As the saying goes, "you can't make bricks without Straw" , downhole tools play a vital role in the process of oil extraction, and their performance and quality are directly related to the safe nature and efficiency of oil extraction. 

    Recently, with the help of advanced 3D printing technology, the Engineering Institute of Northwest Branch has produced a 7-5/8 inch leakage control plate valve with blowout prevention and leakage prevention function to avoid well fluid leakage, injection and formation pollution, 6-5/8 inch leakage control ball valve and large diameter packer for sealing and isolating formation. It is reported that at present, the Engineering Institute of Northwest Branch is making great efforts to use 3D printing technology, and the downhole tools based on 3d printing technology have the advantages of visualization and flexibility. Speaking of 3D printing technology, its development and popularization can not be separated from the push of linear motor technology. Long ago, linear motor has many practical applications in Planar printing equipment. On the basis of this mature experience, a linear motor is introduced into a 3d printing device as a driver for related components. And the "origin" of the linear motor with the oil industry goes beyond this point. The linear motor is also used in modern hard core pumping units. This type of pumping unit directly uses the linear reciprocating motion of the linear motor to drive the pumping rod up and down, compared with the traditional pumping unit, it can save 20%-40% electricity when pumping the same amount of oil in the same time. 

      Kunshan Tong Mao Electronics Co. , Ltd. has been committed to the development, manufacture and sales of Linear Motors, linear motors with Mao made including no iron core U Slot and flat plate with iron core two categories, all adopted European and American technical standards and processing technology, exported to overseas.
