Brief History of Mechanical Development

The symbol of human beings becoming “modern people” is manufacturing tools. The various stone axes, stone hammers, and simple and rough wooden and leather tools of the Stone Age were the pioneers of machinery that appeared later. The evolution from manufacturing simple tools to manufacturing modern machinery consisting of multiple parts and components has gone through a long process.

Introduction to Mechanical Seal

Mechanical seals are also called end face seals and are mainly used to seal the rotating shafts of pumps, compressors, hydraulic drives, and other similar equipment. The mechanical seal is a sealing device composed of a pair and several pairs of moving rings and static rings consisting of a plane friction pair.

The mechanical seal is a device that prevents fluid leakage by keeping at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to prevent fluid leakage. If the auxiliary seal of the compensation ring is a metal bellows, it is called a bellows mechanical seal.

Introduction to Mechanical Drawing

Mechanical drawing is a discipline that uses drawings to accurately represent the structure, size, working principle, and technical requirements of machinery. Drawings are composed of graphics, symbols, text, and numbers. They are technical documents that express design intent, manufacturing requirements, and exchange experience. They are often referred to as the language of engineering circles.
