POE granulation melt pump

POE (polyolefin elastomer) pelletizing melt pumps are specially designed for conveying, pressurizing and melt metering equipment for high temperature and high viscosity polymer melts such as POE. The following is a detailed analysis of POE pelletizing melt pump:

I. Equipment Overview

Function: POE pelletizing melt pump is mainly used for POE and other high-temperature, high-viscosity polymer melt conveying, pressurization and accurate metering to ensure stability and quality in the pelletizing process.

Features: compact structure, reliable operation, low energy consumption, high volumetric efficiency, small shear effect on the melt, able to maintain a stable flow under high viscosity and high pressure conditions, no outlet pressure fluctuations.

Second, the main parameters

Specification: The specification of the melt pump is usually expressed in terms of displacement per revolution, and the unit is usually cc (cubic centimeter). There is a wide range of specifications, the specific choice depends on the application scenario and demand.

Conveying capacity: directly related to the specifications, by adjusting the speed of the pump can be further adjusted to its output flow.

Pressure range: Output pressures can range from 0 to 40 MPa (or even higher), while suction pressures range from vacuum to a certain positive pressure, ensuring that they can cope with the demands of different process conditions.

Temperature range: The operating temperature range is usually wide, in order to adapt to the processing needs of different materials. Generally speaking, the operating temperature can be up to ≤ 400 ℃ (some say that ≤ 350 ℃), while the cleaning temperature can reach higher temperatures (such as ≤ 450 ℃).

Viscosity range: the viscosity of the medium can be transported a wide range, generally up to 1 ~ 4000Pa - s (there are also said to be up to higher viscosity).

Heating mode: including electric heating and thermal oil heating, can be selected according to the specific application scenarios and needs.

Sealing method: screw seal and packing seal are common sealing methods, which can effectively prevent melt leakage.

Third, the use of precautions

Installation and commissioning: pump body pump appearance are left with pressure sensor holes and temperature sensor holes, should be correctly installed sensors to avoid measurement data deviation. The pump body is connected with high strength bolts to ensure the safe operation of the pump body.

Starting and running: When the pump is first started, it should be run at low speed, and then gradually adjusted to the normal speed and pressure after the pump is running stably. If the pump does not rotate smoothly, the pump must be stopped to check the cause, so as to avoid serious internal damage to the pump.

Maintenance: Check the sealing status of the pump regularly. If packing seal is used, the position of the sealing cover should be adjusted frequently to maintain the best sealing status. At the same time, pay attention to the cleaning and lubrication of the pump to extend the service life.

Fourth, the field of application

POE pelletizing melt pump is widely used in the extrusion molding process of plastics, resins, rubber and other products, especially in POE and other high-temperature, high-viscosity polymer pelletizing process plays an important role. It can ensure the stability and quality of the extrusion molding process, improve production efficiency and product quality.

In summary, POE pelletizing melt pump is the key equipment for high-temperature and high-viscosity polymer melt conveying, pressurization and melt metering, which has a wide range of application prospects and important market value.
