Dust Removal Mist Cannon Machine,Principles and
Starting Modes
The dust removal mist cannon machine
operates on the principle of air delivery.
It utilizes an imported high-pressure
pump and a fine atomizing nozzle to
atomize water.This atomized water mist
is then propelled over long distances
by the fan's air volume and pressure,
allowing the mist to cover larger areas.
As the water mist condenses and falls,
it binds with dust particles,effectively
reducing dust levels.
Starting Modes of Dust Removal Fog Cannon Machine
1.Direct Start:
Suitable For:Motors with power ≤ 11kW (also known
as full voltage start).
Advantages:Low investment cost,simple structure,
and easy maintenance.
Disadvantages:Large starting current and significant
impact on the power grid.When using a fuel generator,
it requires a large generator capacity.Frequent starts
can reduce the service life of electrical equipment due
to high current impact.
2.Star-Delta Start:
Suitable For:Starting three-phase asynchronous
motors with a connection during normal operation.
Advantages:Starting current is 1/3 of direct starting,
less impact on the grid,simpler structure,and lower
cost than other step-down starting methods.
Disadvantages:Less effective for very high-power
motors.
3.Soft Start:
Suitable For:Motors with power ≥ 45kW.
Advantages:Offers multiple starting modes,various
protections (phase loss,overload,over current,over
temperature),small starting torque,minimal impact
on the power grid,and extends equipment service life.
Disadvantages:Higher cost,potential harmonic
interference,and increased failure rate of the thyristor
during power grid fluctuations.Maintenance and
repair require professional technicians.
4.Inverter Start:
Suitable For:Applications requiring speed control.
Advantages:Adjustable motor speed and torque
through changing output power frequency.Provides
smooth starts,comprehensive control functions,
minimal grid impact,and is ideal for fuel generator
power supply or unstable grid systems.
Disadvantages:Large size,high cost,frequency
interference,and complex internal structure.
Maintenance and repairs require professional
technicians.
By understanding the various starting modes and
their advantages and disadvantages,users can
choose the best starting method for their specific
application,ensuring optimal performance and
longevity of their dust removal mist cannon
