Quick Details

Q: Construction Engineering, moving equipment and stationary equipment, respectively: 1, moving equipment refers to the rotating device driven by the drive (that is, energy consumption of equipment), such as pumps, compressors, fans, etc., the energy can be electric power, pneumatic power, steam power, etc..

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 main functions of construction equipment monitoring system?: The total of the console cameras and auxiliary equipment (such as camera, PTZ, shield) control generally adopts the bus mode, a control signal to the camera near the terminal in the terminal box decoding, decoding box will total console from the control signal encoding solution, a control action command signal, a variety of actions to go camera control and auxiliary equipment (such as lens zoom, pan rotation etc.). In the case of some cameras that are close to the control center, in order to save money, the command signal, which is the "on or off" signal, can also be sent directly by the console. In short, according to the composition of the system and requirements, can be considered in order to complete the overall console design requirements or order requirements.

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: How do the welding parts in the welding drawings of the machine parts indicate the technical requirements of the drawings?: With what groove related, open groove is not the same, marking is not the same, "welding structure" reference to our specialized courses

Q: China mechanical net: From Chinese GM parts, general machinery, hardware, tools, instruments, electrical appliances and related equipment, textile equipment, chemical equipment, agriculture, food equipment, construction equipment, environmental protection equipment, mining equipment, metallurgical equipment, financial equipment, commercial vehicles and accessories, machinery processing equipment, machinery processing industry machinery enterprises and mechanical products

Q: Construction machinery production need to deal with what documents?: At all levels of production safety responsibility system, mainly refers to: the legal representative of the safe production responsibility system; the responsible person in charge of safety production safety responsibility system; the technical director (Chief Engineer) production safety responsibility system; the safety department (Department) Changan production responsibility system; responsibility for production safety, the project manager; specifically (and) post safety responsibility system for production safety; construction technician (technician), safety production responsibility system; 8 class (Group) Changan production responsibility system; workers, production safety responsibility system. Departments responsible for production safety system, mainly in accordance with the functions of enterprises set up departments, the corresponding formulation of the responsibility system for safety in production.

Q: Mechanical bearings, all types? Roughly: The most representative rolling bearings, widely used, can bear radial load and two-way axial load. For high speed and low noise, low vibration occasions with steel dust cover or seal type bearing rubber sealing ring in pre filled with the appropriate amount of grease, the outer ring stopper bearing ring or flange, namely axial positioning, and easy to install in the housing. The size of the maximum load type bearing is the same as that of the standard bearing, but there is a loading groove in the inner and outer rings, which increases the number of balls loaded and improves the rated load.

Q: What functions should be achieved in mechanical structure design?: The main features of the mechanical structure design are: (1) it is a set of thinking, drawing and calculation (sometimes necessary experiments) in one of the design process, is involved in machinery design, the most specific, the largest volume of work, in the whole process of mechanical design, an average of about 80% of the time for the structure design plays an important role in the success of mechanical design. (2) the multi solution of mechanical structure design, that is, the mechanical structure that satisfies the same design requirement, is not the only one. (3) the mechanical structure design stage is a very active design link, often needs to cross repeatedly. Therefore, in the design of mechanical structure, it is necessary to understand the basic requirements of the mechanical structure from the whole of the machine
