Concrete duct blockage Troubleshooting

Concrete duct blockage Troubleshooting 1. Anti-pump exclusion Once the anti-pump operatively plugging button, the general anti-pump 2-3 strokes, then positive pump, blocked tubes can be ruled out. If this operation is repeated 3-4 times, still can not be ruled out, only to tobemac concrete vibrator hose with different standard find the blocking position, pigging excluded. Split tube should be preceded by the anti-pump, release the pressure in the duct, so as not to split pipe concrete splash wounding. 2. blocking position determination If the anti-clog pump operation can not be excluded, they have to find out the blocking position, dismantle the tube removed. While anti-pump can - being alternately operating the pump, a duct beat edge. Clogging places, sounds boring, and there is no concrete flowing Cha Cha sound. Find out the location, apart cleanup. Usually straight tube blockage less likely, the possibility of large bend, easy to plug the end of the tube. If the anti-pump can not operate powergen 6m hose diesel engine power concrete vibrator normally, a stroke are gone dissatisfied, it may be concrete cylinder or s tube blockage, should immediately release the hopper feed, water and clean concrete tank. 3. The blockage causes and preventive measures Due to poor quality of concrete or duct layout is unreasonable, will cause congestion, but they can be controlled by the operator is avoided. Mixing System Troubleshooting 1. Concrete pumping feed poor performance, large stirring resistance, pump mixing blade stuck. Stuck should be reversed. 2. stirred relief valve set pressure enough. Stirring with a wooden stick blade jammed, the pressure at 12.5Mpa. 3. The hydraulic motor is damaged. Check and, if necessary, replaced. 4. Mixing system gear pump damage. Check and replace. 5. The manual valve professional manufacture korea type concrete vibrators operating lever pull off or failure, so move the valve spool is not in place. Check and replace. 6. The stirring shaft or sleeve damage. Need to clean up and maintenance.
