Analysis of the Algorithm Monitoring the Geometric Parameters of the Powered Support Based on Station Tests

Energy Science &Engineering, EarlyView.
ABSTRACT The powered roof supports in the longwall complex are placed and interconnected next to one another, typically about 125–250 units in a longwall face. It is an essential component in the longwall complex, which also includes a shearer (or plow) and an armored face conveyor.

Sand Erosion in Hydraulic Machinery

, 2004
The topic of this thesis is damage of hydraulic machinery due to sand erosion. This is a very broad topic in which all the aspects of design of hydraulic machinery namely material selection; mechanics of material and hydraulics are involved. The issue of sand erosion is equally important for operation and maintenance of hydropower plants.

Experimental and Theoretical Investigation on the Progressive Breaking Law of Thick and Hard Rock Strata in Deep Mining

Energy Science &Engineering, EarlyView.
This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...

Optimization of Energy Efficiency in Photovoltaic Water Pumping Systems Using Neural Networks

Energy Science &Engineering, EarlyView.
This study investigates an optimal control strategy for a photovoltaic (PV) water pumping system aimed at improving efficiency and autonomy in off‐grid applications. The system uses an induction motor with direct torque control and compares three maximum power point tracking (MPPT) techniques: neural network–based MPPT, Incremental Conductance (IC ...

Mass Exchange Flow Process in Side Channel Pumps: Effects of Different Geometrical Parameters

Energy Science &Engineering, EarlyView.
Figure 1 shows the Mass Flow Exchange (MFE) in the impeller at z = 7.5 × 10−3 m at 1.0 Q/QBEP, operating point for impeller scheme 1 (IMP 1), and impeller scheme 2 (IMP 2). The flow begins to exit the impeller at the outer radius and enters at the inner and central radii. IMP 1 exhibits more flow in and out compared to IMP 2. ABSTRACT The functionality
