A typical hydraulic system fundamentally features an incredible ability to apply a considerably monstrous force or torque boost in a comparatively easy way. The main advantage of the process is that the action is affected without the use of any mechanically joined parts like gears, levers or similar attachments, from the point of origin of force generation to the point of impact. These systems are based on the law of Pascal where it is said that when a pressure is applied to a fluid inside a closed container, the resultant will be that the fluid will exert an equally strong pressure in all directions.
In case of these systems, the usage of a non-compressible fluid is preferred. The most spoken convenience about these systems is that a very large amount of torque and power can be transferred through tubes of considerably small cross sections, where the high power density actuators make use of this and in turn a huge multiplication of forces are obtained as an end result. A linear hydraulic motor or a hydraulic cylinder is in other words an actuator that produces unidirectional force of great volume, through a unidirectional stroke. These hydraulic cylinders get the desired power from the highly pressurised hydraulic fluids, which are commonly oils.
The cylinder is a barrel made of highly resistant material, inside which a piston is enabled to freely move back and forth. The cylinder at one is securely sealed and the other end is where the piston head gets aligned. The piston is packed with sliding rings and seals so that the fluid inside does not spurt out during the pressurising action. In this way the cylinder is mainly divided into 2 parts by the piston that is the piston head part and the bottom chamber or the cap end. The piston head part along with the piston rod is connected to the object or the machine part that pulls or pushes the piston.
Hydraulic machines find application in heavy construction sectors. Here the machines that are used must be of very high torque and power and hence the utility of hydraulic machines are more preferred. The mechanics and the system of functioning happens to be a straightforward process where the fluid is pumped into various hydraulic motors and cylinders throughout the machine, where it gets subjected to different pressures depending on the resistance, the fluid then is regulated by control valves and is distributed through strong and resistant hoses, pipes and tubes. The controlling of the fluid may either be manual or automatic depending on the application and where it is being used. For instance in case of an excavator the cylinders work in accordance to the machines linkages to carry out the desired work.
The same principle of the hydraulic system is made use of in case of fork lifts, elevators, hydraulic cranes, earth moving equipment, and many more sectors where enormous power and torque are mandatory to carry out the job. Most of the hydraulic equipment, since they do not involve many mechanically moving parts that are literally connected to each other, seldom require frequent servicing but all the same due to the fact that they are used in very heavy works especially in earth moving and heavy load lifting, it needs to be supervised and kept well-tuned up always. Although not comprising of complex structures, it has to be serviced and maintained by a skilled and qualified technician so that the machine does not come across any technical faults leading to hampered jobs or work location causalities.
While discussion on this aspect wwg engineering, well-known organization dealing with industrial machinery and services, specialising in hydraulic equipment and allied facilities have been a forerunner in the mentioned sector. Rendering second to none services in and around Singapore since the last two decades, have much more than hydraulic equipment services, hydraulic cylinder repair and maintenance services, the organization is also proficient in thermal spray coating, rotating equipment servicing and repairs, process piping and plumbing services, chrome plating, gear fabrication, balancing machine servicing and more. With a steadfast mission to offer excellent services in the mentioned sector, wwg engineering has been one of the preferred organizations when it comes to hydraulic machinery, its servicing, repairs, and maintenance.
