Versatile Hydraulic Engineering

The fact that hydraulic technology has revolutionised engineering applications needs no second opinion. This science has lent an unmatched impetus to dynamics and also made easier the functioning of almost every other utility or activity.  For instance, hydraulic power systems are used extensively in aviation, both in the aircraft and allied systems on the ground. The technology has kept pace with the developments witnessed vis-à-vis newer models of aircraft and other gadgets.

A hydraulic power pack is a simple consisting of an electric pump, filters, reservoir, valves, and pressure relief valve. It has several benefits such as doing away with a centralised hydraulic power supply system and long stretches of hydraulic links. Thus there is considerable reduction in weight. A power pack may be driven either by an engine gearbox or an electric motor. The weight is reduced by the integration of essential valves, filters, sensors, and transducers. Thus chances for external leakage are eliminated and thereby simplify troubleshooting as and when the need arises. Some power pack systems are designed and made with an integrated actuator. These systems have applications in controlling the stabilizer trim, flaps, landing gear, brakes and also flight controls with perfection.

Special Hydraulic Cylinders

In a hydraulic system, the cylinder is one of the most important integrated parts. It is a mechanical actuator that is renders a unidirectional force through a unidirectional stroke. There are variants like special hydraulic cylinders. Depending on the design and applications, these are mainly:

  • Telescopic
  • Plunger
  • Differential
  • Position sensing also known as ‘smart’

Hydraulic cylinders have thousands of applications, particularly in earth moving and specialised vehicles like excavators, dumpers and bulldozers used at construction sites and mines, manufacturing machinery, garages, winches in ports and civil engineering. The hammer used in piles foundation is a ready example.

Ways For Hydraulic Inventory Maintenance

The technology alone can not sustain production, it is important to pay equal stress on its maintenance as that on innovation. Various Hydraulic components like Mobile Hydraulic Cylinders, Pumps, Motors, etc. are not easy on pockets for frequent replacements. Thus it is important to know what all it takes to maintain inventory health of these hydraulic components for effective functioning. It is necessary to ensure that your hydraulic inventory isn’t degenerating while sitting in warehouse. Read on to find a few pointers that help in proper long-term storage of the inventory.

Use clean oil always for filling the components

Whether it’s under operation or shed, hydraulic equipment must have pure oil. The use of the finest oil becomes more important if you have a large-diameter, high-pressure hydraulic motor, cylinder or pump. Of course, nobody would like an expensive component to be out of kilter much before the first year of servicing. Therefore, it’s necessary to fill components using clean hydraulic fluid. However, filling components with oil isn’t a cakewalk. You’ve to do a lot of groundwork and exercise great cautions.



Protecting exposed metal parts

It’s apt to smear the innards of a hydraulic cylinder (preferably eyes, bearings and clevis bushes) with grease. The drive shafts of motors as well as pumps must be wrapped using an oil-impregnated tape. Before using such tapes or similar products, you should ensure that the drive shafts are completely retracted. If, however, oil-impregnated tape is applied upon drive shafts or cylinder rods when they’re not retracted, then irrevocable damage can happen. 

Storage in dry and neat surroundings 

Storing bulky inventory such as large-sized, hydraulic cylinders indoors is terrorizing for even the most experienced warehousing managers. Indoor storage of the inventory is easy for compact-sized components such as pumps, motors, etc. Adequate space management has to be done in warehouses for storing bulky components indoors. It’s not at all advisable to store any such equipment out in the open.

Thus, it’s necessary to properly store such type of inventory for maintaining Hydraulic Cylinder Design and life. Machines and equipment working on the technology must be stored in dry, clean, cool places.

A Guide To Select The Best Hydraulic Fluid

The contemporary culture requires hydraulic systems to operate within a demanding environment. A demanding environment for hydraulic fluids, in general, requires them to work at high speed, soaring temperature as well as pressure . The ideal temperature, pressure and speed help systems work without any hassles in a more efficient manner. Such an idealistic environment is sustained within hydraulic machinery if the best fluid is put to use. Each of the hydraulic system components needs the best fluid so as to work without any glitches.

