What are the main reasons for power consumption of gas mold temperature machine?
announcer:

The mold temperature machine is composed of water tank, heating and cooling system, power transmission system, liquid level control system, temperature sensor, injection port and other devices. Normally, the pump in the power transmission system causes the hot fluid to reach the mold from the water tank equipped with a built-in heater and cooler, and then return to the water tank from the mold; the temperature sensor measures the temperature of the hot fluid and transmits the data to the control section. Controller; The controller regulates the temperature of the hot fluid, thereby indirectly regulating the temperature of the mold. If the mold temperature machine is in production and the mold temperature exceeds the set value of the controller, the controller will open the solenoid valve to connect the water inlet pipe until the temperature of the hot fluid, that is, the mold temperature returns to the set value. If the mold temperature is lower than the set value, the controller will turn on the heater.

The power consumption of the mold temperature machine is mainly generated by the electric heating and the oil pump, of which the electric heating is the main part. In the molding process, from the preheating of the mold temperature machine to the normal production of the later stage when the cold mold is turned on, the loss of electrical energy is mainly concentrated in the preheating part of the mold in the early stage, and the mold temperature machine is actually mainly in the later normal production. To cooling effect.

Because the higher heat brought into the mold at the beginning will cause the mold temperature to rise, in the later normal production, the heating part of the mold temperature machine only plays a role in temperature adjustment. It will not be in the heating state but in the heat preservation or cooling state. It is the normal circulation of oil pumps and high temperature oil pumps for some industries. It is recommended that customers choose Siemens as the main model when purchasing a mold temperature machine. Siemens' motor power is mainly 3HP (2.25KW) 5HP (3.75KW) dual machine integrated mold temperature Machine, the motor power is multiplied by 2, and the electrical energy adjusted by the heating power part will not have high electrical energy loss;

In addition, the frequent pull-in of the contactor of the mold temperature machine may cause the contactor to be stuck and cause constant heating. It may be recommended to choose to use a solid-state relay or thyristor control. As for causing a fire, it depends on whether the mold temperature machine manufacturer has made over-temperature protection measures, such as using over-temperature protection to reduce the possibility of fire if the whole machine is powered off after exceeding the set temperature.

How to calculate power consumption

There are two main power-consuming components of the mold temperature machine, one is the circulation pump, and the other is the electric heating tube. When the mold temperature machine is running normally, the circulating pump is always in working state, and its power consumption per hour is the pump power. For example, the working power of the pump is 1KW, and its power consumption is 1Kw/h. The electric heating tube is not always working. At the beginning of the heating up phase, the power consumption is the heating power of the electric heating tube. In the later stage of maintaining constant temperature, the power consumption is between 1/3~2/3 of the power of the electric heating tube. If economically allowed, it is recommended that the electric heating tube be controlled by thyristor, which can control the power consumption to a very small level.
