A previous blog mentioned an online calculator for determining the correct diameter of hose to use in any hydraulic application, and these tools are invaluable for checking calculations and finding answers quickly. Regular visitors to our website will be familiar with our page of hydraulic calculation tools, but those who have not spent a lot of time navigating the site may be unaware that we offer these hydraulic calculator tools . Each calculator is displayed with clear instructions on how to use it, so even for trainees and students they are sensible things to refer to. The pump flow and output power calculators help you size a power pack and pump for your desired application, while the input and output torque and motor speed calculators relate to the operation of hydraulic motors. These five calculators are invaluable for making decisions about the choice of power pack, pump and motor. They are also very handy when making changes to hydraulic equipment, as you can check whether the changes you want to make are actually feasible with the equipment you have. We also have a pipe diameter size calculator and one for both known and unknown hydraulic cylinders. The unknown hydraulic cylinder calculator is an excellent starting point for designers, as it will guide you in the right direction to choosing a cylinder size; as long as you know the purpose and therefore the thrust and pressures involved. It should be borne in mind that while these calculator tools are good for checking and guidance, they are no substitute for the knowledge and experience of a hydraulic engineer, and the outputs from these calculators should not be solely relied upon to inform your purchases of equipment, or the final design of any machinery. Take a look at our website section today, and be sure to bookmark it for future reference.
