Generally, hydraulic oil is to be maintained at very high quality of Purification. The Oil often having large sizes of particles is passed through coarse type filter, to trap the large sized particles. Having taken care of micronic and sub-micronic particles, it is further finely cleaned by electro-statically, operated hydraulic oil cleaner & brought to the international standards.
The oil is pumped and passed through a cleaning cell. An electric field is created in this cell by a high voltage applied in between two electrodes. Oil is then passed through the field. The fine particles are attracted towards positive electrode and are collected on collector papers as sludge, thereby purifying the oil at a higher degree of purification.
Best performance results of the hydraulic oil are obtained at following conditions:
1. Temperature : Less than 60 º C.
2. Viscosity : Less than 300 centi. Stokes.
3. Moisture : Less than 500 PPM
• NEC 50 & NEC 100 purifiers are not suitable for following conditions
1. Oils with moisture more than 500ppm, but additional dehydrator unit can be connected to the system & good performance results are obtained.
2. Synthetic Oils
3. Any conductive oil.
4. Oil with Detergent dispersants.
Specifications : Cleaning Tank Capacity : 50ltrs. Cleaning rate : 8 to 10 ltrs per min. Power Supply : 230 volts, A.C. Single phase 50Hz. with Earth.
Specifications : Cleaning Tank Capacity : 100ltrs. Cleaning rate : 16 to 20 ltrs per min. Power Supply : 230 volts, A.C. Single phase 50Hz. with Earth. THE PURIFIERS--NEC50 & NEC100 :
• No chemical treatment is given, hence no contamination or no change in chemical structure occurs.
• Operation is ‘Round the clock’ as both the machines are continuously rated.
• The unit is easy for installation. Inlet / Outlet hoses are to be connected to the equipment. A power supply connection is to be given.
• For removal of moisture, if oil is more contaminated with moisture, additional dehydrator unit is to be connected to the system
• To avoid break down of main unit. This enhances system performance.
• This is completely indigenous as no component is imported. Hence no dilemmas regarding import of paper or spares exist.
• Robust HV Transformer design and tripping circuit improve reliability even under rugged working conditions.
