Are hydraulic and pneumatic transmission machinery and components, such as oil cylinders, cylinders, etc.
Not a pressure vessel Only the containers that meet the following three conditions are called the pressure vessels: (1) working pressure (note 1) greater than or equal to 0.1 Mpa (work pressure refers to the pressure vessels under normal working condition, the top can reach the highest pressure (pressure)); (no liquid static pressure) (2) the diameter of the inner diameter (for the non-circular section, the width of the width of the diagonal, or the diagonal of the diagonal) is not less than 150mm (3) the working medium is a liquid with gas, liquefied gas or temperature above the standard boiling point;
It is also the pressure vessel, the cylinder is more pressure, the cylinder pressure is lower. Need qualifications
In the hydraulic and pneumatic equipment, only the gas tank and the accumulator are the pressure vessel, the other solenoid valve, the oil cylinder, the cylinder is not the pressure vessel
Pressure is a sealed device that carries a certain amount of pressure Literally, oil cylinders, cylinders, and hydraulic components are not confined, they have A, P, and so on. So it's not a pressure vessel.
