The calculation method of the pressure of the cutting machine is: the system pressure is multiplied by the piston area of the cylinder; this formula will be calculated by everyone. The key is that the specific value cannot be calculated. However, if you can carefully find that the hydraulic pump nameplate has a rated pressure standard, remember the value and measure the cylinder diameter; the system pressure is multiplied by the cylinder piston area and multiplied by the number of cylinders, so that we can roughly calculate the machine pressure. It is.
The above is the calculation method, now how do we see the specific pressure of the cutting machine:
1. Connect the pressure gauge directly in the hydraulic system and pressurize to obtain the value; if this value is close to the rated value of the hydraulic oil pump, the machine pressure is normal. If the values differ too much, there is a leak in the hydraulic circuit or the hydraulic pump pressure is attenuated. The current value and the hydraulic pump's rated percentage are used to calculate the actual pressure of the cutting machine.
2, directly take the pressure tester on the workbench to get the reading, this is very simple, the instrument has converted the measured value into tons, but the instrument is more expensive, the general manufacturers will not buy one to buy back.
3, based on experience, listening to the sound, watching the movement to estimate, this must have a certain basic skills or long-term contact with the machine can be seen.
