METHOD FOR DECREASE OF DYNAMICAL LOADS IN PUMP COMPLEX WITH CONTROLLED FITTINGS

摘要

A method for decrease of dynamical loads in pump complex with controlled valves consists in formation of non-uniform rate of closing shutoff-control slide by means of uncontrolled asynchronous electric drive with several velocities of rotation. According to the utility model to the uncontrolled asynchronous electric drive of the slide one additionally connects frequency converter and external source of reserve power supply.
