65KW Single-Stage Oil Filtering Machine: Vacuum Transformer Oil
Purifier with 6000L/H Capacity
Description
Sino-NSH-VF is a dehydration and degassing unit that utilizes both
thermal and vacuum processing techniques. Compared to the
Sino-NSH-VFD series, this unit is more tailored for applications
requiring smaller volumes of oil or lower capacities.Primarily, the
Sino-NSH-VF is employed to enhance the properties of insulating
oils found in electrical transformers and other oil-filled
electrical equipment. It efficiently removes both dissolved and
free water, dissolved gases, and particulate impurities, thereby
elevating the special indexes of the insulation oil.By integrating
vacuum flashing evaporation technology with delaminating
gradual-close filter technology, the Sino-NSH-VF achieves optimal
oil purification performance. Furthermore, the combination of
thermal and vacuum processing enhances the breakdown voltage, which
can be increased from 25kV to over 60kV.The Sino-NSH-VF boasts an
optimized structure and safe control mechanisms, fulfilling the
comprehensive needs of transformer manufacturers and service
providers.
General
VF series transformer oil single-stage vacuum oil filter is widely
used in power industry and large industrial and mining enterprises
to purify the insulation oil of power transmission and
transformation equipment. Can also be used for hydraulic oil,
lubricating oil purification treatment. It can effectively remove
water, gas and impurity particles in oil, improve insulation
strength and oil quality, and ensure the normal operation of
electrical equipment.
VF series single-stage vacuum insulation oil purifier is mainly
used to extend the lifetime of oils used in transformers, circuit
breakers, mutual inductor, voltage regulators and switch gear, or
to inject the insulating oil into the transformers.
Equipped with regenerators, it can improve the effect of de-acid,
de-color and remove dielectric and acid more effectively. The value
of breakdown voltage will increase from 15KV to 65KV. The
performance and lifetime of insulating oil will improve and extend
awfully after purification and regeneration.

Characteristics
NSH-VF series transformer oil single-stage vacuum oil filter
features:
A. High precision filtration system, high quality filtration
elements and progressive multistage filtration help to effectively
remove mechanical impurities from oil. The filter has a
self-checking function to detect the status of contaminants.
B. The heating system is made of stainless steel and adopts
optimized pipeline design to ensure even heating and stable oil
temperature.
C. Equipped with automatic temperature control system, automatic
liquid level control system, automatic pressure protection system
and high-quality main components, to ensure the high reliability
and perfect performance of the equipment.
D. The single-stage vacuum oil filter supports online operation
without supervision and has an indicator indicating the operation
status.
E. Adopt electric control interlock design. The vacuum system, oil
pump system and heating system are interlocked in the control to
avoid the adverse effects of incorrect operation.
F. Equipped with indication to replace filter and overload
automatic stop device.
G. Equipped with emergency stop and alarm lights to prevent leakage
and power overload, so as to protect the motor.
H. With phase sequence, phase break protection function and normal
control, can suddenly stop
I. The machine can be operated online and offline. In addition, it
can also be used as an independent vacuum pump and vacuum oiling
equipment for oil-immersed electrical = equipment. After
purification, the technical parameters and performance of the
transformer oil will be significantly restored. Under ideal
conditions, the breakdown voltage of the oil can reach 75-80kV.
Main components
a.Pre-filter:
Utilizes a 50-80mesh strainer to remove any large particles
b. Electric heater:
Oil Heater System assures less than 1.0 w/cm². During the heating
process, the deterioration of the oil caused by overheating is
avoided. The oil temperature can be adjusted between 20℃ to 80℃.The
heater is controlled manually or automatically. The heater will
stop automatically when the oil temperature reaches a certain
degree. Being installed with safety protection devices, the heating
system is secure and reliable. The heater will stop operation
automatically when the oil volume of inlet is too low to avoid the
damages of the heater.
c. Vacuum chamber:
Utilizes coacervation technology, coalescing technology, separating
technology and refined purification technology. To remove free,
soluble water, free and dissolved gases. The oil-level floating
ball or infrared liquid level automatic controller system are
installed in the vacuum vessel to control the oil level so as to
avoid the oil being
suctioned into vacuum pump in the operation. The new innovation of
eliminating froth can avoid the oil being suctioned into vacuum
pump.
d. Oil cooler:
Connected to between vacuum chamber and the roots pump, the vacuum
pump to avoid oil entering roots pump and vacuum pump. Secondly, to
cool the heated air.
e. Oil discharge pump:
Featuring high suction capabilities removes oil from the processing
chamber and discharges the oil through a filter before it is
directed either through the discharge port or is re-circulated
within the system.
f. Fine filter:
Oil receives its final “polishing” treatment by passing through a
high performance element. The filter is rated to capture99.5% of
particles greater from 5 to 10 micron absolute.
g. Sampling probe:
Two (2) sampling probes shall be provided, one for the incoming oil
and one for the processed oil.
h. Inlet&discharge valves:
Manual valves are provided for the inlet and discharge connection.
i. Manual re-circulation valve:
One manual valve is provided for re-circulation purposes.
j. Transformer dry-out connection:
One transformer dry-out connection.
k. Control panel:
Instrumentation, alarms& interlocks instrumentation&electrical
controls are located in NEMA 12 type enclosure. Several pilot
lights are provided to indicate operational status(on/off) of key
components and alarm conditions.
