What is special equipment? What are the categories of special equipment?

Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipes, elevators, lifting machinery, passenger ropeways, large amusement facilities and special motor vehicles in the field (factory) which are related to life safety and great danger. Among them, boilers, pressure vessels (including gas cylinders) and pressure pipelines belong to pressure-bearing special equipment; Elevator, hoisting machinery, passenger ropeway and large amusement facilities belong to electromechanical special equipment.

Classification of special equipment

Pressure bearing special equipment

(1) boiler refers to the equipment that uses various fuels, electricity or other energy sources to heat the liquid to a certain parameter and provide heat energy in the form of external output medium. Its scope is defined as a pressurized steam boiler with a designed normal water level volume of 30L or more and a rated steam pressure of 0. 1MPa (gauge pressure) or more; Pressurized hot water boiler with outlet water pressure greater than or equal to 0. 1 MPa (gauge pressure) and rated power greater than or equal to 0. 1 MW; Organic heat carrier boiler with rated power greater than or equal to 0. 1MW.

(2) The pressure vessel refers to the closed equipment that contains gas or liquid and bears a certain pressure, and its scope is defined as the gas with the highest working pressure greater than or equal to 0. 1MPa (gauge pressure), the liquefied gas and liquid with the highest working temperature greater than or equal to the standard boiling point, and the fixed type with the volume greater than or equal to 30L and the inner diameter (the largest geometric dimension of the inner boundary of a non-circular cross section) greater than or equal to 150mm. Gas cylinders containing gas with nominal working pressure greater than or equal to 0.2 MPa (gauge pressure) and product of pressure and volume greater than or equal to 1.0 MPa L, liquefied gas and liquid with standard boiling point equal to or lower than 60℃; Oxygen chamber.

(3) Pressure pipeline refers to the tubular equipment used to transport gas or liquid under a certain pressure, and its scope is defined as that the maximum working pressure is greater than or equal to 0. 1MPa (gauge pressure), the medium is gas, liquefied gas, steam or flammable, explosive, toxic and corrosive liquid, and the maximum working temperature is greater than or equal to the standard boiling point. Pipes with a nominal diameter greater than or equal to 50 mm ... Except for pipelines conveying nontoxic, incombustible and corrosive gases and pipelines belonging to the equipment body, the nominal diameter is less than 150mm, and the maximum working pressure is less than 1.6MPa (gauge pressure). Among them, the safety supervision and management of oil and gas pipelines should also be implemented in accordance with the Safety Production Law, the Oil and Gas Pipeline Protection Law and other laws and regulations.

Electromechanical special equipment

(1) Elevator refers to the electromechanical equipment driven by power, which uses boxes running along rigid guide rails or steps running along fixed lines to lift or transport people and goods in parallel, including manned (cargo) elevators, escalators and moving sidewalks. Except for elevators installed in non-public places and used only by a single family.

(2) Lifting machinery refers to mechanical and electrical equipment used for vertical lifting or vertical lifting and horizontal moving of heavy objects, and its scope is defined as elevators with rated lifting weight greater than or equal to 0.5t; Crane with rated lifting capacity greater than or equal to 3t (or tower crane with rated lifting torque greater than or equal to 40t·m, or loading and unloading bridge with productivity greater than or equal to 300t/h) and lifting height greater than or equal to 2m; Two or more floors of mechanical parking equipment.

(3) Passenger ropeway refers to mechanical and electrical equipment that uses flexible ropes to pull boxes and other vehicles to transport people, including passenger aerial ropeway, passenger cable car and passenger traction ropeway. Except for non-public passenger ropeways and special passenger ropeways for commuting within the unit.

(4) Large-scale amusement facilities refer to facilities for carrying passengers for business purposes, and their scope is defined as large-scale amusement facilities with manned passengers whose designed maximum running linear speed is more than or equal to 2m/s, or whose running height is more than or equal to 2m from the ground. Except for large-scale entertainment facilities used for sports, cultural performances and non-business activities.

(5) Special motor vehicles in the field (factory) refer to special motor vehicles that are only used in specific areas such as the factory, tourist attractions and amusement places, except road traffic and agricultural vehicles.
