Reserch on Multilevel Sections Synchronous Expanding and Contracting Hydraulics Cylinder

Multi level sections synchronous expanding and contracting hydraulics cylinder is a new type multilevel sections hydraulics cylinder, it has many special properties. Comparing with other general type multilevel sections hydraulics cylinder, it could achieve the synchronous actions of the multilevel sections hydraulics cylinder. Therefore, its transmission rate is high. Also it can maintain a steady speed when it works. It has a little impact and libration and works steadily. With accurately using, it could improve the properties of hydraulic system and efficacy of hydraulic equipment, and its value should be popularized. The basal structure and the principle of four sections synchronous expanding and contracting hydraulics cylinder are detailedly discussed in the article. The primary parameters about hydraulics cylinder, such as pressure and speed etc, are analyzed. The author also concludes the primary properties of the four sections synchronous expanding and contracting hydraulics cylinder in this article, and introduces a new type of multilevel sections synchronous expanding and contracting hydraulics cylinder.
