As we all know, the cutting machine is a device that converts electrical energy to can, internal structure is complex, involving a combination of multiple disciplines and fields such as light, electricity, relative to other cutter while cutting machine for lower environmental requirements, but using the environment to meet the requirements, so that their own protective measures can play a protective role.
with the coming of winter, the cutting machine is facing the cold test.
Once the improper use, light affect the normal operation of the equipment, will affect the customer production schedule;
Or damage, and the cold water machine, to the customers cause unnecessary damage to property.
To avoid the above situation, asking customers to use cold water in winter, use must comply with the following considerations:
a using the environment temperature, cold water machine requirements must be above 0 ℃.
The main reason is to prevent due to environment temperature is too low,
Especially in the north)
Stop using, once the cold water machine, lead to the water system in water freeze, affect the normal use of equipment, serious word will make the whole refrigeration system damaged.
2, when the device using the environment temperature is in 0 ℃ to -
10 ℃, if the machine and cold water machine stop (
Such as electricity)
When work and not add antifreeze, must be timely to the water in the water system emptying, using compressed air or nitrogen (
Air pressure about 5 bar)
Will implement the internal emptying, manual will be cold water machine water pump and pipeline in the inland waters emptying.
Cold water machine in working condition is not caused by the equipment caused by freezing damage.
Requirements must be really empty water system (
Including the machine)
In the water.
Antifreeze is designated as '-
Clariant antifreeze Antifrogen N, coolant: deionized water is 1:2.
After adding antifreeze, can resist -
20 degrees Celsius and sea ice.
But because antifreeze has certain corrosion resistance, so please change back to normal after the winter of cooling water, and before cleaning the entire waterway, anti-icing fluid to clean clean;
3, cutting machine using the environment temperature is not less than 10 ℃ below zero.
4, drainage methods:
1, implement drainage method: disconnect the pipe, using compressed air or nitrogen (
Air pressure about 5 bar)
On the inlet and outlet water for about a minute, row to the best of water inside.
2 cistern drainage method: open drainage valve, tank bottom water tank of water, when it is necessary to tilt Angle, water-cooled machine to drain is low.
Drainage pipeline: use compressed air or nitrogen (
Air pressure about 5 bar)
From the low temperature water, high temperature water respectively for about a minute, by the water tank drain drainage.
Drainage pump pump: at the bottom of the each pump pump head on the water has a screw, when water captain time need downtime and transport, will open on the water head screw pump is put the water in the water pump, using compressed air or nitrogen (
Air pressure about 5 bar)
Blows completely, then drain screw.
Filters, ion water drainage: open the filter, a drain valve at the bottom of the tank to ion or organic glass shell can row the remaining water.
3, cutter machine drainage method: using compressed air in and out of the water for 2 minutes.
five, winter cold water machine check points and the solution:
1, the cooling water pump and start the chiller room temperature (
Outside the light path)
After the pump, check the cooling water pressure gauge and temperature of hydraulic pressure gauge readings.
If the pressure or flow alarm, must pay attention to whether waterway system did not open the valve or icy may, should be handled timely judgments.
If determined to be frozen, must promptly notify the manufacturer coordination treatment, do not solve itself!
2, after the normal operation of the pump, cooling water if the water temperature is lower than the machine allows the boot of low temperature, long time can't heat up.
Can set temperature of the cooling water and cold water is set high 5 ℃, other problems see instructions or notify the maintenance personnel, and finally must be set temperature of the cooling water and cold water are adjusted to the rules set temperature (
Set the temperature of the cooling water for 20 - commonly
Set temperature 25 ℃ and room temperature water for 25
35℃）
