Our hydraulic cutters are suitable for material with uniaxial compressive strength ranging from 500 to 25,000 pounds per square inch. All of our products can be utilized in a variety of applications from rock excavation, trenching, demolition and concrete, to underwater cutting, tunneling, and scaling.

The Sodium Lamp - How it works and history

You often tend to see sodium vapor lamps along the roads and parking spaces. The basic principle behind the working of sodium vapor lamp is passing electric current through sodium gas to make the gas emit light. This is called photoelectric effect.There is a U-shaped arc tube made of glass.

How does sodium vapor lamp work? - attemptNwin

Sodium vapor lamps are some of the most efficient lamps in the world. They have an efficiency of up to 190 lumens per watt compared to an incandescent street lamp which has between 15 and 19 lumens per watt. High pressure sodium (HPS) lamps low pressure sodium lamps (LPS) Compared to LPS lamps, high ...

Sodium-vapor lamp - Wikipedia

A sodium vapor lamp is a lamp that uses sodium to create light. It can come in a high pressure or low pressure format. High pressure lamps have more components than low pressure and contain other substances such as mercury. The lamp produces a clarity of light that creates vivid color from objects illuminated by it.

The Construction and Applications of Sodium Vapour Lamps

It is very difficult to get any material which is free from corrosion in presence of sodium vapour in high temperature and pressure. This was the main difficulty of producing high pressure sodium lamp.In 1959, the development of polycrystalline alumina (PCA) opened a new path to introduce the high pressure sodium vapor Lamp, as this …

How Does a High Pressure Sodium Ballast Work? | …

In a low pressure sodium vapour lamp, argon or neon gas is first heated up to emit a slight red or purple glow. The heat from this warms sodium metal in the light to the …

High Pressure Sodium Lamps or HPS Lamps

Scientists have long been familiar with fact high luminous efficiency could be obtained by the use of sodium resistant glass, the sodium vapour lamp has now reached the practical stage.. Working and construction

Principle of working of a sodium vapour lamp - …

This could be due to the fact that a sodium vapour lamp contains neon gas and when a current is passed through the two electrodes in the lamp the neon gas becomes ionised and … shines red until vapourisation occurs and the sodium cause the typical characterised yellow.
