Basic Machinery Information

Machinery is the general term for machines and institutions.

Machinery is a tool device that can help people reduce the difficulty of work or save effort. Items such as chopsticks, brooms, and tweezers can all be called machinery. They are simple machinery. The complex machinery is composed of two or more simple machinery. These more complicated machines are usually called machines. From the point of view of structure and movement, there is no difference between mechanism and machine, which is generally called machine.

Basic Information about Modern Machinery

Any modern industry and engineering field need to apply machinery, that is, people’s daily life and more and more various machines are used, such as cars, bicycles, clocks, cameras, washing machines, refrigerators, air conditioners, vacuum cleaners and so on.

  • A machine is a combination of objects, and it is difficult to deform if force is applied to its various parts.
  • These objects must realize mutual, single, prescribed movement.
  • Transform the applied energy into the most useful form or into effective mechanical work.

The Main Classification of Machinery

There are many types of machinery, which can be divided into various categories according to several different aspects.

In detail…

For example, according to the function, it can be divided into power machinery, material handling machinery, crushing machinery, etc.; according to the service industry, it can be divided into agricultural machinery, mining machinery, textile machinery, packaging machinery, etc.; according to the working principle, it can be divided into thermal machinery, fluid machinery, Bionic machinery, etc.

The main products of the machinery industry include the following 12 categories:

Agricultural machinery: tractors, planters, harvesting machinery, etc.;

Heavy mining machinery: metallurgical machinery, mining machinery, hoisting machinery, loading and unloading machinery, industrial and mining vehicles, cement equipment, etc.;

Construction machinery: forklifts, shovel, and transport machinery, compaction machinery, concrete machinery, etc.;

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.

In 1799, French scholar Monge published the work “Descriptive Geometry”. Since then, the figures in the mechanical drawings have been drawn strictly in accordance with the projection theory of descriptive geometry.

In order to enable people to have a consistent understanding of the format, text, graphics, simplification of graphics and the meaning of symbols involved in the drawings, a unified specification was gradually developed and developed into a mechanical drawing standard.

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.

Brief Introduction of 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.

In detail…

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.

Mechanical seal composition

Mechanical seals mainly have the following four types of components:

  • Main seals: moving ring and static ring;
  • Auxiliary seal: sealing ring;
  • Compression parts: spring, push ring;
  • Transmission parts: bomb base and key or fixed screw.

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.

Matters needing attention when installing a mechanical seal

  1. Pay great attention to avoid installation deviation during installation.
  2. The compression of the spring must be carried out in accordance with the regulations, and no excessive or small phenomena are allowed, and the required error is 2.00 mm. If it is too large, the specific pressure of the end face will be increased, and the end face will be worn out. Too small will cause insufficient specific pressure and can not play a sealing role.
  3. After the moving ring is installed, the beard should be able to move flexibly on the shaft. After the moving ring is pressed to the spring, it should automatically spring back.

Precautions for Mechanical seals

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.

Mechanical Engineering Development

Mechanical engineering is based on relevant natural sciences and technical sciences, combined with technical experience in production practice, to study and solve all theoretical and practical problems in the development, design, manufacturing, installation, use and repair of various machinery Subject.

In detail…

Machinery is one of the five elements (people, capital, energy, materials, and machinery) for production and services in modern society, and it participates in the production of energy and materials.

Before the 15th to 16th centuries, the development of mechanical engineering was slow.

After the 17th century, the capitalist commodity economy developed rapidly in Britain, France and other countries. Many people devoted themselves to improving the working machinery needed by various industries and developing new power machinery-steam engines.

In the late 18th century, the application of steam engines was extended from mining to textile, flour and metallurgy industries. The main material for making machinery has gradually changed from wood to metal.

1. Multifunctional design of components

The so-called multifunctional component means that a component has multiple functions. Multiple useful actions can be generated during the operation of the mechanism.

For example: in the feeding mechanism, the pushing member has both the function of pushing the material in place and the function of positioning and clamping. In the clamping mechanism, the pressing member has both the function of pressing and the function of positioning; the mechanism is in a reciprocating motion. In, the trip switch touches the member. It not only plays the role of triggering the mechanism for reverse movement, but also has the function of pushing the counter to record.

The design of multi-functional components can make the structure simple, compact and dexterous, and make the mechanism run stably and reliably.

Understanding of Mechanical Design

Mechanical design, according to the requirements of use, conceive, analyze and calculate the working principle, structure, movement mode, force, and energy transmission mode, material and shape size of each part, lubrication method, etc. and convert it into a specific description to The working process as the basis for manufacturing.
