The calculation method of the pressure of the cutting machine is: the system pressure is multiplied by the cylinder area of the cylinder; this formula will be calculated by everyone, the key is that the specific value cannot be calculated. But if you can carefully find that the hydraulic oil pump nameplate has the rated pressure standard, remember the value, then measure the diameter of the cylinder; 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 we can see how 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 pressure of the hydraulic pump 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.
