Pavilion: W2, booth no. : W2366.

Shandong yanshan pump industry co., LTD., as the leading enterprise of China's electric submersible pump system, began to produce the submersible electric pump in 1985, and the parameters of the products meet the performance requirements of American radar company and ODI company. February 2012 successfully developed servo direct drive submersible screw pump, the system has greatly improved, compared with foreign companies by the ground frequency vector control system, the underground cable, screw pump, protector, and motor, etc. Motor with a very low speed servo permanent magnet motor, remove the intermediate transmission reducer, solves the problem of low reliability, at the same time improve the efficiency of the system, product performance to reach the world advanced level. The servo direct drive oil screw pump has been used in daqing oilfield and shengli oilfield, receiving good oil recovery effect. Shandong YanShan servo submersible motor pump industry production, submersible screw pump system, which is dedicated to under complex conditions, such as fluid viscosity is not more than 8000 CPS, heavy oil emulsification well, high solid content, unstable flow, low production, such as the excessive hydraulic fracturing, servo direct drive submersible screw pump has better performance. In addition, the use of servo direct drive oil screw pump is easier to debug. Under certain conditions, the servo direct drive submersible screw pump can replace the pumping system perfectly. The servo submersible motor is different from the conventional electromagnetic induction motor, and the design of the servo submersible motor integrates the permanent magnet. The sintered rare earth permanent magnet requires little power to generate rotor flux. As a result, the power rating requirement phase at the same time, compared with the traditional induction motor, servo permanent magnet submersible motor, have a higher starting torque, is the traditional induction motor 2-3 times, improve system efficiency and reduce the power loss, lower system current and heat unit. Due to the low heat production, the cooling demand of servo submersible motor is lower than that of conventional motor, and can be operated at lower frequency. The servo submersible motor USES variable frequency vector control, so that the system can adjust the well condition change timely, optimize or eliminate the adverse effect of low velocity condition, thus ensuring maximum output. Therefore, the advantage of low yield heat, fast and superfine control makes the operation range of servo submersible motor increase. The permanent magnet motor USES the powerful rare earth magnet embedded inside, so that the motor can operate synchronously with the changing speed of the motor magnetic field. On the structure of servo submersible motor has higher power density than the induction motor, at the same time, the unit starts up, through the vector control of stator current and torque current, the servo system of submersible motor can output 2 ~ 3 times higher than the induction motor's starting torque, greatly improving the system of complex well type of reliable and economical operation. The servo direct drive oil screw pump avoids premature wear of sucker rod/tubing caused by the conventional sucker rod drive system due to the limitation of depth or deflecting well. And the traditional electric submersible screw pump system usually USES the traditional submersible motor to fit the oil screw pump system of the reducer, and its rotating speed is between 100-500. YanShan pump industry manufacturing servo direct drive submersible screw pump has similar configuration with submersible screw pump, the main difference is the system without the use of the reducer, the 10 servo permanent magnet motor, screw pump by inverter vector control servo submersible motor pump speed between 50-350 speed operation system without using reducer, improve the reliability of the system. In addition, compared with the conventional submersible motor, servo system of submersible motor has higher power efficiency compared with the traditional way of artificial lift, servo direct drive submersible screw pump is significantly improved the slope, the efficiency of heavy oil emulsification Wells and horizontal Wells. Compared with other schemes, the operation efficiency of the servo direct drive oil screw pump is significantly improved compared with other schemes for the slope part of the well and the horizontal section of the operation. The system has all the advantages of screw pump system, and there is no risk of wear of rod. It can be said that the system is the ideal form of servo direct drive oil screw pump, which will be better than the surface wear caused by environmental impact. As the system reduces the wear of sucker rod or pipe, the number of related workover and the cost are greatly reduced. The example proves that the service life of the servo direct drive submersible screw pump system is long, and the average can reduce 2~3 workover operations, which can save the customers thousands of manual intervention costs. Imagine a screw pump system with no lever and no speed reducer to understand the wonders of the servo direct drive submersible screw pump system.
