This engineering project focuses on the Design and construction of a pneumatic water pumping machine. Water is a universal solvent and by implication is widely known as the most treasured natural resource since the beginning of the world. Consequently, the medium through which water can be transported and supplied to diverse locations for varied purposes has posed a problem in our society today. A lot of solutions have been suggested and put in place to remedy this problem. Water pumping machines, both mechanically, electrically and manually operated types have been designed and manufactured by different manufacturers to serve in several aspects of life such as for domestic purposes, in hospitals, educational institutions, oil and gas sector and so on. The primary aim of this project is to design and manufacture or construct a pneumatically operated water pumping system in which the pumping action is initiated through the air introduce to the impeller from the air compressor. Nigeria depends heavily on the importation of goods and machines. A shift from this trend requires the development of locally available technology. Available technology was utilized in the design and fabrication of the external gear pump. The design considered relevant theories and principles which affect the performance of a pump. The parts of the pump were produced locally from available materials. The discharge dropped with the increase in pressure head. | Abstract
This engineering project looks at the Fabrication and construction of window burglar proof. Burglar proofs are a major essential application to building structure activities for the beautification and security of the house such as school subtraction detached garage and high durability the ability to secure a good quality and high durability at a less affordable price to an average in Nigeria has been a problem. It aims to prevent animal and unwanted people into the building while is also maintain by painting to prevent corrosion of the burglar-proof. This window burglar-proof can also be modified and improved upon, this can be done by using best material suitable and that can withstand and resist the factors that will affect it, such as corrosion, heat, and bending. | Abstract
This engineering project focuses on the Design and fabrication of groundnut shelling machine. Groundnut shelling machine was designed and fabricated at the Department of Mechanical Engineering, Institute of Technology, Kwara State Polytechnic Ilorin aimed at increasing shelling/decorticating efficiency and eliminating drudgery associated with the traditional method of -shelling groundnut and other developed methods such as pedal-operated methods. The machine is powered by a 1.5 horsepower motor at a speed of 1440 revolution per minute. Performance investigation carried out show a good performance of the machine with decorticating efficiency, undecorticating efficiency, machine damage efficiency, cleaning efficiency and output capacity of 92%, 7.5°k, 3%, 85% and 120kg/hour respectively. It is recommended that a motorized oscillating decorticator for commercial production for human and even animal consumption be fabricated using stainless steel material for critical parts. | Abstract
This engineering project looks at Fabrication of metal panel door. Security of life and property cannot be overemphasized. Human beings need privacy in their various homes and offices which necessitate the need for doors among other security services. It has been a major challenge for the people to have doors of high quality and that are also durable at affordable prices by an average Nigerian. This project was done purposely to fabricate a metal panel door of high quality capable of giving maximum securities to life and properties at affordable prices. Locally available materials such as mild steel and cast of different sizes and shapes, forms and formats with a thickness of 1mm x 2mm were used with available indigenous technology without compromising the standard. The metal panel door consists of a frame unit, panel unit, stopper, hinges, and lock. Has its total dimension and weight to be 2135mm x 1220mm and 5639.8703N respectively. In other to prevent corrosion green anticorrosive (Glossy paint) was used. | Abstract
Installation of split air conditioning. The project is aimed at the operation of a split air conditioning system that may be applied for industrials, commercials, and residential comfort-cooling applications. Air conditioning is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants. It provides comfort by uttering the properties of the air, usually by cooling the air inside whether in homes, offices or vehicles. It is made of different types of metal frequently plastic and non - traditional materials are used to reduce weight and cost. Self-contained units that house the refrigeration system usually are encased in sheet metal that is protected from environmental conditions by a paint or powder coating. The working fluid which circulates through the air conditioning system is typically a liquid with strong thermodynamics characteristics like Freon, hydrocarbons, ammonia, or water. The manufacturing process and assembled part of split air conditioning systems are analyzed in this write-up. The air conditioning system achieved cooling through refrigeration cycle the compressor function is to continuously draw the refrigerant evaporator from the evaporator so that low pressure and low temperature can be maintained in the evaporator, the compressor sends the evaporator refrigerant to the condenser which condenses it into a liquid refrigerant. Then the expansion valve controls the flow of refrigerant from the high pressure condensing side of the system into the low pressure evaporator, the evaporator then receives the low pressure or low temperature fluid from the expansion valve and bring it in closed thermal contact with the load, the refrigerant takes up it latent heat from the load.. | Abstract
This engineering project looks at Modern washing machine, principles of operation and maintenance. The goal was to design, build and test a prototype modern washing machine that incorporates its principle and maintenance as a mechanical safety feature. The main problem was to develop an ergonomic and low cost solution while ensuring the safety and reliability of the system through-out it full range of motion. The purpose of this study is to gain information related to its development, to aid the removal of dirt’s and stains and in carrying out repairs and maintenance on modern washing machines. A modern washing machine structure includes, peddles or fingers to automatically agitate the clothing. Inside the cloth washer drum, the paddles turn the clothes through the water, the hole let the water in (from above) and out (from below). The rubber seal stops the water leaking out through the door.. |
