矿用提升机液压站变频控制系统设计
|
摘要
液压站是矿用提升机的一个重要部件,传统的液压系统在提升机运行过程中液压泵始终处于全速运行状态,需要以最大流量为系统供油,存在机械磨损严重、噪声大、能耗高等问题,处于一种不经济运行状态。为解决上述问题,本设计在保持现有液压站基本结构不变的基础上,采用PLC和变频控制技术对液压站的压力调节进行设计和改造,使其具备更高的安全性和更好的经济性。
A hydraulic station is an important part of a mine hoist,and in a traditional hydraulic system,a hydraulic pump operates at a full speed all the time in the hoisting operating process to supply oil to the system at the maximum flow and it involves such problems as serious mechanical wear,high noise,high energy consumption and uneconomical operation status. In order to solve the above problems,on the basis of maintaining the basic structure of the existing hydraulic stations,PLC and variable frequency control technology are adopted to design and renovate the pressure regulation of hydraulic stations to make them safer and more economical.
