Particle separating diameter of hydrocyclone in drip irrigation system

The design principle of the hydrocyclone in the drip irrigation system is discussed. On this basis, the main structure parameters of the hydrocyclone is obtained. Based on the right comprehension of the equilibrium orbit theory significance, a particle separating diameter formula is deduced by the single particle fluid dynamics model; then the particle separating and classification diameter of the hydrocyclone are calculated. The results show that this hydrocyclone can filtrate the sand particle efficiently in the water supply source and ensure the drip emitters of the drip irrigation system not clogged.
