Special reminder: Please always beware of the various hazards brought by high temperature to plastic processing equipment

When you use plastic processing equipment for plastic processing, you should remember to observe the temperature carefully, because if the temperature of plastic processing equipment is too high, it will cause many hazards to the equipment. Therefore, in order to ensure the normal use of the equipment, you should avoid the phenomenon of too high temperature of plastic processing equipment, Let’s learn how to avoid excessive temperature of processing equipment.

▼ cause thermal deformation of the machine. The moving components with different thermal expansion coefficients in the hydraulic components are stuck due to their small apprenticeship, resulting in faults, affecting the transmission accuracy of the hydraulic system and poor working quality of the components.

▼ cause the viscosity of the oil to decrease. If the temperature of the plastic processing equipment is too high, the viscosity of the oil will be reduced, the leakage will increase, and the volumetric efficiency of the pump and the efficiency of the whole system will be significantly reduced. As the viscosity of the oil decreases, the oil film of a moving member such as a spool becomes thinner and cut, and the friction resistance increases, resulting in increased wear.

▼ change the shape of the rubber sealing ring. Too high temperature of plastic processing equipment will lead to deformation of rubber seals, accelerate aging failure, reduce sealing performance, lead to service time and cause leakage.

▼ accelerate oil oxidation and deterioration. If the temperature of plastic processing equipment rises too high, it will accelerate the oxidation and deterioration of oil, precipitate asphalt materials and reduce the delivery time of hydraulic oil. Sediment blocks the damper orifice and slit valve port, causing the pressure valve to be stuck without actuation, and the metal pipe to be elongated, bent or even broken.

▼ the quality of component work decreases. If the temperature of the plastic processing equipment rises too high, the working quality of the components will be reduced, the dissolved air in the oil will escape, and cavitation will occur, resulting in the reduction of the working performance of the hydraulic system.

General plastic processing equipment shall also carry out daily spot inspection, patrol inspection, regular inspection (including accuracy inspection), integrity inspection, etc. through human senses and general detection tools, focusing on mastering the technical status and abnormal phenomenon information of parts, mechanisms and parts prone to failure. At the same time, inspection standards shall be formulated to determine the limits of normal, abnormal and fault of plastic processing equipment.
