High-Temperature Melt Metering Pump
The high-precision metering technology of the high-temperature melt metering pump serves as its core functional pillar. This technology is achieved through the synergy of precision structural design, premium material selection, and intelligent control systems. Key technical features include:
Precision Gear Design and Machining: Utilizes micron-level clearance high-precision meshing gear structures, strictly controlling melt flow error within ±1%. Select models feature mirror-finished gears to minimize material retention and enhance metering stability. Gears are crafted from high-temperature tool steel or chromium-nickel alloy steel, achieving a hardness of HRC 62-68 after through-hardening treatment. This ensures exceptional wear resistance and sustained metering precision throughout extended service life.
Intelligent Temperature Control and Pressure Stability: The pump body incorporates an external jacket and internal flow channels, enabling precise temperature regulation via cooling water or thermal fluid systems to prevent viscosity fluctuations caused by melt temperature variations. Combined with variable frequency speed control and a pressure feedback system, it dynamically adjusts rotational speed to compensate for pressure fluctuations from upstream equipment like extruders, achieving output pressure stability within ±0.5%.
High-Viscosity Material Compatibility: Designed for high-viscosity melts like rubber (up to 2000 Pa·s), the pump employs dual-shaft drive and specialized lubrication channels to ensure smooth conveyance and precise metering. Custom configurations are available, with flow rates spanning 0.1 cc to 12000 cc to accommodate diverse production requirements.
Industry Applications & Energy Efficiency: In precision manufacturing sectors like medical tubing and chemical fibers, high-precision metering ensures wall thickness tolerance ≤±1%, significantly reducing scrap rates. When integrated with extruders, it cuts energy consumption by 20%-30% while enhancing material mixing quality and production efficiency.
