Large water delivering and transferring unit preventive control method and device

Abstract

The invention discloses a large water delivering and transferring unit preventive control method. The large water delivering and transferring unit preventive control method is characterized by comprising the following steps that firstly, temperature, vibration degree and lubricating oil amount data of a water pump motor and liquid level data of a water inlet pond are collected, the collected dataare sent to a unit control cabinet, and the unit control cabinet sends control signals to the water pump motor, a pump control valve, an overhauling valve and a monitoring instrument; secondly, the unit control cabinet controls running of the water pump motor, the pump control valve, the overhauling valve and the monitoring instrument; thirdly, the unit control cabinet detects unit exterior suddenchange signals and unit interior signal faults; and fourthly, corresponding measures are taken according to the detection result for preventive control. The large water delivering and transferring unit preventive control method solves the problem that in the unit producing and running process, due to exterior technology sudden changes or self faults, sudden shutdown is caused, and damage is caused; and advanced preventive measures are taken for a unit in the production process, automatic detection is timely, and protection measures are taken.

Description

technical field [0001] The invention relates to the field of control of a pumping station unit for water transfer and adjustment, in particular to a preventive control method and device for a large-scale water transfer and transfer unit. Background technique [0002] In Yunnan, since water resources are distributed in high mountains and valleys, it is necessary to use large-diameter pipelines to upgrade water resources. Such projects have long pipelines, high lifts, high water pressure, high linkage technical requirements for water pumping stations, and high water volume. The distribution points are many and wide, and the overall operation risk control is difficult. Due to the huge flow of the water delivery system, the difficulty of operation control lies in the effective control of the water pumping station unit. In actual production and operation, when external factors and the unit itself fail , usually the sudden occurrence of the accident leads to extreme changes in the...

Problems solved by technology

[0002] In Yunnan, since water resources are distributed in high mountains and valleys, it is necessary to use large-diameter pipelines to upgrade water resources. Such projects have long pipelines, high lifts, high water pressure, high linkage technical requirements for water pumping stations, and high water volume. The distribution points are many and wide, and the overall operation risk control is difficult. Due to the huge flow of the water delivery system, the difficulty of operation control lies in the effective control of the water pumping station unit. In actual production and operation, when external factors and the unit itself fail , usually the sudden occurrence of the accident leads to extreme changes in the flow rate, and more seriously, the motor reverses and is damaged, so it is necessary to ensure that preventive measures are taken in advance for the unit during the production process
