Hydraulic steering control unit(SCU) is widely used both in the steering system of vehicles and the marine rudder. The operator can obtain a bigger steering control force with less steering force, and its function is more safe and reliable, its operation is more smooth and flexible.
BZZ1, BZZ2, BZZ3 series SCU offers the advantages as follows:
1. This kind of SCU series can help you reduce machinery cost without mechanical linkage devices, and can offer reliable and light structure.
2. This kind of SCU series can operate more flexibly with light steering torque.
3. This kind of SCU series can offer emergency manual steering in case of engine failure.
4. This kind of SCU series can be steering at continuous speed with less steering torque.
5. This kind of SCU series can offer various hydraulic systems and different mounting choices.
6. This kind of SCU series can link various steering pumps and hydraulic steering systems
In addition to the advantages mentioned above, the BZZ5 series SCU has the features as follows:
BZZ5 series SCU can supply priority relative flow to ensure reliable, sensitive and flexible steering according to the requirement of hydraulic steering system, whether the load pressure is big or small, or the steering wheel rotates quickor slow.
In addition to the necessary flow supply to the steering system, the remaining flow out of the pump can be supplied to subsidiary flow system, so that the system can avoid the power loss caused by surplus flow out of the steering flow system, and the system efficiency can be increased.
