Quick Details

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: 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 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: Changsha Sanlian Building Machinery Fittings Factory: The company in Changsha Hongdun business online can not find, provided by his address: two Changsha section of Xingsha Economic Development Zone Yuan Ming Road, I checked 114 specially call 12580 to booking the hotel near the road, not the road. Definitely a liar.

Q: What are the main functions of construction equipment monitoring system?: This belongs to information management engineering. The control part is the "heart" and "brain" of the whole system. It is the command center to realize the function of the whole system. The control part is mainly composed of the main console (some systems also have a secondary console). The main function of the total console: video signal amplification and signal distribution, image correction and compensation, image signal and image signal (including switching or voice signals) record, cameras and auxiliary components (such as camera, PTZ, shield) control (remote control) and so on.

Q: What measures can effectively reduce the construction accident rate?: Hefei construction workers training _ eliminate dangerous source: eliminate the risk source of the system can fundamentally prevent accidents. But an important point of system safety is that it is impossible to completely eliminate all sources of danger and that people can only selectively eliminate several specific sources of danger. Generally speaking, when the risk of a dangerous source is higher, we should first consider whether we can take measures to eliminate it. A dangerous source can be completely eliminated by selecting the proper production process, technology, equipment, reasonable design, structural form or suitable raw material. For example: instead of the power system with pneumatic or hydraulic system, to prevent the occurrence of electrical accidents; instead of compressed air system for hydraulic system, to avoid the pressure vessel, pipeline rupture caused by shock wave; with incombustible materials instead of combustible materials, to prevent the occurrence of fire. It should be noted that sometimes measures are taken to eliminate certain sources of danger, but new sources of danger may be brought about. For example, an electric pneumatic system instead of a power system can prevent electrical accidents, but a physical explosion accident may occur in the compressed air system.

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: Mechanical bearings, all types? Roughly: The basic structure and NU type cylindrical roller bearing inner ring bearing the same, but because of the needle, the volume can be reduced, and can bear large radial load to the bearing without inner ring shaft mounting surface with suitable precision and hardness is used as a raceway.

Q: What is the difference and connection between equipment manufacturing and machine building?: In accordance with the standards of classification, including metal products, general machinery manufacturing, machinery manufacturing, transportation equipment manufacturing, electronic and communication equipment manufacturing industry, electrical machinery and equipment manufacturing, instrumentation and office machinery manufacturing seven deducted 186 small consumer related manufacturing industry after class. Equivalent to the European countries referred to as "capital goods manufacturing", that is, we often say "the production of means of production industry."".
