Product Description

 

BZZ Hydraulic Steering Unit For Wheel Loader Eaton Type Wa100

BZZ1,BZZ2,BZZ3 series SCU offers the advantages as follows:
This kind of SCU series can help you reduce the machinery cost without mechanical linkage device, and can offer reliable and light structure.
This kind of SCU series can operate more flexible with light steering torque.This kind of SCU series can offer emergent manual steering in case of engine failure.This kind of SCU series can be steering at the continuous speed with less steering torque.This kind of SCU series can offer various hydraulic system and different mounting choice.This kind of SCU series can link various steering pump and hydraulic steering system.
 

 

Product Feature:
 

• 1.Low cost, reliable. 

• 2.No load reaction on the steering wheel comfortable. 

• 3.Manual operation available when the pump doesnt work. 

• 4.Low control torque, continuous operation. 

• 5.According to the system, different function and pressure level valves available.

Note 1: represents Function Code, BZZ2 can be chosen for SCU with the displacement of 50-200mL/r. BZZ1 or BZZ3 can be chosen for SCU with the displacement of 50-1000mL/r. 
Note 2: "Flow" that we suggest to use is the flow of 1.25 times as much as that at the steering wheel's rotation speed of 60 r/min. If the design of the system can't meet the requirements, the flow is allowed to be adjusted a little bit.

Common causes of failure and troubleshooting:

 

ProbleM	Causes	Troubleshooting
Oil leakage on the joint surface between the steering unit rear cover, stator and valve body	rear cover stator bolt looseness (or uneven force), or O-rings damaged	Evenly tighten the bolt, replace the seal
Oil leakage at steering shaft	Excessive wear or damage of the seal ring at the shaft of steering unit	Replace new seal
feels light when turn the steering wheel slowly, feels heavy when turn the steering wheel quickly	Insufficient oil supply from the oil pump to the steering unit	Check whether the oil pump is working properly (including liquid level, oil pump efficiency, pipeline smoothness, etc.)
There is foam in the oil, irregular sound, the steering wheel turns and the cylinder does not move	There is air in the steering system	Eliminating the air in the system, Check the suction pipe leaks or not, Or if the return nozzle is below the liquid level
Heavy steering continues to occur	The oil in the tank is below the specified position	Add oil to prescribed height
	Oil viscosity is too high	Use oil as required
Fast and slow steering wheels are both heavy, and there is no pressure on steering	Check valve of the P and T fails	Check the ball. If the steel ball is missing, then insert the steel ball; If the ball gets stuck dirty, it should be cleaned; In both cases, it is necessary to check the effectiveness of the sealing tape recovery.
No load or light load turns light, increase load turns to heavy	Relief valve is of system's pressure lower than required value	Adjust the pressure of the relief valve to the specified value (but not more than 16 MPa)
	Relief valve stucked by dirt, Or spring failure,Or seal is damaged	Clean the relief valve (check the effectiveness of the sealing tape), or replace the spring or sealing ring
Steering wheel cannot be automatically centered	Spring broken or deformation	Replace with new spring
Steering wheel rotates or swings left and right automatically	Rotor and the linkage shaft are in the wrong position	Stop immediately! Align the rotor and linkage shaft
Can not reach an end position	Low pressure on relief valve	Properly increase the pressure of the safety valve (it is best to adjust with a pressure gauge)
After turning to the end, the steering wheel can still be easily turned	Low pressure on shock valves	Properly increase shock valves pressure (it is best to adjust with a pressure gauge)
when machine is off, turn the wheel, cylinder not move	radial clearance or axial clearance is too large between radial and stator	Replace rotor and stator
	Low viscosity of oil	Change oil
Slow cylinder action	shock valves failure (ball caught by dirty, or spring failure, or seal damage)	Clean shock valves, replace spring or seal
Pressure of Steering system not able to be adjusted	Spring broken	Replace the spring
	Safety valve sealing quality is not high	Replacement parts
	Spool blocked	Take out, check, and refurbish
	Poor spool action	Check whether the spool is blocked
	Spring bent or too soft	Replace the spring
	Oil is not clean and the spool hole is blocked	Replace clean oil and clear spool holes
