Who decides whether double nuts should be used on the skirt of non-standard equipment? Personally, I think it should be clearly specified by the equipment specialists, but the people in our unit’s equipment department say they can’t make that decision – what a mess! Who exactly should be in charge of this? ! ! Those who know, please reply~~
Also, it seems there are many different types of nuts; shouldn’t it be the equipment specialists who decide which standard nut to use?
First, we need to consider the purpose of using dual nuts. There are two reasons for installing dual nuts: 1. The nuts serve to provide a securing function. 2. It serves to prevent loosening. It is easy to understand from the function of the dual nuts; these nuts should be selected by mechanical designers based on the conditions specified by the manufacturing process. It should be designed by mechanical designers as needed. Those who propose the process conditions only need to specify the size and operating conditions of such custom equipment, as well as the location of its support points; it’s not necessary to go into details such as those related to dual nuts.
The standards for nuts are also determined by mechanical engineers, who select the appropriate standards based on the type of nut they choose.
In any case, the equipment specialty should confirm it. Since it is used for fixed equipment, its size and strength are determined by the equipment itself.
The equipment is designed by the engineering team, but the process engineering team must provide operating parameters such as vibration levels
