JG/T 524-2017High-pressure airless spraying machine (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces JG/T 5018-1992 "High Pressure Airless Spraying Machine". The main technical changes compared to JG/T 5018-1992 are as follows.

--- Revised the scope of application of high pressure airless sprayer (see Chapter 1);

--- Updated some normative references (see Chapter 2);

--- Increased and revised terms related to high pressure airless spray technology (see Chapter 3);

--- Removed the main parameters and series of high pressure airless sprayer design (see Chapter 4);

--- Requirements for the degree of protection of electrical systems (5.1.11);

--- Re-requires the life of the suction valve (5.2.11).

This standard was proposed by the Institute of Standardization of the Ministry of Housing and Urban-Rural Development.

This standard is under the jurisdiction of the Building Construction Safety Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development.

3 Terms and definitions

Airless spray highpressureairlessspraying the high-pressure fluid medium is instantaneously ejected through the conveying system, the spray gun, and the nozzle, and rapidly expands and atomizes to shoot the coating surface to form a coating.

Construction equipment that uses the principle of high pressure airless spraying.

Rated working pressure ratedcapacity the allowable pressure at the pump outlet when the sprayer is in operation.

Note. The unit is MPa.

Rated flow the volume of fluid medium that can be pumped per unit of time at rated pressure.

Note. The unit is L/min.

Maximum flow Stable flow rate of the spray gun nozzle when the spray gun is not equipped with a nozzle.

Note. The unit is L/min.
