Translation of "Saugförderung" in English

Alternatively, it can be conveyed by a combination of pressure and suction.

Alternatively, the detached fiber material is transported away by means of a suction conveyor.

Further we construct suck special solutions for almost all uses in that production.

Concerning vacuum conveying the penetration of the material into the blower must be excluded safely.

There is a difference between pressure- and suction conveyance.

Up to now for the generation of the negative pressure required for vacuum conveying Johnson Controls used positive displacement blowers made in America.

Combined with the principle of vacuum conveying, all important requirements in terms of Containment are fulfilled.

The wear marksmen would bend can both suck used become in the pressure production as well as in that production.

The material was conveyed from big-bags to the doser of the FoodSafety-IRD via suction conveying.

This can be performed by means of a commercially available core shooter or also by suction delivery and subsequent blowing.

For a combined pressure and suction feed of the perfusion fluid the transport device 16 has a pressure pump unit 30 and a suction pump unit 31 .

In this suction transport the operating pressure of the pump is adjusted according to the desired delivery rate to overcome the obstacles to flow in the suction branch.

During vacuum operation or suction conveying, as achieved with the suction appliance 7 according to FIG. 1, the discharge flap 13 is closed by the prevailing vacuum, whereas it has to be closed against the excess pressure prevailing in the separator container if compressed air is employed during transport of the material.

The Venturi tube is preferably designed such that the pressure in the region of the zone L 2 is less than the ambient pressure (suction conveying) and/or that the flow in the region of the zone L 2 is turbulent, in which case the Reynolds number should be at least 1000, preferably at least 2000, more preferably at least 3000, most preferably at least 4000, and typically less than 10 000 000.

The conveying system comprises the material hopper, a separate blower station which creates the vacuum required for suction conveying and an interconnecting self-cleaning central filter.

Here, the PET regrind is crystallized and pre-dried, to feed the extruder in the next step by suction conveyor and gravimetric feeding.

The washed PET bottle regrind is delivered in Big-Bags and is moved to an available crystallizer via discharge station and suction conveyor.

A central vacuum generator (rotary piston compressor station) supplies the negative pressure required for vacuum conveying at the conveyor stations combined with a central filter to collect and eject dust particles carried along in the conveyor air.

The material supply with the dosing system along with the blower station and central filter for suction conveying the materials from the silo and storage tanks is positioned on a platform directly above the extruder feeder.

If the machine is placed before a suction pneumatic transport and it stops working, the product will keep flowing through it.

The new E-series remedies this situation, reduces costs and opens up new application possibilities in the field of vacuum conveying - for example in foodstuff technology, plastic granulate pneumatics and in the chemical industry.

The application of automation technologies in the field of bulk solids transport - comprising both mechanical systems (screw conveyors, bucket elevators, chain conveyors...) and also pneumatic systems (conveying under overpressure and by vacuum, fluidized bed chutes...) - has a very strong impact on production and productivity.

The method according to claim 1, wherein the comminuted material is relayed by suction conveyance after at least one comminution and/or separation stage.

Moreover, the invention proposes an unpressurized lubrication of the rolling bearing by means of the lubricating oil mist which is produced in any case during the operation of the internal combustion engine. The bearing peg projects radially beyond at least one adjoining shaft section at least within a fractional periphery, and at least one radially outwards extending rib is arranged within this fractional periphery between the shaft section and the associated bearing peg section, said rib being arranged at an angle of inclination to the axis of rotation of the balancing shaft and serving as a shovel for pressure or suction delivery of the lubricating oil mist into the rolling bearing.

The rotary piston engine according to the invention is advantageous with respect to the machine of the prior art in that it can also be used for suction conveyance and has an extremely favorable speed ratio between the external rotor motor and the power component of the rotary piston engine so that a rotational speed of 4,000 rpm leads to a relative speed of 400 rpm of the rotors for a gear ratio of 9/10.

Finally, for stiffening the balancing shaft and for promoting the above-mentioned pressure or suction delivery of the lubricating oil mist into the rolling bearing, the invention proposes to arrange in the recess, at least one web extending radially outwards and connecting the bearing peg sections to each other, this web and the rib being inclined at the same angle of inclination to the axis of rotation of the balancing shaft.

In principle, pressure delivery can work with slower delivery rates than suction delivery, since the pressure reserves under elevated pressure are greater than under reduced pressure, and since the delivery gas density which drives the product onward increases with rising pressure.

The light, non-free-flowing and comparatively long fibers 5 are sucked under the feed screw shafts 45, 46 by the air stream S or the suction conveyance so the fibers 5 can be captured by the feed screw shafts 45, 46 and be conveyed.
