thermoplastic hot melt pumps: a secret weapon in the chemical
Melt gear pumps are mainly used in the chemical fields of polyester, chemical fibers, textiles, and plastics in China. In the production process of high viscosity polymers such as plastics or chemical fibers, melt gear pumps are usually used in conjunction with extruders to increase the pressure of the melt during the conveying process, effectively reducing the fluctuation and instability of the discharge.
thermoplastic hot melt pumps
The melt pressurization system introduced in polymer production lines usually consists of three parts: the thermoplastic extrusion pump head of the melt gear pump and the mechanical system driven by the reduction motor, the auxiliary heating control system, and the metering extrusion control system. The auxiliary heating is divided into insulation jacket and electric heating rod heating; The control system usually adopts PLC control mode, which can comprehensively control pressure, temperature, flow rate, etc. The optimized human-machine interaction interface can effectively ensure the smooth operation of the equipment; The pump body of the melt gear pump is the core of the entire system, and the material, sealing, and durability of the gear pump directly determine the stability and efficiency of production.
thermoplastic extrusion pump
The thermoplastic hot melt pumps is mainly composed of the pump body, master slave moving gears, sliding seals, and shaft seals. The working volume changes caused by the mutual meshing of the master slave moving gears to transport the melt or high viscosity melt. The gears mesh and rotate, and the melt is sucked in from the extrusion section of the kneading machine or extruder. The melt is pressurized and then extruded from the pump outlet, completing the pressurization, metering, and transportation of the melt.
