Hydraulic Pumps & Motors
The document provides information on hydraulic pumps and motors. It discusses the functions of pumps in converting mechanical energy to hydraulic energy. Pumps are classified based on displacement, delivery, and motion. Positive displacement pumps have little slip and can operate at high pressures, while non-positive pumps have large clearances and cannot develop high pressure. Hydraulic motors convert fluid power to rotary power and are classified as gear, vane, or piston motors. Piston motors can be axial or radial, with axial piston motors generating torque via pressure acting on pistons reciprocating inside a cylinder block.

compressed air articles
Compressed air is a versatile, reliable, and safe energy source that is used in many industries and applications. It has several advantages over other energy sources, such as a high output to weight ratio for pneumatic tools, forgiving nature that prevents damage when tools get stuck, and ability to be stored for peak demand periods. While less efficient than converting electricity directly, compressed air enables certain manufacturing processes and applications that would not be possible otherwise. It also provides a safe energy source for hazardous environments like oil and gas platforms. Modern compressed air systems aim to optimize efficiency, reliability, and productivity for industries.
Compressor
This document provides an overview of compressed air systems, including:
- The types of compressors and their characteristics such as reciprocating, rotary, centrifugal, and axial compressors.
- How compressors work using principles such as the ideal gas law and Bernoulli's equation.
- Factors that affect the energy consumption of compressed air systems such as inlet air conditions, pressure settings, piping layout and leaks.
- Methods for improving efficiency such as variable speed drives, capacity control, and detailed energy audits.
The document discusses compressed air systems in detail over 5 sections, covering the scope of work, types of compressors, selection criteria, performance comparisons, and system components.
Compressors and compressed air systems
This document discusses compressors and compressed air systems. It describes the main components of compressed air systems including compressors, filters, coolers, dryers, receivers and piping. It outlines the main types of compressors - positive displacement (reciprocating and rotary) and dynamic (centrifugal). It provides details on assessing compressor capacity and efficiency, and performance of the distribution system. The goal is to improve energy efficiency of compressed air systems which typically waste 70-90% of the energy from the compressor.
Methods to improve performance of compressed air system
1. The document discusses methods to improve the performance of compressed air systems, which are often inefficiently used and have problems like leaks.
2. It outlines 11 methods to improve efficiency, such as properly locating and sizing filters, adding intercoolers between compressor stages, eliminating leaks through testing, minimizing pipe lengths, and replacing pneumatic tools with electric ones where possible.
3. The presentation aims to reduce the energy consumption of compressed air systems by focusing on applications and following best practices.
Energy Conservation in Compressed Air System.
Compressed air systems can be inefficient, wasting up to 70-90% of the energy used to power compressors. Common issues include leaks, over pressurization, pressure drops, and misuse of compressed air for applications where other technologies would be more efficient. Implementing conservation measures like leak detection and repair, pressure optimization, proper sizing of distribution components, and replacing pneumatic tools with electric where possible can significantly reduce energy costs over the long term. Regular maintenance and monitoring compressor run times and pressures can also improve efficiency.
FABRICATION OF PNEUMATIC CONTROLLED RAMMER STRIKER FOR MOULDING PROCES.pptx
This document provides details on the fabrication of a pneumatic controlled rammer striker for moulding processes. It includes an introduction describing the role of project work in technical education. It then provides a synopsis of the project, which is to develop a ramming mechanism using a double acting cylinder controlled by a solenoid valve to increase productivity while overcoming labor shortages. Construction details, the working principle, and applications are described. Diagrams of pneumatic components and circuits are also included.
Automation 4.0
Pneumatic systems use compressed air to achieve low-cost automation in industries. They are widely used by small and medium enterprises to reduce costs through decreasing machine investment, process time, and increasing productivity and quality consistency. Pneumatics offer simple and easy control through pneumatic components like cylinders, valves, and regulators. Common applications include pushing, pulling, lifting, feeding, clamping, and pressing operations in manufacturing assembly lines, packaging, bottling, vehicle cleaning, and more. While pneumatic systems are lighter and easier to control than hydraulics, they typically operate at lower pressures of 5-10 bar.
Pneumatic engine
The document describes the experimental setup of a compressed air vehicle that uses compressed air instead of fuel combustion to power an engine. A double acting pneumatic cylinder is used to create reciprocating motion when supplied with compressed air from an air compressor. This reciprocating motion is converted to rotary motion using a connecting rod and crankshaft, which can then power vehicle wheels. The key components of the system include the pneumatic cylinder, solenoid valves, relay sensors, relief valves, connecting rod, crankshaft, and air flow tubes. The working principle involves compressed air entering the cylinder to move the piston and crankshaft on the intake stroke, then expanding on the power stroke. This eliminates combustion emissions compared to

Pneumatics
- 2. SUMMARY - Pneumatic definition - 10 aplications - Hydraulics - 10 aplications
- 3. What is the pneumatic? Pneumatics is a section of the technology is the study and application of gas pressurized fluids as transmitters of energy to produce mechanical motion . Air , one of the most used pressurized gas is a compressible fluid , so, the volume changes depending on the pressure and temperature. If power is applied to increase the air pressure reduces the volume , then the stored energy can return when allowed to expand , according to the ideal gas law . When air is used as a pressurized gas it is called compressed air. Pneumatic systems are mostly used in industry ; factories are usually equipped with compressed air or compressed inert gases systems . Such systems are useful because it provides a central electric compressor power cylinders and other pneumatic devices using solenoid power supply is capable of moving more inexpensive , secure , flexible and reliable than other types of devices and electric actuators like motors . Another advantage of these techniques is the small amount of energy is lost in the drive mechanism , so , its performance is quite high .It is called Pneumatic energy to the differential air pressure used to cause movement in different systems .
