Presentation on vertical turbine
This document provides an overview of vertical turbine pumps, including their principles of operation, main components, construction, selection process, common issues, and maintenance. A vertical turbine pump uses a centrifugal or mixed-flow design with multiple stages to develop pressure. It consists of an impeller, bowl assembly, discharge column, and head. Factors like well depth and diameter, desired flow rate, and power source are considered for selection. Common troubleshooting issues involve startup failure, low flow, vibration, and capacity issues that can often be addressed through maintenance like cleaning or adjusting wear parts.
Double acting cylinder
Reciprocating engine cylinders are often classified by whether they are single- or double-acting, depending on how the working fluid acts on the piston.
Module 2 Hydraulic Actuators and Motors
Hydraulic actuators and motors convert fluid energy into mechanical energy or motion. There are two main types of hydraulic actuators: linear actuators (cylinders) which provide force to drive a load in a straight line, and rotary actuators (motors) which provide torque to drive a load in a circular motion. Actuators are used in applications like forklifts, aircraft control surfaces, and industrial machinery to perform tasks that require force, movement, lifting, or other mechanical work.
Gear pump
Gear pumps use meshing gears to pump fluids through displacement. There are two main types: external gear pumps which use two external spur gears, and internal gear pumps which use one external and one internal spur gear. Gear pumps are positive displacement pumps that pump a constant volume of fluid per revolution. External gear pumps are commonly used for lubrication and fuel transfer and internal gear pumps can handle high viscosity fluids like asphalt or chocolate. Both have advantages like precision and constant output, but also limitations like fixed flow rates and moderate pressure ranges.
Pumps
Pumps come in a variety of sizes for a wide range of applications. They can be classified
according to their basic operating principle as dynamic or displacement pumps. Dynamic
pumps can be sub-classified as centrifugal and special effect pumps. Displacement pumps can
be sub-classified as rotary or reciprocating pumps.

Centrifugal pump
The centrifugal pump consists of an impeller that rotates within a casing and uses centrifugal force to convert mechanical energy into hydraulic energy or pressure energy. As fluid enters the center of the impeller, the rotating vanes accelerate the fluid and discharge it outward into the casing. The casing, typically a volute, then converts the fluid's kinetic energy into increased pressure, causing the fluid to exit the pump at a higher pressure than when it entered. Proper pump operation relies on balancing factors such as suction head, delivery head, and mechanical efficiency to move fluid while avoiding cavitation that can damage pump components.
Hydraulic Actuators or Drive (Pneumatics Actuators)
The fluid discharged by the pump is directed to the ‘hydraulic actuator’.Theactuatorconvertthepressureenergyofthefluid into mechanical energy. There are 3 basic type of hydraulic actuator.
• Theactuatorsconvertthefluidpressuretoasuitablelinearor rotary motion.
• Linearmotion–Hydrauliccylinder
• Rotary motion – Hydro motor
• Rotarymotion–Semi-rotaryactuator
Centrifugal pumps
Centrifugal pumps work by using a rotating impeller to impart velocity energy to fluid and increase pressure. They consist of a casing and impeller on a shaft. As fluid enters the impeller eye, the impeller blades spin and eject fluid outward, increasing pressure. The volute collects and redirects the fluid, converting velocity energy to pressure. During operation, pressure imbalances across the impeller cause both radial and axial thrusts. Radial thrust is balanced through design of the casing and volute. Axial thrust is balanced through methods like balancing holes, wear rings, back vanes, or double suction impellers.

PUMPS
Pumps are devices that use mechanical energy to increase the velocity, pressure, or elevation of liquids and gases. There are two main types of pumps: positive displacement pumps and dynamic pumps. Positive displacement pumps apply direct pressure on a liquid using a reciprocating piston or rotating components. Dynamic pumps use centrifugal force to generate high rotational velocities and convert the kinetic energy of liquids into pressure energy. Common positive displacement pump types include piston pumps, plunger pumps, and diaphragm pumps. Common dynamic pump types include centrifugal pumps which contain an impeller and casing. Proper consideration of factors like net positive suction head are important for pump selection and operation.

Pumps are devices that use mechanical energy to increase the velocity, pressure, or elevation of liquids and gases. There are two main types of pumps: positive displacement pumps and dynamic pumps. Positive displacement pumps apply pressure directly to the fluid using reciprocating or rotating components like pistons, plungers, or gears. Dynamic pumps like centrifugal pumps use an impeller to impart kinetic energy and convert it to pressure energy. Key factors in pump performance include head, which measures pressure energy, and net positive suction head (NPSH), which must be sufficient to prevent cavitation damage to the pump.

