generally speaking, the pressure of the bending machine system is designed according to 24.5mpa, and the pressure it can generate depends on the oil pump and oil cylinder ~ ~ maximum pressure, ha ha. There is no biggest, only bigger.
normal pressure 8 kg, 10 kg, 13 kg, and one can reach 14 kg. This is one-stage compression.
maximum allowable pressure: the pressure not allowed to exceed when the machine is running. In general, it is equal to the maximum pressure of the system
maximum operating pressure: the pressure acting on the workpiece. Because there is some loss of force in the process of transmission, the maximum operating pressure will be less than the maximum allowable pressure.
The maximum working pressure of air pump is 160MPa
working characteristics of air pump:
1. Output pressure range: covering the pressure range of 0.6mpa-160mpa
Compressed air, nitrogen, steam and natural gas can be used as the driving gas source of the pump3. Wide range of application: in the instrial field, it is used for clamping the chuck of machine tool, charging the accumulator, charging the high-pressure bottle, converting the low-pressure gas into high-pressure gas, etc. Whenever the air source pressure is not high enough, whether it is mechanical or electronic test device, can use Delco booster pump
Easy to adjust: within the pressure range of the pump, adjust the regulating valve to adjust the inlet pressure, and the output hydraulic pressure can be adjusted infinitely6. Automatic pressure maintaining: no matter what causes the pressure drop of pressure maintaining circuit, it will start automatically to supplement the leakage pressure and keep the circuit pressure constant
extended data:
air pumps are mainly divided into electric air pump, manual air pump and foot air pump. Electric air pump. An air pump powered by electricity compresses air continuously through electricity to proce air pressure. It is mainly used for aeration, sewage treatment, electroplating aeration, biogas tank aeration, tunnel ventilation, etc
the working principle of the air pump is that the engine drives the crankshaft of the air pump through two triangular belts, so as to drive the piston to pump air, and the gas is led into the air reservoir through the air ct. On the other hand, the gas in the air reservoir is led into the pressure regulating valve fixed on the air pump through a gas pipe, so as to control the air pressure in the air reservoir
when the air pressure in the air reservoir does not reach the pressure set by the pressure regulating valve, the gas entering the pressure regulating valve from the air reservoir cannot open the pressure regulating valve; When the air pressure in the air reservoir reaches the pressure set by the pressure regulating valve, the gas entering the pressure regulating valve from the air reservoir opens the pressure regulating valve, enters the air passage in the air pump which is connected with the pressure regulating valve, and controls the air inlet of the air pump to be normally open through the air passage, so as to make the air pump operate with no load

PS = P + W-F
where PS is the maximum working pressure, kn; W -- weight of movable beam and upper die fixed on it, kn; F -- the friction force proced by each
relative motion of the press ring pressing, kn< The ratio of the maximum working pressure to the nominal pressure is called the hydraulic press efficiency, which is generally 0.85-0.90o
