The reasons for sand and gravel pump clogging are as follows:
When the particle size of the sand and gravel exceeds the passing capacity of the sand and gravel pump, the larger particles can not pass through the pump body smoothly, and are likely to accumulate in the pump inlet, impeller or pipeline, resulting in clogging.
If the solid particles content in the conveyed medium is too high, exceeding the handling capacity of the gravel pump, too many solid particles will gather in the pump, forming a blockage.
Excessive bending of the suction line, the presence of foreign objects or clogging by sediments, etc., will affect the normal suction of the pump, so that the sand and gravel are blocked in the suction process, resulting in clogging.
If the rotational speed is too high, it may make the sand and gravel in the pump residence time is too short, too late to discharge, thus accumulating clogging; while the rotational speed is too low may lead to the sand and gravel transport is not smooth, also easy to clog.
In the conveying process, the medium may occur precipitation or solidification phenomenon, especially in the pump stops working for a period of time and then start, the precipitate or solidification is easy to clog the pump body.
Such as suddenly stopping the pump operation, not following the correct operating procedures, etc., may lead to the accumulation of sand and gravel in the pump, forming a blockage.
