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

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

SEWAGE WATER AS THE SOURCE OF IRRIGATION AND PLANT NUTRIENTS


INTRODUCTION
Supplies of good quality irrigation water are expected to decrease in future because the development of new water resources will not keep pace with increasing water needs of agriculture, industries and municipalities. some of these future water needs can be met by using available water supplies more efficiently but in many cases it will be necessary to make increased use of municipal waste waters and agricultural drainage water. agricul ....etc

Biological Oxygen Demand (BOD)

BOD: Oxygen is removed from water when organic matter is consumed by bacteria.
Low oxygen conditions may kill fish and other organisms.

Sources of organic matter
Natural inputs-- bogs, swamps, leaf fall, and vegetation aligning waterways.
Human inputs-- pulp and paper mills, meat-packing plants, food processing industries, and wastewater treatment plants.
Nonpoint inputs-- runoff from urban areas, agricultural areas, and feedlots.

Wastewater Treatment Objectives

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

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
