What Is a Mechanical Room?

Machinery (English name: machinery) refers to the general term for machines and institutions. Machinery is a tool device that can help people reduce the difficulty or effort of working. Items such as chopsticks, brooms and tweezers can be called machines. They are simple machines. A complex machine consists of two or more simple machines. These more complex machines are often called machines. From a structural and kinematic point of view, there is no difference between a mechanism and a machine, and they are generally referred to as machinery.

The word machinery comes from
1. Machinery is a combination of objects. It is assumed that it is difficult to deform the force when it is applied to each part.
Machinery is a combination of artificial physical components.
Definitely between the various parts of the machine
Mechanical Engineering and Technology
There are many types of machinery, which can be divided into various categories according to several different aspects, such as:
Mechanical drawing is the use of drawings to accurately indicate the structural shape, size,
Mechanical seals, also known as face seals, 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 of and several pairs of flat friction pairs consisting of a dynamic ring and a static ring.
The mechanical seal is a device for preventing fluid leakage formed by at least a pair of end faces perpendicular to the rotation axis 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 keep the two parts sliding relatively. The auxiliary seal of the compensation ring is a metal bellows called a bellows mechanical seal.
Note during installation:
1.Pay great attention to avoid
Mechanical engineering: based on the relevant natural sciences and technical sciences, combined with technical experience in production practice, research and solve all the theories and principles in the development, design, manufacture, installation, operation and repair of various machinery Applied subjects for practical problems. Machinery is one of the five major elements (human, capital, energy, materials and machinery) of modern society for production and service, and participates in the production of energy and materials.
A brief history of the development of mechanical engineering:
Various stone axes, hammers, and wood made and used by humans in the Stone Age,
1.Multifunctional design of components
The so-called component multi-function is that a component has multiple functions. It can produce multiple useful actions 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 positioning; in the mechanism of reciprocating motion In the middle, the stroke switch triggers the member. It not only plays the role of triggering mechanism for reverse movement, but also has the function of pushing the counter to record.
The multifunctional design of components can make the structure simple, compact and dexterous, and make the mechanism stable and reliable.
2. Simple and reliable motion exchange mechanism
The design of the motion conversion mechanism should select a reasonable mechanism according to the functional requirements and technical conditions used, and strive to achieve a simple and reliable transformation of the movement form and direction of movement, and can easily adjust the force and work position. The selection of the mechanism type must consider its inherent characteristics, for example: the speed reduction mechanism must have the functions of labor saving and smooth operation. On the contrary, the speed increasing mechanism does not save effort and is not very stable, but it has the effect of increasing the stroke (or increasing the angle of rotation) and delay.
The service area of mechanical engineering is broad and multi-faceted. All departments that use machinery, tools, and energy and material production need mechanical engineering services. In summary, there are five major service areas for modern mechanical engineering: research and development
Development of engineering machinery is an important piece of equipment for the construction of the national economy, and it plays an important role in the equipment industry. The sales revenue of China's construction machinery industry in 2007 was 222.2 billion yuan, ranking second in the world's construction machinery industry. From 2001 to 2007, the average annual growth rate exceeded 24%. The export value increased from US $ 224 million in 1998 to US $ 8.7 billion in 2007, a 37-fold increase in 10 years. China's construction machinery industry occupies an important position among its global counterparts. Its products have been exported to Europe and the United States and other construction machinery powerhouses. "Making Great Powers" and "Making Powers" move forward.
However, compared with the international advanced level, there is still a gap in the overall level of Chinese construction machinery, and some products are in the second and third-tier positions in the mainstream international market. Compared with large construction machinery multinational enterprise groups, the competitiveness of Chinese construction machinery companies Still weak. On the journey to becoming a powerful country in the field of construction machinery manufacturing, the development situation will be more severe and the challenges will be greater.
