The water-type mold temperature controller is affected by the water quality, which causes the scale to adhere to the outer wall of the heating tube and the inner diameter of the pipeline for a long time, which affects the heating efficiency.
The oil-type mold temperature controller will coke due to the high temperature heating of the oil. If it is not cleaned for a long time, it will cause poor heat generation.
The phenomenon of dry burning is caused by misoperation. When the mold temperature machine is turned on, the motor and the electric heating tube are turned on at the same time, and the heating tube starts to work immediately. There is no heat transfer medium, which leads to direct dry burning, which works for a long time, shortens the service life of the heater, and makes the heater often easy to break.
In order to avoid the above phenomenon, the circuit board is designed with two buttons, namely the motor start button and the electric heating tube start button, which requires the operator to start the motor button first, wait for the water or heat transfer oil to be fully replenished, and then operate the heating tube button. , although this can prevent the heating tube from drying out, but because this operation needs to be done by people, and the operation is not very user-friendly, it needs to wait for a period of time before processing. Many operators often turn on two buttons at the same time for convenience, so as to achieve Without the intention of the mold temperature machine manufacturer's design, the heating tube cannot be protected.
In response to this problem, the mold temperature machine adopts the function of heating delay, that is, when the mold temperature machine is turned on, the unit first automatically replenishes the heat transfer medium such as water or heat transfer oil. A start signal, the heating pipe starts to work, thus preventing the heating pipe from dry burning. The unit is also equipped with a pressure controller. If the pressure is too low, it means that the flow of the heat transfer medium is insufficient, and dry burning may also occur. At this time, the unit starts to alarm, Through technical improvements in two aspects, the occurrence of the dry burning phenomenon of the heating pipe is solved from the root.
It is also necessary to pay attention to a problem that is easily overlooked. When the staff is about to get off work, the operator directly turns off the mold temperature machine for convenience. At this time, the surface temperature of the electric heating tube can reach 600-700 degree . When the heat medium is in contact with the heating pipe in a static state, the heat transfer medium will be adsorbed on the surface of the heating pipe, and the heating pipe will also be damaged for a long time. The most direct manifestation is that the heating rate of the mold temperature machine decreases.
