What is the 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. About 80 percent of the chemicals in industrial production are explosive.

Oxygen: oxygen is everywhere in the air.

(1) explosive substances: substances that react with oxygen (air), including gases, liquids and solids. (gas: hydrogen, acetylene, methane, etc.; liquid: alcohol, gasoline; solid: dust, fiber dust, 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.

 Structure of vibration motor

(2) the bearing is a cylindrical roller bearing with a detachable inner shell. The bearing should be placed on the rotating shaft in parallel;

(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;

(4) the inner and outer eccentric blocks are installed on the rotating shaft in parallel. If there is an eccentric key slot on the shaft, the rotary key block is inserted into the shaft to fix it together with the shaft;

(5) before unloading, tighten the fastening bolt of eccentric block, turn the adjustable eccentric block to the angle position and tighten the fastening bolt. The axial movement of the shaft after the above assembly is completed;

(6) the protective covers at both ends of the upper vibration motor are fixed with screws.

Laboratory vibrating screen is mainly used for standard sample sieve instead of manual sieve, which has the advantages of time standard, high strength and frequency.