The characteristics of the best hydraulic fluid

Some noteworthy characteristics of the finest hydraulic fluid are as follows:-
  • The oil Increases the operational efficiency of the equipment
  • The oil enhances the operational performance
  • The oil is also responsible for minimizing the wear and tear of an equipment
  • The oil helps the machinery resist very harsh working environments
To perform different roles, the oil should have the best chemical and physical properties. Such type of properties helps in dealing with the environment’s hostility as well as the  duty cycle’s rigorousness. Mentioned below are a few steps that should be kept in mind before buying hydraulic fluid.

Some steps to be harbored

Analyzing the system's pump is significant

Never ever expect a hydraulic machinery to have a similar pump design. The cutting-edge technologies and rate of innovations have helped build the best pump designs. In general, a pump design consists of vane, piston, and gear (internal and external). Every pump design helps hydraulic equipment perform a specific job.

Choose fluids as per the task performed by the machinery 


 





Smooth operation of hydraulic machines is maintained by using the best-in-class hydraulic lubricant. The fluid should be able to allow heat transfer to happen without any hassles. The same fluid, however, is not a great choice if the machine has a risk while working in high temperatures.

The significances of such a fluid are understood by car parking system manufacturers who develop machines that have to completely rely upon it.

Get The Best Hydraulic Solutions

Knowing about hydraulic solutions is not very common. Sounds like a technical term, hydraulic systems and machineries play a very crucial role in the construction industry. So, let’s begin with knowing the term hydraulics first.

Hydraulics – is a scientific term in engineering which deals with the mechanical properties of liquid. Hydraulic machines are used to generate, control and transmission of power by pressurized liquid. These machines use liquid fluid power to perform any task. In these machines, hydraulic fluid transmits throughout the machine through hydraulic cylinders and motors. The fluid is controlled by valves directly or automatically.

Hydraulic machines are hugely popular because massive power can be transferred through small tubes and hoses. The best example to understand the hydraulics is the brakes in your car. Yes, brakes in cars use the hydraulics! Dump trucks are another example of hydraulic system.

Construction sites are the common places where hydraulic machines are seen.  Heavy duty hydraulic cylinder is also used at major construction sites.

There are many companies providing the hydraulic solutions. Creating hydraulic components and systems demand attention to each detail. Quality of components is a must to perform on sites.

To get the best hydraulic solutions, either you can contact the companies providing these solutions directly or if you do not have any idea about the industry, start with the search on the internet. As almost all the companies have their websites, you can easily look out for a particular company’s products and services. If product and services satisfy you, directly contact the company or you can talk to some of their clients to know their quality of services better.

You can contact them through mail or call. Mail is the better way to cite your requirements but calling is always a good idea to make a better communication in order to get the specific solutions.

Everything About Hydraulic System’s Preventive Maintenance

Many companies spend resources to train their maintenance teams for aptly troubleshooting hydraulic equipment.  If we focus on averting hydraulic system failures, then a less amount of money and time is required to troubleshoot. In general, many accept hydraulic failures as the inevitable. We should invest resources to root out system failures. Shifting the focus to proactive from reactive maintenance is required. A proactive maintenance approach is needed to avoid unscheduled system failures.

Fewer periodical maintenance schedules are the key reason for hydraulic equipment’s failure. For example, if a hydraulic power pack is not maintained regularly, then you can expect the entire system to crumble. It is necessary for well-defined maintenance techniques to be implemented. The best maintenance technique for any hydraulic system or component is Preventive Maintenance (PM). More and more preventive maintenance programs help make equipment reliable.


Preventive maintenance

Preventive Maintenance is, by far, the most simple sustenance program for any type of hydraulic machinery. PM must be done religiously to make it a result-oriented activity. Most organisations have excellent PM procedures in place. Such procedures help in proper execution of each and every step performed by a hydraulic machine. For developing a high-quality PM program, a company should follow the below mentioned steps. 

Identify the system’s operating conditions.

