Small electric high pressure cleaner safety specification1 ScopeThis standard specifies the safety requirements, signs, signs and instructions for small electric high pressure cleaners. This standard is applicable to the transportation medium which is mixed with normal temperature water or moving viscosity not more than 45mm2/s, free of particles and non-corrosive. Combined liquid, commercial and domestic small electric pressure washers for mobile and portable hand-held spray guns driven by electric motors (hereinafter referred to as washing machine). This standard does not apply to washing machines used in special environmental places, such as flammable, explosive, toxic and harmful gases and radioactive environments.2 Normative referencesThe following documents are indispensable for the application of this document.

Its rated discharge pressure is not less than 0.7MPa and is not large At 40MPa, rated flow is not more than 90L/min, motor power is not more than 15kW, current and voltage single phase does not exceed 250V, three-phase Not more than 480V. 3.2 Normal operation normal operation Follow the instructions in the manufacturer's instructions. Operating the machine under operating conditions, including but not limited to rated voltage, It is operated under rated flow and rated pressure conditions, and the inlet filter is in a clean state and suitable working environment. 3.3 Pressure relief unloading valve pressureregulatingunloadingvalve A valve that adjusts the pressure of the washer to a set value and remains stable. When the pressure exceeds the set value, the valve overflows part of the fluid back into the a port system or an external low pressure (eg atmospheric) environmental system; in addition, when the outlet flow is cut off (eg, the spray gun is turned off), it will pump the entire flow The overflow is returned to the inlet system or an external low pressure (eg atmospheric) environmental system to ensure that the pump pressure drops to a low pressure (usually close to zero pressure). ...... |
