When the stacked screw sludge dehydrator was introduced in the early days, the commonly used names in the field of sewage treatment were MDS30 1, MDS302, MDS404 and so on. MDS is the abbreviation of multi-disc spiral press and the English name of piled spiral sludge dehydrator.
With the continuous branding of various manufacturers, naming methods pay more attention to brand promotion, and most of them adopt the modes of English abbreviation of brand name+English abbreviation of product name+model number. Take environmental protection in Yu Hui, Jiangsu Province as an example, the model number is YHDL30 1.
The letters in front of the model of the spiral sludge dewatering machine may change, but the numbers behind it (such as 20 1 and 30 1) will not change, representing the basic model of the spiral sludge dewatering machine. Some manufacturers who only produce stacked screw sludge dehydrators directly call them 30 1, 302, 404 and other models.
Then, how to define the basic model of stacked spiral sludge dewatering machine, and what do the following 20 1, 30 1, 302 mean?
Yu Hui, let me explain:
30 1 indicates that the outer diameter of the spiral shaft is 300mm and the number of spiral shaft bodies is 1.
302 denotes that the outer diameter of the screw shaft is 300mm, and there are two screw shafts.
404 denotes that the outer diameter of the screw shaft is 400mm, and there are four screw shaft bodies.
And so on: that is, the front integer represents the outer diameter of a single screw shaft, and the rear mantissa represents the number of screw shafts.
