The second is the vertical injection molding machine manufacturer's motor. Usually, electric motors are air-cooled. The accumulation of dust will make it difficult to dissipate heat, so regular cleaning should be carried out every year. The current limit of the protection device is adjustable. Appropriate selection should be made based on the power of the motor. At the same time, once the overload protection device is activated, please check whether the contacts are damaged or the oil temperature is too high before pressing the reset switch.household plastic mold.
Then there are heating tubes and thermocouples. Regularly check the fastening of the heating pipes to ensure effective heat transfer. In normal production, it is not easy to detect the combustion of the heating tube. Therefore, it is necessary to pay attention to the working condition of the temperature control area to judge whether the heating pipe is normal. In addition, the common damage to heating pipes is the connection of wires. Due to poor joints and increased contact resistance, the local overheating of the connection can lead to interface oxidation and damage. Therefore, it is necessary to keep the thermocouple contact points clean.plastic spoon machine.
Vertical injection molding machine and AC contactor. The contactor used for the electric heating part has frequent operating time and fast loss speed. If the main contact overheats and melts, the heating temperature may become out of control. Therefore, if the contactor is found to be overheated, making noise or damaging large sparks, it should be damaged and replaced as soon as possible.precision core parts.
Microcomputer control part. With the application of microcomputer control technology in injection molding machines, the normal working voltage fluctuations of computer components and related auxiliary versions of power supply, working environment of temperature and humidity, seismic installation, and high frequency signals from external interference are required. Therefore, please maintain control over cabinet ventilation and heat dissipation, use high-precision power supply voltage stabilizing equipment, and minimize the impact of external vibration on the control box. It is a basic requirement for normal work, and these issues should be addressed and regularly inspected.
