What is the hidden danger of vibration motor explosion?

Vibration motor What are the hidden dangers of explosion?
 
 
 
Ignition source of vibration motor: a large number of electronic instruments are used in the production process. All kinds of friction sparks, mechanical wear sparks, electrostatic sparks, high temperature and so on are inevitable, especially when the instrument or electrical failure occurs. It is said that many industrial sites meet the objective conditions. When the mixed concentration of explosive substances and oxygen is within the explosion limit, if there is an explosion source, the explosion will occur. Therefore, it is necessary to take explosion-proof measures. Explosive substances: many production sites produce many flammable substances. About two thirds of coal mines contain explosive substances. In the chemical industry, about 80% of the production plants contain explosive substances.
 
 
 
Oxygen is everywhere: air.
(1) explosive substances: substances that react with oxygen (air), including gases, liquids and solids. (dust, gas, etc.; gas: gas, gas, etc.)
(2) air or oxygen.
(3) ignition source: including open fire, electric spark, mechanical spark, electrostatic spark, high temperature, chemical reaction, light energy, etc.
 
 
 
Replace the bearing motor with a new one and use the same bearing as the original model.
(1) clean the bearing with kerosene, press it into the bearing housing, fill the roller of the bearing outer ring with shell No.3 lithium grease until it is two-thirds full, apply it evenly with a mesh hand, install the bearing cover, and press the coated bolt with anti-skid rubber fastening bolt on the bearing cover
(2) the bearing is a cylindrical roller bearing with a detachable inner shell. The bearing should be placed on the rotating shaft and in position;
(3) install the bearing housing on the housing. If there are grease holes, align them. Press the bearing seat with the fastening bolt of anti loose rubber;
And install the eccentric block on the inner and outer shaft. If there is a shaft key, insert the key shaft into the keyway, then install the external eccentric block, and install the shaft and the fixed ring on the rotating shaft together;
(5) before unloading, tighten the fastening bolt of eccentric block, turn the adjustable eccentric block to the angle position and tighten the fastening bolt. After the above assembly, the shaft should move in the axial direction;
(6) the protective covers at both ends of the upper vibration motor are fixed with screws.
