Load Sensing Dynamic Non Reaction Hydraulic Steering Unit 50 Ml/R - 1000 Ml/R 16 Mpa

Load sensing dynamic non-reaction steering units 50 ml/r - 1000 ml/r 16 Mpa

Hydraulic steering control unit(SCU) is widely used both in the steering system of vehicles and the marine rudder. The operator can obtain bigger steering control force with less steering force,and its function is more safety and reliable, its operation is more smooth and flexible.

BZZ5 Series Hydraulic Steering Control Units (SCU)

As for load sensing steering system, the steering system and the

operational system may use the same pump through the priority

valve or the load sensing system can distribute the surplus oil of

the steering system into the operational system. Meanwhile, if the

pump with load sensing is used , the load sensing will have obviously

productive results.

Load sensing

In load sensing steering systems both the steering system and the working hydraulics can be supplied with oil from the same pump, using a load sensing pump, also delivers the potential for energy saving.

Load sensing steering units have an extra connection for load sensing (LS), so that a load pressure signal can be directed via the steering unit to a Danfoss priority valve and/or an LS pump. The load sensing signal controls the oil flow from the priority valve (and/or the LS pump) to the steering unit. The LS connection is open to tank when the steering unit is in the neutral position.

The LS port of the load sensing steering unit has to connect with priority valve or LS port of load sensing pump, so that the signal of the steering load pressure of the steering unit can be transferred to priority valve or load sensing pump through oil hose ( we suggest that the length of the hose is ≤2 m), to control the oil volume supplied to

steering unit by the control system.
