1 概述我厂研制的CDZ32登高平台消防车,其工作平台上设有卷扬救生机构、水炮射流调整、水炮仰俯角调整、水炮左右摆动调整和平台左右摆动机构。这些机构均需液压马达和液压缸来操纵控制,其中卷扬救生机构所用的液压马达需要高压大流量供油,而控制水炮及工作平台的液压缸则要求动作平稳、缓慢、微动性好,这就需要低压小流量供油。为了减少节流时的能量损失,提高效率,减少系统发热,我们设
1 Overview CDZ32 platform developed by our factory is equipped with a winch lifesaving mechanism, water jet adjustment, tilt angle adjustment of water cannons, swing adjustment around the water cannons and swinging mechanism around the platform. These agencies require hydraulic motors and hydraulic cylinders to control the operation. The hydraulic motors used in hoisting life-saving structures require high-pressure, high-flow oil supply. The hydraulic cylinders that control the water cannons and work platforms require smooth, slow and fine motions , Which requires low-pressure small flow of oil. In order to reduce the energy loss throttling, improve efficiency, reduce system heat, we set
