大型工程机械的高负载摩擦部位,一般采用润滑脂供给系统进行润滑。该系统的主要部件为喷射阀,喷射阀在压缩气体的带动下将润滑脂均匀喷射到润滑部位,可使润滑脂分布更为均匀,润滑效果更佳。本文在介绍喷射阀工作原理的基础上,讲述其故障排查方法。1.工作原理喷射阀由喷射阀阀体1、柱塞2、弹簧(3、7)、密封垫4、钢球5、钢球座6、锁紧螺母(8、12)、弹簧座9、单向阀阀体10、喷嘴11、保
Large-scale construction machinery, high-load friction parts, the general use of grease supply system for lubrication. The main component of the system is the injection valve. The injection valve injects the grease evenly into the lubrication area under the driving of the compressed gas, which can make the distribution of the grease more uniform and the lubrication effect is better. This article describes the working principle of the injection valve, based on the troubleshooting method. 1. Working principle The injection valve consists of the injection valve body 1, the plunger 2, the spring (3,7), the seal 4, the steel ball 5, the ball seat 6, the lock nut (8,12), the spring seat 9, Check valve body 10, nozzle 11, Paul
