In the system solar power has been used for cultivation. Solar photovoltaic cells convert energy into electricity through (SPV) effect. Generated DC voltage then converted in to AC by pump controller, this is as input of Variable Frequency Drive (VFD). The VFD acts a motor controller that controls submersible varying frequency and its supply. associated with controller. Regulated three phase ou...

In previous studies, active suspension system in conventional powertrain systems was investigated. This paper presents the application of active suspension system in parallel hybrid electric vehicles as a novel idea. The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...

A novel design for a differential pumping system has been investigated. This system allows windowless experiments in a soft X-ray beamline under normal atmospheric conditions. The new design consists of an aperture-based four-stage differential pumping system, based on a simple model calculation. A prototype system with a total length of 600 mm was constructed to confirm the validity of the des...

Numerical optimization methods offer a powerful new technology for pump users when combined with pumping system analysis software. Whether the design goal is to reduce first costs or life-cycle costs, this technology promises to significantly reduce pumping system costs and energy usage. Optimization methods work by automatically selecting pipe and pump sizes to minimize cost. Design engineers ...

A nonlinear mathematical model for the optimal operation of a parallel pumping station group was established with objective minimizing costs considering target quantity water extraction and flow unevenness between units each as constraints. The original is decomposed into several sub-models single multi-objective optimization lifting capacity pump coordinating variable. This constructed solved ...

Currently, the leading Russian oil companies engaged in the development of automatic control systems (ACS) oil equipment, to improve its efficiency. As an example of an object needed to optimize its work, a centrifugal pumping unit (CPU) can be specified. Frequency actuators provide an opportunity to run CPU in any algorithm, and many industrial controllers, are part of the automatic control sy...
