The extruder melt pump is a kind of equipment commonly used in the production process of plastics, rubber and other industries, which can evenly and stably convey the plastic or rubber materials in a high-temperature molten state to the barrel of the extruder through rotation or reciprocating motion, so as to control the quality and output of the product. This article will provide detailed instructions for the use of extruder melt pumps to help you better understand and use this equipment.
1. The structure and working principle of the extruder melt pump.
The extruder melt pump is composed of a pump body, a rotor, a seal, a bearing and a transmission device. It works by using a rotating rotor to suck a molten plastic or rubber material into the pump chamber, and then through the gap between the stator and the rotor, the material is conveyed to the outlet end. During the conveying process, the melt pump keeps the material in a molten state through the control of pressure and temperature, and ensures its uniformity and stability.
2. Installation and commissioning of extruder melt pump.
When installing an extruder melt pump, it needs to be placed on a flat ground to ensure the levelness and stability of the pump body. At the same time, the inlet and outlet pipes need to be connected well and ensure that they are well sealed to prevent leakage and pressure loss. During commissioning, it is necessary to check whether the rotation of the pump is flexible, whether there is any stagnation, and ensure that the bearings and seals are well lubricated. Then, the pressure and temperature parameters of the pump are adjusted according to the actual needs to meet the requirements of the production process.
3. Operation and maintenance of extruder melt pump.
When using an extruder melt pump, it is necessary to open the valve of the inlet and outlet pipes to ensure that the molten plastic or rubber material can enter the pump chamber smoothly. At the same time, it is necessary to observe the operation of the pump, and if abnormal sound or vibration is found, it should be stopped in time to check and troubleshoot. In the daily use of the pump, it is necessary to regularly check the wear of seals and bearings, replace the wear parts in time, and keep the pump body clean and well-lubricated. At the same time, it is also necessary to regularly clean the pump chamber and inlet and outlet pipes to prevent clogging and bonding.
