Design and Fabrication of Piston Operated Water Pump – Mechanical Project

ABSTRACT
The technology of pneumatics has gained tremendous importance in the field of automation from old fashioned timber works, machine shops and space robots .Certain characterizes of air have made this medium quite suitable for used in modern manufacturing and
production industries. It is therefore important that technicians and engineers should have knowledge on pneumatic systems air operated valves accessories. Pneumatic system consists of a compressor plant, pipe lines control valves and drive members. The air is compressed in an air compressor and from the compressor plant the flow media is transmitted to the pneumatic cylinder through a well laid pipe line system. So keeping in mind about the importance of pneumatic system are introducing a project called Automatic pneumatic water pumping system. Here all need is a compressor pneumatic cylinder, pneumatic cylinder, piston pump. The aim of the project is pneumatic operated piston water pump. The piston is reciprocated with the help of a pneumatic cylinder solenoid valve. There are two cylinders are used in this project, one for pneumatic cylinder and another one for hydraulic cylinder. This pumping system also can be used in pumping of water supply in agriculture lands, Industrial pumping and also in domestical applications.

INTRODUCTION
The aim of the project is pneumatic operated water pumping system. Radial plunger pneumatic operated water pumping system are pump in which the piston is provided for the pumping action. The piston is reciprocated with the help of a pneumatic cylinder.

A pump is a Mechanical device which converts mechanical energy into hydraulic energy.

This pump is classified into two types;

TYPES OF PUMP
i. Positive Displacement and
ii. Non-Positive Displacement pump

CONCEPT OF MECHANISM

The air is compressed in an air compressor and from the compressor plant the flow media is transmitted to the pneumatic cylinder through a well laid pipe line system. So keeping in mind about the importance of pneumatic system are introducing a project called Automatic pneumatic water pumping system. Here all need is a compressor pneumatic cylinder, connecting links and a control system. The
aim of the project is pneumatic operated water pumping system, radial plunger pneumatic water pumping system are reciprocating pump is provided for the pumping action. The piston is reciprocated with the help of a pneumatic cylinder solenoid valve. There are two cylinders are used in this project, one for pneumatic cylinder and another one for hydraulic cylinder.

The two outlet ports are connected to an actuator (Cylinder). The pneumatic activates is a double acting, single rod cylinder. The cylinder
output is coupled to further purpose. The piston end has a water horning effect to prevent sudden thrust at extreme ends. The end of the cylinder two Non return valve is connected for both of the side. One Non return valve for suction side and another one non return valve are for delivery side.

WORKING PRINCIPLE

These pumps deliver a highly pulsed flow. If a smooth flow is required then the discharge flow system has to include additional features such as accumulators. An automatic relief valve set at a safe pressure is used on the discharge side of all positive displacement pumps. The performance of a pump is characterized by its net head h, which is defined as the change in Bernoulli head between the suction side and the
delivery side of the pump. h is expressed in equivalent column height of water.

Design and Fabrication of Piston Operated Water Pump

ADVANTAGES

This is of compact in size
Less Maintenance is enough
The oil or water pumped is of higher pressure
Quite running and smooth operation is achieved.
Higher efficiency
Full efficient positive displacement pump
Effective working principle
It does not have any Prime mover, like electric motor related to the unit.
As the air is freely available, we can utilize the air to pumping the water and hence it is economical.
Less Maintenance.
