Quick Details

Q: The building electrical iron pipe and the pipe line fixing member connected to what is called, what is called the iron pipe and the 86 fixed part of tin: This book is based on the characteristics of construction electrician, in accordance with the scientific, practical and applicable principles. The content is simple, the language is easy to understand, the form is illustrated, and the system, authority, operability is strong.

Q: What are the sectors of machine building and parts processing?: Industry to classify, it is not very strict. For example, the insurance industry, mining, energy, food, hotels, real estate services industry, garment industry, advertising industry, aerospace, aviation, chemical, chemical, construction, health care, education, training, computer, metal smelting, fire, police, soldiers, accounting, beauty, body, media, publishing, wood, paper retail, wholesale, agriculture, tourism, justice, lawyers, sports, sports, arts, entertainment, medical, art, design, banking, finance, Internet, music, dance, postal, courier, transport, consulting services.

Q: What is equipment manufacturing and machinery manufacturing? What's the difference between them?: At present, other countries in the world, including international organizations, have not put forward the concept of equipment manufacturing. The concept of equipment manufacturing industry is unique to our country. Its formal appearance was seen in the central economic work conference in 1998, which explicitly stated: "we must energetically develop the equipment manufacturing industry."". (central economic work conference: Economic Daily, December 10, 1998, first edition) The core of the manufacturing industry is equipment manufacturing. People do not have the same understanding of equipment manufacturing industry, and there is no consensus definition and scope definition. It is generally believed that the manufacturing sector consists of the equipment manufacturing industry and the final consumer goods manufacturing industry. Equipment manufacturing industry is the general term of the industry which provides the production technology and equipment for the simple reproduction and extended reproduction of the national economy, namely the machine manufacturing industry for producing machines".

Q: What is the use of spare parts prices in Chinese market by foreign companies?: But there is always somebody to ask, just like a college paper, where everyone can read or keep secrets, but collecting them and sending them to foreigners is a sign of treason

Q: How are the machine parts stacked?: Classification ah! Put small pieces of different sizes and functions into boxes and attach labels; larger items can be placed outside in a certain order (for example, function, length, value, etc.)

Q: What kind of electrical equipment do you have? What are the main components of each device?: The utility model relates to a distribution box, belonging to a primary equipment in an electric equipment. Electrical equipment includes primary equipment and two equipment. Primary equipment is mainly power generation, power transmission, transmission, distribution, electricity and other direct generation, transmission and consumption of electrical energy equipment, such as generators, transformers, overhead lines, power distribution cabinets, switches, cabinets and so on. The two equipment is the equipment that controls, protects, measures and so on. Building or general buildings, such as cables, power distribution cabinets, motors, switches, sockets, lamps, air conditioners, electric water heaters, electricity meters, cameras, telephones, computers, etc., are electrical equipment.

Q: How do the welding parts in the welding drawings of the machine parts indicate the technical requirements of the drawings?: Therefore, the medium carbon steel has the most extensive application in the medium strength level. Besides being used as building material, it is widely used in the manufacture of various mechanical parts. Welding: 1 the preheating is conducive to reducing carbon steel heat affected zone is the most

Q: How are buildings, installations and materials divided?: Equipment generally includes the following: (1) all kinds of equipment and the equipment with the arrival of accessories, spare parts and equipment attached to the body made of ladders, platforms, railings and pipes. (2) various gauges, instruments and automatic control devices, experimental instruments, instruments and meters in the main part of the equipment. (3) components of equipment, such as oils, chemicals, etc. attached to the equipment body.

Q: Mechanical bearings, all types? Roughly: The separable bearing is composed of a raceway and a needle roller and cage assembly that can be arbitrarily assembled with a punched thin raceway (W) or a machined thick raceway (WS). A non separable bearing is an integral bearing consisting of a precision machined raceway and a needle and cage assembly. This type of bearing can bear one-way axial load. With small space, it is beneficial to the compact design of machinery. Most of them only use needle roller and cage assembly, and the installation surface of shaft and shell is used as raceway surface.

Q: What functions should be achieved in mechanical structure design?: The design of mechanical structure is based on the overall design, according to the principle of the program to determine and draw a specific structure, in order to reflect the required functions. Is the working principle of the abstract concrete into some parts, the specific content in determining the structure of the material, shape, size, tolerance, heat treatment and surface conditions at the same time, we must consider the process, strength, stiffness, accuracy, and other parts of the relationship between each other and other issues. So, the direct product structure design is the technical drawings, but the design work is not a simple mechanical drawing, drawing only express design language, specific integrated technology is the basic content of structural design.
