摘　　要：介绍一种动静环式过滤机的结构原理,运用ANSYS有限元软件对动静环式过滤机静环的受载特点进行模拟,对其变形进行比较。有限元模拟结果表明,相比较于2 mm的静环厚度设计,3 mm至5 mm的静环厚度更能有效地避免挤压变形,为设计方案的可靠性提供了依据,提高了过滤机的使用寿命。A design scheme of volute screw solid-liquid separator is presented in this paper.Strength and deformation of stationary ring undertaken complex load are checked by using finite-element code.The result of numerical simulation shows that cmpared to the initial design of 2mm,3mm to 5mm thickness of stationary ring can effectively prevent extrusion deformation.The analyses provide a basis for design scheme,and improve the service life of the volute screw solid-liquid separator.
