Safety Specifications for High-Pressure Water Jet Cleaning Operations1 ScopeThis document specifies the composition and requirements of the operation team for high-pressure water jet cleaning operations, pre-operation preparation, operating procedures and equipment maintenance. This document is applicable to high-pressure water jet cleaning operations with a pressure of not less than 10 MPa, and water jet mobile cutting and crushing operations. implement.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document. GB 14866 General technical specification for eye and face protection GB/T 41513 Classification and terminology of spray equipment AQ 3018 General safety rules for hazardous chemical storage tank area operations AQ 3026 Safety Specifications for Equipment Maintenance Operations in Chemical Production Units HG 30010 Safety regulations for hot work in production areas HG 30011 Safety Specifications for Confined Space Operations in Production Areas HG 30013 Safety Specifications for Working at Heights in Production Areas3 Terms and definitionsThe terms and definitions defined in GB/T 41513 and the following apply to this document. 3.1 High pressure pump The working pressure is between 10 MPa and 100 MPa. It is a pressure source device used to increase the water pressure and deliver the high-pressure water to the nozzle. Note. High pressure pumps are often of positive displacement piston type to ensure a constant flow rate at a given pump speed. 3.2 spray gun A handheld cleaning tool that controls high-pressure water through a nozzle to form a water jet. Note 1.It consists of a control valve, a spray bar and a nozzle assembly (including one or more nozzles), and the spray gun locking mechanism is shown in Figure 1. Note 2.The spray gun is usually connected to the pressure regulating valve at the discharge end of the high-pressure pump through a high-pressure hose assembly. Note 3.Spray guns can be classified according to the type of control valve. if the system drops to normal pressure when the valve is closed and the high-pressure water is discharged to the atmosphere, it is a unloading type spray gun; if the valve When closed, high pressure water remains in the system, which is a shut-off type spray gun.
