Preventive maintenance and repai1 hydraulic oil quantity shortage will cause the oil temperature, easy to dissolve the oil Yi Shenggao air and affect the normal work of the oil and hydraulic system, lacking of oil spill or repair is usually caused by the loss, therefore daily should pay attention to check there is no parts of the leakage, seal to replace worn, tighten loose joints, after the repair to check the oil quantity in oil tank, timely supply.
2.The ideal working temperature of 2 hydraulic oil temperature of hydraulic system should be between 450C and 500C, the reason is the hydraulic system is designed according to a selected pressure oil viscosity, but the viscosity changes with the temperature level, thereby affecting the component in the system, such as cylinder, hydraulic valve, so that the control precision and response sensitivity reduction for precision injection machine, particularly. At the same time, the temperature is too high will also accelerate the aging hardening, sealing it fragmented parts; the temperature is too low processing energy consumption, reduce the speed. So pay close attention to the working temperature of the hydraulic oil is very necessary. The reason of over high temperature of diversity, but to the circuit fault or failure of the cooling systems etc..
Injection molding machine, injection molding machine or injection machine. It is the main forming equipment plastic products, thermoplastic or thermosetting plastics using plastic molding into various shapes. Divided into vertical, horizontal, all electric. The function of heating plastic injection, high voltage is applied to the molten plastic, so that the injection and full of mold cavity
