What are the difficulties in the processing of small displacement melt metering pumps?
Hot melt gear pump is a kind of gear pump. Its metering principle is: when the gear of the melt metering pump rotates, a suction cavity with an increased volume is formed on one side of the feed hole, and the melt enters the suction cavity from the feed hole and fills the tooth valley. With the rotation of the gear, it is continuously brought to the side of the discharge hole, and the side of the discharge hole squeezes the melt in the tooth valley with the meshing of the gear teeth, forming an extrusion cavity to press the melt out of the pump from the discharge hole. For the extrusion melt pump with small displacement, there are the following four difficulties in the processing process.
1. The parts processing technology has high requirements. In order to ensure the high wear resistance and corrosion resistance of the melt metering pump, the parts should be subjected to vacuum heat treatment and deep ice cold treatment before processing.
2. The small-displacement melt metering pump has a small gear module, requires high precision, and is difficult to process.
3. The five gear holes of the middle plate, the main and driven holes of the inner cover plate, the partition plate and the outer cover plate are arranged in a planetary arrangement, and the position of the five holes is required to be high, the hole finish is required to be high, and the grinding is difficult.
4. The thickness of the middle plate is thin, the flatness and parallelism of the two planes are very high, the surface finish is high, and the grinding is difficult.
The small displacement pump melt gear pump for plastic extruder provided by Zhengzhou Batte are 0.1cc, 0.2cc, 0.5cc, etc., which can meet the production needs of users. For more information on melt metering pump models or equipment quotations, please send an email to info@battemachinery.com.
