A governor, or speed limiter or controller, is a device used to
measure and regulate the speed of a machine, such as an engine.
We provide governor for basically all high speed packing machines
while the one in photos is for GDX2 cigarette packer.
Electrical generator - droop speed control
For electrical generation on synchronous electrical grids prime
mover's drive electrical generators which are electrically coupled
to any other generators on the grid. With droop speed control, the
frequency of the entire grid determines the fuel delivered to each
generator, so that if the grid runs faster, the fuel is reduced to
each generator by its governor to limit the speed.
Droop speed control:
With droop speed control, when the grid is operating at maximum
operating frequency, the prime mover's power is reduced to zero,
and when the grid is at minimum operating frequency, the power is
set to 100%, and intermediate values at other operating
Droop speed control is a control mode used for AC electrical power
generators, whereby the power output of a generator reduces as the
line frequency increases. It is commonly used as the speed control
mode of the governor of a prime mover driving a synchronous
generator connected to an electrical grid. It works by controlling
the rate of power produced by the prime mover according to the grid
Droop speed control can also be used by grid storage systems. With
droop speed control those systems will remove energy from the grid
at higher than average frequencies, and supply it at lower
Depending on machine models and other factors, time needed for
manufacturing can vary. Thus details of product and relative lead
time must be negotiated beforehand to avoid any discordance.
It had always been our first priority to provide quotation with EXW
terms applied price. Still for final shipment the other 3 sets of
shipping terms are most recommended. We would like to have the
export clearance process done by ourselves since normally we know
China’s customs more than our clients do. Also the tax rebate
procedure can be more or less simplified if we clear the custom on
For any other sets of shipping terms especially those where export
clearance is no more our obligation to see to, please contact with
us for further detail negotiation, so as to avoid any discordance.
We provide on-site engineering support for installation of complete
machines if requested.
For requirement of specific certification to meet import
regulations of certain nations, inform us beforehand to get our
products certified if they are not yet.
