the Temperature and Pressure Control of High Temperature Melt Gear Pump

the Background of high temperature melt gear pump

Due to the nature of the plastic extrusion process, the material must be guaranteed to be delivered to the extruder head under high pressure. With the development of the machinery industry, melt pumps are gradually being adopted by the industry people in the domestic market. ZB series of high-temperature melt pump is used in the plastic extrusion industry, used to stabilize the pressure and improve extrusion output and product quality.

High temperature melt gear pump is mainly used for high temperature and high viscosity polymer melt delivery, pressurization, measurement. Foreign widely used in plastics, resins, rubber products, extrusion molding. Such as: granulation, film, pipe, sheet, sheet and other industries. High-temperature plastic melt delivered by the extruder is pressurized by a gear pump and regulated to the extruder head. The use of high-temperature melt gear pump can increase the stability of the pressure, the realization of the fundamental is the use of inverter technology to control the motor speed, in order to achieve pressure, pressure control. This means that only the pump start-up conditions, the pump inlet and outlet temperature, pressure, effective control, in order to achieve continuous, steady process requirements. Because for the gear pump, come in the temperature of raw materials is very important for the transmission of gear pump, the temperature is too low will affect the pump transmission, and the pump inlet and outlet pressure control can greatly improve product uniformity. Making the product size error and behavioral errors are effectively controlled within tight tolerances, product quality can be well guaranteed. Can be seen on the import and export of hot melt gear pump temperature and pressure control is crucial.
