(57) The invention relates to oil supply systems for turbomachines. The purpose of the invention is to increase the efficiency of oil purification (M) from air and gas bubbles. Gas bubbles emitted from the oil flowing through the channels 5 from the inlet pipe to the outlet pipe are picked up by the visor 10 and directed through the slots 9 into the cavities 8 formed by plates 6 and 7. When the ejector 18 is operating, the gas-saturated M through the pipeline (T ) 14 enters the expansion tank 11, where it is finally degassed. The free gas is removed from the tank by means of T 16 and the oil separator 17. Purified M through the float valve 12 and T 13 enters housing 1. 2 sludge.

The invention relates to a compressor design and can be used in oil supply systems of a turbomachine.

The aim of the invention is to increase the efficiency of oil cleaning from air and gas bubbles.

Fig. 1 schematically shows an oil tank: in Fig. 2, view A in Fig. 1.

The oil tank comprises a housing 1, nozzles 2 and 3 of the inlet and the outlet, a package of inclined partitions 4 forming the channels 5 for the oil. The partitions 4 are made of two plates 6 and 7 with the formation of cavities 8 between them. The plates 7 have slots 9 with peaks 10 arranged in horizontal rows along the height of the plates 7. The tank is equipped with an expansion tank 11c installed in its upper part 11c and a float valve 12 and a drain pipe 13. The expansion tank 11 is connected by a pipe 14 with cavities 9 partitions 4, made with a sealed end wall 15 in its upper part, and a pipe 16 with an oil separator 17 and an ejector 18,

The tank functions as follows.

The contaminated oil through the inlet pipe 2 enters the tank body 1, through the channels 5 it moves to the outlet pipe 3 and through

the slots 9 fill the cavities 8. The gas bubbles emitted from the flow of oil flowing through the channels 5 rise up, are caught by the visors 10 and are directed through the slots 9 into the cavity 8. When the ejector is in operation, conditions are created to move the gas-saturated oil through pipeline 14 of cavities 8 into the expansion tank 11, where the final degassing of the oil and the removal of gas through the pipeline 16 and the oil separator 17 from the tank take place. Oil purified from gas from the expansion tank 11 through the float valve 12 and the drain pipe 13 enters the tank.

Claims (1)

Claims of the invention: Oil tank according to auth.St. No. 1605081, characterized in that, for the purpose of increasing the efficiency of oil cleaning from air and gas bubbles, the tank is equipped with an expansion tank installed in its upper part with a float valve and a drain pipe, a plate, the cavity-forming elements are provided with an airtight end wall, in this case the expansion capacitance is communicated through a dead-end pipeline with cavities formed by plates, and an oil separator with an ejector.
