Some Ways to Solve the Calculation Problem of an Excavator Productivity or Calculation Method of a Excavator Productivity
Tags: good condition used excavator hot sale used excavator available used excavator20131007Understand the formula for calculating used excavator productivity. The formula is as follows: Q = (60*q*z*n*kef) / kl, Where Q is the productivity of the excavator, q is the capacity of each rotor bucket in cubic feet, z is the number of buckets on the wheel and n is the speed of rotation of the rotor, measured in revolutions per minute. kf stands for the filling factor of a bucket while kl represents the soilloosening factor.
Gather the data. Typically, you can get the date for the capacity of each rotor bucket in cubic feet, the number of buckets on the wheel and the speed of rotation of the rotor from the operator's manual of your excavator, supplied by its manufacturer. The filling factor of the bucket and the soilloosening factor can be determined experimentally. The filling factor, ranging from 0 to 1, determines the degree of the excavator bucket's utilization. For example, whether it is halffull or threequartersfull determines the excavator bucket's utilization. To determine the soil loosening factor, which is always greater than 1, calculate by how much the density of the soil in the ground is greater than the density of the excavated soil. For example, if the soil loosens by 10 percent, the soilloosening factor is 1.1.
Use the formula from Step 1 to calculate used excavator productivity. For instance, if the capacity of each rotor bucket is 10 cubic feet, the wheel has only one bucket, the rotor rotates at a speed of 5 rotations per minute, and the filling factor and the soil loosening factor are one, the productivity of the excavator stands at: Q = (60*q*z*n*kef) / kl = (60*10*1*5*1) / 1 = 3,000 cubic feet per hour. Kef stands for the filling factor of a bucket while kl represents the soilloosening factor.
