It is off at BT1 = 35 °C4. PUTTING INTO OPERATIONPutting into operation is performed at the customer after it is connected to the machine lubrication and electric circuit. After transportation it is necessary to check the assembly of the aggregate parts, especially seating of electric motors and pumps.Putting into operation shall be done only by the equipment fabricator or by the persons trained by the fabricator who will be approved by the fabricator in written.During putting into operation the whole course of putting into operation shall be documented in the book. Putting into operation shall be done in accordance with the following points:4.1 Oil filling of gearboxGearbox filling shall be done with filtration filling unit with possibility of filtration min. 25 μm. Prescribed liquid is mentioned in technical parameters p.1.1. Level shall be checked on the level indicator (pos. 122)4.2 Flushing and testingPrior to putting into operation it shall be checked, whether the direction of electric motor turning corresponds to the data on the pump plate, on right-handed pump the direction of turning is in clockwise direction, with a view from electric motor to the pump. Pressure valve is released. Having performed the check, start the pump and let it run without pressure. During commissioning check and refill working fluid.After flushing it is necessary to take off oil sample from the gearbox to estimate liquid purity. If oil meets purity class 9 according to NAS 1638, it is possible to start with the lubrication equipment testing.Flushing shall be done also after long shut-downs and bigger repairs that involve pipe distribution.4.3 Working pressure set upMax. working pressure in lubrication circuit shall be set up by means of safety valve to 10 bar. Pressure is adjusted with the screw turning ( supply – pressure raise).Maximal working pressure can be adjusted at closed closing valve (pos. 120) at the outlet from the lubrication aggregate.4.4 Flow rate signalingFlow rate switch (pos. 114) signals liquid flow rate at the outlet from the aggregate.4.5 Pressure controlPressure can be controlled by means of built-in pressure gauge (pos. 109).4.6 Oil filtrationOil filtration is assured with double outlet filter (pos. 117). Filter is equipped with electric sensor of clogging and by-pass valve in case of clogging. Filtration degree is mentioned in technical parameters.Filtration insert substitution shall be done in case of :- impurity indicator signal (for more than 2 minutes)- after the first 500 hours after putting equipment into operation or once a year (according to the laboratory oil analysis – performs specialized firm ) -oil substitution4.7 Temperature controlOil temperature is measured with temperature sensor (pos. 117). Oil temperature can be checked with thermometer (pos. 118) – only when the pump runs.4.8 Level controlOil level height is controlled with level switch (pos. 122) that sends electrical signal if oil level in the gearbox is minimal and interlocks the drive, when oil level drops below emergency level.5. EQUIPMENT OPERATIONThe equipment operators shall be familiar with:a) the work of lubrication circuit in accordance with the functional diagramb) have basic knowledge about maintenance of lubrication equipmentc) safety rules and principles of safe work during manipulation with mineral oilsd) the function of lubrication elements and the way of their controlThe operators duties are :-performance of preventive examinations of equipment-control of hydraulic elements at adjustment-determination of requirements for equipment maintenance-maintain the book documenting running of the lubrication equipment and performed repairs6. EQUIPMENT MAINTENANCEMaintenance is an important condition for operation of the lubrication equipment. Any interferences for the maintenance of equipment are performed when it is out of operation (without pressure) and by the workers specially assigned for this work who are responsible for this work and properly trained for this activity.A part of the equipment maintenance Is the implementation of so called inspection system, duly documented with the book and checked, in which the following data are especially mentioned :-examination of equipment, in particular connections of pipe distribution-record of finding the first drop or oil leakage and the way of removal-assignment of repair date and responsible worker-confirmation about performance of the repair and its control-parallel oil check performed by specialized firm at least once a month and oil refill, as requiredImplementation of the inspection system is a necessary presumption foreventual claim procedure.Prior to eventual repair all lubrication equipment shall be cleaned in order to prevent from dirty entry into oil during repair. All the repairs are performed when agreed with the equipment operators.Especially for the first 3 months after passing-over the equipment to the User it is necessary to follow-up leaks of the pipe distribution and the connections shall be regularly retightened.At each long equipment shut-down it is useful :-to check the level height, or refill oil (only assigned quality with auxiliary hydrogenerator through the filter 25 m)At each repeated start :-to check oil level-to check filter cloggingFurthermore, during operation it is necessary to follow-up :-operation oil temperature-equipment noise7.
