Coating knowledge: precautions for high pressure airless spraying pump

Core tip: the following requirements must be observed when using high-pressure airless spraying pump: 1 When spraying flammable coatings (such as nitrocellulose, etc.) with the ignition point below 21 ℃, the spraying pump and the sprayed object shall be grounded (connected to zero) The spraying pump shall not be placed in the same room for spraying operation 2 The special high-pressure hose for spray gun shall not be substituted arbitrarily The hose joint shall be made of conductive material with specified strength, and its maximum resistance shall not exceed 1m Ω 3 Before operation, check that the motor, electrical appliance and machine body are well grounded (connected to neutral), and check the suction hose, loop hose connector, pressure gauge and high-pressure soft Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: when using high pressure airless spraying pump, the following requirements must be observed: 1 When spraying flammable paint (such as nitrocellulose, etc.) with ignition point below 21 ℃, both the spraying pump and the sprayed object shall be grounded (connected to zero) The spraying pump shall not be placed in the same room for spraying operation 2 The special high-pressure hose for spray gun shall not be substituted arbitrarily The hose joint shall be made of conductive material with specified strength, and its maximum resistance shall not exceed 1m Ω 3 Before operation, check that the motor, electrical appliance and fuselage are well grounded (connected to neutral), and check that the suction hose, loop hose connector, pressure gauge, high-pressure hose and spray gun are firmly connected 4 No load operation shall be carried out before operation, then water or solvent shall be used for operation inspection, and operation can only be carried out after normal operation is confirmed 5 During the operation, the spray gun is strictly prohibited to touch people, and the sprayed paint shall not be touched by hands In case of spraying injury, it shall be sent to the hospital for treatment immediately 6 The minimum bending of high pressure hose during spraying shall not be less than 150 mm 7 When spraying is stopped in the workshop, the power supply shall be cut off, the safety lock of the spray gun shall be closed, the pressure shall be removed, and the spray gun shall be placed in the solvent barrel 8、 When the nozzle is blocked, the pressure shall be relieved first, the safety lock shall be closed, and then the nozzle shall be removed for cleaning When the nozzle hole is blocked, bamboo and wood shall be used instead of iron wire and other hard objects 9 When cleaning the spray gun, it is not allowed to spray the paint (especially the one whose ignition point is below 21 ℃) back into the closed dissolver Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
