Hydraulic Units
Economy and easy implantation
Hydraulic units include several devices, such as oil tanks, displacement pumps, directional valves, retention valves and actuators. They are arranged in logic circuits to enable the movement and control of a certain machine by means of fluid displacement, performed by one or more sets of electric motors and hydraulic pumps.
Due to their simple operation, hydraulic drives are used in many different applications, such as presses, thermoforming machines, truck dumpers, injection molding machines and calenders.
It is worth of notice that in this kind of application, when no movement is needed, both the hydraulic pump and the electric motor keep running at rated speed with the hydraulic fluid circulating, resulting in waste of electric energy and unnecessary oil heating. On the other hand, turning off the electric motor may cause damages such as the equipment burn out due to successive starts and excessive mechanical wear of the oil pump.
Benefícios reais da aplicação
- Economia de energia elétrica de até 60%
- Fácil implantação com poucos impactos no sistema de produção e na máquina de injeção
- Replicável a outros sistemas hidráulicos, como prensas, tombadores de caminhão, injetoras de alumínio, etc.
- Redução da temperatura do fluido hidráulico e consequente menor desgaste dos componentes hidráulicos
