There are two ways to save energy in the laboratory.
1. Some energy-saving power, 2. Heating some energy-saving
Some energy-saving power: most of the choice of frequency converters, energy-saving method is to save the surplus energy of the motor, such as the actual power of the motor is 50Hz, and you need only 30Hz in production is enough, those remaining energy consumption is wasted, the inverter is to change the power output of the motor to achieve energy-saving effect.
Heating some energy-saving: heating some energy-saving is mostly using electromagnetic heater energy-saving, energy-saving rate is about 30% – 70% of the old resistance coil.
1. compared with the resistance heating, the electromagnetic heater has more than one insulation layer, and the utilization rate of heat energy is added.
2. Compared with resistance heating, electromagnetic heater acts directly on the material tube to reduce the heat transfer loss.
3. Compared with resistance heating, the heating speed of electromagnetic heater is more than a quarter faster and the heating time is reduced.
4. Compared with resistance heating, the heating speed of electromagnetic heater is faster, the output power is increased, and the motor is saturated, which reduces the power loss caused by high power and low demand.
Heating transformation of electromagnetic heating control cabinet for small size film blowing machine in laboratory
In the laboratory, the process of small blown film machine should be removed and some of the original heating rings of the barrel should be refitted. Measure the size of the barrel, usually including the perimeter length, check the need for insulation cotton and according to the original heating ring power budget winding direction is not enough. The insulation cotton is wrapped on the barrel and tied with high temperature yarn to keep the thickness of the insulation cotton around 1.5-2.0CM. In order to make the device more beautiful, an insulation resin sheet of 0.5mm can be wrapped on the insulation cotton. Surround the electromagnetic wire on the wrapped cartridge, and the electromagnetic wire around it should be as tight as possible. Installation of electromagnetic heating control cabinet.
