Five troubleshooting methods for high viscosity internal gear pumps
1. The high viscosity internal gear pump does not absorb or drain. Most of the failures are caused by the bottom valve being stuck, the drainage part being fouled, the water absorption height being too high, or the suction pipe leaking. The inspection should be carried out one by one, and the bottom valve should be repaired, the fouling should be removed, and the steering should be corrected.
2. The high-viscosity internal gear pump pipe leaks or leaks. Mostly because the nut is not tightened. If the leakage is not serious, the residual oil pump can apply cement slurry, wet mud or soft soap to the leak; if the joint leaks, use a wrench to tighten the nut. In case of serious water leakage or air leakage, it must be disassembled.
3. The high-viscosity internal gear pump asphalt pump vibrates violently. It may be that the electric rotor is unbalanced or the coupling is poorly coupled. Sometimes the bearing wears and bends, the parts of the rotating part are loose and broken, and the pipe bracket is not strong, which may cause vibration. It should be adjusted, reinforced, inspected or replaced separately.
4. The high-viscosity internal gear pump impeller is broken. When the damage is not great, it can be repaired. If the damage is serious, it should be replaced or plated with cemented carbide. If it is completely damaged, the impeller should be removed and sent to the repair shop for repair.
5. The high-viscosity internal gear pump shaft is bent. Mostly due to the impact load, the heat transfer oil pump belt is too tight, improper installation and so on. If the bend is not serious, use a manual screw to correct it, but do not use too much force to prevent complete breakage.
