CHARACTERISTICS OF OPERATIONS

The units of HYDROSYS series consist of a liquid-ring vacuum pump of the series TRH, TRS, TRM, TRV, of an air-liquid cyclone separator, of a heat exchanger, all units being mounted on one compact frame. During the operation, the vacuum pump ejects the sucked gas from the delivery port and also part of the service liquid which is present inside it and which must be continuously made up. The air-liquid mixture is delivered to a cylindric tank where the separation occurs: the gas comes out from the upper delivery port of the tank, ready to be sent again to the vacuum pump. During the suction and compression cycle, the vacuum pump transfer all the work carried out under the form of heat to the service liquid, which, of course, before being recycled, shall be cooled down either by means of a heat exchanger (total circuit) or by the supply of fresh liquid from outside (partial circuit).

• The operation by TOTAL RECIRCULATION does not require an external supply of operation liquid if not only the one that is evaporated, if any, or that is ejected together with the discharge gases. The correct dimensioning of the heat exchanger only requires a minimum amount of fresh liquid (usually water) so that the ideal temperature can be maintained for the correct operation of the vacuum pump (please remember that the hotter the operation liquid is, the more loss of suction capacity the pump suffers both in flowrate and in maximum vacuum degree: see the technical information given in our catalogue for vacuum pumps). This system is particularly suitable, when the service liquid or the condensable sucked gases cannot be eliminated outside due to reasons of pollution or to recuperation requirements and cost reasons (see our diagram on page 6).
• The PARTIAL RECIRCULATION operation, instead requires a constant supply of fresh liquid from outside, that is of the same kind as the one circulating inside the unit, since the mixing of the external fresh liquid with the one that is inside the unit keeps the constant temperature of the fresh liquid at the vacuum pump inlet. According to the amount of liquid supplied from outside, the same amount will be eliminated through the discharge located on the center line of the tank (see drawing on page 6). This type of operation is sometimes advantageous if this is required by the flowrate and vacuum characteristics, (for example low vacuum or intermittent operation) or when the service liquid is not polluted and does not create elimination problems. Of course, since a cooling liquid with correct amount and temperature is not available, this remains the only alternative to the total circuit. Several accessories are available to meet particular requirements of plant, of process and of maintenance, and furthermore, it is possible to design particular units, upon request, in co-operation with our Sales Office.

The HYDROSYS series can also be used to work as a compressor up to a maximum pressure of 2 bar, higher than the suction pressure by using tanks and accessories according to ISPESL standards.

CHARACTERISTICS OF OPERATIONS

OILSYS systems includes a liquid ring vacuum pump from our series TRH, TRS, TRM, TRV, a separator tank which also as a frame, heat exchanger and oil demister to remove oil fumes.

Mineral oil, or equal, is used as service liquid. This fluid has physical properties such that enhances to pump performance and attainable amximun vacuum particularly for vacuum < 100 mbar. The gas handled by the vacuum pump is discharged with some of the service oil into the special frame which acts as gas/oil separator and allows separation from the oil of any evacuated condensables.

The oil is returned to the vacuum pump by means of a circulation pump after being cooled to about 60°C (140° F) through the heat exchanger. The gas is vented after being filtered of any oil through the specially engineered oil demister filter.
A pressur gauge at the filter housing will indicate over pressure when the oil demister filter is plugged and needs replacement. Inspection openings are strategically located at the separator tank-frame to facilitate maintenance and cleaning.

Contrary to rotary vane pumps, these liquid ring vacuum pumps do not require lubrication, therefore contamination of oil by condensables or solid particles is not demaging.

The rugged and reliable construction of the liquid ring vacuum pump is matched by the generously engineered built OILSYS system.

The three-lobe rotor of every  POMPETRAVAINI – BORA product is the evolution of the classic bi-lobe design, shaped like an “eight”. This design ensures higher bending stiffness, and lower pulsation amplitude that consequently reduces vibration. The economic advantage in the bearing life is appreciable. The compressor noise is remarkably decreased as well.

The synchro-gears of every  POMPETRAVAINI – BORA product are case hardened and tempered. Gears are accurately ground to ensure optimal timing. The “long addendum” involute design gives maximum efficiency with virtually silent mechanical operation. This design allows the vacuum boosters to be installed without a sound canopy.

The mechanical noise is kept to a minimum as a result of accurate design and assembly. The gear lubricant is a long lasting, low viscosity PAO oil that enhances the machine cooling. The lubricant can be supplied “food grade” for certain applications. These features all help to decrease the machine’s life cycle cost.

Pump’s body, sump, and covers are assembled with flat gasket (blowers/exausters) or O-Ring seals (booster HV) to ensure maximum tightness. This results in increased reliability which decreases maintenance costs.

The sealing of the rotors is achieved with labyrinth seals, which do not contact and therefore do not create friction. This is ideal for the rotor’s high rotation speed. This solution saves money due to the decrease in energy dissipation and absence of any other expensive cooling system.

Shaft sealing with double Silicon Carbide/Graphite mechanical seals ensures high reliability and durability. The diameter of the shaft is specifically designed in order to maximize strength and reduce peripheral speed and the associated friction. Low maintenance and decreased risk of down time are the advantages that result in maximized cost savings.

VOLUMETRIC BLOWER

The volumetric blower is an ‘oil-free’ lobe pump for air or non aggressive/non explosive gases suitable to operate with a maximum backpressure of 1000 mbar (g) at discharge and a maximum vacuum of -500 mbar (g), within the allowable temperature limits.

• Standard version with rotors supported by bearings on both ends, available for models 163 through 883. Vertical or horizontal inlet-outlet flanges available.
• The compact version, which has a cantilever design and an axial inlet, is available for models 73 and 103. The axial inlet significantly improves the volumetric efficiency above 2500 RPM. The energy consumption is much lower if compared to the traditional design, thus ensuring sensible savings on the running costs.

EXHAUSTERS AC

The air cooled (AC) Exhauster is an ‘oil free’ rotary lobe pump for air or non aggressive/non explosive gases suitable to operate with a maximum vacuum of -0.85 bar (g), within the allowable temperature limits.
