Some considerations when choosing a Romhit hydraulic cylinder are:

Quality of hydraulic cylinder

The first step is to determine how much mass you need to move. Once you know how heavy the mass is, you consider the effect of the mass on the force required to move it. For example, if a load is pushed vertically upward, it only needs a force equal to its weight to lift it, but if it is pushing a load on the ground, you will have to overcome friction and acceleration. Also note that, to be safe, it is best to assume a force 120% greater than the calculated result.

Cylinder diameter

The next step is to calculate the diameter of the cylinder. The force generated by the cylinder is the product of the system pressure times the area of the inner surface of the piston on which the pressure acts. This is the formula used to calculate the aperture required to achieve this force.

The maximum pressure range of the application will also change the aperture. Depending on the specific job the system is performing, the stress can vary greatly. The cylinder is suitable for test pressure and nominal standard pressure, thus adapting to changes. The system pressure must not exceed the nominal rated design pressure of the cylinder.

Rod size

The next step in selecting any hydraulic cylinder should be to select the appropriate rod size. Most standard cylinders come with one or two rod options. Choosing the desired rod size requires careful consideration of the required stroke length, which in turn affects the buckling strength of the rod. In addition to rod buckling, bearing load is another consideration in the selection of hydraulic cylinders. Increasing the stroke length of the cylinder also increases the synthetic bearing load on the piston rod.

When it is decided that push or pull or both are double acting, if the hydraulic system is performing double acting, the answer may require a specific double acting cylinder. Since the single acting cylinder extends the piston under hydraulic pressure, the double acting cylinder will extend and retract the piston under pressure. For push applications, it is important to correctly size the rod diameter to avoid rod buckling. For traction applications, it is important to correctly determine the ring area or piston diameter area minus rod diameter area in order to move the load at the rated design pressure of the cylinder.

If choosing from the standard cylinder rod options, it is recommended that for a given hole, the smaller rod is used only for small stroke push load or decompression applications, and the larger rod is used when maximum reliability and fatigue life is desired. If it is determined that the required piston rod diameter exceeds the maximum available piston rod diameter within the selected cylinder hole dimensions, it may be necessary to reconsider the design parameters.

When determining the desired stroke length, if the space does not fit the ideal length, a telescopic configuration, or even a radial configuration that allows the cylinder to move on multiple axes, may be required. Long stroke cylinders are often at risk of distortion or misalignment and require additional support.

Cylinder gasket

If the cylinder diameter, piston rod and stroke dimensions have been determined, another aspect to consider is whether internal cushioning is required at the end of the cylinder stroke. It is recommended to use cushion when decelerating the high-speed piston rod to reduce the impact energy of the piston assembly on the cylinder end cap. The use of cushioning does not affect the cylinder housing or mounting dimensions.

When deciding how much support the piston and cylinder need, it all depends on the length of the stroke, the stop tube necessary to stop excessive wear and jack cutting. However, the stop tube does not prevent the rod from bending; According to Euler's calculations, you might need a super pole. The most common mistake in hydraulic design is underestimating the specifications of the piston rod, making the cylinder more susceptible to stress, wear, and failure.
