First of all, to calculate the size of the shaftless screw conveyor capacity, it is necessary to understand the characteristics of the conveyed material and the conveying specifications. The characteristics of materials include density, particle size, temperature, wetting force, adhesion, etc. Conveying specifications include conveying volume, conveying distance, conveying height, setting angle, etc. According to the characteristics of the material and the conveying specifications, select the appropriate shaftless screw conveyor model and parameters.
According to the characteristics of the material and the conveying specifications, the capacity can be calculated according to the transmission theory formula of the shaftless screw conveyor. The formula for calculating the capacity of a shaftless screw conveyor is:Q=FspΩp/3600
Among them, Q represents the conveying capacity, the unit is m³/h; Fsp represents the force of the material on the screw blade, the unit is N; Ωp represents the screw speed, the unit is r/min.
The calculation formula of Fsp is:Fsp=γQH/(πD^2)
Among them, γ represents the density of the material in kg/m³; Q represents the conveying capacity in m³/h; H represents the conveying height in m; D represents the screw diameter in m.
The calculation formula of Ωp is:Ωp=60n/(πD)
Among them, n represents the motor speed, the unit is r/min.
When calculating the capacity of the shaftless screw conveyor, it is also necessary to consider the actual situation and usage requirements. For example, the temperature and viscosity of the conveyed material will affect the conveying volume; the farther the conveying distance, the smaller the conveying volume; the larger the screw pitch, the greater the conveying volume. Therefore, in the process of capacity calculation, it needs to be adjusted according to the actual situation to meet the usage requirements.
To sum up, the calculation of the capacity of the shaftless screw conveyor needs to select the appropriate equipment model and parameters according to the characteristics of the material and the conveying specifications, and then calculate according to the theoretical formula of the transmission, and adjust it according to the actual situation and the use requirements.
