Governor
A governor, or speed limiter or controller, is a device used to
measure and regulate the speed of a machine, such as an engine.
Machines Applicable:
We provide governor for basically all high speed packing machines
while the one in photos is for GDX2 cigarette packer.
Function:
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:
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. 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 frequencies.
Mechanism:
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
frequencies.
In practice, the droop curves that are used by generators on large
electrical grids are not necessarily linear or the same, and may be
adjusted by operators. This permits the ratio of power used to vary
depending on load, so for example, base load generators will
generate a larger proportion at low demand. Stability requires that
over the operating frequency range the power output is a
monotonically decreasing function of frequency.
Customization:
Electromagnetic clutch shown in pictures are for Molins Mark8
cigarette making machines. Please provide detailed info. to us if
your desired specs is different.
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.
Shipping Terms:
Preferred: EXW, FOB, CIF, CFR
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 our own.
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.
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.
Payment Terms:
For regular size wear parts/ consumables/ spares, normally we
request 30% payment before sending order to our plant, and the
balance before shipment.
Payment terms are negotiable under following principles:
For products we have in stock, normally we ask for full payment
upon ordering.
For products of customized specification, or painted as required,
or of special materials, normally we ask for full payment upon
ordering.
