Detailed description of the structure and materials of the th

Thermoplastic extrusion melt pump is suitable for various extrusion industries, such as sheet, sheet, pipe, film, granulation, wire drawing, cable, co extrusion, mixing, precision extrusion, etc. The specifications and models of the extruder quantitative pump provided by the company range from 2CC to 8000CC, which can meet the needs of extrusion production lines with different yields.

thermoplastic melt pump structure of the extruder is mainly composed of a pump casing, front and rear side covers, gear shafts, sliding bearings, and shaft seals. Its main advantages are as follows:

1. Minimal pressure and flow pulsation can achieve linear output of flow, suitable for precision extrusion systems;

2. Adopting different structures and material configurations for different working conditions to better meet the personalized needs of users;

3. It can be applied to high temperature (350 ° C), pressure (40MPa), and high viscosity (40000 Paos) working conditions;

4. Precision structure, high precision, and long service life.

Material of thermoplastic hot melt pumps:

For the standard extrusion melt metering pump, the pump casing and gear are made of nitrided steel, and the bearing is made of Tool steel, which has good wear resistance, high toughness, and high cost performance, and is suitable for most working conditions with low abrasion. For the melt metering pump of the high wear resistant extruder, the pump shell is made of nitrided steel, and the gear and bearing are made of Tool steel, which has high strength and high wear resistance and is suitable for abrasive wear conditions. For the high corrosion resistant melt metering pump, the pump shell is made of stainless steel, and the gear and shaft sleeve are made of stainless Tool steel, which has high corrosion resistance and is suitable for high corrosive working conditions.
