Abstract

The invention provides a coke quenching pump control method and system, which are used for solving the problem that greater damage is brought to equipment due to the water hammer action after a coke quenching pump in the prior art is stopped. The coke quenching pump control method comprises the following steps of: after receiving a stopping signal of the coke quenching pump, enabling a hydraulic valve at the outlet of the coke quenching pump to execute a closing travel, and starting a first delay, wherein the duration of the first delay is longer than that of the closing travel; and stopping the coke quenching pump after finishing the first delay.

Description

technical field [0001] The invention relates to a coke quenching pump control method and a coke quenching pump control system. Background technique [0002] At present, high-level tank coke quenching technology has appeared in the coke quenching process of the coking workshop, that is, the coke quenching pump first puts the quenching water to the high-level tank (about 30 meters from the vertical height of the quenching pump outlet). During coke quenching, the electric valve controls the flow of water in the high level tank to quench coke. The start and stop of the coke quenching pump is controlled by the liquid level of the head tank. In order to enable the coke quenching pump to start under light load, a hydraulic ball valve is installed on the outlet of the pump, which opens after a delay after the coke quenching pump starts, and closes after the pump stops. At the same time, a non-return valve is installed on the pipeline to prevent the water from flowing back after th...
