Q:What is equipment manufacturing and machinery manufacturing? What's the difference between them?

Major technical equipment refers to the technical difficulty in equipment manufacturing, complete and strong, is of great significance, has a significant impact on the national economy need to be beneficial to the people's livelihood, complete sets of major technical equipment organizations across sectors, industries and regions to complete.

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: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 are the mixing arms of the concrete mixer?

Concrete mixer parts often due to operational mistakes and equipment damage, we should know that the correct use of Yantai mixer parts, mixing arm not only can complete the "workload" on time, but also to extend the service life

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: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?

Every industry has average tax rate, the contribution of each this argument does not exist, the industrial enterprise is nade VAT. The more value-added products you pay more.

Q:Changsha Sanlian Building Machinery Fittings Factory

In addition, you can check the input path, or the name of the unit on the map. It will remind you that there is no unit in Changsha and no way. In addition, we received a fax, saying that you want to order what goods, may wish to go to the other party's local industrial and commercial Red Shield network to check whether there is this unit

Q:What are the main functions of construction equipment monitoring system?

To date, the console has always been built into blocks, in terms of control functions and number of cameras. Can be assembled according to requirements. In addition, the character generator is also arranged in the total time and address on the console, the date and time, minutes and seconds are displayed by this device, and be put in place to monitor the address and name display. It can be recorded on the video recorder, so that it will be convenient for future reference.

Q:What functions should be achieved in mechanical structure design?

Mechanical structure design plays an important role in mechanical design. This chapter mainly discusses the characteristics, steps and mode of thinking of mechanical structure design. The working principle and design requirements of the machine assembly is a major factor in determining the structure and shape of the parts, followed by the selection of materials, manufacturing process requirements, which has the advantages of good manufacturability (processing and assembly). In addition, the perfection of the structure and shape of the parts has a great influence on the strength and stiffness.
