The present gas transportation system can solve the problem of pressure stabilization in gas pipeline for meeting the need of big gas users. It consists of a controller, a pressure sensor, a microcomputer and a feedback unit of pipeline signal. The controller connected with the microcomputer controls the start and stop of the main gas-pump motor. When the pipeline rated pressure reaches a critical value, the motor is reduced so as to save energy. The soft start and stop can prolong the service life of the motor and the equipment. |
