In mining (such as large ball mills, vibrating screens, ball mills, sorters, rod mills, etc.) in tungsten mines, the wear and tear of large and medium-sized industrial equipment is high, resulting in depreciation of fixed capital machinery and equipment and excessive consumption of driving force resources. It increases the product cost to a great extent. Therefore, the lubrication phenomenon of the automatic lubrication system of industrial equipment is an important phenomenon faced during the use of mechanical equipment. It is also an important factor in extending the service life of mechanical equipment, controlling costs, and increasing productivity. Reasonable assurance.
Due to the large number of lubrication points, high temperature of the equipment, dustiness and other factors, it is often the case that there is no oil at the lubrication points and there is less oil. For important lubrication points, if there is too little oil, the equipment will be seriously damaged, or even Shutdown may lead to work stoppage. Therefore, it is extremely important to promote a reliable, efficient and flexible lubrication technology on large mining equipment.
The traditional centralized air intake system has many shortcomings, such as: the system is loose, slow to upgrade, and cannot adapt to the development trend of industrial equipment; the amount of oil required is often determined based on people's feelings and experience. Distribution, rather than doing their best, often results in excessive lubrication and insufficient lubrication; dry oil lubrication and sprayer surge lubrication are implemented separately, increasing product costs; most working status detection equipment such as temperature alarms are separate and scattered ized, must be inspected manually.
To address the above shortcomings, a type of automatic air intake system was designed.
On the basis of the current traditional air intake system, the oil provided is specified and quantitatively analyzed, and the two lubrication methods of gear oil pump and bearing grease injection are combined. Through the fully automatic intelligent air intake system, the large and medium-sized mining industry can be realized Remote operation of equipment lubrication. Use upper PC and PLC, upper and lower microcontrollers to design separate functional characteristics to realize the supervision of technical parameters such as remaining oil at each lubrication point, lubrication cycle time and critical pressure value, and At the same time, the communication between the upper and lower microcontrollers is used to make the lower computer make a sound to feedback the information of the fault lubrication point. In addition, the upper and lower microcontrollers can also perform actions based on the information sent out by the PLC. , it can also start automatically without changing the command. The remaining oil and lubrication cycle time can be changed according to computer remote control, or it can be designed and set by the main control chip cabinet or upper and lower microcontrollers.
This automatic lubrication system can replace manual lubrication work with low labor productivity in the lubrication of industrial equipment in large and medium-sized mineral processing plants. At the same time, it improves the efficiency of industrial equipment application and has corresponding social and economic benefits.
