2024-03-14 Explanation of friction bearing technology for melt metering pumps
Bearings are one of the core components of melt metering pumps. Materials and designs must be carefully selected and coordinated to ensure the safe and efficient operation of the metering pump. Usually, friction bearings are used for melt pump for extrusion. For this type of bearing, the inner diameter is slightly larger than the journal stored inside. The transported medium seeps into this small area through the lubrication groove, and through the lubrication groove, the medium in the bearing forms a hydrodynamic lubrication film. The shaft floats in the bearing. For friction bearings lubrica
2024-03-11 High temperature melt pump application, parameters and internal structure
High-temperature melt pumps are mainly used for transporting, pressurizing, and metering high-temperature and high-viscosity polymer melts. It has the characteristics of compact structure, reliable operation, low energy consumption, high volumetric efficiency, and small shearing effect on the melt. High-temperature melt pumps are usually used together with extruders in plastic processing. They can further homogenize the melt, provide stable flow at high temperatures and high pressures, no pulsation in material output, high volumetric efficiency, and small shearing effect on the melt. Thereby i
2024-03-07 What are the technical parameters of a high-temperature melt pump
The main technical parameters of a high-temperature melt pump include displacement, working temperature, working pressure, speed, torque, and driving power. Usually, the displacement, working temperature, and working pressure are clearly marked on the product of the high-temperature melt gear pump to indicate its conveying and boosting capacity. When selecting a high-temperature melt pump, multiply the displacement by the pump speed, volumetric efficiency, and melt density to see if the expected large output can be achieved. Choosing a small displacement melt pump has better economy, but the m
2024-03-04 How does the melt pump work?
The melt pump belongs to a positive displacement pump, which relies on the change in working volume caused by the meshing of the main and driven shafts to transport the melt during operation. The working volume is composed of the pump body, gear teeth, and bearings with side plate function. When the gears rotate, the melt enters the grooves of the two gears in the suction chamber. As the gears rotate, the melt is brought into the discharge chamber from both sides. The re meshing of the gears causes the melt in the grooves to be squeezed out of the discharge chamber and sent to the outlet pipel
2024-03-02 What are the steps for inspecting the melt pump of the extruder during the turning process?
1. Before heating the extruder melt pump, manually rotate the pump shaft in both forward and reverse directions (allowing for turning from the rear of the motor) at least once. The extruder melt pump should rotate flexibly, without jamming, abnormal noise, and vibration. 2. After the extruder melt pump heats up, manually turn it in both forward and reverse directions (allowing it to be turned from the rear of the motor), and rotate the pump shaft in both directions for at least one revolution. The extruder melt gear pump should rotate flexibly, without jamming, abnormal noise, and vibration. 3
