Power Steering

Power steering assists the driver of an automobile in steering by directing a portion of the vehicle’s power to traverse the axis of one or more of the road wheels. As vehicles have become heavier and switched to front wheel drive, particularly using negative offset geometry, along with increases in tire width and diameter, the effort needed to turn the steering wheel manually has increased often to the point where major physical exertion is required.


To alleviate this, auto makers have developed power steering systems: or more correctly power-assisted steering on road going vehicles there has to be a mechanical linkage as a fail safe. There are two types of power steering systems hydraulic and electric/electronic.

A hydraulic-electric hybrid system is also possible.A hydraulic power steering (HPS) uses hydraulic pressure supplied by an engine-driven pump to assist the motion of turning the steering wheel. Electric power steering(EPS) is more efficient than the hydraulic power steering, since the electric power steering motor only needs to provide assistance when the steering wheel is turned,whereas the hydraulic pump must run constantly.

 In EPS, the assist level is easily tune able to the vehicle type, road speed, and even driver preference. An added benefit is the elimination of environmental hazard posed by leakage and disposal of hydraulic power steering fluid. Also in the event of the engine cutting out, assist will not be lost where as hydraulic will stop working, as well as making the steering doubly heavy as the driver has to turn the power-assist mechanism on top of the steering system itself.

SPEED SENSITIVE STEERING:

A Interesting and innovative outgrowth of power steering is speed sensitive steering, where the steering is heavily assisted at low speed and lightly assisted at high speed. The auto makers perceive that motorists might need to make large steering inputs while maneuvering for parking, but not while traveling at high speed. 

The first vehicle with this feature was the Citro├źnSM with its Diravi layout, although rather than altering the amount of assistance as in modern power steering systems, it altered the pressure on a centering cam which made the steering wheel try to ”spring” back to the straight-ahead position.Modern speed-sensitive power steering systems reduce the mechanical or electrical assistance as the vehicle speed increases, giving a more direct feel. This feature is gradually becoming more common

Steam Reducing Station



Many industrial plants produce high-pressure steam for process work . A pressure reducing station is more than just a reducing valve fed off a steam main.  A properly designed and installed pressure reducing station takes into consideration velocity, good piping practices, and safety....

Tire Wear and Wheel Alignment

Wheel Alignment :

A wheel alignment consists of adjusting the angles of the wheels so that they are perpendicular to the ground and parallel to each other. The purpose of these adjustments is maximum tire life and a vehicle that tracks straight and true when driving along a straight and level road.





Wheel alignment is very important to ensuring your tires do not wear prematurely. A proper alignment also means less wear and tear on steering/suspension components. When a vehicles alignment is out of manufacturer recommended specification, it can cause the vehicle to drift/float or pull in different directions. 

This can prove to be unsafe for you and the vehicle. Improper wheel alignment creates excessive friction on the road surface leading to uneven tire wear and unnecessary stress on steering/suspension components. This excessive drag will also reduce fuel economy.
