气门组包括进气门、排气门、气门弹簧、气门导管、弹簧做和气门半圆锁片等。1.进、进气门为提高进、排气量,N系列和K修理机的每个气缸装有4个气门(2个气门和2个排气门)。进、排气门均采用平顶式,气门锥角均为30°。气门有两种制作方法,一种是用金属制作的,另一种是在前面密封锥面上推焊有特种合金。为了提高排气门在高温下的耐热和耐腐蚀性,提高排气门的使用寿命,在排气门密封锥面上推焊有耐热合金。6个气缸的气门排列顺序,从前到后为-进-进-排-排-进-进-排-排-进-进-排。KTTA机进、排气门的位置气门导管压装在气缸盖上,在导管的上端面有较大的外倒角,以减少机油流入气缸的可能性。2.气门座气门座与气门头部共同对气缸起密封作用,并接受气门床来的热量。气门座用较好的材料制作,然后再气缸盖上。6BT型机气门座。KTTA型机气门座。为减少进气门的磨损,进气门座的接触带比排气门要宽些,在更换气门座时一定要辨认清楚,不要将进气门座安装到排气门座的位置上。动力设备(深圳)有限公司隶属于集团旗下固原干式变压器组业务中国区服务提供商,主要运营东风和两大品牌在中国的固原干式变压器组产品的出售租赁、维修保养及其售后服务。为军工企业、工厂矿业、商场超市、地产酒店、建筑施工、桥梁隧道、活动演出、娱乐会所演唱会供应紧急和长期后备应急电源,根据固原干式变压器组其功能区分为:移动式、固定式、超静音式、机组载式发电设备。常见功率(千瓦)范围:50KW,,150KW,200KW,250KW,300KW,400KW,500KW,800KW,1000KW等功率段。更多有关的最新产品和技术内容,请登录固原干式变压器官网首页:
