This paper aims to analyze automatic protection and control measures at pump stations in the event of constant accumulation groundwater water dripping from pump, leading flooding station engine room. To prevent this, pumping station's machine room should monitor level leaks and, promptly, automatically remove excess with a pump. The is collected special reservoirs. From these, ERSU series senso...
The aim of the research is to identify hydrodynamic regularities in improvement operating modes water supply structures pumping stations with vertical vane pumps. authors studied conditions for supplying station and flow path pumps OP2...OP10 type. curvature jets causes swirl front impellers, directed counterclockwise units located left axis direction clockwise - right. With such a structure, m...
Introduction & Objective: Noise exposure, risk exposure in a wide range of work station, especially oil and gas industry and related companies is considered. This study was carried out to evaluate the noise before and after corrective action in 11 operational units of tanks and transportation in Abadan oil refining company. Methods: First, the basic information including the location of noise ...
After the establishment of the first quarantine station in the Republic of Ragusa (modern-day Dubrovnik) in 1377, the states and principalities of Italy developed a sophisticated system of defensive quarantine in an attempt to protect themselves from the ravages of plague. Using largely unknown and unseen historical maps, this paper reconstructs the extent and operation of the system used. It i...
This research was conducted in the Lower Ping River Basin downstream of the Bhumibol Dam and the Lower Wang River Basin in Tak Province, Thailand. Most of the tributary streams of the Ping can be considered as ungauged catchments. There are 10pumping station installation at both river banks of the Ping in Tak Province. Recently, most of them could not fully operate due to the water amount in th...
About 20% of the electricity produced in the world is consumed in rotary equipment for conveying fluids such as water, gas, air, and other liquids, while the loss of energy consumption in this sector is more than 60%. The aim of this study is to evaluate different efficiencies in the pumping stations in the pressurized irrigation systems to address low energy efficiency issues in the pump stati...
ABSTRACT: Recent theoretical work on stream depletion and water level responses to pumping a well near a stream include the (semi-) analytical solutions by Hunt (1999), Zlotnik and Huang (1999), and Butler et al. (2001). Yet, few field studies assessed the limiting assumptions and physical concepts inherent in the theoretical models. A long-term study of stream depletion under typical condition...
