common concrete pump or pump displacement calculation

Concrete pump or pump model is selected according to its pumping capacity, and its pumping capacity generally based on the maximum displacement per unit time (m3 / h) and cement mixing machine distance (m) to represent. These values ??are generally in the product technical specifications have, in the choice of concrete pump or pump type and calculate the number of units, we need to use these data. But in the product specification given in these data are in some standard conditions (such as concrete slump 18 ~ 21cm pebbles) can be achieved under continuous pumping data, Concrete block machine and maximum pumping distance is not may be achieved simultaneously. When conditions are not the same standard conditions as described above, concrete pump or pump the actual pumping capacity is bound to change. So in the actual construction of concrete pump or pump pumping capacity of less than actual technical specifications given in the data, during the construction organization design, according to the specific conditions to determine the actual concrete pump pumping capacity can be achieved.
