GSM based Control Panel for Agricultural and Domestic Water Pumps


Controlling devices using wired switches are common. A few years back
controlling devices using wireless remote control switches like infrared remote control
switch, RF based remote control switches were used. But these technologies have their
own limitations in terms of operation and range.


V Tec Electronics India has introduced a Control Panel Device for Agricultural
and Domestic Pump sets, ....etc

Hydraulic pumps and pressure regulation
A hydraulic pump (Figure 2.1) takes oil from a tank and delivers it to the rest of the hydraulic circuit. In doing so it raises oil pressure to the required level. The operation of such a pump is illustrated in Figure 2.1a. On hydraulic circuit diagrams a pump is represented by the symbol of Figure 2.1b, with the arrowhead showing the direction of flow.
Hydraulic pumps are generally driven at constant speed by a three phase AC induction motor rotating at 1500 rpm in the UK (wi ....etc

ABSTRACT



Electric rockets are the new embodiment in space technology. Conventional rockets generate thrust by burning chemical fuel. Electric rockets propel pace vehicles by applying electric or electro magnetic fields to clouds of charged particles or plasma to accelerate them. Efficient plasma engines are propelling the next generation of space probes to the outer solar system. Although these offer much lower thrust levels than their chemical cousins, they eventually enable space craft to reach greater speeds for the same amount of pro ....etc

COMPRESSORS, PUMPS, AND PIPELINE FITTINGS

B. S. Zakharov



It is shown that when sucker-rod pumps are used, fluid leakage in seals of plunger-cylinder and valve pair
through hole and radial slot is proportional to the area of the flow section and is also dependent on the
shape of the latter. A new type of mechanical seal has been developed that reduces leakage significantly
and increases efficiency and nonfailure operating life of piston or plunger pumps.
The key operational parameters of sucker-r ....etc

1.INTRODUCTION

A pump is a machine that draws a fluid into itself through an entrance port and forces the fluid out through a machine that draws a fluid into itself through an entrance port and forces the fluid out through an exhaust port. A pump may serve to move liquid, as in a cross-country pipeline; to lift liquid, as from a well or to the top of a tall building; or to put fluid under pressure, as in a hydraulic brake. These applications depend predominantly upon the discharge characteristic of the p ....etc

ABSTRACT:
Pistonless pump for rocket has been proved to be the most economical than piston pump or turbopump.
In pistonless pumps, piston is absent. It has very much less rotating parts than that of piston pumps or turbo pumps. So, it has less friction losses and there by it helps to improve the efficiency of the engine considerably.They can be easily installed in the rocket than turbopumps.Also,it reduces the weight of rocket.

RECIPROCATING PUMPS

each stroke displaces a definite quantity of liquid, regardless of the resistance against which the pump is operating. The standard way of designating the size of a reciprocating pump is by giving three dimensions, in the following order: 1. The diameter of the steam piston 2. The diameter of the pump plunger 3. The length of the stroke For example, a 12- by 11- by 18-inch-reciprocating pump has a steam piston 12 inches in diameter, a pump plunger 11 inches in diameter, and a stroke of 18 inc ....etc
