Chap.5 - Cleaning/Maintenance
a) Cleaning
The generator cleaning and checking fluid levels are the only periodic maintenance required. No
additional maintenance should be necessary if all instructions are followed.
We recommend a complete overhaul of the unite every 2 years. This operation can only be
performed by the manufacturer. If necessary, send us your device for maintenance. A complete
assessment of your device will be made and an estimate of rehabilitation will be sent.
Instructions reminders :
- Use only oil H40 or H15 or Sebacate (depending on model).The guarantees of performance and
operation are insured with the use of these oils.
> wear are protection : protects the eyes
against splashes and projections of the
fluid.
- Don't remove the protective cover.
NOTES : For comparators without isolation valves
A'
, the capacity of the pumps 60 cm3 may be
insufficient to fully complete a high volume measuring device. In this case, a solution with
intermediate valve is possible by interposing it between the bench and the device. We repeat the
cycle as many times as necessary. For these applications, a specific kit can be supplied.
It can also fill in advance before mounting the pressure generator.
b) Maintenance
> Piezometric set
It's designed for extremely narrow limits of accuracy. It's forbidden to disassemble it.
> Valves
Generator and dead weight are equipped with instrumentation valves, it's imperative to observe
the following guidelines :
- Maximum torque applicable abutment valve open = 0,3 Nm
- Maximum torque applicable abutment valve closed = 4 Nm.
When the abutment valve open is reached, turn the wheel valve 1/4 turn clockwise.
> Tank oil
Make sure the tank contains enough liquid to make the required calibrations. If necessary, fill the
tank with the same liquid as that already used. Don't mix different types or brands of fluids into
the generator and use the recommended oil.
Skydrol, solvents may damage the o-rings mounted on a generator.
Keep clean bench, wipe traces of fluid, and particularly the oil condition in the tank to detect
traces of pollution. If the fluid in the system is dirty, drain the device and remove dirty oil.
