在进行挤泥机结构设计时 ,计算挤出压力是必不可少的关键一步。虽然我们不必为公式的选用犯愁 ,但各公式计算结果的准确性却着实让人难以接受。1 问题的提出以常用公式σ =ｋ·60·ｐｓ·ｎ·ｔ 为例 (式中σ为挤出压力 ;ｋ为功率综合利用系数 ,一般ｋ =0 .2 50 .4 0 ;ｐ为电?
Calculating the extrusion pressure is a crucial step in carrying out the structural design of a puddle. Although we do not have to worry about the selection of formulas, the accuracy of the results of the formulas is really unacceptable. 1 The problem is raised with the common formula σ = k · 60 · ps · n · t as an example (where σ is the extrusion pressure; k is the power utilization coefficient, generally k = 0.250.400; p is the electricity ?
