Regarding the elevation marks on the equipment drawings
Thread Content
When I was looking at the blueprints today, I came across one that included elevations. What’s the use of elevations for equipment? Aren’t the equipment dimensions sufficient?
Elevation refers to the altitude or height level; it’s essential to have this information. The factory area needs to be drained, and there is a relative height between various equipment, so elevation is definitely necessary.
Basically agree; what needs to be discussed is that elevation does not necessarily refer to altitude. It is generally the relative elevation between devices; each construction entity has its own zero point.
Elevations are still very useful, especially during on-site installation; many devices come with indicated elevations. Without these elevations, installation becomes difficult
Compared to the entire factory, a machine is just a small component; the elevation serves to indicate its installation location relative to the height of other machines or facilities. Manufacturing a machine in isolation isn’t very useful, but when it comes to installing it on-site, elevation information is essential.
The elevations indicated on the drawings help designers take into account the negative effects of height on the equipment, thereby enabling structural improvements, and assist installers in determining the installation methods and tools (such as cranes)
The design elevation refers to the installation position of the equipment, indicating the relative positional relationship between the equipment and other facilities
The equipment elevation refers to the installation height of the equipment relative to the zero level of the device in which it is located.
The equipment elevation is a crucial dimension for large-scale equipment. It is generally the relative elevation with respect to the workshop floor, meaning the workshop floor is set at zero. 1. For example, in a silicon electric furnace device that has working layers at various heights, it is necessary to construct multiple floors, such as a charging layer, an electrode insertion layer, a furnace ramming layer, a silicon extraction layer, and so on. Moreover, requirements for the relative height of electrode layers are quite precise; otherwise, issues such as arc distance will arise. 2. The elevation on the overhead crane is also a key issue. Whether the highest point of the crane collides with the factory roof beams, the elevation marks for the hook’s upper and lower positions, the elevation of the tracks, etc. This post was last edited by shifeng18 on 2009-3-3 09:55]
