Scope
Main technical content: This standard specifies the terms and definitions, product marking and composition, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and quality commitments of high-viscosity three-screw asphalt pumps with thermal insulation. This standard applies to high-viscosity three-screw asphalt pumps (hereinafter referred to as three-screw asphalt pumps) that can be heated by thermal oil or other high-temperature media through a thermal insulation jacket on the pump body, with a media temperature of (0~250)℃. They are used for transporting liquid asphalt at a flow rate of (3~1500) mm2/s under thermal insulation conditions.
