What are the uses and characteristics of the reactor melt pump?
The reactor melt pump is suitable for conveying liquids with high viscosity and free from particulate impurities. It has the characteristics of high output pressure, high viscosity of the conveying medium, high operating temperature, vacuum input, convenient speed adjustment, and a large flow range. The material of the pump is temperature resistant, wear-resistant, corrosion-resistant, and has sufficient strength and dimensional stability.
Application scope of reaction kettle melt pump
(1) Applied in the polymerization reaction process to transport high viscosity melt.
(2) Applied to melt spinning, used as a booster pump.
(3) Applied to extruders or injection molding machines to improve extrusion efficiency and reduce extruder load.
(4) Applied to transport resin and melt resin, making the melt uniform and applying pressure to the mold head. The working principle of the ZB-F series melt pump belongs to the positive displacement pump, which relies on the meshing of the main and driven gears to cause changes in the working volume during operation to transport the melt.
The working volume is composed of the pump body, the gear teeth, and a bearing sleeve with side plate function. When the gear rotates, the melt enters the grooves of the two gears in the suction chamber. As it rotates, the melt is brought into the discharge chamber from both sides, and the gears mesh again, causing the melt in the grooves to be squeezed out of the discharge chamber and sent to the outlet pipeline. Bearings cannot use the usual lubricating grease to avoid contaminating the melt, and melt self-lubricating is usually used.
Melt pumps are mainly used for the transportation, pressurization, and metering of high-temperature and high viscosity polymer melts. Widely used abroad for extrusion molding of plastics, resins, rubber, and chemical fiber products. Industries such as granulation, film, pipe, sheet, sheet, artificial fiber, optical fiber, medical plastic catheters, etc. With the increasing development of the mechanical industry, melt pumps are gradually being adopted and applied by industry professionals in the domestic market.
The main function of the melt pump is to pressurize and stabilize the flow of high-temperature plastic melt from the extruder, and then feed it steadily into the extruder head. Its ability to stabilize melt pressure and flow rate is superior to various types of extruders. When used in series with a single screw or co rotating twin screw extruder, it significantly increases the efficiency of the entire production line.
