1.5 GENERAL NOTES ON DELIVERY
Upon delivery, please check that the number of packages matches what reported
in the delivery note:
- ROTOMEC hydromechanical coupling
- Use and maintenance handbook (Original Instructions)
- Warning plate kit
- Over heating control devices (TF,TE,PM+T09)
- Accessories (if any)
Please also check what follows:
1- the parcel is intact,
2- shipping data (consignee’s address, number of parcels, order no.) matches
the order and the goods delivery note.
3- the delivered objects are not damaged.
Should any of the parts be damaged or missing, please inform immediately
(within 8 days from receipt) the manufacturer or the local distributors or
agents, the forwarding agent and/or the insurance company providing details
(photographs, if needed).
The operator in charge of the maintenance must conveniently store the
supplied materials under shelter, in a dry and safe place, not accessible
to unauthorized personnel.
1.6 HYDROMECHANICAL COUPLING DESCRIPTION
The ROTOMEC constant filling hydromechanical coupling consists of two
impellers opposite to each other, one connected to the motor shaft or motor
part, called pump, and the other connected to the machine or driven part, called
turbine.
The pump and the turbine are not connected to each other and the transmission
of motion and the torque in absence of usury, through a suitable transmission
fluid, with which the hydromechanical coupling is filled.
The mechanical power supplied by the motor or motor part, to which the cou-
pling pump is connected, is transformed into hydrodynamical energy of the
transmission fluid (inside the coupling) that, in contact with the opposite turbine,
it is again converted into mechanical energy, with the progressive transmission
of the torque to the driven part.
On the opposite side of the pump (between the pump and the cover) there is a
centrifugal coupling, consisting of four centrifugal masses with wear-resistant
rollers that grip radially on the external ring of the pump, allowing the residual
sliding to be neutralized, giving a power transmission and rotation efficiency of
100%.
The operating principle of the transmission torque of the ROTOMEC coupling
provides for a series of important advantages for the mechanical protection of
transmission elements: soft starts, a remarkable reduction in power and energy
consumption on start-up as well as an important protection against overload at
full capacity.
