Five hazards of sudden temperature rise during equipment operation

During the use of the injection molding machine, the temperature will rise suddenly occasionally. Such a situation is also related to the weather temperature. In such a situation, it should be treated in time, which will reduce the harm to the equipment itself. Secondly, pay attention to some ways and methods when dealing with such accidents, If it is not handled properly, it is likely to aggravate the harm of the equipment. Here we take you to learn more about the five hazards of sudden temperature rise of the injection molding machine during use.

1、 Thermal deformation of machinery

The manufacturer of the injection molding machine tells you that the moving parts with different thermal expansion coefficients in the hydraulic components are stuck due to the smaller matching clearance, resulting in action failure, affecting the transmission accuracy of the hydraulic system, and deteriorating the working quality of the parts.

2、 Reduce the viscosity of the oil

Too high temperature rise of the injection molding machine will reduce the viscosity of the oil, increase the leakage, and significantly reduce the volumetric efficiency of the pump and the efficiency of the whole system. Due to the decrease of oil viscosity, the oil film of moving parts such as slide valve becomes thinner and cut, and the friction resistance increases, resulting in increased wear.

3、 Deform the rubber seal

The injection molding machine manufacturer tells you that too high temperature rise of the injection molding machine will deform the rubber seal, accelerate aging and failure, reduce the sealing performance and service life, and cause leakage.

4、 Accelerate the oxidative deterioration of oil

Too high temperature rise of the injection molding machine will accelerate the oxidation and deterioration of the oil, precipitate asphalt, and reduce the service life of the hydraulic oil. The precipitates block the damping small holes and crevice valve ports, resulting in the jamming and failure of the pressure valve, the elongation and bending of the metal pipeline, and even rupture of the pressure valve.

5、 Poor working quality of components

The manufacturer of the injection molding machine tells you that the high temperature rise of the injection molding machine will lead to the poor working quality of the parts, the escape of dissolved air in the oil and the generation of cavitation, resulting in the reduction of the working performance of the hydraulic system. The ideal working temperature of the hydraulic system should be between 45 ° C and 50 ° C. The reason is that the hydraulic system is designed according to the viscosity of a selected pressure oil, but the viscosity will change with the oil temperature, Then it affects the working components in the system, such as oil cylinder and hydraulic valve, and reduces the control accuracy and response sensitivity, especially for precision injection molding machine.

We suggest you read it in detail, which will be helpful for your later use. Secondly, regular maintenance and repair of the equipment can effectively reduce the occurrence of equipment failures. Thank you for your constant attention.
