How can we judge the shortage of the tonnage of a cutting machine? [Ponse cutting machine]
The pressure calculation method of the cutting machine is: the system pressure to multiply the piston area of the cylinder; the formula everyone will calculate, the key is that the specific value is not known so that it can not be calculated. But if you are careful to find that the hydraulic oil pump nameplate has the rated pressure standard, remember the numerical value, then the cylinder diameter; the system pressure multiplied by the cylinder piston area and the oil cylinder number, so that we can roughly calculate the machine pressure.
The above is the calculation method. Now let's see the specific pressure of the cutting machine.
1, directly in the hydraulic system and the pressure gauge, pressure to get the numerical value; if this value is close to the rated value of the hydraulic oil pump, then the machine pressure is normal. If the numerical difference is too large, it indicates that there is leakage in the hydraulic circuit or the pressure of the hydraulic pump attenuates. The current value and the rated percentage of the hydraulic pump can calculate the actual pressure of the cutting machine.
2, directly take the pressure detector on the workbench to press the reading, this is very simple, the instrument has converted the measured value to tons, but the instrument is more expensive, the general manufacturer will not buy one back to use.
3, experience, listening to sound, watching movement and static to estimate, this must have some basic skills or long exposure to the machine to see.
