目前,国内稀油循环润滑系统敷设于机器上的支管常采用图1的形式。每根支管上装有1/2英寸截止阀及1/2英寸油流指示器各一只,以便控制各供油点油量。例如,复二重式线材轧机精轧机列五台联合减速机的供油点就有74处之多。也即需用74根这样的供油支管。整个系
Currently, the domestic thin oil circulation lubrication system laid on the machine branch pipe often use Figure 1 form. Each branch is equipped with a 1/2 inch globe valve and a 1/2-inch oil flow indicator each in order to control the amount of oil supply point. For example, complex dual-wire mill finishing mill five joint reducer fuel there are as many as 74 points. That is required to use such a 74 oil supply branch. The whole department
