Q:What is a door rack for a construction site? How high is it generally?
Door scaffolding has not yet unified design and product standards, the products of different specifications, quality is inconsistent. Not only for construction units to use and management of great difficulties, is not conducive to the promotion of applications, but also to the construction safety risks. Therefore, it is necessary to organize and issue a unified standard for door scaffolding
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 kind of electrical equipment do you have? What are the main components of each device?
The utility model relates to a distribution box, belonging to a primary equipment in an electric equipment. Electrical equipment includes primary equipment and two equipment.

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:How are the machine parts stacked?
Then there is a point to note, that is, from there to get used, must be put back where, so that will be organized, all things are owned by you, it will not mess.
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
