喷枪的维护
Maintenance of spray gun
最好每天工作完后进行润滑喷枪，用轻机润滑的各部件。由于正常的磨损和老化，密封圈、弹簧、针阀和喷嘴必须定期更换。更换应按生产厂家的说时进行。由于机油过量就会流入涂料和机油通道，造成喷涂缺陷，因此润滑时必须非常小心，机油和涂料混合后就会降低喷涂质量。
It is better to lubricate the spray gun every day after work, and use light machine to lubricate the parts. Due to normal wear and aging, the sealing ring, spring, needle valve and nozzle must be replaced regularly. Replacement shall be carried out according to the manufacturer's instructions. Due to excessive oil will flow into the coating and oil channel, resulting in spraying defects, so you must be very careful when lubricating, oil and paint mixed will reduce the quality of spraying.
不要把整把喷枪长时间泡在清洗液中，这样会使密封圈硬化，并破坏润滑效果。
Do not soak the whole spray gun in the cleaning solution for a long time, which will harden the sealing ring and damage the lubrication effect.
为了获得最佳的修补效果，在不同的涂层和情况下要使用不同的喷枪。建议每人配备四把喷枪，一把用于底漆、中涂层喷涂，一把用于面漆、清漆层喷涂，一把用于银粉漆喷涂，还有一把小修补喷枪用于点修补时使用。如果，这些喷枪保持良好的清洗和工作须序，就会节省大量换枪时的调整和清洗时间。
In order to obtain the best repair effect, different spray guns should be used in different coatings and situations. It is suggested that each person should be equipped with four spray guns, one for primer and intermediate coat spraying, one for topcoat and varnish coating spraying, one for silver paint spraying, and one for spot repair. If these spray guns are kept in good cleaning and working order, it will save a lot of adjustment and cleaning time when changing guns.
