ABSTRACT A 1.25KVA (2000W) inverter generator was designed, constructed and certified Ok. In this project, the design of the inverter generator is aimed at satisfying the need of converting, a D.C source of supply (12v battery) to an A.C voltage of 220v. The inverter range of output is between 200-220v. Since the inverter was designed to step-up voltage, the power transformer is being used as step-down transformer for charging and as step-up transformer for inverting. The control circuit e...
ABSTRACT The main objective of this project was to ensure a proper security to car being parked in garage against theft or an intruder. The circuit uses three NE555 timers; one of the NE555 was wired as a monostable oscillator and remaining two were wired as tone generator and amplified to obtain a maximum audible sound. However, pin 2 of the first NE555 was used as sensor part .When pin 2 has contact with human body or hand it will activate the IC1 which will also bias transistor and this t...
ABSTRACT When it comes to construction projects, landscaping work, and gardening, you need the right kind of equipment to finish tasks speedily and easily. One piece of equipment you would need is a motorised wheelbarrow. This is intended to carry bulky materials and heavy loads. There are a lot of equipments that can be used these days for projects that involve heavy work. It would be an advantage to utilize motorized equipment in order for you to do tasks efficiently. With these tools, it ...
ABSTRACT This project is concerned with the fabrication of as a single face pressurized kerosene cooker. The report shows the possible way in which the above mentioned can be designed, fabricated and maintained. Its also shows the strength and properties of the materials it is made of. Defects of the equipment can come through inability to maintain and inability to use well. It can be due to irregular cleaning of pressurized parts, exposure to rain, moisture and sunlight as well as i...
ABSTRACT This work on the construction and fabrication of a mobile deep freezer revolves around the concept of refrigeration. The concept of refrigeration revolves around the reverse Carnot cycle. This is a cycle involving isentropic expansion (at the throttling valve), isothermal expansion (at the evaporator), isentropic compression (at the compressor) and isothermal compressor ( at the condenser) Compression raises the temperatures of the refrigerant above that of its natural surrounding...
ABSTRACT Mechanical Engineering Department of the named Institute has many non – operational malhiues. Sequel to the fact, maintenance was poorly excuted which resulted to the breakdown deep freezer. Quality and effectiveness of machine maintenance were well observed. Also, a minimized maintenance and a highly successful repair was adopted. In other words during the repair and rehabilitation of the facility Deep Freezer, appropriate tools, cost and quality of materials were well...
ABSTRACT Books are used recoding of what is happening or event that has already taken place which can be storing information it is useful and for the information that such books contained not to cost it support to be properly kept and these can be done when those books are kept in a cool dry place and a place free from rodents and insects attacked Therefore, our contribution to proper storage of books is the deigns and construction of a metallic bookshelf that will be economically cheap an...
ABSTRACT This work is an attempt evolve a quicker and easier method of achieving Transportation. This will no doubt save considering human labour and time wasted involved in traditional manual method of transportation. To achieve this, preliminary experiment was first carried out to determine the optimum speed of the motor vehicle. Various design alternative s for achieving the design solution were sythesized and a choice of an economic method which would satisfy the objective was made. Base...

ABSTRACT The aim of this project is to design and fabricate a bench shearing machine which can complete favorably with the imported ones. this machine is designed and fabricate, using our cheap and available materials. Some qualities such as durability, reliability and portability are guaranteed. It is functional and can cut or shear a metal of up to 4mm thickness It is recommended for use in all the work shop cutting operation. The machine being operated manually is an added advantage to co...
ABSTRACT This Nylon sealing and cutting machine has an added advantage of making 800 sealed bags per hour. The constructional machines were sourced locally. The machine can cut and seal Nylon at a affordable cost. The constructional size of 31 cm x 7.5cm x 12.4 which comprises the following component. The sealing and cutting filament, the transformer with 1000 turns of wire for the secondary and about 1200 turns for the primary. Others includes the micro switch, telephone tape and a...
ABSTRACT This report covers all activities candied out to rehabilitate a faulty refrigerator. First and foremost, we diagnosed the faulty refrigerator using the basic instruments to know the faults. After which we bought the necessary standard items that caused the fault. We then started work on it by replacing necessary instruments. We finally listed it and found out that the objective was fully achieved. TABLE OF CONTENTS Title page Letter of transmittal Release page Approval page ...
ABSTRACTS The fabrication of a pressurized kerosene oven. This project has been fabricated with special economical needs for the small scale baking industries, wholesalers and distributors who import this type of baking oven from outside the country to supply the customers who wish to use it or those that cannot after gas oven can be used in baking any type of available within the tropics. It I am also be used in are where there are no source of electricity or gas. TABLE OF CONTENT Title ...
ABSTRACT FLUSHING OF THE CONDENSER The refrigerant gas let into the condenser through the compressor and the vacuum pump was connected to the condenser to absorb dirty. REFILLING OF GAS INTO THE COMPRESSOR Gas was refilled into the compressor due to shortage of gas and it was filled inside the charging value and refrigerant. CHANGING OF DRIVER STRAINER DUE TO BLOCKAGE The driver strainer was change due to blockage with the help of oxygen and acetylene welding. SPRAYING OF THE FRIDGE The comp...
