Why does the temperature control mould temperature rise slowly?

The mould 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 In general, the pump in the power transmission system makes the hot fluid reach the mould from the water tank with heater and cooler, and then return to the water tank from the mould The temperature sensor measures the temperature of the hot fluid and transmits the data to the controller of the control part The controller adjusts the temperature of the hot fluid to indirectly adjust the mold temperature If the temperature of the mold in production exceeds the temperature set by the controller, the controller will open the solenoid valve to connect the water inlet pipe until the temperature of the hot fluid and the temperature of the grinding tool return to the set value If the mold temperature is lower than the set value, the controller will turn on the heater Methods: the cause of the abnormal operation of the heating tube of the mould temperature machine was that the wiring of the heating tube was not good, or the coil was burnt out, which led to the slow heating of the mould temperature machine If it is a problem of heating pipe, it is necessary to measure the current to determine whether the heating pipe works normally If the heating pipe is burnt out, it is necessary to purchase a new heating pipe or contact the manufacturer for replacement There are scale or carbon deposition reasons for the mould temperature machine: no matter the water temperature machine or the oil temperature machine is used for a long time, if it is not cleaned, scale or carbon deposition will be attached to the inner wall of the heating pipe and pipeline, which will affect the heating efficiency and slow the temperature rise of the mould temperature machine, so the mould temperature machine needs to be cleaned in time The reason why the model temperature machine didn't choose the right power: another reason why the temperature of the model temperature machine was slowly rising was that the right power was not selected Generally, this situation will appear in the newly purchased model temperature machine The power of the mould temperature machine is simply the heating capacity of the mould temperature machine If a small power mould temperature machine is used to heat a large mould, the heating effect is not obvious Mold temperature machine is widely used in English plastic molding, die casting, rubber tire, roller, chemical reactor, bonding, internal mixing and other industries.
