- Q:What is equipment manufacturing and machinery manufacturing? What's the difference between them?
- Equipment manufacturing, also known as equipment industry, mainly refers to the capital goods manufacturing industry, is to meet the needs of the development of the national economy departments and national security needs and manufacture all kinds of technical equipment industry collectively. According to the national economy sector, its range of products including investment manufactured goods machinery electronics and ordnance industry, belonging to the metal products industry, general equipment manufacturing industry, special equipment manufacturing, transportation equipment manufacturing, electrical equipment and equipment manufacturing industry, electronics and communications equipment manufacturing, instrumentation and cultural office the equipment manufacturing industry in the 7 major categories of 185 kinds.
- Q:How are buildings, installations and materials divided?
- Provisions on the division of equipment and materials for engineering construction? [answer] the division of equipment and materials in engineering construction is directly related to the reasonable division of investment structure, budget preparation and calculation of construction output value. In order to reasonably determine the project cost, strengthen the investment in the process of construction and management, the equipment and materials in the engineering construction is unclear, especially the universal controversial common problems and put forward the principle of division of fifteen copies of "national unified installation project budget quota" of the equipment and materials are divided, the provinces, autonomous regions and municipalities directly under the central government and the relevant departments of the State Council, the Department should be combined with the local situation, formulate rules for its implementation, and report to the Ministry of construction for the record.
- Q:What are the details of construction machinery parts in sand casting?
- (3) equipped with fittings, installation type air switch and air shower room installed in the furnace. (2) all kinds of vehicle tracks, transmitters, differential pressure and buttons are all materials other than the equipment body. (3) rotating filter network circulating water system for equipment, induction phase shifter, manhole and other various products embedded parts, clean bench, meter, scientific research and other functions of the machine, and pipeline safety device, railing, peep hole, ventilation air heater (1):
- Q:What kind of electrical equipment do you have? What are the main components of each device?
- Electrical equipment mainly refers to the transformer, reactor, capacitor, combination electric appliance, circuit breaker, transformer, lightning arrester, coupling capacitor, transmission line, power cable, grounding device, generator, condenser, motor, closed busbar, thyristor.
- Q:Where does Heilongjiang do the most construction machinery?
- All of the industry designated product range is roughly the same as that of China engineering machinery and other countries are also increased the railway engineering machinery, forklifts and industrial handling vehicles, decoration machinery, elevator, pneumatic tools and other industries.
- Q:What are the sub projects of a construction project?
- Appendix B Construction Engineering Division (sub branch) engineering, sub project division, B.0.1 Construction Engineering Division (sub branch), engineering, sub projects can be divided into table B.0.1. Table B.0.1 division number of construction works, sub works and sub projects
- Q:Construction machinery production need to deal with what documents?
- The person in charge of the enterprise, the person in charge of the project, full-time safety management personnel in "safety assessment qualified" column content according to the "three persons" Safety Assessment Certificate (fill in the contents of enterprise work safety management staff should meet the enterprise production safety management, the safety management department staff with the qualification to the total contract for not less than 5, not less than 3 professional contracting labor subcontracting, not less than 1; the construction site should be equipped with full-time safety management personnel according to the project size can be determined, according to the construction area of less than 10 thousand M2 project has at least a part-time staff of more than 10 thousand M2; project 1 - 2 full-time staff; more than 50 thousand M2 large sites, according to different professional safety management group);
- 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
- Q:What are the sectors of machine building and parts processing?
- 3., machinery manufacturing is also a kind of industry, many industries have parts manufacturing, processing links. Therefore, the processing of parts does not belong to a particular industry.
- Q:What are the mechanical drawing software?
- The 3D map only contact with SolidWords and Pro/E, Pro/E is better than Solidwords in general, but Solidwords is very simple to use, see Help tutorials you can learn to draw a three-dimensional map is not particularly complex easily to estimate a few days is enough. But any one of the two kinds of software, want to do not understand the words, expert advice is not really easy. UG and MasterCAM haven't touched much, but I've heard that it's suitable for processing stereogram.
