柴油机不喷油故障的检查顺序

作者:康明斯发电机厂家 发布日期:2016-08-27 来源:www.0755fdjz.com 点击:

 我们在使用柴油机时难免会遇到一些故障,下面我们就来简单介绍一下柴油机不喷油故障的检查顺序,

第一步,查看油箱中是否有油,油是否凝结,油箱开关是否打开,调速手柄是否放在中间位置。
第二步,摇车观察高压油管及两端接头处是否漏油。
第三步,拧开喷油泵的放气螺钉,放尽空气,如果不流油或流油不畅,表明低压油路堵塞。
第四步,卸下高压油管,如果有油从出油阀紧帽孔中流油出或滴出,说明出油阀漏油。
第五步,摇车看有无油一股股地从出油阀紧帽孔中喷出。无油喷出表明喷油泵处于不喷油的位置,可能是油泵柱塞或调速器有犯卡的地方,也有可能是连接脱落。油泵柱塞转到最大供油位置仍不喷油,可能是油泵弹簧折断或柱塞卡死在柱塞套中,弹簧不能使柱塞回位。
第六步,摇车有油一股股地喷出,接上高压油管和喷油器就无油喷出,说明油泵柱塞严重磨损,或喷油嘴烧死在关闭位置,也可能是喷油压力调得过高 。
