2. The mining of Meiyukou mine has a long history. As early as 1929, there was a record of pit opening. After the founding of the people's Republic of China, the mine construction and mining technology have entered a benign development track, belonging to the double period coal mine. At present, the mining is Jurassic coal series, and the comprehensive mechanization and tunneling loading mechanization degree of the mine reaches 100%. The coal belongs to weak caking coal. The coal proct has the characteristics of low sulfur, low ash and high heat, and is high-quality steam coal. There are five types of coal: big, medium, big end, big friend, big friend 1. Procts are widely used in chemical instry, metallurgy, building materials, electric power and other instries, exported to Japan, South Korea, India, Turkey and other countries
in recent years, Meiyukou Coal Mine adheres to the scientific development concept of people-oriented, establishes the business philosophy of "enterprise is my family, the first is the enterprise" and "everyone is careful, everyone is in charge of financial management", takes the coal quality as the cornerstone for the survival and development of the enterprise, relies on science and technology and talents as the driving force for the development of the enterprise, and comprehensively implements the strategy of strengthening the enterprise with science and technology and revitalizing the mine with talents, By introcing new procts, new technologies, new processes and new equipment, taking the road of sustainable development, strengthening technical cooperation and exchanges with international counterparts, continuously improving the quality of coal procts and enterprise competitiveness, mine management, technical equipment, output and efficiency have been steadily improved. The company has won the honorary titles of national "first class coal enterprise", national "advanced unit of coal field management", national "quality standardized mine", Shanxi Province "civilized unit of provincial management of state-owned enterprises", Shanxi Province "AAA level labor security integrity enterprise".

5. To wash your feet, this is very normal, now all go to wash your feet, as long as there is a little money. They all went. Now the busiest thing is the foot washing room, where rows of people wash their feet. There is no doubt about this
you feel uncomfortable. What's wrong with you. If there are other situations, if there are other situations, it must be impossible. You can ask other people, indirectly, not directly. I don't know the specific situation yet.

6. Direct calculation needs a lot of detailed data
if it is a measurement, it is very simple
pull the trolley with a spring dynamometer, observe the change of indication, and record the reading when the trolley starts to move.

7. Under the premise of correct assembly, the ball screw only bears the axial load, which is transferred to the bearing seat through the bearing in the nut seat, and then to the machine base. The factors of axial force of lead screw are as follows:

1) in horizontal operation, the friction force of guide rail Fmax = u * m * G + m * Amax, in vertical operation, the handling weight Fmax = m * G + m * Amax, where Fmax is the maximum force (unit n) formed by the mass of worktable and moving parts, m on the lead screw, u is the friction coefficient of guide rail, and G is the acceleration of gravity (unit M / S ^ 2), Amax is the maximum acceleration when moving (unit: M / S ^ 2), and M is the maximum mass of worktable and workpiece (unit: kg)
2) there is no fixed formula for the size of external force (such as cutting force), so the calculation formula should be obtained after consulting the metal processing manual or analysis according to the situation
3) the axial internal preload of the ball nut is generally 5% to 30% of the rated dynamic load of the ball screw, and it is zero without preload. The rated dynamic load should be checked on the sample of the screw manufacturer
as for the stress analysis of the guide rail, the stress analysis can only be done according to the layout of the guide rail and the principle of torque

you can refer to the comprehensive explanation of rolling linear guide pair and ball screw pair design in Shenzhen sired sample. Go to the official website to download the samples.

9. If the pointer falls out, take it to the watch repair shop for the master to help you disassemble it and install it back. By the way, check whether there are loose parts in the movement, because the movement will be vibrated ring the fall of the watch, which may cause the internal parts to loosen or fall off, thus causing the watch to stop
watch knock: because the watch is exposed most of the time ring wearing, it is easy to knock other hard objects when walking., If you accidentally knock or fall on the watch in daily use, it may lead to the movement gear and other parts of the watch loose, dislocation and other situations, which will also lead to the mechanical watch to stop stealthily
you can take it to Guangcheng watch shop on the first floor of 325 Beijing Road for inspection and maintenance.

10. Can directly find customer service, let them show you the specific problem. They are online for 7 * 24 hours, and they reply very quickly.
