The calculation method of the support force of the hydraulic prop, I'll take a look at the acrow prop calculation process with you.
Q:What is the required concentration of pump station for hydraulic prop?
A:General 3% to 5%
Q:How does the initial bracing force of acrow prop come from 90 kN, 12 MPa in enterprise standard and 6 MPa in industry standard And How to calculate the initial bracing force of adjustable prop?The unit of pressure gauge is PA, the outlet pressure of pump station is 30MPa, the enterprise standard is 12MPa, and the industry standard is 6Mpa. How to convert it?
A:Megapascal: refers to megapascal, i.e. 1000000pa
The enterprise standard is generally stricter than the industry standard, so it needs a high point.
Industry standard refers to the common and lowest standard of this industry.
The initial bracing force is 90 kN, which is the initial pressure value
The pump station outlet pressure 30MPa refers to the maximum working pressure of the acrow prop pump. It has nothing to do with the press.
The initial bracing force of the single hydraulic prop with a diameter of 100 mm is calculated according to the industry standard of 6 MPa
0.1 * 0.1 * 3.14 / 4 * 6 * 1000000 = 47100n
Enterprise standard 12 MPa 0.1 * 0.1 * 3.14 / 4 * 12 * 1000000 = 94200 n
That's 90 kN
Kg / cm2 is the concept of stress, that is, the force received per unit area, while kn is only the concept of force, and the two cannot be equal.
1n/mm2=1Mpa
1N/m2=1Pa
1kg=9.8N
1m2=10000cm2
So 1kg / cm2 = 98kpa = 0.098mpa
In engineering, people approximately take 1MPa = 10kg / cm2
It's a bit complicated, but it's not much for professionals. If you need hydraulic prop or consult with us, please contact us.
