Gear pump pressure control is so important that a poor control algorithm for the pump can cause some variation in the extruder screw speed, causing large variations in the inlet pressure to the pump.
A gear pump is a common method to decrease the discharge pressure from the extruder, especially if the discharge pressure required by the die is relatively high. Temperature reduction and surge suppression are factors.
Screenchangers for blown film extrusion are continuous screen changers recommended for blown film filtration. A two bolt or piston design is usually preferred as shown in the following pictures.
Gear pump for compact rubber extruder adopts advanced cutting-edge extrusion technology, and consists of pump body, driving shaft, sliding bearing, front plate, and with labyrinth sealing.
Because as time development and the change of China's industrial, small specifications of the equipment began to slowly melt pump can't satisfy the production needs, large size gear pump equipment began to have been developed to meet the production requ
New energy industry economy is excellent, the polymer melt pump will be a major positive it?The answer is: definitely a major positive!
