1, the use of pneumatic system pressure is generally in the range of 0.2-1.0mpa, so the cylinder can not do high-power power components;
Hydraulic cylinders can do relatively large power components, the use of hydraulic systems; Nissin machinery production and sales of commonly used hydraulic
Cylinders are 7mpa, 14mpa and 21mpa respectively.
2, the cylinder used by the medium is the air, hydraulic cylinder using the medium is hydraulic oil; air can be used inexhaustible
, There is no cost and supply difficulties, will be used directly into the atmosphere of gas, easy handling, will not pollute,
The hydraulic oil is the opposite.
3, the air viscosity is small, the resistance is less than the hydraulic oil.
4, the air compression rate is much larger than the hydraulic oil, so its work is stable and the response is far worse.