  • Does the machinery operate 24×7?
  • Does the system operate at the highest pressure as well s flow?
  • Is the machine located in a humid, dirty environment?

Quiz your equipment manufacturer about the machine’s PM requirements.

What operating parameters are defined by the equipment manufacturer? The operating parameters must be in confirmation to the hydraulic liquid ISO particulate.

What operating parameter does hydraulic cartridge valves manufacturer define for the equipment’s PM program?

What parameters are defined by the equipment’s filter manufacturer to set up a PM program?

Last, try to gather the equipment’s history for setting up a reliable PM program.

For having the best preventive maintenance procedure, you must have a thorough understanding of your equipment.

Seven Mistakes Done While Working With Hydraulic Equipment

Maintenance is a critical element to ensure any machine’s longevity. Even the most seasoned hydraulic machinery operators can botch it up, if they tend to overlook some critical factors. While working with hydraulic equipment, the user has to keep in mind some points.   Read on to discover the mistakes that can be sometimes committed by even an experienced user.

Forgetting to change the filters

Most experts change the oil filters according to a schedule. However, it is advisable to check the filters manually before changing. When the hydraulic filters are changed according to a strict schedule, then chances are abundant that the operator might end up either under utilising or overusing them. It is better to check the filter every now and then to know the level of dirt clogging it.

Whenever, the operator notices the density of dirt is heavy then it becomes advisable to change the filters. If done otherwise, the dirt will pass through the filter and jeopardize the performance of the equipment.

Forgetting to change the oil

Changing the hydraulic oil depends upon two factors:-

  1.    Reduction in the additive package
  2.    Debasement of the base oil

Both these factors depend upon the hours of work done by the machinery. However, replacing the oil squarely on the basis of hours of service rendered by the equipment is incorrect. Proper oil analysis must be done before throwing the oil tin in the trash barrel.

Running hot

High temperature kills even the most advanced hydraulic machines. The most affected components of a hydraulic machine – when overused – include double acting hydraulic cylinder, Hydraulic AC&DC Power Pack, Piston, hoses, pumps, seals and oil itself.

Proper know how of the technology is evident for users before beginning to work with a hydraulic system. Also, the knowledge of operating as well as maintenance is necessary for every hydraulic machine operator.

Guide To Select The Best Hydraulic Fluid

The present-day working environment overtly demands hydraulic systems to operate at high temperature, pressure and speed.  Such an ideal pressure, speed and temperature aid equipment to work to the best of its abilities. All such idealities are created within a system if it is lubricated using the best hydraulic fluid. With so many significant products (HydraulicRams, Hydraulics Cylinder, Manifold Block, etc.) running on the technology, the need to select the best fluid has become urgent.

A first-rate hydraulic fluid:-

  •   Enhances operational efficiency of an equipment
  •   Fosters operational performance
  •   Minimizes the equipment’s wear
  •  Lets the machinery withstand the harshest of working atmospheres

For performing such diverse roles, the fluid must have excellent physical and chemical properties to deal with the duty cycle’s rigorousness as well as environment’s hostility. Owing to its high importance, there are certain steps that help buyers select the best hydraulic fluid.

Determine the system’s pump and its required viscosity grade

Do not expect each of the hydraulic machines to have a common pump design. The age of innovation in technology has paved way for building fresh pump designs – piston, vane and gear (external and internal). Each pump design helps a hydraulic machine perform a specific task. Based on the design of the pump, it is determined as to which fluid (of a specific viscosity grade) has to be used.

Choose fluids as per the function which hydraulic equipment performs

Smooth operations of any equipment are promised by the quality of the hydraulic lubricant it uses. The chemical composition of the fluid is modified as per the function of machinery. The type of fluid facilitating heat transfer might not be apt to ensure optimal power transfer. For example, a synthetic-based fluid can handle drastic pressure swings and temperature fluctuations. However, the same fluid is not a great choice if the equipment’s application has a risk of fire; for such an application a water-based fluid is apt hydraulics cylinder.       



Practicing excellent lubricant selection is meant to give the machine longevity.
