Edit: Zhengzhou Melt Pump Date: 2019-11-07 10:22:01

Zhengzhou Lantai, as a professional plastic melt pump manufacturer in China, has provided great improvements in the structure and performance of plastic melt pumps; Lantai's new generation of plastic melt pumps have not only achieved great energy saving and consumption reduction. The improvement and the overall service life of the plastic melt pump. The following is the focus of Zhengzhou melt pump manufacturers on the daily maintenance of plastic melt pump seals.

Melt pump

The daily maintenance of plastic melt pump seals is relatively small. The main inspection items are: leakage from the shaft end of the melt pump, the pressure of the seal cavity, the level of the sealing liquid, and the leakage of the sealing system. The liquid level check of the plastic melt pump sealing liquid is particularly important when starting and stopping, because the pressure fluctuations during the start and stop are relatively large. If there is no sealing liquid, the gas can easily leak into the system through the shaft end of the melt pump. As a result, the subsequent equipment of the melt pump, such as the broken belt failure of the pelletizer.

If leakage occurs at the shaft end of the plastic melt pump, it can be eliminated by adjusting the pressure of the seal cavity; the pressure adjustment of the seal screw cavity is a very important part of the maintenance work of the seal of the plastic melt pump. There is a pressure sensor in the screw cavity, which can measure the pressure difference between the screw cavity and the pump body. The pressure value is set at 100-300 kPa. Generally, after the pressure is adjusted in place when driving, there is no need to adjust it in daily maintenance. Zhengzhou Lantai is a professional manufacturer of melt pumps. It provides melt conveying equipment including: rubber extrusion melt pumps, corrosion-resistant polymer melt pumps, PVC sheet melt pumps, etc. For more details, you can consult the 24-hour service hotline on our website: 159 3718 9507
