduction of submersible pump technology in China since 1981, it has been in the history of 30 years. The submersible pump, as an important mechanical oil production equipment, has been widely used in various major oil fields, and has become one of the important means of high production and stable production in oil fields.

At present, oil extraction technologies widely used in major oilfields at home and abroad include submersible pumps, submersible screw pumps, water conservancy piston pumps and gas lift. The electric submersible pump has many advantages, such as large pressure difference, strong adaptability, long service life, simple operation process, convenient management and so on.

It has made great contribution to the oil production technology of our country. With the innovation of oil field mining technology, using the electric submersible pump to improve the production of oil field has become the inevitable trend of the oil production in our country, and a complete oil production system has been formed gradually.

The submersible motor is a three phase squirrel cage Asynchronous Motor. When 50HZ, the rated revolution is 2850 rpm.

The oil submersible motor is a vertical suspension structure, which is filled with oil immersed closed type, filled with special lubricating oil of the submersible motor, and plays the role of lubrication, insulation and conduction of heat. The
Due to the limitation of different caliper diameters, various series and specifications have been designed to meet the needs of different oil wells. According to the different power requirements, the submersible motor can be single or double or multi section. The

Our company can produce 375 series, 456 series, 540 series, 562 series of submersible motor, and can produce the submersible motor with temperature 90, 120, 150 C according to the user's request.

At the same time, other products of our company include normal pressure injection water pump, supercharged water injection pump, single and double screw pump, reciprocating plunger pump, submersible pump unit and so on.
