Abstract:

During ecological researches and monitoring of the natural aquatic environment it is very often necessary to carry out filtration of water large volumes for extraction on filters the weighed components, and for subsequent analysis of mineral and organic suspension’s structure. The installations applied now for vacuum filtration have a number of essential restrictions. The most important deficiency of existing installations for vacuum filtration is the use of a leak-tight receiver with rigid design. At intensive filtration such receiver has to have a large volume that limits filtration installa

Abstract:

Transient vacuum drops in the milkline during one ordinary milking were recorded as a measure of vacuum stability in milking installations on 184 Norwegian dairy farms in the summer of 1997. An association between the frequency of vacuum drops and technical data including milkline diameter, length and slope, number of milking units and effective reserve was demonstrated. The direct connection between the transient vacuum drop and its cause could be established for most drops during milking observations. A high frequency of transient vacuum drops in the milkline was associated with a high level

Abstract The efficiency of milking dairy farm animals depends on the reliability of the milking equipment. Domestic milking machines are equipped with UVU 45/60 with a rotary vacuum pump that has an extremely limited service life, which is mainly due to imperfection of the lubrication system for its working bodies. In addition, oil loss along with the exhaust air leads to high lubricant consumption and environmental pollution. Analysis of modern designs of foreign rotary vacuum pumps shows that their operational reliability and service life are increased at the expense of maximum reduction of

After being in the focus of sciences' and industry's research and development activities for many years, the investigation of possible SF<sub>6</sub> gas-alternatives has been even more intensified after the revision of the European F-Gas regulation 517/2014. As natural gases yield a significantly lower dielectric strength in comparison to SF<sub>6</sub>, new challenges arise for the design of high voltage switchgear. Vacuum interrupters are environmentally friendly, reliable and able to withstand steep rising transient recovery voltages. In the last years, first instal

There are schemes of equipment for dehydration of damp dispersive waste of food productions (spirit grain, beer pallets, beet pulp, coffee and barley slag) analyzed in this article. These wastes at the majority of food enterprises of Ukraine are poured out onto the ground and that leads to environment pollution. However, in case of dehydration of these wastes to humidity 20 – 25%, they can be used as valuable additions to agricultural forages or as high-energy fuels. Thus, the problems of waste utilization and protection of nature from pollutions are resolved simultaneously. Besides, the enter

Abstract:

THE PURPOSE. The service life duration of wooden tangent towers used on overhead transmission lines with a voltage of up to 35 kV depends on the quality of lumber drying and subsequent impregnation. The drying of tangent tower workpieces is currently carried out by atmospheric or convective methods and is the longest and one of the energy-consuming stages of their production. At the same time, there are promising electrotechnological drying installations that can reduce the duration and improve drying quality at comparable specific energy costs. Such installations include vacuum high-frequency
