CMH designed and built a hydraulic power unit for an industrial application in the leather goods sector and fine leather processing.
In this production field, machines must combine force, control and smooth operation, adapting to processes in which the quality of the final work is of fundamental importance.
The power unit was developed to measure, according to the characteristics of the machine and the performance required by the process.
The main characteristics of the unit are:
This is therefore a power unit with a significant installed power, engineered to drive an industrial application dedicated to leather processing.
Industrial leather processing covers numerous processes and specialised machines.
In some applications, the use of hydraulics makes it possible to develop high forces and manage controlled movements through compact, reliable systems.
Correct sizing of the unit must take into account the real requirements of the machine: power demand, flow rate, duty cycle, actuator characteristics and thermal management of the system.
For this reason CMH does not start from a standard power unit, but from the function the system has to perform.
The motor-pump group is the heart of the hydraulic power unit.
In this application the 37 kW electric motor drives a pump with a displacement of 56 cc/rev, a configuration defined according to the operating requirements of the machine.
It is important to distinguish the displacement of the pump from its effective flow rate: the latter also depends on the rotation speed and on the real operating conditions of the system.
The unit uses a 250-litre reservoir, sized as an integral part of the entire hydraulic system.
The reservoir does not only contain the oil: it also contributes to correct fluid management, heat dissipation, air separation and the settling of any contaminants.
Its sizing must therefore be assessed together with the overall characteristics of the system and the work cycle of the machine.
Every production sector has different requirements.
Whether the field is leather goods, metallurgy, construction, automation or handling, the CMH design principle remains the same: analyse the work required of the machine and build the most suitable hydraulic solution around it.
Motor, pump, reservoir, valves, filtration, control and thermal management are selected and sized as parts of a single system.
The objective is a reliable hydraulic power unit, easy to integrate into the machine and consistent with the expected operating conditions.
This unit for the fine leather processing sector, with a 37 kW motor, a 56 cc/rev pump and a 250-litre reservoir, is a concrete example of that approach.
Designed. Built. Tested in Italy.
