CONTROL OVER FLOW RATE AND DISPENSING OF LOOSE MATERIALS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to industrial control over consumption and batching of loose materials and can be used in loose materials processing. Proposed method comprises material feed to vanes of turbine fitted on motor rotor. Motor stator is supplied from control power supply via stator winding commutator, conversion and display of stator current strength on display. Note here that fed material bulk is increased in portions to register the stator circuit current. By fractional increase in fed material amount and registration of rotor angular velocity, functional relationship "difference between working current and idling current - material mass a second" is constructed. Here, time of material stay on turbine vane is registered. Then, material is continuously fed. Required portion is defined as the product of material instantaneous mass derived from aforesaid relationship by time interval of rotor angular working speed action during action of difference between working current and stator idling current.EFFECT: higher accuracy.2 dwg
