Известен сепаратор, содержащий корпус, крышку, внутренний конус, лопаточный аппарат с лопатками, каждая из которых оснащена валом, сальниковым уплотнением и вынесенным рычагом [ 1 ]. · JKnown separator containing a housing, a cover, an inner cone, a vane apparatus with blades, each of which is equipped with a shaft, stuffing box seal and remote lever [1]. J

Известный сепаратор ненадежен в работе и сложен ввиду наличия механических и температурных перекосов вертикальных валов лопаток во втулках, установленных в крышке се- , паратора, ведущих к заклиниванию лопаточного аппарата при большом числе лопаток. Перекосы лопаток создают механическое сопротивление, неравномерность закрутки потока и ухудшение сепарации. ₃ The known separator is unreliable and difficult due to the presence of mechanical and temperature distortions of the vertical shafts of the blades in the bushings installed in the cover of the cerator, leading to jamming of the blade apparatus with a large number of blades. Misalignment of the blades creates mechanical resistance, uneven flow swirl and poor separation. ₃
