STEADY LEAK DETECTION DEVICE oil and oil products pipelines and electric-OFF UNIT

摘要

The proposed utility model is most applicable in the transportation of oil and oil products in the main and technological pipelines.; The solution of this object is achieved in that the pipeline by portions of pressure sensors and fluid counters connected communication lines to the terminals of the electronic signal receiving unit and a personal computer, and in that pressure sensors are equipped with two contact plates which communication lines are connected to the electric pump installation disabling relay and closing valves with electric drive.; The utility model is as follows. The operator includes electric pump unit. Petroleum or oil begins to be pumped through the pipeline. For permanent diagnosing the presence of leaks in a pipeline via fluid meter, pressure sensors, communications lines and the electronic unit receiving signals continuously produced fluid flow and pressure measurements in pipeline segments, which are output to the computer. The operator compares the received indications of fluid flow and pressure in areas of the calculated, based on the use and analysis of the database that characterize the transfer parameters. Then, the operator at values ​​of pressure and fluid flow beyond the specified interval specifies the leakage of oil and petroleum products on a particular section of the pipeline.; In the event of an emergency involving a depressurization pipe weld with subsequent leakage of fuel, arrow pressure sensor regards low threshold values ​​plate and closes it. When this link through the relay that cuts off the electric pump unit and through the actuator valve closes.; In the event of an emergency, associated with operator error when opening the valve, the failure of valves, pipe clogging paraffins at low temperatures or mechanical impurities arrow pressure sensor regard plate high threshold value, and closes it. When this link through the relay that cuts off the electric pump unit and through the actuator valve closes.; Evaluation of liquid flow rates and pressures on pipeline sections to determine the presence of leakage of oil and petroleum products, and use of the device to turn off electric pump installation and closing valves reduces the electric losses of fuel, reduces fire hazard pipeline operation and prevents its destruction, and also improves the ecological environment.
