Electric Generator Governor For Droop Speed Regulating On Super Slim Cigarette Packer

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.

Other Applications - Small Engines

In the case of generator applications, the engine speed must be closely controlled so the output frequency of the generator will remain reasonably constant. Small engines, used to power lawn mowers, portable generators, and lawn and garden tractors, are equipped with a governor to limit fuel to the engine to a maximum safe speed when unloaded and to maintain a relatively constant speed despite changes in loading. 

Machines Applicable:

We provide governor for basically all high speed packing machines while 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:

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. 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. It works by controlling the rate of power produced by the prime mover according to the grid frequency.

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.

Shipping Terms:

Preferred: EXW, FOB, CIF, CFR

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.

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 our own.

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.
