Are the sizes of the two impellers in a 70-cubic-meter PVC polymerization reactor different?

Generally, there are no drawings available for this; consult the equipment manufacturer or have it surveyed
Top part is larger and the bottom part is smaller; specific dimensions need to be determined through on-site measurement. Three-wing swept-back design
It should be the same; during discussions with the manufacturer, no difference was ever mentioned.
Reply to 4# sgh1966: I took a look at the assembly diagram; its mixer references two different part numbers, so the dimensions are likely different
Our factory uses Jinhua machines with 70-cubic-meter reactors; the sizes of the upper and lower impellers are the same, only the installation method differs
Reply to 6# clq20040107: The drawings for Jinxi Chemical Machinery are the same, but the dimensions vary among different manufacturers, so I’m confused. I’m just asking the moderator – do you have the assembly diagram?
The impellers in our workshop are of the three-blade swept-back type. I checked the overall assembly diagram of the polymerization reactor; the weight of the upper stirrer is 201.8 kilograms, while that of the lower stirrer is 243 kilograms. Therefore, the sizes of the two impellers are different.
Our factory’s Shanghai Sensong polymerization reactors use a double-layer, three-blade swept-back design, with identical dimensions
The one in our factory is 110 cubic meters; we repaired the reactor a few days ago and just took a look – it seems to be of the same size.
