Page 16: Connection To The System
Installation Connection to the System Before connecting the TRIVAC B, remove the shipping seals from the connection flanges (7/2) and (7/3). Caution Retain the shipping seals in case you need to store the pump in the future. The pump is shipped with intake and exhaust flanges mounted for hori- zontal connection of the connecting lines. -
Page 17: Electrical Connections
Installation Electrical Connections Before wiring the motor or altering the wiring, ensure that mains supply Warning for the pump is off and that it can not be applied inadvertently. In order to prevent the pump from running up unexpectedly after a mains power failure, the pump must be integrated in the control system in such a way that the pump can only be switched on again manually. -
Page 18: Operation
Installation Operation Start-up Each time before starting up check the oil level. On initial start-up, after prolonged idle periods or after an oil change, the specified ultimate pressure cannot be attained until the oil is degassed. This can be done by running the pump for approx. 30 min. with the intake line closed and the gas ballast valve (7/5) open. -
Page 19: Pumping Of Condensable Gases And Vapours
Installation 4.2.2 Pumping of Condensable Gases and Vapours With the gas ballast valve open (position I) and at operating temperature, TRIVAC B pumps can pump pure water vapour up to the water vapour tole- rance specified by the technical data. If the vapour pressure increases above the permissible level, the water vapour will condense in the oil of the pump. -
Page 20: Shutdown
Installation Shutdown Under normal circumstances, all that you need do is to electrically switch off the TRIVAC B. No further actions will be required. When pumping condensable media let the pump continue to operate with the gas ballast valve open and the intake line closed before switching off (see Section 4.2.2). -
Page 21: Maintenance
Operation Maintenance Disconnect the electrical connections before disassembling the pump. Warning Make absolutely sure that the pump cannot be accidentally started. If the pump has pumped harmful substances, contrary to what has been stated in Section 3.4, ascertain the nature of hazard and take adequate safety measures. -
Page 22: Checking The Oil Level
Maintenance Key to Fig. 9 Oil-fill plug Oil-level mark maximum Oil-level mark minimum Oil-drain plug Fig. 9 Oil change Checking the Oil Level During operation of the TRIVAC B the oil level must always remain between marks (9/2) and (9/3) on the oil-level glass. The amount of oil must be checked and topped up as required. -
Page 23: Oil Change
Maintenance Oil Change Before pumping oxygen (or other highly reactive gases) at concentrations Warning exceeding concentration atmosphere (> 21 % for oxygen) it will be necessary to use a special pump. Such a pump will have to be modified and degreased, and an inert special lubricant (like PFPE) must be used. -
Page 24: Cleaning The Inlet Screen
Maintenance Cleaning the Inlet Screen A wire-mesh sieve is located in the intake port of the pump to act as a dirt trap for coarse particles. It should be kept clean to avoid a reduction of the pumping speed. For this purpose, remove the inlet screen (2/2) from the intake port and rinse it in a suitable vessel with solvent. - Page 25 Maintenance Key to Fig. 10 Oil case Spring buckles Demister Frame for demister Hex. socket screws (4 pcs.)
