It is particularly evident that the delivery capacity, the outlet pressure, the motor power and the form of distribution valve are the main factors that affect users to select and purchase concrete mixer pump, but the output capacity is also a big factor in selecting and purchasing the concrete pump with mixer. Generally, users will calculate the output capacity to meet their needs before purchasing a electric or diesel concrete mixer with pump. However, Do you know how to calculate the output capacity of concrete pump? I will explain it to everyone this hour and moment. The output capacity of concrete pump mainly includes calculation on output of concrete pump and calculation on the quantity of required concrete mixing trucks for each cement mixer pump.

**Calculation on Output of Concrete Mixer Pump**

The actual average output of concrete pump can be calculated on the basis of the maximum output of concrete pumps, piping situation and operating efficiency, and the calculation formula is: Q1 = 0max * a * η

In the formula, Q1 is the actual and average output of each concrete pump, and its unit is m/h.

In the formula, Qmax is the maximum output of each concrete mixer pump, and its unit is m/h.

In the formula, a is the piping condition factor and the value of a may be 0.8 to 0.9.

In the formula, η is the working efficiency and the value of η may be 0.5 to 0.7. The work efficiency is calculated in accordance with the break time of concrete pump, the situation of concrete delivery pipe and so on.

**Calculation on the Quantity of Required Concrete Mixing Trucks for Each Concrete Mixer Pump**

When the concrete pump is continuously operated, and the quantity of required concrete mixing trucks for each concrete pump can be calculated according to the following formula: N = (Q1/V) * (L/S + Tt)

In the formula, N is the quantity of concrete mixing truck, and its unit is Tai.

In the formula, Q1 is the actual and average output of each concrete pump sale, and its unit is m/h.

In the formula, V is the capacity of each concrete mixing truck, and its unit is m.

In the formula, S is the average speed of concrete mixing truck, and its unit is km/h.

In the formula, L is the round-trip distance of concrete mixing truck, and its unit is km.

In the formula, Tt is the total suspension time of each concrete mixing truck,and its unit is h.
