About Vacuum Producers

Vacuum Producers About Vacuum Producers The heart of the system The vacuum producer is the heart of the system. Here the negative pressure is created that drives the system. In Dustcontrol extraction systems, the vacuum level is gene rally from 6 kpa. Our normal source extraction and vacuum cleaning systems use turbopumps. This device has an ideally suited characteristic capacity for this type of system. Vacuum level increases as more resistance is pre sented, an important quality in minimizing the possibility of blockages in the tubing system. For applications involving fume and light dust, such as paper, radial blowers are used. These have larger air-flows and operate at a lower, relatively constant, vacuum level. Our turbopumps and radial blowers have very high quality silencing, see technical speci fications. Turbopumps Dustcontrol s turbopumps are regener ative blowers, both the direct and belt driven models. As the impeller rotates, centrifugal force moves the air from the root of the blade to the tip. Leaving the tip, air flows around the contour of the housing and is picked up at the root of the succeeding blade. The closed area of the housing between the outlet and inlet, forces the air to atmosphere. The many blades on the impeller create increasing stages of pressure generation and result in a very stable pressure differential capability. This pressure generation causes heat to be generated naturally which dissipates in the air flow and through the blower housing. Silencing, particularly on the larger units is very effective.when two or more units are installed in parallel, they can be operated on demand for maximum efficiency and minimum energy consumption. Radial Blowers Dustcontrol fans are radial blowers, air is introduced at the center of the fan wheel and forced outward with centrifugal force toward the fan housing. These fans can be operated fully restricted in a free-wheel ing condition without adverse effect and can therefore be operated without vacuum relief valves. The fans are designed for pressure and are overloading type units. They cannot be operated without being connected to the restriction of a tubing system. Operation above their maximum rated flow will result in overloading and the motor protection will trip out. To limit the power surge at start-up, install a shutter valve on the inlet which should be closed when the fan starts. 7

Outlet pressure losses from a normal outlet (silencer, back-flow valve/bend) have been accounted for in the curve. Additional equipment such as a diffuser can result in increased pressure loss and must be taken into consideration. Stated air-flows are for standard air (1.3 kpa@ C). The stated curves are for negative application, all pressures stated are assumed to be below relative atmospheric pressure at sea level. These devices can also be used for positive pressure application and will generate a greater pressure differential.

Vacuum Producers TPR Turbopumps with TPR designation are parallel connected twin impeller belt driven units. Cooling air is introduced into the unit through an adjustable vacuum relief valve. The vacuum pressure in the system can be held constant when different outlets are opened. The turbopumps are equipped with thermal overload protection on the outboard bearing which will trip out when bearing temperature becomes excessive. A back flow valve is built into the unit on the inlet side. TSR Turbopumps with TSR designation are series connected two stage belt driven units. Cooling air is introduced into the pump through a slot between the two stages. In this way the second stage cools the first stage indirectly, allowing the pump to run at extremely high vacuum and low airflow without overheating. The turbopumps are equipped with thermal overload protection on the outboard bearing which will trip out when bearing temperature becomes excessive. A back flow valve must be optionally installed on the inlet side of the unit when several units are to be installed in parallel.

Filter Units 5 About Dustcontrol Filter Units An extraction system should always be equipped with a filter unit. The filter unit separates coarse material in the cyclone body of the unit and fine dust in an internal arrangement of conical pleated cartridge filters. Pleated filters have very high filter areas in relation to their physical size. The filter units therefore have high capacity while maintaining compact overall dimensions. Filters are cleaned with reverse pulse which results in very effective cleaning, long filter life and low maintenance. Normally the filter units are equipped with a plastic sack for collection of the extracted material but other types of discharge arrangements can also be installed. General In the filter unit, dust is separated from the air in several steps. the cyclone will separate particles down to a size of 1/ mm. the filter will separate particles which go through the cyclone. The dust laden air is introduced into the cyclone at a high velocity. Through centrifugal force the dust particles, with higher relative mass than the air molecules, are forced outward toward the wall of the cyclone and fall toward the bottom. The air flows toward the centre of the cyclone and through the filter. Filter Loading Permissible air-flow determines the air velocity through the filter material, known as filter loading. Consider also inlet/outlet velocities. Permissible filter loading varies with dust type. Dust Type Permissible filter loading ()/m Stone 1 Concrete 1 Wood 16 Cement 1 Plastic 1 Graphite 6 Carbon black 6 Welding fume 6 Fibreglass 6 Example: For the extraction of welding fume, the maximum permissible flow in the S 3 will be: 6()/m x 3 m filterarea = The velocity of the air through the inlet and outlet should not exceed 3 m/s. When one filter unit does not have sufficient capacity, several units can be connected in parallel. 5