Positive displacement pumps apply pressure directly to fluids using reciprocating or rotating components, while dynamic pumps like centrifugal pumps use impellers to impart kinetic energy and convert it to pressure energy. Key factors in pump performance include types of heads like suction head, discharge head, and total head. Cavitation can occur if a pump's net positive suction head available is less than required.
Pumps Part 2 students(1) (3).pptx
Pumps require energy to move fluids from one location to another by overcoming resistance. The amount of energy needed depends on factors like the height fluid must be lifted, pressure at the delivery point, pipe dimensions, flow rate, and fluid properties. Proper pump selection involves considering the total static head, friction head, velocity head, and pressure head. Pump performance is illustrated by curves showing relationships between head, flow rate, efficiency, power, and net positive suction head (NPSH) required to prevent cavitation. Cavitation can damage pumps and reduce performance, so sufficient NPSH must be provided.
Centrifugal pumps
Centrifugal pumps are dynamic machines that use centrifugal force to convert rotational kinetic energy to hydrodynamic energy. They have many applications including water supply and drainage. Key components include an impeller, casing, shaft, and diffuser. The impeller rotates and imparts kinetic energy on the fluid, increasing pressure and flow towards the outlet. Cavitation can occur if pressure drops too low and vapor bubbles form, undermining efficiency. Centrifugal pumps come in various types defined by factors like number of stages, impeller design, and position of inlets and outlets.

CLASSIFICATION-OF-PUMPS.pdf
Pumps are used to transfer and distribute liquids and can be broadly classified into two main categories: positive displacement pumps and dynamic pumps. Positive displacement pumps displace a fixed volume of fluid with each cycle of operation, resulting in a fixed flow rate. Dynamic pumps impart a tangential force to accelerate and increase the pressure of a fluid using rotating impellers. Common types of positive displacement pumps include piston pumps, diaphragm pumps, gear pumps, and screw pumps. Centrifugal pumps, propeller pumps, and turbine pumps are examples of dynamic pumps.
Pumps
Centrifugal pumps work by using centrifugal force to push liquid outwards from the center of an impeller. As the liquid passes through the impeller and then the volute casing, its kinetic energy is converted to pressure energy. The main components are the shaft, impeller, and volute casing. Centrifugal pumps are classified based on how fluid enters the impeller as open, semi-open, or closed. Radial pumps produce high pressure but low flow, while axial pumps operate at lower pressure but higher flow. Mixed flow pumps provide a balance of pressure and flow. Centrifugal pumps require priming to fill the impeller before startup.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Case study on centrifugal pumps
- 1. Case Study on Centrifugal Pumps (Series) Group No. 6 1515054 to 151563 TY B.TECH MECH
- 4. MAIN COMPONENTS OF CENTRIFUGAL PUMPS • Impeller: Centrifugal Pumps use impeller as the primary source for their pumping action. Its function is to increase the pressure of the liquid. • Casing: The casing contains the liquid and acts as a pressure containment vessel that directs the flow of liquid and out of the centrifugal pump. • Shaft: The main function of the shaft in a centrifugal pump is to transmit the input power from the driver to the impeller. • Seal: Centrifugal Pumps can be provided with packing rings or mechanical seals which helps prevent the leakage of the pumped liquid into the surroundings.
- 5. MAIN COMPONENTS • Bearing: The function of the bearing is to support the weight of the shaft assembly, to carry hydraulic loads acting on the shaft, and to keep the pump aligned to the shaft of the driver. • Coupling: The function of couplings is to connect the pump shaft and the driver shaft, and to transmit the input power from the driver to the pump.

- 7. CENTRIFUGAL PUMP IN SERIES CHARACTERISTICS
- 8. CENTRIFUGAL PUMPS IN SERIES - HIGH HEAD / LOW FLOW APPLICATIONS Putting your centrifugal pumps in series, or connected along a single line, will let you add the head from each together and meet your high head, low flow system requirements. This is because the fluid pressure increases as the continuous flow passes through each pump, much like how a multi- stage pump works. For example, if two of the same pumps are in series, the combined performance curve will have double the head of a single pump for a given flow rate. For two different pumps, the head will still be added together on the combined pump curve, but the curve will most likely have a piecewise discontinuity (meaning to curve with protusions as pictured in the next slide).
- 10. PUMPS IN SERIES WITH CONTROL - CONSTANT, HIGH PRESSURE APPLICATIONS In situations where a high, constant pressure is required, consider adding speed control to the final pump in a series. This configuration achieves the high pressure that is needed, while keeping a low flow, because the fixed- speed pump feeds into the speed-controlled pump, which adjusts its output with a pressure transmitter to add only enough head to maintain a constant pressure.
