浅析液电效应原理及应用

文章介绍了液电现象的基本概念,阐述了液电效应原理,液电效应装置及基于其声学、力学、生化效应及在各领域的应用。分别对液电效应应用于液电加工、液电清洗、臭氧处理废水、体外碎石、水下目标探测等进行分析,综述了液电效应在国内外的研究现状及发展趋势,指出提高电源的储能密度,研制大功率的转换开关和产生高重复频率的大功率脉冲是该技术最主要的发展方向。

井口安全控制系统自控部分现状分析及优化

井口安全控制系统的稳定可靠是油田气井安全生产的保障。现场应用表明,基于电-液工作原理的井口安全控制系统故障多源于自控部分,为了从本质上提高系统的可靠性,需对现有系统的自控部分进行分析和优化。分析了塔里木油田井口安全控制系统的工作原理及特点;针对系统自控部分现状,从自动化架构、安装接线、运行环境等因素,指出了系统自控部分现存的问题;提出了自控部分优化方案和整改建议。控制柜应进行通风散热、减振等设计,采用改进型高度集成化的自动化架构(冗余控制器)等研究结果可为油田高压油气井井口安全控制系统优化改造和后续采购提供参考依据。

Theoretical analysis of output speed of multi-pump and multi-motor driving system

A theory for multi-pump and multi-motor hydraulic systems is presented in this paper based on the analysis of the advantages and disadvantages of the popular hydraulic transmission and the double-stator motor(pump).By taking the single-acting fixed displacement multi-pump and multi-motor driving system as an example,the output speeds in a variety of connections of this novel hydraulic transmission are analyzed theoretically.This research work lays a theoretical foundation for the study of the multi-pump and multi-motor driving system and for the design of the system principle diagram.
