More Info About pin on disc tribometer

actually pin on disc tribometer which allows the friction coefficients of different lubricants to be accurately assessed and compared. Users in the field of automotive engine oils are not necessarily interested only in the lifetime of a particular lubricant but also in a quantitative method of determining the service frictional properties. This means that a service temperature of 100-140 C must be maintained during the test and that a load arm capable of compensating for thermal drift must be used ....etc

HIGH TEMPERATURE SUPER CONDUCTORS

ABSTRACT :

A substantial fraction of electricity is lost in the form of heat through resistance associated with the traditional conductors such as copper or aluminum. More than 15% of the world's generated electricity is los ....etc

solar based high efficient vacuum cleaner capable of capturing even 40 microns small dust

A vacuum cleaner, also known as a Hoover or sweeper and commonly referred to simply as a vacuum, is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from floors. The dirt is collected by either a dust bag or a cyclone for later disposal. In general we are using direct electrical power supply to the vacuum cleaner. The suction is the maximum pressure difference that the pump can create. For example, a typical dome ....etc

Abstract:
Tribometer is an instrument that offer precise and repeatable wear/friction measurement of a surface. Friction testing can be carried out in various environments to simulate the real life scenarios. Tribometer testing rigs can take numerous geometries but generally take the form of a loaded probe that impinges the sample that travels in a circular or reciprocating fashion. In this seminar we present different methodology used in advanced Tribometer and the working principle of Pin on disc Tribometer

Abstract:
pin-on-disk tribometer is an advanced Tribometer with precise and repeatable measuring of the friction and wear properties of combinations of metals and lubricants under selected conditions of load, speed and temperature. the elements of the tribometer are a pin sliding on the flat face of a disk rotating in a vertical plane, with provisions for controlling load, speed and oil temperature, and for measuring friction. The test oil is contained in a cup in which the disk rotates ,The pure sliding used in this test causes b ....etc
