Technologies and means of protection in process of managing pumping stations

Abstract

This paper aims to analyze automatic protection and control measures at pump stations in the event of constant accumulation of groundwater and water dripping from the pump, leading to flooding in the pump station engine room. To prevent this, the pumping station's machine room should monitor the level of groundwater and water leaks from the pump and, promptly, automatically remove excess water with a pump. The excess water is collected in special reservoirs. From these, the ERSU series sensor, which is based on a contact electrode controller, does not allow it to constantly monitor the level in the storage tank within the required limits; therefore, as a completely automated system, it is unstable and cannot support the regulatory requirements for preventing it from starting one of its technical operations. The article discusses the positive aspects of technical solutions and experimental work in the DRV5023 IC with MSP430G2131 controller and no more than 2.7 mA consumer, NE555 IC-based timer and pump mode, stable contactless sensor, sensor-based automatic monitoring, and pumping system. The results are given. (12-17 seconds.) Preparation to start the pumping process is also a standard 4.7 V. power supply circuit. The work is based on production experience and is innovative.

Development of the theory of complexly closed city electrical networks

“…Under one general plan, under one cadastre, where there will be no new construction. As a result, it is possible to use complex electrical networks using digital automation when designing power supply in cities [27][28][29][30][31][32][33][34][35].…”

Hydrostatic method in an adapted device level control for on-farm channels

“…Thus, the level h measured in the object, changing, changes the value of the water column (H -h) in the measuring tube in accordance with expressions (1 and 2), which sets the sensitive element of the differential sensor in motion [2]. This movement can be converted into the required electrical output signal using the plunger 5 for inductive transducers.…”

Developing logical steps to integrate technical university students into the virtual reality laboratory learning environment

“…-The U.S. Department of Education's data from 2020 presents a compelling argument for VR, highlighting a 15% boost in retention rates for complex subjects when taught through VR labs as opposed to traditional methods [13][14][15][16][17][18][19][20].…”
