Governor
A governor, also named as speed limiter or controller, is a device
used to sense and control the speed of a machine, such as an
engine.
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.
Other Applications - Elevator
Governors are used in Elevators also. It acts as a stopping
mechanism so that the elevator does not run beyond its tripping
speed (which is usually a factor of the maximum speed of the lift
and is preset by the manufacturer as per the international lift
safety guidelines. This device must be installed in traction
elevators and roped hydraulic engine elevators.
Machines Applicable:
We provide governor for basically all high speed cigarette packing
machines while the one in photos is for GDX2 cigarette packer.
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. 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
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.
Mechanism:
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.
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.

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.
