Title:
OPTIMIZATION CONTROL METHOD FOR RUNNING INTERVAL OF EJECTOR
Document Type and Number:
WIPO Patent Application WO/2018/077048
Kind Code:
A1
Abstract:
An optimization control method for running interval of an ejector, comprising the following steps: approximating the relation between primary flow pressure of an ejector and critical back pressure to a directly proportional linear relation, and determining a proportionality coefficient K* at a critical point of the ejector according to an optimal primary flow pressure value; dividing a working interval of the ejector into three parts according to the proportionality coefficient K* and a proportionality coefficient Ks; determining a working state of the ejector according to the working interval where the proportionality coefficient K of the ejector is located during practical work, and allowing the ejector to work at a stable running state by means of adjusting a pressure occurrence value.
