- 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: Building materials, equipment, components and fittings products must have "three certificates" is what cards?
- Product quality certification, also known as product certification, internationally known as qualified certification. According to the 1991 implementation of the "people's Republic of China Quality Certification Management Regulations", the product quality certification is based on the product standard and relevant technical requirements, the certification institution confirmed by the certification and certification marks to prove that a particular product is in conformity with the relevant standards and technical requirements of the corresponding activities.
- Q: What type of industry does the machinery and building accessories processing belong to?
- There are only three tax categories in our country: 1 consumption tax, 2 VAT, 3 special tax (agriculture). Therefore, as long as the manufacturing or processing of industrial value added tax on enterprises. It has nothing to do with the economic nature, classification and categories of an enterprise.
- 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: Where are the mechanical pressurization air supply facilities set up?
- When the smoke proof staircase and antechamber antechamber, fire elevator or common antechamber parts can be opened outside the window, can use the natural ventilation, resulting in a stairwell with or common antechamber in the use of natural smoke exhaust with pressurized air supply arrangement of diversified combinations, and the two exhaust can not be shared.
- 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: Where does Heilongjiang do the most construction machinery?
- It is mainly used for national defense construction project, the construction of transportation, energy industry construction and production, mining and other industrial raw materials, construction and production, forestry and water conservancy construction, industrial and civil construction, city construction and environmental protection.
- 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 is the difference and connection between equipment manufacturing and machine building?
- When our company went to the training center of the Department of industrial engineering of Tsinghua University, the professor of Qinghua University told us about it. Equipment manufacturing industry is a general term for the equipment provided for the national economy and national security
