Fluid pressure and flow are converted into force and linear motion by hydraulic cylinders and are used in a wide range of applications and industries. They are complex devices that combine a wide range of available components in a variety of dimensions and configurations built using a host of different materials.
Through over-engineering cylinder requirements, a precautionary habit in the face of ever-improving cylinder technologies, many OEM design engineers play it safe. Other engineers simply copy previous designs of equipment without taking into account variables that have gone into the initial design and developments made since then. It can save time to recycle old designs for a similar purpose, but it ignores technical developments that enhance the efficiency of hydraulic cylinders or make them move and carry more weight.
In order to achieve the highest possible safety, efficiency, and performance objectives, engineers need to remain up-to-date on technology and approach each new design. To that end, this paper will discuss when to define hydraulic cylinders over pneumatic ones, the key design variables to take into account when selecting and sizing hydraulic cylinders, common mistakes to avoid, and sometimes overlooked critical design considerations.
1. Erroneous size
The force a hydraulic cylinder can exert, as we saw in the previous section, depends on its surface area and internal pressure. Therefore, you have to work backward from your specifications to decide the correct size in terms of:
1. Velocity
2. Strength/force
3. Performance
Misjudging these requirements and thus choosing the wrong size is a common mistake. A cylinder that works at the wrong speed or lacks the ability to perform its role is the result.
2) Wrong mountings
It is important that a hydraulic cylinder with the correct components is properly installed and buy it from the best hydraulic Cylinders Manufacturers. Failure to do this can result in incorrect functions and warranty issues. It will help to prevent this issue from approaching your computer as an integrated hydraulic device. Issues most commonly occur when parts are ordered the part by part based on a part by part basis.
A hydraulic cylinder must have the necessary equipment to operate correctly:
clevis ends set or swivel
Micro or swivel feet
Mountings Flanged, Foot or Trunnion
Displacement
Consequences:
The effects of making these errors range from product failure at one end of the continuum to poor production at the other end and high operating costs. When parts need to be replaced, warranty problems are often bound to occur.
A solution to these errors:
The solution to this is to partner with a supplier who speaks your language and works with you to fulfill your specifications for hydraulics, including ordering the correct components. The business partnership begins not with the order of parts, but with a solution-focused dialogue that results in a personalized transaction to meet the unique needs of the consumer.
