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 - Mopeds

Mopeds in the United Kingdom have had to have a 30 mph (48 km/h) speed limiter since 1977. Most other European countries have similar rules.

Urban public buses often have speed governors which are typically set to between 65 kilometres per hour (40 mph) and 100 kilometres per hour (62 mph).

Public service vehicles often have a legislated top speed. Scheduled coach services in the United kingdom (and also bus services) are limited to 65 mph.

Other Applications - Public services vehicles

Machines Applicable:

We provide governor for basically all high speed packing machines and the one in the 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. 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. 

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.With droop speed control those systems will remove energy from the grid at higher than average frequencies, and supply it at lower frequencies.

Droop speed control can also be used by grid storage systems. 

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.

Payment Terms:

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.

For regular size wear parts/ consumables/ spares, normally we request 30% payment before sending order to our plant, and the balance before shipment.
