A few days ago, I had the pleasure of reading the light of science, Shadow of Art-liu he's collection of photography works. 

    The book's title, “The light of science, the shadow of Art-liu he's collection of photographs”, actually reflects the two main themes of the book, “The light of science” and“The shadow of Art”, the former includes Liu he and pumping unit-related photographic works, the latter is the summer palace landscape photos taken by the author. In this issue, I would like to share with you the chapter“The light of Science”. The author Liu he is an oil exploitation worker. He has been in the oil field and dealing with pumping units for many years. The pumping unit meant something to him. It was a subject of study, a work partner and a friend of the Inseparable. When it comes to pumping units, which is also known as“Kowtow Machine”, is essential to the development of crude oil automation equipment. The pumping unit supported by the linear motor is one of the main pumping units, which makes use of the linear reciprocating motion of the linear motor to drive the sucker 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 Mau Electronics Co. , Ltd. develops, manufactures and sells its own linear motors, which include iron-cored linear motors and iron-cored linear motors. Both adopt European and n technical standards and processing techniques, with high speed, high precision, high frequency response, long life and so on.
