RFL-1000 series laser

2. Power supply requirements: Three-phase AC380V Frequency: 50Hz

（1） Three-phase voltage stability ≤ ± 5%, three-phase power imbalance ≤2.5%

（2） The power supply uses a three-phase five-wire system and the grounding resistance is ≤ 4Ω;

（3） For switch specifications, wire cross sections, and connection methods used for machine tools, lasers, chillers, and air compressors, etc., refer to the machine power configuration diagram.

Note: ① The power supply voltage is not allowed to have sudden jumps and frequent sudden power failures;② If the grounding resistance cannot be guaranteed ≤ 4Ω, the grounding must be repeated. The method is to purchase 3 (1M / ground) ground rods of standard copper-plated steel core (copper-plated thickness of 0.25mm) with a size of about Ф18mm and bury them in the ground to a depth of about 2.5M.

3. Compressed air requirements:

（1） Air supply capacity: 1mL / min

（2） Air supply pressure: 0.8 ～ 1.0Mpa

（3） Dew point temperature is not higher than 5 ℃

（4） Oil content≤0.01ppm solid particles≤0.02μm

4. The ground requirements of the installation site: The ground is flat and clean, and the foundation is made according to the requirements on the foundation map; as shown in the contract

5. Environmental requirements for machine installation site:

（1） Temperature requirements: The machine tool can be placed in an environment of -10 ° C to 40 ° C; the laser must be placed in an environment of 18 ° C to 25 ° C; if it cannot be reached, a separate room and an air conditioner must be installed;

（2） Humidity requirement: ≤70% (laser only)

（3） Dust requirement: ≤1mg / m³, increase the exhaust dust fan.

6.The installation environment requirements of chiller, air compressor and freeze dryer:

（1） The cold-drying machine and air compressor can be placed outdoors. The surrounding environment must be dry, dust-free, rain-proof, etc. and the single water pipe between the water-cooling machine and the laser cannot exceed 10M;

（2） If the chiller, air compressor and freeze dryer are placed indoors, they must be dust-free and well ventilated, and the hot air generated by the chiller must be discharged outdoors;

7. Cutting gas requirements: The purity of the Cutting gas is based on the following gas purity. Customers can choose the purity of the gas according to the actual situation of the cutting effect:

Nitrogen: 99.7% (normal nitrogen or liquid nitrogen) Normal oxygen: 99.5% Pure oxygen: 99.95%

8. Cooling water requirements

（1） Deionized or distilled water must be used. If it cannot be replaced with barreled pure water, mineral water cannot be used, otherwise the life of the laser will be affected;

（2）In areas subject to freezing in winter, the chiller must be placed in an environment above 0 ℃.

9.Laser installation requirements

（1） When the laser is installed and hoisted, the laser tilt angle is less than 5 °;

（2） Peripheral space requirements of the laser: at least 1.5 meters of space around the laser, and the top space can allow 1 meter of space from the roof;

（3） Working environment temperature and humidity: The working environment temperature is 25 ℃ ± 2 ℃, the temperature fluctuation is small; the ambient humidity is less than 75%, and it will not condense and dew. Recommendation: If the customer's environment is poor, the laser must be in a separate room with air conditioning;

（4） Floor foundation requirements: floor load: floor load is greater than 1500kg, the floor must be flat and leveled, unevenness is less than 6mm

（5） There should be no equipment with excessive vibration around the laser, that is, the laser cannot be installed on the ground with vibration;

（6） Power requirements: Power supply requirements for customers' power grid 380 ± 10%, 50Hz, three-phase, neutral-to-ground; regulator output 380 ± 2%, 50Hz, three-phase, neutral-to-ground, 50KVA
