Screw extrusion melt pump is a kind of equipment used to transport melt medium, and its function and structure are different from traditional screw pumps. The role and structure of the screw extrusion melt pump will be detailed below.
The role of the screw extrusion melt pump.
1.Conveying the melt medium.
Screw extrusion melt pumps are mainly used to convey melt media, such as polymers, rubber, plastics, etc. These media melt easily at high temperatures, so screw extrusion melt pumps are required to guarantee their fluidity and conveying efficiency.
2.Stable flow and pressure.
Screw extrusion melt pumps provide a steady flow and pressure to meet the needs of different processes. The flow rate and pressure can be controlled by adjusting the speed and clearance of the screw to ensure the stable conveying of the medium.
3.Energy saving and environmental protection.
The screw extrusion melt pump adopts advanced energy-saving technology, which can reduce energy consumption and reduce environmental pollution. At the same time, its compact structure and small footprint make it easy to maintain and maintain.
Structure of a screw extrusion melt pump.
1.Pump body.
The pump body of the screw extrusion melt pump is made of cast iron or stainless steel, which has good corrosion and wear resistance. Inside it is installed a screw assembly and a sealing assembly.
2.Screw assembly.
The screw assembly is the core component of the screw extrusion melt pump, which consists of two screws arranged in parallel. The surface of the screw is hardened, which has high hardness and wear resistance. The screw rotates in opposite directions, thus creating a continuous conveyor channel.
3.Sealing components.
The sealing assembly is used to prevent leakage of media and consists of multiple sealing rings. The sealing ring is made of polymer material, which has good high temperature resistance, corrosion resistance and wear resistance. At the same time, the size and shape of the sealing ring are precisely calculated and designed to ensure its sealing performance.
4.Drives.
The drive of the screw extrusion melt pump is driven by an electric motor or hydraulic motor, and the power is transmitted to the screw assembly through a reducer. The drive unit has a speed regulation function, which can adjust the speed and clearance of the screw according to the needs of the process.
5.Safety protection device.
In order to ensure safe operation, the screw extrusion melt pump is equipped with safety protection devices. When the medium temperature is too high or the pressure is too high, the safety protection device will trigger an alarm or automatic shutdown to prevent equipment damage and accidents.
6.Control system.
The control system of the screw extrusion melt pump adopts advanced PLC or single-chip microcomputer control technology, which can monitor and adjust the operating status of the equipment in real time. The control system has the function of fault diagnosis, and can alarm and prompt the cause of the fault in time when the equipment fails. At the same time, the control system can also realize remote control and data transmission functions, which is convenient for users to carry out remote operation and maintenance.
In short, screw extrusion melt pump is an efficient, stable, energy-saving and environmentally friendly conveying equipment, which is widely used in the production process of plastics, rubber, polymers and other industries. Its function and structure are unique and advanced, which can meet the needs of different processes and ensure the normal operation of the equipment.
