DESIGN AND FABRICATION OF ADVANCED MOTORIZED WATER PUMP USING SCOTCH YOKE MECHANISM
The aim of the paper is to design and develop a water pumping system using scotch yoke mechanism. The reciprocating motion of the plunger is utilized for the pumping action. The plunger is reciprocated with the help of a cam plate. By this action the water is pumped with very high pressure and to various heads. This can be utilized for various applications like lubrication in machines and water pumping in agriculture field. The cam plate gets the drive from the motor for its rotation and converts that rotary motion to useful dual side reciprocating motion. The motor is powered with the aid of electric power. Thus the water is pumped from source to various heads.
Every one of us will need of some kind of water source for drinking, bathing, washing clothes, preparing food and for irrigation. We may get the water from various sources like, lake, river, ponds, open well, bore well. So we have to pump the water from the source and use the water for the various purposes. Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work by moving the fluid. Pumps operate via many energy sources, including manual operation, electricity, engines, or wind power which usually come in many sizes that vary from microscopic for use in medical applications to large industrial pumps.
Generally, these mechanical pumps have numerous applications such as pumping water from wells, filtering of dust in the aquarium, filtering the ponds and aeration, also used in car industry for water-cooling and fuel injection, and finally in the energy industry for pumping oil and natural gas or for operating cooling towers. This Scotch yoke mechanism could be used for conversion between rotational motion and linear reciprocating motion. In general, this linear motion can take place in various forms depending on the shape of the slot, but mostly the basic yoke with a constant rotation speed produces a linear motion that is simple harmonic in nature.
The experimental setup consists of water pump whose pumping shaft is connected to the yoke plate of the scotch yoke mechanism the rotating disk consists of the yoke supporting pin is inserted into the yoke plate for controlling the translation motion.
The rotation of the plate is carried out with the help of motor. When the motor is turned on then it rotates the plate attached with it and this rotation is converted into translation by means of yoke plate, this translation motion activates the piston of the pump to take to and fro motion, the water is sucked and transmitted to the required designation.
• It is easy to suck the water with the minimum effort.
• Less cost.
• Simple in design.
• It draws water faster than normal hand pumps.
• Less time consumption operation.
• It is used in rural areas.
• As the installation cost of hand water pump with hand lever is low it is useful for poor people.
• It can be installed in all the public places.
