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 are the mixing arms of the concrete mixer?

Mixing arm concrete mixer is a component of the mixing arm itself and divided into lateral mixing arm (positive and negative points), stirring arm (also have positive and negative points), stirring arm below is the bearing seat connected, connected with 4 sets of high strength bolts with stirring arm. The top is equipped with wear-resistant mixing blades, connecting with mixing blades, high-strength bolts 2 sets. In addition, some manufacturers have designed mixing side bonded shaft swivel, is installed in the interval between the stirring arm fixed and rotated in two ways.

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: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:Building materials, equipment, components and fittings products must have "three certificates" is what cards?

Three is a business license, certificate of product quality, product quality inspection certificate. Business license is the legal provisions of some industries must be licensed, and handled by the competent department of the operating permit, such as tobacco monopoly license, drug business license, business license and other dangerous chemicals.

Q:What measures can effectively reduce the construction accident rate?

Hefei construction workers training _ security technology to prevent accidents: prevent the basic starting point of safety accidents is to take measures to restrict energy and dangerous material, to prevent the accidental release. Common safety techniques for preventing accidents are eliminating dangerous sources, limiting energy or dangerous substances, isolating and so on.

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: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 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.

Q:What are the safety protection equipment, machinery and equipment, construction machinery and accessories for construction enterprises?

Different types of work, security appliances are not the same. For buildings, the main safety helmets, safety nets, safety belts (San Bao), etc., for electrical operators, mainly insulated shoes, insulating gloves, insulation rod, insulation table, etc.
