2021-08-30 Selection requirements for melt metering gear pumps
The melt metering gear pump provided by Zhengzhou Batte is widely used in the production lines of chemical fiber, film, sheet, composite extrusion, pelletizing, etc., covering almost all polymer materials, such as PC, PMMA, ABS, PET, PVB, HIPS, Fluoropolymer, thermoplastic elastomer, rubber, etc. The selection of melt metering gear pumps needs to be based on the requirements of different occasions, and the following conditions need to be fully considered. 1. The flow rate of the liquid to be measured, and the requirements for measurement accuracy. 2. The main characteristics of the liquid bein
2021-08-28 What are the characteristics of the miniature precision melt gear pump?
The pump head of the miniature precision melt gear pump has a variety of materials to choose from, which is suitable for the metering, conveying and sampling of various acids, alkalis, solvents, and various chemical additives. The flow control of the pump can be realized by using controllers such as AC, brushless DC motors, air motors, etc. It can be applied to high pressure difference, high system pressure and wide medium viscosity range. The high precision of the miniature precision melt gear pump ensures the accuracy and repeatability of the flow rate. It is especially suitable for pulsatio
2021-08-27 Zhengzhou Batte manufacturer interprets the improvement plan of axial compensation melt gear pump
Fault phenomenon: The common faults of the melt gear pump are the weak lifting of the boom, jamming, no oil absorption, or extremely low volumetric efficiency; it is found that the side plate of the pump is warped, and the sintered copper layer is worn and peeled. , The gear is scorched and blackened, the bearing sleeve is broken, the needle rollers fall apart, and the 3-shaped sealing ring is broken. Failure analysis: Zhengzhou Batte conducted a lot of analysis and improvement work on this failure, including improving the flatness of the gear end face, improving the forming process of the sid
2021-08-26 What are the reasons why the melt pump cannot be started?
In the daily use process, the melt pump may not start normally; Zhengzhou Batte melt pump, based on years of experience, gave the following 8 kinds of reasons that caused the melt pump to fail to start normally, and also gave targeted solutions. 1. Has the current melt pump body temperature reached the minimum temperature limit set? Set a new temperature limit value lower than the current temperature or wait for the temperature to rise before trying to start. 2. The current displayed outlet pressure exceeds the set value of the set pressure alarm, and the alarm pressure value of the melt pump
2021-06-07 Detailed explanation of melt pump pressure and flow
Introduction to melt pump pressure: The inlet working pressure of the melt pump does not need to be too high, generally 3-5CP. When the inlet is working, the viscosity of the liquid is higher and the working pressure is higher. Sometimes in order to better improve the mixing effect of the wear-resistant materials in the extruder screw, the top of the extruder screw head must have a high working pressure to increase the flow back. At this time, you can increase the inlet of the melt pump of the extruder . pressure. The inlet working pressure is high, and the equipment (such as extruder) can be

Introduction of PLA resin bottom melt pump The PLA resin bottom melt pump is used in conjunction with the reactor to transport and meter PLA (polylactic acid) melt; the PLA bottom pump adopts a large suction inlet flange design, which can complete the polymer material under vacuum reaction conditions delivery. PLA resin is also called polylactic acid. It is a polyester polymer obtained by polymerization of lactic acid as the main raw material. It is a new type of biodegradable material. Character
2020-04-17 Advantages of installing melt metering pump in rubber and plastic extrusion equipment
The model of melt metering pump provided by Zhengzhou Batte ranges from 0.5cc to 12000cc. The so-called 0.5cc means that the constant displacement of melt metering pump is 0.5cc per revolution. What advantages can you not ignore when the commonly used rubber and plastic extrusion equipment (extruder, film blowing machine, calender, etc.) is equipped with melt metering pump ? The specific advantages are: it can accurately control the melt flow; it can reduce the impact of the melt pressure fluctuation on the die products; it can evenly transport the molten melt to the die; it can effectively im
2020-04-15 What are the advantages of melt pump for melt blown fabric
Due to the impact of the new coronavirus pneumonia, the supply of masks is in short supply, and as the core material of masks, the melt blown fabric can not meet the needs of todays mask manufacturers. Nowadays, there are thousands of enterprises engaged in mask production in the market, which greatly stimulates the production and demand of melt blown cloth. The melt pump provided by Zhengzhou Batte melt pump factory is mainly used in the melt blown cloth production line, which is an indispensable equipment for the production of melt blown cloth. The advantages of the melt pump for melt blown
2020-03-25 melt gear pump for melt blown fabric
The polymer masterbatch is put into the extruder and melted in the extruder at a temperature of about 240 ℃ (for the main resin used in PP melt blown method). The melt flows through the metering pump to the melt blown die head. The metering pump measures the melt flow output to the nozzle. The spinneret is a capillary tube with a spacing of less than 1mm and a diameter of 0.2-0.4mm. On both sides of the capillary is the air inlet, adding 250-300 ℃ compressed air. When the newly formed polymer
