Please tell me the reason for choosing this tonnageFor example, an injection molding machine, water flow of 4 tons per hour, then 4 units on the election of 20T cooling tower is not enough? 20T's cooling water flow is about 18 cubic meters per hour
The cooling water machine 160T~200T injection dosage of 160T~200T injection molding machine cooling water consumption is 4.2 m fand /H, you have 4, that is 16.8m /H this is fand regardless of your water, cold water machine, injection molding machine, mold temperature and water machine water situation. Personal advice, buy a water tower, you can buy a little larger, and if you want to increase the machine later, the water tower is small, then you have to change. At the moment, it's okay to pick a big water tower (big, cool, better, too big to waste), and 20t's water tower and 30t's water tower don't cost much (about 600~900)20t traffic to 15.62m /H fand tower25t traffic to 19.51m /H fand tower30t traffic to 23.4m /H fand tower
In general we 160T mold, pipe size of 16MM-20MM in diameter, but in general we pump flow rate Straw at 2 m / S (injection cooling water is recycled, water pump Straw flow is the decision point need air conditioning cooling tower), so we can assume that the size of pipe diameter is 20MM, the water flow rate of 2 meters so every hour per second; each injection molding machine needs the amount of water:PI (0.01 meters) * (0.01 meters) *2 M / s *3600 s =2.26 cubic metersYou do this, and here you should be clear! In addition, individuals feel that there is still need to consider whether the subsequent expansion of production, that is, increase the number of injection molding machine, so personally feel that the need to reserve space as well!
The cooling water machine 160T~200T injection dosage of 160T~200T injection molding machine cooling water consumption is 4.2 m fand /H.4, it is 16.8m /H that is not considered fand, injection molding machine mold water chiller, water and water machine water situation.A proposal to buy water tower could buy, if continued to increase the machine, it would have to change a small tower, currently selected tower selected points (nothing big cooling effect is better, too much waste), and the 20t tower and 30t tower much money.20t traffic to 15.62m /H fand tower25t traffic to 19.51m /H fand tower30t traffic to 23.4m /H fand tower
