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.
The one in photos is for GDX2 cigarette packer.
Function:
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:
It works by controlling the rate of power produced by the prime
mover according to the grid frequency. 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.
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.
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
It is 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
our own.
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.
Note:
Larger orders always get better prices.
Most products can be customized, please contact with us for any
specifications needed but not listed on our website.
For wear parts/ consumables/ spares made of metals, material is
often optional. Normally choices of our client varies from steel to
alloy, depending on capacity of the machine to be applied to.
Please also let us know before shipment if you need extra insurance
for freight.
