Depending on the emergency, our staff can arrive on your site as soon as possible. We intervene under an average work duration of 24 hours.

 

NCG is able to retrieve your obsolete equipment for recycling.

NCG integrates technical solutions (products, modernisation projects, etc.) in favour of the environment into each service.

These solutions allow you, thanks to our latest generation and refurbished product range as well as our advice on optimising the speed regulation loop, to improve environmental performance (energy, limitation of black smoke, etc.)

Our project team and our QSSES manager are at your service for further information.

In case of emergency, contact our hotline 24/7 : +33(0) 771 913 256

Replacing an old command and control system with a new generation equipment has many advantages, particularly in terms of reliability, speed of response, accuracy of settings and reduced maintenance costs.

CONCERNING THE DOCUMENTATION TO BE PROVIDED

The required documents are as follows:

A detailed report containing:

  • Photographs of the governor on receipt
  • Parts that require replacement and the reason for replacing them
  •  Photographs of the governor in its final state
  • The test curves on receipt and at the final state
  • The manufacturer’s test sheet in its initial and final state
  • A delivery note summarizing the P/N and S/N of the equipment

Feel free to visit the product sheet section to learn more about our speed control equipment.

CONCERNING MY EQUIPMENT

The identification of these codes can be found on the nameplate on the governor body.

  • The part number defines the type of equipment
  • The serial number is the single incremental number of the equipment
  • These are precise identifications of the type of equipment you own
  • It also allows you to know the functionalities of your equipment
  • Hydraulic-Mechanics
  • Electronics

The adjustment of a controller requires perfect knowledge of its functions.

Some adjustments can be made by the end user if he knows the procedure to be performed and the risks.

For warranty reasons, internal adjustments to the equipment are only possible by persons authorised by the manufacturers.

The obsolescence of equipment is generally due to the interruption of parts’ manufacture. To learn more about the obsolescence of Woodward brand equipment, read our article on our modernization recommendations.

CONCERNING TECHNICAL REFERENCES

  • This varies greatly depending on the operating mode of the governor (main engine or generator set) and temperatures. It is necessary to count one oil change every 3,000 or 4,000 hours.

For more information, please refer to the Woodward Oils For Hydraulic Controls Guide

The degree of wear and tear as well as the condition of each part

NCG recommends that equipment maintenance be performed every 3 months or 15,000 hours of operation.

It also depends on several factors:

– the type of governor

– the maintenance performed

– its environment

– the frequency of use



ALL ABOUT SPEED CONTROL

Speed control makes it possible to control the quantity of driving energy admitted by a machine according to its environment (setpoint, load, pressure, etc.).

A governor is an equipment that controls the driving energy of a machine according to the set point applied to it. The actuator will carry out the action requested of it by its control signal but has no information on the setpoint. The actuator is generally associated with an electronic governor.

A booster is a starting aid device making it possible to overcome, at this precise moment, the absence of oil pressure in the governor.

We recommend you to send us your booster at the same time as your governor for a complete and optimal refurbishment. Read our article about it to know the interest and the importance of its overhaul.
