2019-05-30 Importance of Sealing Mode Selection for Melt Pump

The common faults of the melt pump mainly occur in the sealing, so it is very important to choose the sealing method and sealing material for the melt pump . The main sealing surface of the melt pump is between the pump body and the front and rear cover, the drive gear shaft and the inlet and outlet flange. Zhengzhou Bate Melt Pump Company provides packing and mechanical seals for melt pumps. Packing seal is a commonly used form of shaft seal of melt pump , but the selection of packing, sealing performance and structure design directly affect the sealing effect of melt pump. For the essence of

2019-04-30 Advantages of gear pump in plastic extrusion

When the gear pump in plastic extrusion is used in series with a single screw or twin screw extruder, the benefit of the whole production line can be significantly increased. The main advantages of using melt pumps are: 1. Stable output pressure - can effectively reduce the material output instability and pressure fluctuation caused by extruder parameters. 2. Improving product quality - minimizing dimension tolerance of extruded products and reducing waste and waste rate. Ordinary extruders can also produce high-precision products. 3. Increase the extrusion output-reduce the pressure requireme

2019-04-16 How to prolong the service life of high temperature melt pump

We buy the melt pump in order to meet the production and cleanliness standards. The quality, performance and service life of the equipment are related to the interests of users, so there should be no sloppy in these aspects. Under the condition of reliable quality and stable performance, we all hope that the service life of high temperature melt pump can be prolonged indefinitely, because this will benefit more. In reality, high temperature melt pump may have a series of faults, although not all, but even a little faults will lead to production decline and maintenance costs, so we should alway

2019-04-04 Characteristics of gear pump in plastic extrusion

Melt metering pump is a kind of tool used in plastic 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

2018-03-12 Polymer melt pump applications and performance advantages

The application of polymer melt pumps in the extrusion processing industry has involved the fields of granulation, extruded sheets (sheets, films), extruded tubes, blown films, profile extrusion, continuous blow molding, etc. The processed materials are almost all thermoplastic resins involved. , thermoplastic elastomers and other polymers. In addition, the output of the melt pump has a linear relationship with the rotation speed of the gear, and the melt displacement can be accurately controlled by controlling the rotation speed of the melt pump , so the melt pump can also be used as a meteri
