In the process of vacuum
packaging machine long-term work possible fault types are many, the damage of different fault and severity is different also, but would not let us ignore.
And in its vertical cabinet equipment, because it is mainly for the powder product packaging, so also easy to cause a serious risk of dust explosion accidents, for this kind of failure, what preventive measures can we have?
dust explosion, refers to combustible dust within the scope of the explosion limit, in the heat source (
Open fire or high temperature)
Space, flame instantaneous spread to the whole mixed dust, chemical reaction speed, release a large amount of heat at the same time, the formation of high temperature and a lot of pressure, the energy of the system is converted into mechanical energy and light and heat radiation, has a strong destructive power.
It with aluminium powder, zinc powder, aluminum processing in more abrasive powder, all kinds of plastic powder, organic synthesis of pharmaceutical intermediates, wheat flour, sugar, wood chips, dye, bakelite ash powder, milk powder, tea, tobacco powder dust, coal dust, fiber and other places of the production and processing.
According to this characteristic,
explosion-proof equipment to meet customer demand for vacuum packing is very effective.
Therefore, should make it explosion-proof equipment of vacuum pump motor, use dust explosion-proof motor.
It refers to the shell design and manufacture according to the prescribed conditions, can prevent the dust into the motor shell, although not completely prevent dust to enter, but its into the quantity does not interfere with the safe operation of the motor, and internal dust accumulation is not easy to produce fire danger, when using, also won't cause around with explosive dust mixture explosion of the motor.
Its characteristic is:
(
1)
Shell has high sealing, in order to reduce or prevent dust into the enclosure, even to enter, it into the quantity also not form fire danger.
（
2)
Control the shell allows higher surface temperature does not exceed the prescribed temperature classes.
At present, has been used in food reserve of mechanized equipment.
Standard for GBl2476 dust explosion-proof electrical equipment.
1 -
90 'the dust explosive environment with explosion-proof electrical equipment'.
the place on put together is narrated, vacuum
packaging machine to prevent the occurrence of dust explosion, well should choose to have explosion-proof performance of dust explosion-proof motor, so even if its internal appear dust accumulation is also won't appear the explosion danger, I hope you can know.
