2023-02-22 Gear pumps for polymer applications
Polymer melt pumps , when used in conjunction with screw extruders, can improve extrusion output and quality, reduce energy consumption, and play a role in precision extrusion molding that cannot be replaced by other processing methods. At present, it can process materials covering most polymer materials, such as PE, PC, PP, PVC, PET, polysulfone, polyester, fluoropolymers, thermoplastic elastomers and rubber, etc. It has become a hot spot for the development of modern plastic molding and processing technology and equipment. 1, can achieve stable extrusion, improve the accuracy of the extrudat
2023-02-02 melt gear pump for twin screw extruder
The combination of co-rotating twin-screw and high-temperature melt pump technology realizes a new one-step process of polymer compounding and direct extrusion, which can significantly reduce costs, save energy and reduce the performance of polymer materials due to repeated heating. Typical applications are PE, PP biodegradable sheet molding and extrusion, direct blending and blow molding of PE functional films, etc. The main function of the melt pump is to pressurize and stabilize the high temperature plastic melt from the extruder and then send the flow rate to the extruder head in a stable
2022-11-29 Batte Pipe Extrusion Line Screen Changer Options
The addition of screen changers for extruded plastic products serves the following purposes. (1) Filter out impurities in the raw material, improve the quality of the product, and at the same time reduce the loss caused by the screen change. It saves energy and reduces consumption, and at the same time increases production and reduces labor intensity. (2) The addition of screen changer increases the back pressure of the machine head, greatly improving the plasticizing and homogenizing effect of raw materials, the product texture is more uniform, better finish, and the pressure resistance value
2022-11-12 Screw assembly and fixation of melt pump production process
Today, we will analyze the screw assembly and fixation, an indispensable part of the production process of the melt pump. From the perspective of environment, what kind of environment is the melt pump exposed to all day? Working in a corrosive or highly corrosive environment, the materials of the parts we use must also withstand the corrosion of high corrosivity. Because they are more or less polluted by corrosive objects, in order to ensure the operation safety of the equipment itself, we will specially order some high corrosion resistant screws on the screws used when connecting the melt pum
2022-11-05 Spare parts for melt pump

It can guarantee the spot supply and assembly supply in a very short time. Melt gear pump gear Screw seal for melt pump Cold water ring for melt pump Drive system for melt pump (motor+reducer) Universal coupling for melt pump Pressure sensor for melt pump Bearing for melt pump Cast copper heating plate for melt pump Junction box Thermocouple for melt pump Electric heating rod of
2022-10-19 Performance of melt pump for casting film production
What are the performance advantages of the special melt pump for cast film provided by Zhengzhou Batte when it is applied to the cast film production line? China melt pump manufacturer specifically analyzes the basic performance requirements of melt pump for casting film production. The performance advantages of the special melt pump for casting film are as follows: stably conveying the melt, eliminating the fluctuation of the material flow of the extruder, and ensuring the uniform thickness of the product; It can bear part of the pressure of the screen changer and die, and improve the output
2022-08-27 Operating efficiency of melt pump and D-type bearing
There is a small amount of melt loss in the melt pump, which makes the operating efficiency of the pump unable to reach 100%, because these melts are used to lubricate both sides of the bearing and gear, and the pump body is never fit without clearance, so the melt cannot be discharged from the outlet 100%, so a small amount of melt loss is inevitable. However, the melt pump can still operate well, and for most extruded melts, the efficiency can still reach 93% - 98%. The rotation speed of a melt pump is actually limited, which mainly depends on the conveyed melt. If oil is conveyed, the pump
2022-07-25 What are the guarantee measures for the stable operation of high temperature melt gear pump?
The service life of high temperature melt gear pump depends on whether a stable bearing lubrication film can always be maintained between the sliding bearing and the gear journal. The outlet pressure of the pump, the speed of the pump, and the viscosity of the melt all directly affect the bearing capacity of lubrication. In order to improve the stability and reliability of high-temperature melt gear pump operation, the following matters should be paid attention to in the operation and maintenance of melt gear pump: 1. During shutdown, it is forbidden to keep the high-temperature melt gear pump

2022-06-09 What is the relationship between melt pump displacement and gears?
For high temperature melt gear pumps, there are three standard gear types as well as some special gear types with smaller or wider gear pumps or adjusted geometries. High temperature polymer melt gear pumps are available in spur, helical and herringbone gears. Each of these gear types has different properties that are important to the use of the gear type. What is the relationship between melt pump displacement and gears? The volume of melt discharged by the melt pump per revolution is called the theoretical displacement of the pump, or the displacement of the pump, and the unit is cc/r. For a
