Fuente de láser verde sólido Equipo láser Consejos de mantenimiento para el invierno

En el invierno, la temperatura está descendiendo. En este momento, no solo debemos calentarnos, sino también proteger contra congelamiento las máquinas láser para garantizar la vida útil del equipo y reducir el costo del riesgo.

Como todos sabemos, los líquidos tienen un “punto de congelación”. Cuando la temperatura del líquido es inferior a esta temperatura de "punto de congelación", se solidificará para formar un sólido, mientras que el agua desionizada o el agua destilada aumentarán de volumen durante la solidificación, lo que "romperá" el tubo láser de vidrio y sellará conexión. Para evitar el daño del tubo láser, el cabezal de salida y el enfriador de agua causado por la solidificación del líquido refrigerante, podemos resolverlo desde los siguientes tres aspectos:

Método 1

Para garantizar que el equipo láser en el entorno no se quede sin energía, no se puede apagar el enfriador de agua. Al mismo tiempo, en aras del ahorro de energía, ajuste la temperatura del agua a baja temperatura y temperatura normal a 5 ~ 10 ℃ para asegurarse de que el líquido refrigerante esté en estado de circulación y la temperatura no sea inferior al punto de congelación. .

Método 2

After the operation, the operator can empty the coolant  in the laser and the water chiller. (This method is tedious, it increases the workload, and there are cases where the staff forgets to empty and causes damage.)

Method 3

When use of the environment is often powered down and does not have the conditions to empty the coolant every day, antifreeze must be used. The base liquid of antifreeze is generally composed of alcohols and water, which requires high boiling point and flash point, high specific heat and conduction ability, low temperature viscosity, not easy to foam, not corrosive to metal parts, rubber hoses, etc. When selecting or preparing antifreeze, its freezing point should be about 5 ℃ lower than the minimum temperature of the use environment.

Use the special antifreeze instead of ethanol, glass water, etc. If the special antifreeze are not convenient to buy, you can also buy large bottled car antifreeze without adding water in a regular gas station or regular supply store for laser tube water cooling system.

Any antifreeze solution cannot completely replace deionized water and cannot be used for a long time throughout the year. After winter, the pipes must be cleaned with deionized water or distilled water, and the use of deionized water or distilled water as a coolant should be restored.

NOTES

(1) When the outside temperature is ≥5 ℃, confirm that there is no freezing, and you can directly adjust it to the startup state;

(2) When the outside temperature is less than 5 ℃, Please add cooling water and leave for a period of time, or use a warm air device to blow the internal pipes of the chiller for a period of time, confirm that there is no freezing, then turn on the device;

(3) Regardless of the working mode of the water chiller, the machine tool and laser (low voltage) need to be turned on to maintain water circulation and other auxiliary equipment can be turned off;

(4) If it has not been used for a long time, when the laser and chiller are started after adding water, if water flow alarm. Please use the exhaust hole of the pump to exhaust the water cycle, or restart the pump multiple times at 10-20 second intervals ;

(5) If the machine is stopped for a long time, the water tank should be emptied, and make deep clean air emptying processing.Simultaneously emptying the water pump and the water chiller filter.
