Descripción del producto

Principle of vacuum transferring:
Vacuum is generated by a compressed air-driven vacuum pump (A). The pump can easily be automatically controlled. Since it has few moving parts, the pump is virtually maintenance-free.
As the vacuum pump start up, the vacuum is raised in the container (B) and the conveying pipeline (C). From the feed station (D) the material is drawn into the conveying pipeline and then on to the container.
The filter (E) prevents dust and fine particles from being drawn into the pump and escaping into the surroundings.
During the suction period, the air shock tanks (F) are filled with compressed nitrogen. Conveying for a specified time, the compressed nitrogen in one of the filter tank is released and cleans the matching filter.
According to the time defined in control system, all air shock tanks will burst one by one. The filters will be clean one by one in the cycle period. The suction and clean times are normally controlled by pneumatic or electrical control systems (G).

Theoretical calculation for vacuum transferring

The material flow is determined by the diameter of the conveying pipeline, the vacuum flow, conveying distance and not least by the characteristics of the material.
The relationship between material flow and vacuum flow is usually stated as phase densities and is a dimensionless quantity. If the phase density is the same as the bulk density, it means that there is no air in the conveying pipeline and that the pipeline is blocked. The converse also applies. If the phase density is equal to zero, there is no material in the conveying pipeline. Between these two limits, a range of phase densities may occur.
Dense phase means that the material is conveyed in separate plugs in the conveying pipeline. For most materials, the phase density is a factor above ten for dense phase. Some materials can be conveyed in dense phase.
Another conveying phase is dilute phase. The phase density is usually below ten. Conveying speed in dilute phase is usually >*0 m/s.

The figure below shows conveying phases with different phase densities. From very dilute phase (1), over dense phase (6) to blocked pipeline (7).
It is generally the case that in dense phase, because the material moves in the form of plugs, the vacuum level is usually ***5%, while in dilute phase it is ***0%.
