How to choose the right cylinder models!
Cylinder model selection, the main hydraulic cylinder inside and pressure.
1) stroke 300MM, thrust 4000KG, the choice of which type of cylinder?
Press 4 tons of thrust, can be calculated, if the cylinder pressure is designed to 8MPA, the inner diameter of the cylinder 80, the cylinder model 80 * 40 * 300-8MPA, can tie rod cylinders, low cost, easy maintenance.
If the cylinder pressure selection 16MPA, the inner diameter of the cylinder 60 can be, the cylinder model 60 * 35 * 300-16MPA, can be welded or tie rod.
The proposed combination of system pressure mechanical equipment, make sure the cylinder pressure. Machinery and equipment for finishing, then select the system pressure is lower, usually in 5MPA less, if rough, then the system pressure is selected larger.
Determining the system pressure equipment, projected to go inside diameter of the cylinder, and then decide cylinder connection, installation, rod end thread, install the specific dimensions and the like. Of course, installation of the cylinder and also the process of estimating the relationship, such as the cylinder is mounted vertically, horizontally mounted, or angled.
2) with two hydraulic cylinders for the top 4t lifting weights movement in the vertical direction, a stroke of 2000mm, ask how to choose the cylinder?
Important parameters of the hydraulic cylinder: Bore, stroke, pressure (or force).
Bore and pressure are two variables, such as bore 50, the use of pressure 12MPA, can reach two tons force; for example, bore 63, the use of pressure 7MPA, can reach two tons force.
The pressure in turn depends on your hardware system pressure, system pressure to see your precision machining equipment, precision machining equipment low pressure system can be set larger.
So to choose a hydraulic cylinder, the first device to determine the system pressure.
Requirements in exceptional cases the weight does not fall within the fuel tank leakage ---- higher requirements, and the hydraulic system, but also to ensure that configuration.
