| Popis: | A new method for calculating the setting torque magnitude of the electric drive in the electric drive shut-off system as the main elements ensuring the safety of oil pipelines and main gas pipelines is presented. The method allows to calculate a sufficient value of the torque of the drive adjustment with a minimum volume of input information about the system elements characteristics (electric drive, shut-off valve, control system) and to ensure that the actual torque is met when the system is completely stopped by the calculated torque specified by static methods. Clarification of the tuning parameters is carried out by means of experimental determination of environmental leaks with a step-by-step decrease in the torque within the regulation of the electric drive. The use of the technique at the design stage allows, during the operation of the systems, to reduce undesirable loads arising in the shut-off valves from the side of the electric drive, ensuring reliable operation of pipeline systems transporting mineral raw materials. |
