High temperature melt pump is a high viscosity polymer melt conveying, pressure and melt metering equipment essential. High temperature melt pump than other types of pump structure is compact, reliable operation, low energy consumption, high volumetric efficiency, the shearing of the melt flow in small, stable high viscosity at high pressure, no pressure fluctuation.

　　1 be careful will pump to open the packaging carefully check, if damaged or missing parts, please contact me. This pump is a high temperature alloy steel material manufacture, all parts are heat-treated higher hardness, and thus a more brittle material is precision equipment. Any impact and collision may cause serious damage, with ring installation recommendations

　　2 please install accurately judge the pump entrance and exit. Install the right pump shaft clockwise rotation direction. Install motor, reducer, a universal coupling and pump, pump must be installed base is fixed, ensure the pump seat and the motor drive shaft concentricity, rotation must have no card, otherwise it will cause a gear stuck, serious when the drive shaft fracture

　　3 pump body appearance are a pressure sensor and a temperature sensor hole by hole, install the sensor correctly, otherwise the measurement data deviation. The pump body is connected with high strength bolts to ensure the safe operation of the pump body

　　4 just start the pump, should run at low speed. Pump operation is stable, can be gradually adjusted to normal speed and pressure. If the pump rotation is not smooth, must stop the pump inspection, so as not to pump damage. As with packing seal, often adjust the sealing cover position, so that the sealing state in the best

　　Removing and cleaning three, melt pump

　　1 be careful of the pump is removed from the device, a vacuum heating furnace in the slow heating for two hours, the temperature should not be overheating or easily leads to a decrease in hardness material of pump body, pump body size stabilization effect

　　2 during the heating process, the residual material melt discharge. Turn rotary bolt sealing gland, front cover. All parts sold to keep direction, when installing all the homing. Remove the gear for solid material adhesion to have residual, do not use a hard object struck and damaged gear and bearing of the corner, but should use plastic or soft copper hammer gently tap to remove it

　　After the collapse of 3 pump should be gently on a clean surface to remove the gear and a sealing component, first clean the parts by compressed air or a clean cloth. And carefully check all parts have no wear, cracks, burrs and scratches. Use sand paper burnish gently attached on the surface of the object, or to be especially careful measurement of gear, the middle plate and the bearing, do not go to the metal or grinding on the. It will affect the measurement of its functions

　　4 parts after grinding, with three ethyl chloride or vinyl chloride solvent cleaning, and then wipe clean cotton cloth, do not use paper towels, because there may be paper or impurity clung parts, cleaning before installation

　　Four, melt pump assembly

　　1 before the assembly for a pot of oil, pump body, cover, and the driving and driven gears, the sealing component and a sealing gland assembly shall be lubricated. Please strictly in accordance with the parts assembly disassembly sequence reverse each installation, all components of the correct position

　　2 mounting bolts, please use the high temperature grease screw, bolt tightening diagonal sequentially and cover. Always keep the free rotation state. If there is any card dead phenomenon, can not be forced assembly or rotating pump, such as correct, all parts should be easily loaded into, the pump shaft will be very relaxed.
