APPARATUS FOR CONTROLLING LEVEL OF INTERFACE OF OIL-WATER PHASES IN DEHYDRATORS

摘要

FIELD: petroleum and petroleum-chemical industries. SUBSTANCE: apparatus for controlling a level of oil-water phase interface in dehydrators includes the pickup 1, detecting the level of phase interface, the regulator 2 and the actuating organ 3. The regulator 2 has the integrators 4,5, the unit 6 for detecting time moments of the pickup switch-over, the switching member 7 and the adder 8. An output of the pickup 1 is joined with inputs of the integrators 4,5 and with an input of the unit 6 for detecting time moments of switch-over of the pickup 1, whose output is connected with a control input of the switching member 7. Outputs of the integrators 4,5 are connected with inputs of the adder 8, whose output is connected with an input of the actuating organ 3; an output of the integrator 5 through the switching member 7 is connected with a busbar of zero potential. EFFECT: enhanced quality of controlling a phase level in flow-through sealed reservoirs. 1 cl, 1 dwg
