Automated control system for pumping units for short-term emergency situations

Abstract

This article discusses and solves the issue that is often encountered at pumping stations on pumping units with a non-return valve in the system. In rural areas, there is often a short-term loss of voltage, which leads to a system failure. And also when the pump unit is switched off in a system with a non-return valve, water is not stored in the pipeline, and this leads to additional time for refueling the pump. It takes time to fill the pump, which stops the process. For continuous operation of the process in the control circuit, add the automatic reclosing circuit (ARC). This scheme solves these issues. Namely, with a short-term voltage loss, this circuit is used to restart the pump unit. Given the shortage of water resources in our country, watersaving technologies for irrigation of agricultural crops are of great importance. The pumping station as a whole, in addition to the above, is automated depending on the purpose and the specified operating mode. Often, automatic switching on the reserve, restoration of the stations after short-term power outages, and others are carried out. Although the station is a complete unit of structures, when automating the irrigation and drainage system as a whole, it is considered as a link in a single chain of system as objects, the work in which is interconnected and interdependent, which imposes additional, special requirements on the automation of the pump station.
