1. Selection of the model size of the special chiller for the injection molding machine.
When used for cooling the mold of an injection molding machine, it can be calculated based on the injection volume of the injection molding machine. Generally, a 1HP water chiller is required for every 6 ounces of injection volume of the water chiller. For example, the customer’s factory is 100T (5.5OZS)×3 Units; 150T (12OZS)×4 units; 200T (23OZS)×3 units; the required chiller size is (5.5×3+12×4+23×3)/6=22.25, that is, a 25HP chiller . When used as cooling for other equipment, it depends on the specific flow rate of the cooling water circulation.
2. Selection of the heat preservation water tank and water pump of the chiller.
Sometimes according to the actual situation of the customer's factory, the box-type chiller may also require an external pump. At this time, the additional pump model must have the same power as the pump that comes with the chiller. If the 10HP box-type chiller comes with a pump power of 2HP, it must also be 2HP when the pump is added. The pump power requirement of the chiller is the same as that of the box-type chiller of the same model. The open-type chiller is connected to the external pump.
3. The temperature of the return water of the chiller should not be higher than 40 degrees. The higher the return water temperature, the greater the damage to the compressor.
