VPS Vacuum Pump Unit is widely
used in various types of large-scale transformer installation and maintenance for
high-efficiency vacuum drying and vacuum oiling. Quick air pumping, energy
consumption, LCD display, mobile and flexible features. The leakage rate of the
unit is less than 1%, the vacuum system is equipped with anti-oil-back device
and phase sequence automatic commutation system to prevent the vacuum pump from
VPS Vacuum Pump Unit adopts
air-cooled German Leybold rotary vane vacuum pump and roots pump, working vacuum is 50Pa and max working
vacuum up to 10 Pa in the running, the ultimate vacuum is 1-3Pa. It has
features of quick start, high pumping speed, stable performance, easy to operate.
1. Applying for vacuum drying and
vacuum measurement of transformers, tap changers, auxiliary switches and other
2. Cooling type: natural
air-cooled. The vacuum pump exhaust port is provided with device for condensing
and collecting moisture.
3. The control system has the
perfect protection and alarm functions with phase sequence, phase, overvoltage,
undervoltage, leakage detection and protection of all faults are the
corresponding warning light prompt.
4. VPS Vacuum Pump Unit uses
automatic control function, the roots pump automatically starts.
5. System settings Oil level
detection devices: oil and gas separators, oil storage tanks and photoelectric
switches on the transformer and vacuum pump protection, to prevent the oil
pumped out by the vacuum pump. When the photoelectric switch detects the oil is
pumped to the oil-gas separator, the system forced shutdown, suggesting that
oil, troubleshooting, the system returned to normal.
5. Vacuum pump with self-check
valve, vacuum pump interlock, in the power outage or vacuum pump stop
automatically closed when the check valve, in addition to insurance in the
exhaust port is also equipped with a vacuum solenoid valve, the vacuum or
vacuum pump stop solenoid valve closed , To prevent any situation when the
reverse vacuum pump oil into the GIS chamber, theoretically put an end to a
6. Electronic vacuum gauge and
McGregor vacuum gauge are installed in the back of the total valve to
facilitate the detection of the vacuum transformer, McNair vacuum gauge with
the corresponding valve, do not have to shut.
7. Axial fan: rotary vane pump
and Roots pump separation of water vapor and light oil for cooling, collection
and emissions, to protect the vacuum pump oil from pollution, enhance the
pumping capacity of the vacuum pump to improve the working vacuum. No increase
in the pumping capacity of the case, whether it is oil or vacuum unit vacuum
machine work greatly improved.
