Model BZZ5 Hydraulic Steering Control Units (SCU)

Date:2016.11.12 Author:libo@aniec.com Source:Hydraulic motors Views:1382

BZZ series hydraulic steering unit is consisted of  one pair of rotary valve and one pair of  gerotor. Via the steering column, the steering unit links the steering wheel, when the steering wheel rotates, the oil flows out of the supply pump of the steering system  , through the rotary valve and the gerotor , to the cylinder’s port left or right ( depend upon the rotation direction). The gerotor supplies the oil to the steering cylinder in proportion to the angular rotation of the steering wheel. If the oil flow out of the supply pump of the steering system is too small, the steering unit can work as the manual pump.

Characteristic Features
Model BZZ5 load sensing steering with BZZ1/BZZ2/BZZ3 advantages, also has following features: 
Provide reliable, smooth pressure compensated steering, because pressure variations in the steering circuit do not affect steering response or maximum steering rate, and the steering circuit always has flow priority 
Only the flow required by the steering maneuver goes to the steering circuit. Flow not required for steering is available for use in the auxiliary circuit. Therefore power loss is decressed, system efficency is increased.
