When the hydraulic steering gear is started with full load, it should be noted that the starting torque of the steering gear is short. Because its starting torque is shorter than the rated torque, if ignored, it will make the working mechanism unable to operate. When the inertia of the driven part is large, if it is required to achieve braking or steering in a short time, a safety valve should be set in the oil return circuit to prevent a sharp hydraulic shock and damage accidents.
When the hydraulic steering device is used as the power part of the lifting or walking device, the speed limiting valve must be set to prevent the rapid fall of heavy objects or the occurrence of speeding when the walking mechanism such as the vehicle goes downhill, resulting in serious accidents. Also, because the back pressure of the hydraulic motor is higher than the atmospheric pressure, the drain pipe of the motor should be led back to the tank separately, and can not be connected with the return pipe of the hydraulic motor.
In addition, because the hydraulic steering gear always leaks, so close its inlet and outlet to brake, it will still have slow slip. When it is necessary to brake for a long time, a brake to prevent rotation should be set up separately. For more information about hydraulic steering gear, you can pay attention to our website.
