Q:What are the principles, performances and uses of the commonly used construction machinery equipment?
1.: concrete pump principle: concrete pump driven by motor pump system, the conveying capacity of constant power control of hydraulic system of concrete pump automatic control, manual control can also be used to select the concrete delivery volume. Performance: 1. using the hydraulic system of double pump double open circuit, the main pump valve swing circuit and S circuit are separate for fault diagnosis and removal; 2. pumping hydraulic circuit adopts the main valve pilot pressure control; 3. hydraulic system has safe relief protection, while the main pumping system overpressure, oil pump automatic pressure cutting off; 4. switching circuit with constant voltage supply with the energy storage device, so as to guarantee reliable swayingforce large and have the advantages of energy saving effect; 5. pumps and valves are used continuously, the world famous brand is more reasonable and more reliable and easily realized commodity concrete transport quantity adjustment; 6. hydraulic pipeline with cone seal pipe joint sealing material; 7. pumping circuit adopts a valve block mode of high and low voltage switch, convenient, no leakage; 8. with oil and oil filter technology, foreign body into the hydraulic system. Further improve the hydraulic system reliability and component life; 9. hydraulic hose hose. Use: widely used in commercial concrete demand for large, high grade and strict quality requirements, long conveying distance of high-rise buildings, municipal construction, electric power, energy, transportation and other civil and industrial buildings, especially the construction of the narrow space more show its true colour of a hero.
Q:What is the use of spare parts prices in Chinese market by foreign companies?
You might be gathering information for him. You have no data for one person, if there are several people? They can analyze a lot of things through big data. You can't find out, you're OK. Once you find out, your whole life is over.
Q:What are the sub projects of a construction project?
Appendix B Construction Engineering Division (sub branch) engineering, sub project division, B.0.1 Construction Engineering Division (sub branch), engineering, sub projects can be divided into table B.0.1. Table B.0.1 division number of construction works, sub works and sub projects
Q:Building materials, equipment, components and fittings products must have "three certificates" is what cards?
Product qualification certificate means the qualified certificate, qualified label or qualified seal issued by the manufacturer to indicate the quality of the products manufactured by the factory and qualified on the package of the product or product. This is the producer's guarantee of the quality of its products, and also the obligation of a product to be stipulated by the law.
Q:What kind of electrical equipment do you have? What are the main components of each device?
Electrical equipment, electrical parts, electrical equipment, electrical components: mainly refers to other construction equipment matching, power driven, electrical heating, electrical lighting, and other direct consumption of electricity and into other parts of energy. Such as: motor and electric heater and start control equipment, decorative lighting lamps and the switch socket, television communication and intelligent engineering for power supply and transformation or environmental protection dust and kitchen fume and other special DC power supply etc.
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.
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:Where was the construction machinery conference held in 2015?
Support unit: Automobile and engineering machinery parts testing institute, Qihe Economic Development Zone, Shandong Province, Shandong Jiaotong University, Mechanical Engineering Institute, Qingzhou Engineering Machinery Industry Association, three, China Railway ten Bureau, in a company, China water conservancy and hydropower Sixth Engineering Bureau Co., Shandong high speed group limited company, the China Metallurgical Construction Group Limited, China Railway Construction Group, Shandong road fourteen, Shandong the Yellow River Engineering Bureau Group Co. Ltd., Ji'nan City Highway Bureau, Dezhou City Highway Bureau, Tai'an City Highway Bureau, Jining City Highway Bureau, Laiwu City Highway Bureau, Shandong WorldCom Highway Construction Co. Ltd.
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: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.
