concrete pump output is calculated

Concrete pump actual average output, according to the maximum output of concrete pumps, piping conditions and Wheel Loader efficiency, calculated as follows:
Q1 = 0max * a * η
Where Q1-one for each concrete pump actual average output volume (m / h);
Qmax-each concrete pump's maximum output capacity (m / h);
a - piping condition factor. Desirability of 0.8 to 0.9;
η-operating efficiency. According to the concrete block machine concrete pump intermittent feeding time, dismantling concrete output tube and fabric stop, etc., preferably 0.5 to 0.7.
