Hey there! As a supplier of CK45 hydraulic piston rods, I often get asked about how to calculate the weight of these rods. It's an important thing to know, whether you're in the middle of a project or just planning one out. So, let's dive right into it and break down the process step by step.
First off, let's talk a bit about CK45. CK45 is a type of carbon steel that's widely used for hydraulic piston rods. It's got great mechanical properties, which makes it perfect for these high - stress applications. If you're interested in different types of CK45 hydraulic piston rods we offer, you can check out 45 Steel 30 - 55HRC QT+induction Hardening Round Bar, CK45 Hard Polished Hydraulic Piston Rod, and CK45 Hard Chromed Rod Hydraulic Cylinder Piston Rod.
To calculate the weight of a CK45 hydraulic piston rod, we're going to use a pretty straightforward formula that's based on the volume and density of the material. The formula for the volume of a cylinder (which is what a piston rod basically is) is V = πr²h, where V is the volume, r is the radius of the rod, and h is the height (or length) of the rod.
Let's say you've got a CK45 hydraulic piston rod with a diameter of 50 mm and a length of 1000 mm. First, we need to convert these measurements to meters because the density of steel is usually given in kg/m³. So, the diameter of 50 mm is 0.05 m, which means the radius r = 0.025 m, and the length h = 1 m.
Now, we can calculate the volume using the formula V = πr²h. Plugging in the values, we get V = π × (0.025)² × 1. Using a calculator, (0.025)² = 0.000625, and π is approximately 3.14. So, V = 3.14 × 0.000625 × 1 = 0.0019625 m³.
The next step is to find out the density of CK45 steel. The density of carbon steel is typically around 7850 kg/m³. This value can vary a bit depending on the exact composition and heat treatment of the steel, but 7850 kg/m³ is a good average to use.
To calculate the weight (mass) of the piston rod, we use the formula m = ρV, where m is the mass, ρ is the density, and V is the volume. We already found the volume V = 0.0019625 m³, and the density ρ = 7850 kg/m³. So, m = 7850 × 0.0019625. Doing the math, we get m = 15.405625 kg.
If you're dealing with a piston rod that has a more complex shape, like a stepped piston rod, you'll need to break it down into smaller, simpler cylinders. Calculate the volume of each cylinder separately using the V = πr²h formula and then add up all the volumes. Once you have the total volume, you can use the m = ρV formula to find the weight.
Let's take an example of a stepped piston rod. Suppose it has two sections: the first section has a diameter of 40 mm and a length of 300 mm, and the second section has a diameter of 60 mm and a length of 700 mm.
For the first section:
Convert the diameter to meters: 40 mm = 0.04 m, so the radius r₁ = 0.02 m, and the length h₁ = 0.3 m.
The volume of the first section V₁ = πr₁²h₁ = 3.14 × (0.02)² × 0.3 = 3.14 × 0.0004 × 0.3 = 0.0003768 m³.
For the second section:
Convert the diameter to meters: 60 mm = 0.06 m, so the radius r₂ = 0.03 m, and the length h₂ = 0.7 m.
The volume of the second section V₂ = πr₂²h₂ = 3.14 × (0.03)² × 0.7 = 3.14 × 0.0009 × 0.7 = 0.0019782 m³.
The total volume V = V₁+V₂ = 0.0003768 + 0.0019782 = 0.002355 m³.
Using the density of 7850 kg/m³, the weight m = ρV = 7850 × 0.002355 = 18.48675 kg.
It's also important to note that if your piston rod has any holes or grooves in it, you'll need to subtract the volume of these features from the total volume of the rod. For example, if there's a hole in the center of the rod with a diameter of 10 mm and a length equal to the length of the rod, you'd calculate the volume of the hole using the same V = πr²h formula and then subtract it from the volume of the rod without the hole.
