Multi-phase PMSM is usually used in situation of high reliability, military and high power transformation, such as circulation water motor in nuclear power station and warship propulsion system etc. .
This paper proposes the research of the circulation water-cool system in Balin petrochemical thermoelectricity enterprise's outdated region, and it brings forward a scheme for the circulation water stabilization, which also has been carried into execution and attains the purpose of using the water best.
In this article, the data acquisition and management system of the cycling water in heat power plant is detailed described, which is based on PLC control system. The system is constructed by SCADA(Supervisory control and data acquisition) and data management system, providing data collecting , transferring, monitoring, controlling and management.
Corrosion-electrochemical behavior of tube stills of a 18-10 steel combined with the case component members from plain carbon steels in circulating water of petroleum refineries is investigated.
We present the results from an experimental investigation of the methods of aerodynamic action on the processes of evaporative cooling of circulating water in a cooling tower.
When circulating water was heated by ascending heat flow, gold would be extracted, concentrated and transported from auriferous rocks and then precipitated in the masses during the late tectonic movement.
We describe the water chemistry of circulation heat-transfer systems (cooling and heat-supply networks) at which the pH value of the circulation water lies in the range 7.0-8.3.
In addition, the experiment indicates that this novel chiller is highly suitable for an air conditioning system with a low dehumidification requirement or a system with a large cycle flowrate and an industrial cooling water system.
The level of physical parameters is treated that corresponds to the interaction between molten core droplets and cooling water in the case of severe accident in a nuclear reactor.
It is shown that, among the materials considered, those holding most promise for the development of adsorption systems for cooling water are new composite selective water sorbents, primarily KSKG silicagel modified with calcium chloride.
A description of promising developments of the equipment for the ball-cleaning system of turbine condensers and filters for additional cleaning of cooling water is presented.
In order to promote fertility and productivity, the irrigation of recycled water onto water repellent soil may be an applied technology to be used in some areas of Southern Australia.
Batch equilibrium sorption experiments on Cd, Cr, Cu, Ni, Pb and Zn in their typical proportion in recycled water were conducted in water repellent soil.
The risk assessment for the application of recycled water onto water repellent soil is definitely necessary, especially for the metal cations with relatively weak sorption.
