FAQ
Q1: What are the main advantages of this servo pump set compared to my current fixed-displacement pump + asynchronous motor system on the injection molding machine?
A: The core advantages are extremely high energy efficiency, superior control precision, and significantly reduced operating noise.
● Energy Saving up to 50-80%: Traditional fixed pumps run constantly at max pressure/flow, wasting excess energy via relief valves. The servo pump set delivers precise flow/pressure on demand, with minimal waste.
●Improved Product Quality: More stable pressure and faster response enable more precise control over injection and holding phases, reducing defects.
● Reduced Oil Temperature: Less energy waste means significantly lower hydraulic oil temperature, extending the life of oil and seals.
Q2: Can this servo pump set directly replace the existing hydraulic power system on my injection molding machine? Is the installation complicated?
A: Yes, this is a complete drop-in replacement solution. The installation process is standardized, primarily involving:
●Mechanical Installation: Mounting the pump set to the original location via a bracket and connecting pump ports to existing high-pressure lines.
●Electrical Connection: Connecting the servo drive to the main power supply and signal lines (pressure/flow commands) to the injection molding machine’s control system.
Q3: Is the maintenance cost of the servo system higher than that of a traditional system?
A: Actually, the overall maintenance cost is typically lower. The reasons are:
●Extended Hydraulic Oil Life: Significantly reduced oil temperature slows oxidation, greatly extending the replacement intervals for hydraulic oil and filters.
●Reduced Component Stress: The system no longer requires long-term high-pressure relief, reducing fatigue on pumps, valves, and fittings.
●High Reliability: Sumitomo internal gear pumps are known for their durability, and servo motors have no wear-prone components like brushes. The main maintenance task is keeping the hydraulic oil clean.
