NAS 9 Hydraulic Filtration System

Hydraulic Oil Filtration system with common off-line oil filtration comes with Oil heating and heat exchanger system.

The main Filtration system comprises of following sub systems.

• Oil Conditioning system.
• Oil filling system.
• Oil flushing system.
• Oil draining system.
• Oil Collection system.

• Oil Conditioning System :

  Suitable oil conditioning system to achieve required level of purification and temperature shall be designed as referred in the hydraulic circuit of this document. An offline conditioning system, which includes oil pump, heating unit, oil filters and necessary instrumentation shall be part of this supply. The proposed system shall achieve required level of purification (NAS 9) and temperature (Max. 70^.C) within the acceptable level of Tolerances.

• Oil Filling System :

  Appropriate hydraulic connection shall be made with test transmission.

  Manually, conditioned and metered oil from clean oil compartment of the reservoir shall be pumped in to the test unit oil supply port. After completion of testing, operator shall remove the QD from the test transmission and park the QD at designated place.

• Oil Flushing System :

  After initial filling of the metered quantity, oil circulation shall begin thru appropriate oil supply and drain ports. During the entire time of the performance study, respective oil pump shall circulate the oil within the test component.

• Oil Draining System :

  After completion of performance test, drain pump shall drain the oil from the drain port of the test component and shall transfer the oil into dirty compartment of the filtration system.

• Oil Collection System :

  An oil collection tray shall be provided beneath pallet assembly so as to collect the spilled oil from test transmission if any. A pump Periodically shall pump the collected oil into dirty compartment of the Filtration system.
