Design And Analysis Of Automatic Pneumatic Reciprocating Water Pumping System

Abstract

Reciprocating pumps are those in which the oscillating motion of pistons, plungers or
membranes causes a fluid to move. In this respect an attempt has been made to increase the discharge by
making some modifications in the single-acting pump with the same input power. It has been placed
vertically and adjacently to the main cylinder. In our project, Single Acting Multi Cylinder Pump is of
positive displacement pump. Due to high precision work involving lower in cost, these pumps are widely
manufactured by most of the industries. This piston is reciprocated with the help of a scotch yoke
mechanism. This is rotated by the motor. The piston reciprocated does the pumping action. The water in
the tank at normal pressure is delivered to a high pressure after pumping. This high-pressure water is
utilized for various purposes like gardening, cooling water circulation etc. Scotch yoke mechanism is
used first in engines as it can produce high torque. It is also used in conventional machining purposes.
The models and drawings are to be made in CAD software like CATIA V5 and for the determination of
forces, and the fluid flow analysis of single-acting reciprocating pumps has been performed in Ansys.
The various parameters such as mass flow rate of fluid flow, velocity of the fluid flow, volume of the fluid
flow and force of the fluid flow have been considered in this paper. These parameters have been studied
for cylinder in an outlet to determine the performance of the pump. The results show that, using the same
input power used for the single-acting reciprocating pump, the total discharge of fluid of the pump has
been increased.
