Q: What are the sectors of machine building and parts processing?: Industry to classify, it is not very strict. For example, the insurance industry, mining, energy, food, hotels, real estate services industry, garment industry, advertising industry, aerospace, aviation, chemical, chemical, construction, health care, education, training, computer, metal smelting, fire, police, soldiers, accounting, beauty, body, media, publishing, wood, paper retail, wholesale, agriculture, tourism, justice, lawyers, sports, sports, arts, entertainment, medical, art, design, banking, finance, Internet, music, dance, postal, courier, transport, consulting services.

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: 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?: The purpose of setting up a mechanical pressurization air supply smoke prevention system is to provide evacuation routes and shelters without smoke interference in the event of a fire in the building. Therefore, in the closed door, pressing position, and the fire floor must maintain a certain pressure difference, the position of the air pressure value is a relative positive pressure); at the same time, in the open part of the pressure when the door can have enough air velocity in the opening section, to effectively prevent the intrusion of flue gas, the safety of personnel ensure evacuation and refuge.

Q: What are the mechanical drawing software?: The plane is mainly CAD and CAXA, there are some non mainstream mechanical engineer what, mainly engaged in your spare parts of machinery industry, roughness, form and position tolerance requirements, recommendations for CAXA, which symbols are readily available, there are standard parts library, mechanical symbols library etc..

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: What is a door rack for a construction site? How high is it generally?: Construction machinery network learned that the door scaffolding in our country production and use of time is not long, the scaffolding developed by the various research institutions, self-contained, and not common, varieties, specifications and diverse. Some factories copy foreign products and use the imperial size.

Q: Mechanical bearings, all types? Roughly: Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings. The center of curvature of the raceway of the outer race is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the axle and shell are bent, the axial load in two directions can be automatically adjusted. Radial load capacity, suitable for heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or the use of tight sets, the demolition cylinder installed on the cylindrical shaft. The cage uses a steel plate holder, a polyamide forming cage and a copper alloy car holder.

Q: What are the sub projects of a construction project?: Lime soil, sand and gravel foundation, geosynthetics foundation, fly ash foundation, dynamic compaction, foundation grouting, preloading foundation, vibroflotation foundation, jet grouting foundation, cement mixing pile foundation, soil and lime soil compaction pile foundation, cement fly ash gravel pile, cement soil pile foundation. Based on sand pile foundation

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
