With the rapid development of machinery industry, vertical injection molding machine
in the field has become the necessary processing machinery plastic factory, and now the injection molding machine application is more and more widely, but the vertical injection molding machine brings us a efficient work at the same time also want to know what it bring us harm, so as to achieve the safety of the use of injection molding machine efficient work and safety production.
Vertical injection molding machine high temperature rise five hazards: make the machinery to produce hot deformation, oil viscosity, the deformation of rubber seals, accelerating the oil oxidation, but also make the air component of the pressure drop.
To produce hot deformation mechanical hydraulic components in the thermal expansion coefficient of different moving parts due to its smaller fit clearance and stuck, cause action failure, affect the hydraulic system of transmission precision, deterioration in quality parts work.
Reduce the viscosity of the oil injection molding machine high temperature will lead to the oil viscosity is reduced, leakage increase, the volume of the pump efficiency and the efficiency of the whole system will be significantly reduced.
As a result of the oil viscosity is reduced, valve and other moving parts of the oil film thinning and cut broken, frictional resistance increases, lead to wear and tear.
Make the rubber seal deformation injection molding machine high temperature can make the rubber seals, accelerated aging failure, reduce the sealing performance and using life, cause leakage.
To speed up the oil oxidation injection molding machine high temperature rise will accelerate the oil oxidation, precipitation asphalt material, reduce the service life of hydraulic oil.
Precipitates jam the damping holes and cracks type valve, causing pressure valve stuck and cannot move, metal pipeline elongation and bending, and even rupture.
Deterioration in parts work quality vertical injection molding machine high temperature can cause parts work quality, air dissolved in transformer oil escape, produce cavitation, the working performance of hydraulic system.
Hydraulic system of the ideal working temperature should be between 45 to 50 degrees, the reason is that the hydraulic system is designed based on a selected pressure oil viscosity, but viscosity changes with the discretion of the oil temperature, thus affecting work of the system components, such as oil cylinder, hydraulic valve, the control accuracy and response sensitivity is reduced, especially in the case of precision injection machine.
High temperature at the same time also will accelerate the seals aging makes its hardening, fracture;
Temperature is too low processing and energy consumption, lower the running speed.
So pay close attention to the working temperature of hydraulic oil is very necessary.
High oil temperature has a variety of causes, but more due to hydraulic failure or the failure of the cooling system, etc.
According to different load requirements, check and adjust the pressure relief valve, make it right.
Choose the hydraulic oil, especially oil viscosity, in conditions allow, as far as possible with lower viscosity in order to reduce viscosity friction loss.
Improve the lubrication conditions of moving parts, in order to reduce friction loss, is helpful to reduce the work load, reduce fever.
Improve the assembly quality of hydraulic components and hydraulic system and its accuracy, strictly control the mating parts fit clearance and improve the lubrication conditions.
USES the friction coefficient of sealing materials and improving the seal structure, reduce the starting force of hydraulic cylinder, as far as possible in order to reduce the heat generated by the mechanical friction loss.
