临颖喷灌机厂经过几年努力,研制成功了摇臂式喷头弹珠摆块式换向器,经过二年来的田间考核,并经水利部农田灌溉研究所性能测试,证明性能良好,使用可靠,现简介如下: 结构与工作原理 1.弹珠摆块式换向器主要有摆块、压缩弹簧、滚珠、拨杆、换向器座组成(图1)。全部零件联结在换向器座上,由两个 After several years of efforts, Linying Spray Irrigation Machine Factory has successfully developed a rocker arm type pendulum pendulum block commutator. After two years of field assessment and performance tests by the Institute of Irrigation and Farmland Irrigation, it proved that the performance is good and reliable Now the brief introduction is as follows: Structure and working principle 1. The pendulum pendulum block commutator mainly consists of a pendulum block, a compression spring, a ball, a lever and a commutator block (Figure 1). All parts connected to the commutator seat, by two
