Applications
Arc spray machine is the metal spray equipment which can be used in :
1Anti corrosion coating of steel structure surface
2 Repair surface defects or processing errors of mechanical parts
3 Preparation of special surfaces for mechanical parts
4 Decorative coatings in iron industry
5 Quick completion of simple mould by spraying
6 Manufacturing metal powder
Main spraying materials: zinc, aluminum, Pb-Sn alloy, copper, carbon steel, stainless steel and other metals.
According to the production requirements of different working conditions, the spray gun can be fixed on the machine tool to spray regular large work pieces.
Equipment maintenance and precautions
The routine maintenance of arc spraying system is very important. Due to pollution and metal dust accumulation, it will produce wear and reduce the insulation strength and shorten the service life of the equipment. Therefore, the metal dust and dirt on the spray gun should be cleaned every shift. In addition, the following points should be noted.
1 The sprayer shall be placed in a place with small temperature difference, less dust, flat floor and dry ventilation and shall be protected from the sun, rain and small animals. Dust cover should be used when not in use.
2 Requirements for application range: the ambient temperature is from 10 ℃ below zero to 40 ℃ above zero, and the altitude is not more than 1500m.
3 It is strictly prohibited to shift gears when spraying. The DC output and cable joint shall be fixed firmly without looseness.
4 During the spraying operation, especially large current output occurs the voltage drop will be about 10%. This is a normal phenomenon, not a fault of the machine.
5 The short distance (within 10m) of AC power supply incoming line shall not be less than 4mm2, and when it is more than 10m, the incoming line shall not be less than 6 square millimetre.
6 Equipment grounding, power incoming line and cable insulation should be kept in good condition.
7 If any fault is found, it should be eliminated in time meanwhile changing the control and protection circuits is forbidden.
8 Turn on the main power switch and the fan should work normally. If not, cut off the power switch, otherwise the rectifier diode will be burnt out.
9 Pay attention to the wind direction during spraying procession and make sure that the equipment and people are in the upwind position.
10 Connect and unplug the four core connector for spray gun wire feeding, as shown in Figure 8. Align the slot position when connecting, do not push or pull to rotate so as to avoid damage.
11 If compressed air is ejected from the spray gun mouth, the two cables must have direct current. Please do not repair the spray gun at this time.
12When repairing spray gun or setting wire feeding voltage, please turn "spray gun working condition" switch S3 to "wire feeding".
13 The nozzle mouth should be checked after each installation of the spray gun. If two wires do not intersect well, it will be unfavorable for arc starting and unstable spraying.
14 During spraying procession, two wires must not collide behind the spray gun.
15 Clean regularly, use brush and dry compressed air to remove the dust on the components in the power box. If the environment is not good, please shorten the cleaning cycle.
16 The qualified electrical personnel should be invited for the maintenance of the equipment and the power supply should be cut off for the maintenance.
