Hydraulique

MAPAL propose des processus d'usinage complets et sur mesure pour les composants fonctionnels des circuits de commande et de direction hydrauliques mobiles. Par ailleurs, les solutions de processus innovantes qui créent de la valeur sont appréciées dans la fabrication de composants issus de l'hydraulique stationnaire.

(1) Hydraulic valve housing: Machining solutions for hydraulic valve housing

Everything depends on the main bore. Manufacturing valve housings
is the supreme discipline in the world of fluid power. For years, MAPAL’s
expertise has been in demand for the spool bore. The gap dimension
with the spool depends on the accuracy of this bore, so that the
hydraulic oil can only flow in the required direction without
leaking. This is very narrowly defined in modern hydraulic
valves. The roundness, cylindrical form, straightness
and surface finish of this bore are therefore crucial.

Basic procedure – analysis of the machining process

As technology partner, MAPAL supports customers with regard to complete process design. The experts pay particular attention to the cost drivers here, which can often be found in the function-relevant bores. Based on the respective honing procedure, the part requirements and lot sizes, MAPAL designs the perfect machining strategy in dialogue with the customers.
One objective unites all activities: designing the most economic process, starting with piloting, boring and semi-finish machining up to the efficient honing process.
(2) Control block: Control block

The hydraulic control block connects diverse valves and control components. These are installed in or mounted on the control block, which acts as a control and distributing system in hydraulic circuits.

(3) Axial piston pump: Axial piston pump

Axial piston pumps and motors together are referred to as axial piston machines. An axial piston pump transforms mechanical energy into hydraulic energy and an axial piston motor transforms hydraulic energy into mechanical energy.
Axial piston machines are characterised by a high degree of stability and good interior sealing, which allows high pressures.

(4) Orbitrol: Orbitrol

El orbitrol es el elemento de control central de la dirección hidrostática. El caudal transportado por una bomba hidráulica se canaliza según el movimiento del volante a los espacios de trabajo de un cilindro hidráulico, que activa la dirección de pivote. Para garantizar la función continua de las direcciones se utiliza una válvula de prioridades.
