Beschreibung
Zusammenfassung:	FIELD: testing engineering. ^ SUBSTANCE: method comprises simulating testing time variation of pressure, rate of its rising, and fluid temperature in the space of the pipeline to be tested, and comparing these parameters with the permissible values calculated on the basis of the strength characteristics of the pipeline material. The results of simulation determine the limit values of the control parameters of the pumping installation operation regimes. The device comprises pipeline to be tested, flow meter, pumping installation with sucking and delivery pipelines, passages for measuring pressure, fluid temperature in the pipeline, sucking pressure, delivery pressure, and speed of rotation of the shaft of the drive of the pumping installation, simulator of the pipeline pressure loading, and electronic units for storing information, calculating testing parameter, and generating control commands, and control unit connected with the actuators that control the regimes of the pipeline test. ^ EFFECT: enhanced precision and reliability of test. ^ 7 cl, 1 dwg
