Hydraulic Cylinder Guide: Sizing a Replacement
There are countless sizes 和 types of hydraulic cylinders, which is why it’s important to size them before purchasing a replacement. If you’re not familiar with this process, keep reading. In this article, we’ll outline the process step-by-step, including any formulas 和 conversions that you need to know.
Steps to Sizing a Cylinder
Sizing a hydraulic cylinder is a straightforward process that only requires a tape measure 和 calipers. Here’s a step-by-step guide:
步骤1
Measure your cylinder’s bore, which is the internal diameter of the cylinder’s barrel.
步骤2
Measure the diameter of the piston rod, which is the circular steel cap attached to the piston.
步骤3
Measure the cylinder’s retracted length, which is the distance between its pin holes when it is fully closed.
步骤4
Measure the cylinder’s extended length, which is the distance between its pin holes when it is fully opened.
步骤5
Calculate your cylinder’s stroke by subtracting its retracted length from its extended length.
步骤6
Carefully inspect all hose ports 和 other components of your hydraulic cylinder, looking for excessive wear or damage. It’s smart to order any needed replacement parts when ordering your cylinder. During your inspection, also be sure to take note of the thread type 和 size of your port. If any replacement hose ports are not the same thread type or size, you will need to purchase an adapter.
步骤7
There are endless options for mounting hydraulic cylinders on machinery. Each original equipment manufacturer utilizes its own designs. You may need to take separate measurements if you’re working with cross tube cylinders, clevis end cylinders, tang cylinders, swivel eye cylinders, or trunnion cylinders.
步骤8
The last step is to determine the working pounds per square inch (PSI) of your hydraulic fluid pressure system.
Hydraulic Cylinder Formulas Chart
There are various hydraulic cylinder calculation formulas that you can use to make your life easier. Just plug in the variables to determine the values you require. Here are some of the most useful definitions to keep in mind.
- :英寸
- HP: Horsepower
- MM: Millimeters
- T: Torque in foot-pounds
- GPM: Flow in gallons per minute
- F: Force or thrust in foot-pounds
- A: Area of piston in square inches
- PSI: Gauge pressure in pounds per square inch
Formula to Measure the Force of Fluid Flowing Through a Pipe:
HP = (PSI x GPM) / 1,714
Formula to Determine the Force Created By a Cylinder:
F = A x PSI
Formula to Convert Millimeters to Inches:
MM = IN x 25.4
Formula to Convert Inches to Millimeters:
IN = MM × 0.03937
The above hydraulic cylinder formulas are especially useful when you have access to a hydraulic cylinder size chart, which lists out common cylinder 和 component dimensions.
