Long-distance oil pipeline water hammer advance protection program demonstration device

Abstract

The invention provides a long-distance oil pipeline water hammer advance protection program demonstration device. The demonstration device comprises a power interface circuit, a controller module, a trigger circuit, a reset circuit, a program writing module, a time display screen and a direct current motor drive module. The entire demonstration device forms a long-distance oil pipeline water hammer advance protection system model. A water hammer advance protection program is written in the controller module, the controller module can display timing information on the time display screen in real time after the trigger circuit is started manually, the controller module detects the working state of a corresponding direct current motor at the timed time, and whether the corresponding direct current motor stops running or not is determined according to the setting of the water hammer advance protection program, so that the effect of the water hammer advance protection program automatically controlling oil transfer pump in every sit to stop running in a water hammer PLC (Programmable Logic Controller) is demonstrated after the water hammer advance protection program is triggered.

Description

Technical field [0001] The invention relates to a demonstration device, in particular to a circuit device for demonstrating the execution effect of a long-distance oil pipeline water hammer advance protection program. Background technique [0002] The water hammer advance protection program of long-distance oil pipelines is that when water hammer occurs in the oil pipeline, the water hammer PLC will automatically issue instructions to the upstream and downstream oil pumps, and the upstream and downstream oil pumps will immediately take corresponding protection actions to generate a pressure wave opposite to the water hammer. In order to avoid the damage to the pipeline, it plays an important role in the automatic protection of the pipeline. Demonstrating the execution process and execution results of the water hammer advanced protection program is of great significance for deepening the understanding of pipeline dispatchers and related technical personnel on water hammer adv...
