2019-08-22 Suggestions on Daily Use of Special Melt Pumps

Some methods and suggestions are adopted in the daily use of single screw special melt pump. 1. Desulfurization of the conveying medium (when the conveying medium contains corrosive medium) or adding corrosive inhibitors. 2. Installation and operation of melt pump shaft of single screw special melt pump should be strictly carried out in accordance with the regulations, so as to avoid eccentricity of shaft and defects of shaft body and eliminate stress concentration. 3. It is suggested that the material with good toughness (e.g. high temperature tool steel, tungsten carbide, etc.) should be sel

2019-07-04 Energy Efficiency Characteristic Analysis of Melt Gear Pump

Years of experience in gear pump development and production, Zhengzhou Bate gear pump manufacturers provide special gear pump equipment including: chemical gear pump, bottom gear pump, gear metering pump and so on. The comprehensive analysis and interpretation of the energy efficiency characteristics of the melt gear pump are as follows: 1. The relationship between energy efficiency of melt gear pump and melt temperature rise. The energy efficiency of the melt gear pump is low. In fact, the non-zero clearance layer of gear pump changes from mechanical energy to thermal energy due to viscous he

2019-05-21 Importance of Controlling Speed of PET Melt Gear Pump

In continuous PET production, it is very important to keep the rotational speed of gear pump stable for the material balance and stability of the whole production. The rotational speed of the melt gear pump can flexibly choose whether to adopt flow control or pressure control according to the control emphasis. Flow control has the advantages of direct control and intuitive flow display, while its disadvantages are that the pressure before pump is not easy to be stabilized due to the increase of granulation and spinning. The advantage of pressure control is that pressure regulation is timely an

2019-05-13 Details needing attention during installation of melt pump for extrusion

Zhengzhou batte is a professional manufacturer of high-temperature gear pump in China. It provides high-performance and high-standard melt gear pump equipment. This paper introduces the matters needing attention in the installation process of melt pump for extrusion . 1. melt pump for extrusion is installed in cold state and operates at high temperature. Therefore, the influence of thermal expansion and contraction of pipeline and pump body must be taken into account to avoid imposing additional moment on pump shaft and affecting the normal operation of pump. Therefore, when installing in cold

2019-04-24 Characteristics of Melt Metering Pump on Production Line

Melt metering pump is a kind of tool used in extrusion production line. It has the advantages of stability and high efficiency, so it is widely used in many fields. So what are the characteristics of the melt metering pump that can be favored by everyone? Firstly, the components of the melt pump are very simple, mainly consisting of three parts: power drive, fluid transmission and regulation control. In the process of operation, the transmission of medium is realized by clicking the drive gear. Then, in the process of conveying, by adjusting the speed of the motor, the flow rate of the melt me

2019-03-28 Safety Protection Measures of Melt Booster Pump

1. Improving the Reliability of Melt Pressure Detection by Redundancy Method Because of the high power of the melt booster pump, the high temperature and pressure of the transported polyester melt, the measurement of the outlet pressure of the melt booster pump is required to be reliable and accurate, and safety accidents due to the failure of the pressure gauge are not allowed. Using the redundancy method, two pressure transmitters are installed at the outlet of the melt booster pump to measure the pressure (as shown in Figure 3). Then a higher pressure transmitter is selected by the selectio
