2023-09-22 Introduction to Temperature Control Technology of High Temperature Melt Pump
During the production process of high-temperature melt pumps, three important temperature parameters need to be monitored and controlled, namely melt temperature, pump head temperature, and melt pipeline temperature. high temperature melt gear pump Among them, the melt temperature refers to the melt temperature before entering the melt pump, which needs to be controlled and monitored through devices such as heaters. The pump head temperature refers to the temperature near the outlet of the melt pump, which has a direct impact on product quality and production efficiency. Therefore, it is neces
2023-09-19 Application of High Temperature Melt Gear Pump in Microporous Plastic Forming
Microcellular plastics refer to foamed plastics with a cell diameter of 0.1~10 microns and a cell density of 109~1012 cells/cm3, which have excellent comprehensive properties. The foaming process of microcellular plastics generally goes through three stages, namely the nucleation of bubbles, the growth of bubbles, and the solidification and shaping of the foam body. Among them, high pressure and pressure drop rate are required during the nucleation process of bubbles, so high-temperature melt pumps can be used as nucleation devices. high temperature melt gear pump The high-temperature melt gea
2023-09-11 Melt gear pumps for thermosensitive materials
PVC is a thermosensitive material that is sensitive to temperature changes and is prone to carbonization, decomposition, and even coking during the extrusion process. The PVC series specialized melt pump adopts a horn shaped flow channel at its inlet, and the internal flow channel and gear structure are optimized. It is equipped with melt self-lubrication, and the lubricating materials are discharged with the materials. This structure is more suitable for the material characteristics of PVC. Advantages of PVC melt pump 1. Optimized melt channel design: eliminates dead corners in the channel, r

2023-09-05 What are the standards for melt pumps?
The standard of melt pumps is an important guarantee for ensuring equipment quality and performance. Only melt pumps that meet the standard requirements can ensure the stability and reliability of production. Therefore, when selecting a melt pump, it is necessary to pay attention to whether its standards meet the requirements to ensure the safe operation of the equipment and the improvement of production efficiency. m elt pump for extrusion 1. Design standards: The design of the melt pump should comply with relevant national and industry standards to ensure the safety, reliability, and stable
2023-09-01 What are the differences between the E-series melt pump and the ZB-B extrusion melt pump?
The companys E-series melt pump is mainly used in conjunction with an extruder to pressurize medium and high viscosity polymer melts, and after pressurization, the flow rate is stable to transport the melt to the die head. ZB-E high temperature melt pump The internal structure of the E-series melt pump is basically the same as that of the ZB-B standard extrusion pump. The main difference lies in its appearance: the special cylindrical shape of the E-series melt pump is its advantage. Due to the circular shape of the pump body, it can easily be directly connected to the extruder. The space occu

2023-08-11 Melt pump for plastic sheet extrusion system
The working principle of the sheet melt pump is based on forward emptying and screw rotation. When the screw rotates, the geometric shape of the screw thread will form a series of sealing cavities, and the plastic inside the cavity will be pushed forward as the screw rotates. At the same time, the rotation of the screw can also expel air and other impurities, ensuring the quality of the molten plastic. Plastic sheet melt pumps have a wide range of applications in the plastic extrusion industry. It is mainly used for extruding products such as sheets, plates, films, etc. For example, in the pro
