How to maintain power steering?

The power steering is especially important in facilitating and directing the steering wheel , especially when the car is stopped

And its presence makes you direct the steering wheel and the front wheels, whether left or right, smoothly and easily

And in order to maintain the level of performance of this feature, it must be taken into account that It does not wear out quickly through two methods :

 The first : how you are dealing with it, such as pressing left and right on the steering wheel to reach the maximum rotation and maintain the degree of tire pressure regularly and equal for the front wheels.

Second : Continuous follow-up and maintenance procedures, such as ensuring that there are no liquid leaks on any part of the Power Steering unit :

– The stability of the liquid level inside the power oil container, taking into account the difference in its size if it is cold, dirty, and its effect on the liquid gauge.

– A periodic observation to ensure that there is no leakage in the cycle shown in the image of the subject above.

 – Smooth handling of the driving wheel so that the auxiliary pressure does not rise due to its effect on damaging pressure hoses or oil barriers, known as Oil Seal.

– Check for any loudness in the sound of the power liquid pump when turning the wheel.

Main components of power steering system.

1. The Pump

The power steering pump’s job is to pressurize the hydraulic fluid. Inside of the power steering pump lies a rotor equipped with vanes around perimeter. As the rotor spins, it pulls power steering fluid out of the reservoir, increasing its pressure. This pressurized Liquid then travels on to the steering rack, where it enables the appropriate movement.

Power steering pumps also contain a special pressure-relief valve to ensure that system pressure never becomes too high. Excessive pressure could easily damage the rotor or other internal components.

2. The Pump Pulley

Like a multitude of other components beneath your hood, the power steering pump receives its own power from your car’s engine. The key intermediary between engine and pump goes by the name of the pump pulley. The pump pulley attaches to the engine’s crankshaft by means of a special belt; as the crankshaft rotates, so does the pulley.

A second belt then passes this rotational force on to the pump itself. Without a working pulley, your power steering system cannot do its job. Over time, the belts used by the pulley system often become worn and stretched. Such belts can no longer effectively transmit force. As a result, you may find that your power steering becomes choppy or fails to respond altogether.

3. The Rotary Valve

Your power steering system doesn’t need to engage at all times. When you travel down the road in a straight line, without exerting any force on the steering wheel, the power steering system remains idle. Yet the moment you turn your steering wheel, the system must instantly respond.

The component known as the rotary valve has the important job of sensing any force applied to your steering wheel. Furthermore, the valve also directs the flow of hydraulic fluid to the appropriate side of the power steering system, depending on the direction of your turn.
