新型全状态调控式液压抽油机的研究

Introduction to a new type of all-state controlled hydraulic pumping unit

对当前我国抽油机现状及世界液压抽油机的发展方向作了评述与分析,着重介绍了全状态调控式(ASC)液压抽油机的总体框架、特点、关键技术和创新点。该机冲程和冲次可以连续调节;效率可提高50%以上;超载、断杆能自动停机报警并能解决偏磨问题,此外该机无配重块,平衡度可以达到或接近1;质量轻;寿命长;一般免修期为3～5a。文章将所涉及的研究成果分8部分在本刊陆续刊出。

The present situation of the pumping units in China and several developing directions all over the world are commented and analyzed. The overall framework, characteristics and key techniques of ASC hydraulic pumping units developed by the author are in focus. The stroke, frequency of stroke may be regulated continuously,the efficiency can raise to over 50% When the overload and rod breakage occur, this unit can alarm and stop automaticallyThe deviation grinding issue can be solved, in addition, no balance weight is needed, and the equilibrium ratio can reach or close to 1, the service time is long, and the repairfree period is 3～5 years. This article will be published in eight parts in the following issue.
