Winches are rotating spools driven by motors that tighten or loosen cables. There are manual, electric, and hydraulic winches. Manual winches are operated by hand, electric winches use electric motors typically for vehicle recovery, and hydraulic winches use pressurized fluid to generate force for pulling large heavy objects. Winches should be capable of pulling at least 1.5 times a vehicle's weight and operate in temperatures from -20°C to +50°C. They have advantages like speed and efficiency but also disadvantages such as higher costs, maintenance needs, and risk of overheating. Winches are used in applications like marine vessels, vehicle recovery, construction equipment, and drilling rigs.

Scavenging in Diesel Engines by tharun kumar.pptx
Scavenging is the process of removing exhaust gases from the cylinder after combustion and replenishing it with fresh air. It is important for efficient combustion in engines. There are different types of scavenging methods based on the direction of airflow, including cross scavenging, loop scavenging, and uniflow scavenging. Uniflow scavenging provides the best scavenging efficiency but has more complex design requirements. Loop scavenging provides better scavenging than cross scavenging while remaining simpler than uniflow scavenging. The scavenging method selected depends on the engine application and design tradeoffs between performance, cost and complexity.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

WINCHES BY tharun kumar malapati.pptx
- 1. WINCHES Presented by : A.Seshu Kumar
- 2. Main View What is a winch? Types of winches Capability of a winch Avantages & Disadvantages Applications
- 3. What is a WINCH? • A winch is a rotating spool, driven by a motor, that can tighten or loosen a cable. • Components of winch DRUM Spool MOTOR
- 4. Types of Winches Manual winch operates a rotary handle manually to lift, carry, tow, etc. an object Electric winch For vehicle recovery Operated by electric motors Hydraulic winch used to pull large, heavy objects over long distances They use pressurized fluid to generate immense force and torque. This force is then used to drag, lift or push objects
- 5. Capability of a winch • should be able to pull at least 1.5 times the weight of your vehicle. • built for a working temperature range of between -20°C and +50°C. • One of the fundamental characteristics of the winch is the change in working radius that occurs as the winch drum fills and empties. Along with this change in working radius, the available line pull and line speed will also vary depending on the fullness of the drum.
- 6. • The selection of speed ranges is crucial to the maximum performance of the winch and is governed by a balancing of line speed versus pulling power. • Factor of safety for winch is around 3. • A sudden winch rope failure is quite possible, especially if the winch line is either shock loaded, or in this case the rope may have been overstressed by an undersized corner radius.
- 7. Advantages Disadvantages Speed Efficiency Reduces tension force by 50% Higher cost of installation requirement to lift the weight at higher speeds. Maintenance Complexity Over heating
- 8. Applications • Marine & fishing boats • Vehicle recovery • Construction equipment • Drilling equipment
