Failure Analysis: > Aside from normal wear and tear, screw breakage typically results from forcefully starting the machine with insufficient preheating. This practice subjects the screw to excessive torque during startup, leading to the formation of micro-cracks. Over time, the accumulation of internal stress leads to fatigue failure and eventual breakage.
Operating Recommendations: > To ensure thorough plasticization and to protect the screw, it is recommended to set the temperature of all zones 20°C higher than the target production temperature during startup. Once the parison flows smoothly and operation stabilizes, adjust the temperatures back to the standard production values. This procedure effectively reduces startup resistance and eliminates the risk of breakage.
(1) It saves 40% more energy than traditional variable pumps and 60% more energy than traditional fixed-displacement pumps, thus reducing electricity costs.
(2) The longer the standby time during machine operation, the better the energy-saving effect.
(3) It effectively reduces hydraulic oil temperature, greatly extending the lifespan of hydraulic components and internal oil seals in hydraulic cylinders.
(4) Its low heat generation characteristic suppresses oil temperature rise and saves cooling costs, significantly reducing the frequency of hydraulic oil changes.
(5) The energy-saving servo motor system reduces oil consumption by 45% compared to traditional motors.
(6) The energy-saving servo motor adopts metering electronic control closed-loop control, which has a faster pressure and flow response speed than proportional pressure and flow control. It is particularly outstanding in pressure holding capacity and low-speed performance, achieving 100% efficiency within 0.01 seconds, resulting in high product precision.
(7) It has low noise when holding pressure, generally below 60 decibels, which is beneficial for long-term pressure holding operations.
(8) The energy-saving servo system simultaneously controls the pressure and flow of the variable capacity pump according to different operations, ensuring operation under optimal working conditions (such as low oil temperature and electronic feedback design), effectively extending the life and reliability of the servo motor.
