The special melt pump for PVB extruder solves two problems

Melt pump is mainly used for conveying, pressurizing and metering of high temperature and high viscosity polymer melt. Its main function is to pressurize and stabilize the high-temperature melt from the extruder, and keep the melt flow accurate and stable into the extruder head. Direct regulator control can be achieved to eliminate the impact of extruder fluctuations and screw on the die. The extruder is effective in extruding the melt and mixing technology to deliver the resin material, but it is not efficient enough to provide the die with a constant pressure and volume of the melt. The hot melt pump can achieve effective pressurization of the melt and accurate metering of the melt.

In the production of PVB interlayer film, the delivery of melt is inseparable from the melt pump. The general melt pump includes a pump body, a drive shaft, a driven shaft, bearings and seals. The melt pumps currently used in PVB interlayer film extruders have two problems: one is that they are equipped with sealing rings, which have a limited life and need to be replaced frequently; the other is that the inner cavity of the pump body needs to be lubricated frequently, which is quite It is troublesome, which affects the service life and working efficiency of the entire melt pump as a whole, so it is very necessary to improve the melt pump.

Zhengzhou Batte melt pump manufacturer provides a new type of special melt pump for PVB extruder that does not require sealing rings and lubrication, which solves the above two problems very well. The structure and advantages of the special melt pump for PVB extruder are described as follows. The special melt pump for PVB extruder is provided with a drive shaft and a driven shaft installed on the side wall of the pump body in parallel in the pump body. A liquid inlet cavity and a liquid outlet cavity are formed between the two booster gears and the inner wall of the pump. The side wall of the pump body of the liquid inlet cavity is provided with a feeding port, and the side wall of the pump body of the liquid outlet chamber is provided with a feeding port. The drive shaft extends out of the pump body to be connected with the drive shaft of the power equipment, and the side walls of the pump body at the feed port and the discharge port are provided with screw holes for connection. A bearing seat and a bearing are arranged between the drive shaft and the driven shaft and the side wall of the pump body; the power equipment is a DC motor. The special melt pump for PVB extrusion has the advantages of simple structure, low cost, good sealing, high working efficiency and beautiful appearance. info@battemachinery.com
