How to determine the concrete pump truck blocking the site
Pumping action and hydraulic system are normal, no abnormal sound and vibration, the hopper has a larger aggregate or agglomeration, at the feed port stuck or arch and blocked.
When the delivery pressure gradually increased, and the hopper material does not decline, the pipeline outlet is not expected, the pump vibration, piping is also accompanied by a strong vibration and displacement, can be judged to be blocked.
S pipe valve is blocked gradually formed, the main reason is that after pumping the finished product concrete, there is no timely use of high pressure water rinse, resulting in commercial concrete residue in the S tube, the course of time gradually thickening, accumulation consolidation, causing clogging.
Pumping system action suddenly interrupted, and there are abnormal sound, the device has a strong vibration, but no corresponding vibration within the pipeline.
