Winter Antifreeze Protection Measures For Fiber Laser

Fiber laser is a new type of fiber laser that is newly developed in the world. It outputs high-energy-density laser beam, which is concentrated on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized, and the spot is moved by the numerical control mechanical system. Realize automatic cutting by irradiating position, fast speed and high precision.

Fiber laser: It is the core component of fiber laser cutting machine 1000w, and it is also the “power source” for fiber laser cutting machine to realize cutting operation. Compared with other types of lasers, fiber lasers have the advantages of higher efficiency, longer service life, less maintenance, and lower cost.

1. The water temperature setting of the chiller should be set with the change of the ambient temperature. The water temperature setting range in winter is 22°C-25°C, and the water temperature setting range in summer is 27°C-30°C. Appropriate water temperature setting can reduce the alarm and save the humidity and temperature of the laser. Use electricity while avoiding condensation on the laser and laser cutting head.

2. When the ambient temperature is lower than 0 °C, the liquid water will condense to form a solid, and during the condensation process, the volume will become larger. In this way, the pipes and components (including chillers, lasers and laser cutting heads) in the water-cooling system will be “cracked”, or the pipes in the water-cooling system will be blocked, so that the cooling water cannot be circulated, and the equipment cannot be used normally.

The antifreeze protection measures for equipment used in winter are as follows:

1. If there will never be a power outage in the local area, the chiller will not be turned off when the equipment is out of use.

2. If the equipment must be powered off or the water cooler will not be used for a long time (such as the Spring Festival holiday), all the cooling circulating water should be drained (including the water tank of the chiller, water pipes, lasers, and cooling water inside the cutting head). When there is a small amount of cooling circulating water that cannot be exhausted, it is necessary to pass low-pressure air (air pressure should not be greater than 0.4MPa) to drain all remaining water to prevent freezing, or add antifreeze according to the requirements of Article 3.

3. When the use environment is often powered off and does not have the conditions to drain the cooling water every day, professional brand antifreeze must be used. When adding antifreeze, it is necessary to empty the cooling water in all pipes and components in the cold water system, and then mix the antifreeze and cooling water in a certain proportion and pour them into the chiller (remember not to inject separately). For different brands of antifreeze and water freezing point, please consult professional manufacturers. The following table is an example of the freezing point of Clariant antifreeze water. If the ambient temperature is lower than this range, please consult a professional manufacturer to confirm the antifreeze ratio.

The fiber laser must be operated in safe and reliable conditions. The safety regulations are as follows:

1, The laser has a negative impact on the human body, in the course of the operation to protect the weak parts of the body,such as eyes, exposed skin, etc., should not look directly with the eyes of the laser Cut.

2, The operation process, any part of the body can not be in the runway within the beam, to avoid being bruised.

3, In the course of operation, can not open the laser, fuselage, chiller circuit control cabinet, to prevent high-voltage electrical harm to the human body.

4, fiber laser 1000w must be shut down before the maintenance of power, to be completed before the power test.

5, The cylinder near the point of storage can not have any flammable material, can not have a fire source.

Must operate in the following order:

1, The total power supply. Check whether the power supply voltage and the three-phase balance meet the power requirements of the machine.

2,Start the chiller. Check the water temperature, water pressure is working properly.

3,Open the compressed air, check the air pressure is normal.

4, Check the nitrogen / oxygen, check the cylinder pressure, low pressure is normal; if the high pressure below 0.6Mpa, will have to replace the cylinder.

5,Start the laser.

6, The control system power. The machine back to zero, so that the machine into the standby state.

7, Enter the work piece processing program.

8,Open the auxiliary gas, and according to the different processing materials, adjust the air pressure. The auxiliary gas of the gas-electric converter should be adjusted in place to ensure that the air pressure is below a certain value when the cutting is stopped to ensure the safety of the focus lens.

9, On the material. Care should be taken to ensure the safety of life and to avoid bruising the machine.

10, Start the program for processing. Processing process should always pay attention to cutting the situation, if the cutting head through the empty situation to immediately stop, remove the fault factors, to continue cutting.
