Improvement of mechanical seal for polyester high temperature melt pump

The polyester high temperature melt pump provided by Zhengzhou Bart has the advantages of compact structure, reliable operation, low energy consumption and high volumetric efficiency. The high temperature melt pump has little shearing effect on melt, the most stable flow at high viscosity and high pressure, and no pressure fluctuation at the outlet. It plays an irreplaceable role in polyvinegar production. The pump shaft seal adopts double end bellows mechanical seal. The shortcomings of polyest

High temperature 0.4CC type plastic extrusion melt pump

Melt pump is mainly used for high temperature and high viscosity polymer melt conveying, supercharging and metering. Its main function is to pressurize and stabilize the high-temperature melt from the extruder to keep the melt flow accurate and stable into the extruder head. Nowadays, melt gear pump has been widely used in chemical fiber, granulation, plastic film, sheet, sheet, profiles, pipes, wires and cables, wire drawing, composite extrusion and other production lines. Processing materials

Safe use of polyester melt gear pump

1. The temperature of the heat medium jacket of the pump body can be slightly lower than the heat medium temperature of the front and rear clamping sleeves. Because the viscosity of the melt decreases with the shear rate, the extrusion of the gear and the shear of the bearing will raise the melt temperature by 3-5 degrees Celsius after the pump. Reducing the temperature of the heat medium can prevent the melt from degrading. The data show that the bearing capacity can be greatly increased by red

Influence of melt pump operating pressure on sealing performance

Driving shaft seal is to prevent a large number of melt leakage, for the inlet of a negative pressure melt pump , driving shaft seal also plays a role in preventing outside air into the pump cavity. There are many forms of shaft seal of melt pump. Lantai melt pump drive shaft seal device is mainly composed of shaft sleeve, lubrication spacer ring, sealing filler, labyrinth seal ring. The pressure regulating valve plays a key role in the packing sealing melt pump. When the pressure of the melt pu

Cause of leakage of seal and end cover of melt booster gear pump

According to the serious analysis of the causes of the faults and the damage of the spare parts under the on-site maintenance and replacement, Zhengzhou Bart can think of the following reasons: (1) Because of the high assembly accuracy of the melt supercharged gear pump , the clearance between the gear shaft and the sliding bearing is 0.2 mm, while the sliding bearing and the gear shaft rely on the melt material self-lubrication, sliding. The main reason for the sticking resistance is that the w
