2018-07-17 Silicone rubber compound gear pump
n the filtration of silicone rubber compound, the advantage of using a gear pump is significantly larger than that of other rubber compounds, such as EPDM. This is because silicone rubber compounds have very low viscosity, so the pressure increase has a greater impact on the output of the single screw extruder. For example, the test results show that for a specific organosilicon compound, if the pressure is increased from 10 bar to 40 bar, the output of single cycle single screw will be reduced by 50%. Due to the low viscosity of silicone rubber, even under relatively low pressure growth, ther
2018-06-27 The working temperature of the melt pump
All the gears and mating surfaces of the melt pump produced by our company are finely grinded, and the clearance of assembly is strictly controlled to achieve accurate flow. The gear and the pump body use the chromium nickel alloy steel and the high temperature tool steel material according to the ZB-B series of different working conditions; the ZB-H series adopts the imported CPM tool steel or the titanium tantalum alloy material, which is quenched as a whole, the hardness is HRC62-68, and the wear resistance is good. 1. ZB-B series melt pump : working temperature: less than 400 C (750), clea
2018-06-15 How to adjust the sealing system of the melt pump
The new melt pump is 24 h before driving for the first time, and the clearance of the packing gland is generally 9 mm (the factory has been set at the factory); the filler is added to the silicone oil bubble and the silicone oil leakage to the pump is normal. Before the preparation of the grain, the pressure control screw is used to guarantee the full discharge of the waste waste and the speed of the pressure control screw melt pump is controlled at 25 r/min. The pressure control screw rotates inward, pressure to show 0.3-0.5 MPa. When the melt pump reaches the normal production speed, seal ca
2018-06-07 Assembly of melt pump
1. before the assembly of the melt pump , a tank of lubricant, pump body, front and back cover plate, active and driven gear, sealing components and sealing gland should be assembled before lubrication. When assembling, please install the parts one by one in strict accordance with the disassembly sequence of each component, so that all parts are correctly reset. 2. before installing the bolts, melt the threaded parts with high temperature grease and tighten the bolts of the front and rear covers in diagonal way. Always remain free to rotate. If there is any stuck phenomenon, the melt pump must

2018-05-21 Effect of rubber extrusion melt pump on rubber extrusion line
With the continuous and stable development of rubber industry, the demand for rubber products is increasing. In particular, in recent years, family cars have been flying into the common peoples house, which has led to the great development of EPDM ethylene propylene rubber, NBR, SBR rubber materials and products, including sealing strips, resin modification, wires, cables, tubes and plastic runways, etc. Because of the particularity of rubber processing technology, the melt pump specially used for rubber is of great significance in the production line. The temperature control principle of gear
2018-05-02 Method of improving the service life of high temperature pump
1, because of the high temperature melt pump body running at high temperature, so the cold installation of piping should be equipped with hinge support, to prevent pipe displacement after heating. 2, the coupling must be heated up after the pump body is heated, so as to avoid additional torque when running. 3. When the high temperature melt pump starts, no pressure can be speeded up when the outlet pressure is not formed, so as to prevent premature damage of the shaft or bearing. 4. The temperature of the heat medium jacket of the high temperature melt pump body can be slightly lower than the
