Presentation

A complete range of hydraulic motors (Oil hydraulic) :

The JTEKT HPI range of hydraulic gear motors has a capacity of 0.5 to 110 cm3/rev. with a peak pressure up to 330 bar, excellent start-up pressure and flow conditions, and is the widest on the market.They are modular in design, and suitable to all market standards: ISO, DIN, SAE, Italian type, etc.

HPI motors incorporate hydraulic functions such as :

Pressure relief valve
Pressure relief valve controlled by electro-poppet-valve or proportional valve
Anti-cavitation poppet valve

This technology allows complete systems to be supplied, such as the Hydraulic Motor Control, which reduces integration time and costs.

Thus, JTEKT HPI proposes a set of solutions adapted for the speed regulation for hydraulic motors driving ventilator screws:

=> The HMC system (Hydraulic Motor Control), an exclusive HPI feature. :

Anti-cavitation function
clutch release of the drive by electrovalve
Speed Regulation function by hydraulic temperature sensor
Electronic regulation function by proportional valve controlled by electronics integrating data from several temperature sensors
