The use of laboratory air-purifying fume hoods is not only properly designed, but also has a lot to do with proper use and maintenance. Therefore, the following points should be noted:
(1) In the course of the experiment, the experimental device for generating harmful substances shall be placed at a place where the operating port of the cabinet of the clean gas type fume hood is greater than 150 MM to prevent the spillage of harmful substances;
(2) The experimental device of the clean air fume hood should not block the exhaust vent;
(3) After the experiment is completed, the fan should not be turned off immediately, and it takes 3 to 5 minutes to turn off;
(4) The net air type wind cabinet should not be used as a storage cabinet;
(5) The interior of the clean air fume hood should always keep the inner surface of the cabinet clean and sealed. It should be thoroughly cleaned and cleaned regularly. If it is damaged, it must be repaired in time;
(6) Fans, ducts and related accessories shall be regularly inspected.
(7) At intervals, the fume hood shall be measured and adjusted once; the clean air fume hood shall be operated under design conditions;
(8) The temperature inside the clean air fume hood, such as the electric slab with a large wattage, should be placed on the block, so it should not be stored for a long time to avoid affecting the use of the ventilating fume hood.
Jumbo Underground Drill Rig
The drilling jumbo rig is the main drilling equipment in the underground hard rock mine.
Manipulator drilling rig with high level of automation and computerization is not very attractive to mine.
The mine hopes to use the trolley with compact structure, flexible movement, high reliability, high efficiency and high accuracy.
Small enough to enter the shaft through a small section;
Maneuverable and flexible enough to walk in winding and inclined passages;
The versatility can be used to drill hole, bolt hole and cut hole in all directions.
In recent years, several major rock drilling equipment manufacturers in the world, in order to meet the requirements of mechanized mining of thin ore bodies, have successively developed a variety of small rock drills with high power, which can be used to complete the rock drilling operations that could only be completed by pneumatic drill, so as to significantly improve the efficiency of rock drilling and reduce ore dilution rate.