The situation facing us is the globalization of the economy and the market, the fierce competition, the personalization and facilitation of demand, the diversification of relevant stakeholders, and the rapid development of science and technology. This requires us to predict the future scientifically and accurately and respond quickly. Only in this way can the established advantages be maintained and surpass the advanced ones.
Humanistic care and sustainable development have become the concept of scientific and technological innovation in the industry. As an extension of human ability, engineering machinery has been developing together with the progress of human civilization. With the advancement of science and technology, human beings' continuous pursuit of quality of life and attention to dignity have raised many new topics for the development of construction machinery. China's construction machinery industry responds to demand, and attaches importance to strengthening the integration and integration between microelectronics, information technology, optoelectronic technology, new material technology and machinery manufacturing technology, and promotes product research and innovation in areas such as diversification, intelligence, and greenness.
Intelligentization and product specification extensions highlight the application space of humane care engineering machinery products. With the increasing demand for human quality of life, the application space has gradually expanded. It has been constructed from traditional areas such as construction, road construction, water conservancy and electricity, mining, etc. to urban narrow construction. Sites, agricultural construction sites in mountainous and hilly areas, and operating environments in warehouses, wharves, warehouses, cabins, farmhouses, gardens, horticulture, building floors and underground works, and large and extra large construction projects and mine expansion. Therefore, construction machinery is required to gradually extend to both ends, that is, miniaturization, large-scale, and ultra-large-scale. Large and extra large construction machinery products With the continuous increase of large and extra large projects, the market demand continues to increase. They have the characteristics of long development and production cycles, high scientific and technological content, and high added value. They represent the level of engineering machinery manufacturing in a country or an important enterprise. These products are mostly monopolized by several multinational companies in developed countries.
On the other hand, in order to improve production efficiency, reduce labor intensity, and improve working conditions, it has become a development trend to replace human labor with mechanical operations as much as possible. In order to meet the requirements of this engineering operation environment, the demand for small and micro engineering machinery will Rapid growth. The miniature products are not only subject to specific constraints, but also the design of appearance, color, and other aspects of the product are more and more integrated with nature and the environment, and it also highlights the humane care for respect for human nature.
The second is the development of the same product from a single function to multifunctionality and flexibility, that is, adding modular functional components on the basis of a universal product to achieve diversification of product functions; or through new modular design, manufacturing, and different modules The flexible combination between them to achieve functional diversification, the traditional division of engineering machinery product categories will be challenged. Engineering bulldozers should be extended to the ends of micro, small, large, extra large, etc., to develop multi-functional, multi-purpose, energy-efficient products and corresponding auxiliary function modules that meet the requirements of different working conditions such as wetlands, deserts, bushes and so on. Loaders should develop large-scale environmentally friendly products with large bucket capacity, large engine power, large breakout force, large tipping load, large traction, and low exhaust emissions, as well as loadable, graspable, side-loadable, lifting, economical A good multi-purpose product (such as a crusher).
Engineering excavators should extend the development of large hydraulic excavators, mini excavators, unmanned hydraulic excavators, remote controlled underwater excavators, underwater bulldozers, and underwater trenchers.
The wheeled crane should develop a multi-functional multi-functional product with advanced technology, high reliability, long life, good construction quality and high new technology content. Through the informatization and intelligence of construction machinery, the self-diagnosis and repair capabilities of various failures of construction machinery can be improved, the labor intensity of construction workers can be reduced, and the work efficiency and engineering quality can be improved. Under some special working conditions, such as high temperature, severe cold, high altitude, radiation, underwater and underground conditions, it can replace the construction personnel for intelligent and high-quality construction. The application of technologies such as automatic control and remote control of operating systems, precise positioning and control of construction, and fault diagnosis and monitoring to construction machinery will become increasingly common. New construction machinery products such as loaders, excavators, road maintenance machinery, forklifts, concrete mixing and transportation machinery and cranes developed by applying electro-mechanical-hydraulic integration technology, electronic computer technology, monitoring and control technology, and integrated technology of these technologies will continue to appear.
