  small mobile concrete batching plant in operator in the construct ion of pumping energy should be focused, pay attention to the time the pump delivery pressure gauge readings, once found pressure gauge readings suddenly increased, should be immediately 2-3 against the pump stroke, then is the continuous concrete mixing plant , blocking the tube can be ruled out. If it has an anti pump, is the pump several operating cycle, has not ruled out plugging, should promptly remove pipe cleaning, otherwise it will make more serious plugging.

  The pumping speed of improper selection

  Pumping concrete mixing  station , the rate of choice is the key, the operator can not blindly map quickly, sometimes More haste, less speed. The first pump, because the pipeline resistance is large, you should slow pumping, pumping normal, may be appropriate to improve pumping speed. When plugging a sign or a car slump of concrete is small, should slow pumping, the plugging nipped in the bud.

  Inadequate control over feeding amount

  Pumping concrete batching plant for sale , the operator must be ready to observe more than expected in the hopper, the remainder shall not be lower than the stirring shaft, if the material is too small, easily inhaled air, resulting in plugging. Hopper in the feed can not heap too much, should be lower than the fence in order to facilitate the cleaning of coarse aggregate and large aggregate in a timely manner. When a car concrete slump is small, the remaining material can be lower than the stirring shaft and control in "s" tube or intake above, to reduce the stirring resistance, swing resistance and inhalation resistance. This method only applies to "S" series of concrete pump valve.
