Q:To ask, I have better supply of construction machinery here, I would like to foreign trade, I do not know how the international market in the near future, engineering machinery, foreign trade to prepare what knowledge?
Unexpected debt crisis in Europe is likely to enter the global financial crisis of second act "-- before the international financial predators Soros made such a point of view. For the Chinese enterprises, the export situation in the coming months seems to be very dense. Construction machinery industry exports suffered a severe blow in the financial crisis. In 2010, the export situation is still the key factor restricting the growth of the industry.
Q:What subjects are specialized in mechanical manufacturing in secondary schools?
[] [mechanical drawing machine design foundation [] [] engineering mechanical hydraulic and hydraulic transmission] [] "mechanical manufacturing technology of NC machining materials" "special processing" technology is still the main focuses on the operation, so there will be a variety of training etc.
Q:Classification of materials in machinery industry
Belonging to inorganic materials are refractory, ceramics, abrasives, carbon and graphite materials, asbestos and other organic materials; it is wood, leather, adhesive and synthetic polymer materials, synthetic rubber, synthetic resin, synthetic fiber etc.; the reinforced composite material composed of resin matrix with non metallic fiber.
Q:About the marketing strategy of construction machinery industry
The art of war said, "those who do not seek the overall situation, can not seek a domain, do not seek a domain, can not seek the overall situation", and emphasizes the importance of the thoroughness of strategic activities. The thoroughness of marketing planning mainly comes from the detailed knowledge of the market, the ability of insight into the market and the rich planning experience. The action plan should be practical, operational and flexible
Q:Can you use mechanical oil instead of engineering gear oil?
The second category is the mechanical oil (including high-speed mechanical oil). Machinery oil and heavy machinery oil, mainly used in textiles, sewing machines and lathes, etc., and its main function is also lubrication.
Q:Please tell me the highest and lowest price of Xugong machinery
The highest price of Xugong is 64.7 yuan, the lowest price is 1.81 yuan. Xugong Group was founded in March 1989, 25 years to remain Chinese engineering machinery industry pacesetter status, the construction machinery industry in the world top 500 enterprises in fifth, China 150th, China manufacturing 500 fifty-fifth, is a large group Chinese engineering machinery industry is the largest, product variety and series of the most complete, the most competitive and influential.
Q:Steel for construction machinery, including those concrete materials?
Construction machinery is a general term for construction machinery used in engineering construction. Widely used in construction, water conservancy, electricity, roads, mines, ports and national defense and other fields of engineering, a wide range of. When mechanical equipment is running, some parts of it can even carry out mechanical movement in different forms.
Q:What is the difference between the application and maintenance of construction machinery and the operation and maintenance of automobiles? What a promising future!
There are many kinds of equipment for construction machinery, which are basically related to complicated hydraulic components. More and more advanced equipment, the use of electrical computer technology even more complex than the car. The EFI, HEV and other technical engineering machines used in automobiles are also developing vigorously
Q:How much money do you need to invest in construction machinery parts?
CD-ROM is best to use Samsung's DVD engraved, ASUS's noise is quite large oh. With the background of case 8185B, a power supply for the mute. Display is best to use NESO's Dragon tube, do map, that is, to an effect.
Q:Please tell me how to use the multimeter to measure those aspects when the working circuit of construction machinery is out of order
Construction machinery movement, the executing agencies have cylinder action (hydraulic), motor and so on. Control parts are mostly weak current, drive parts and actuators are strong electricity (such as motor). When work is out of order. Generally check the power supply, the boot after the drive part of the power.
