WAYS FOR ENERGY SAVING IN PUMPING PLANTS FOR MELIORATION AND IRRIGATION SYSTEMS
DescriptionProblems concerning energy saving become more urgent in the connection with permanent increasing of electricity price and enactment of the law regarding energy efficiency and energy saving. Regulated electric drive has been using widely for energy saving within pumping plant. Appropriate equations were carried out for adequate regulation of technology process of water travel and energy supplying. The analysis of criterion function for optimization and efficiency factor for specific elements as well as whole system makes it possible to find out the optimal system parameters and define energy saving work conditions

RESEARCH AND MODERNIZATION OF CRUSHING AND SORTING EQUIPMENT OF SAND AND SAND-GRAVEL MIXTURE
DescriptionThe object of studying was CMD-108 crusher. The aim of this scientific article is studying kinetic and dynamic parameters of crusher operating devices. As a tool of studying there were used methods of mathematic analysis, theoretic mechanics and physics. As a result of theoretic studies there were defined speeds of various points of the crusher operating devices as well as there were obtained the values of dynamic loads on them and given recommendations on optimization of the crusher operating conditions and its designs. There was also determined an optimum zone of the material crushing from the viewpoint of operating life of the hinged joints of movable jaw enabling to reduce to minimum dynamic impact components of the reactions of the supporting joints of the movable jaw which increases their operating life
