Description

Application:

HOPU ZYD Series Double-stage High Vacuum Transformer Oil Purification Plant with weather proof, dust and water resistant enclosure is for outdoor usage. The Process of this machine is able to increase and maintain transformer oil's dielectric strength, including the removal of free and soluble water, free and dissolved air and gases and other particulate matter.

The system is designed for processing transformer oil and other insulating oil in workshops, in storage tanks or directly in transformers (energized or de-energized transformers). And it can be used as an independent vacuum source with functions of vacuum drying and vacuum oiling.

Advantages:

1) The machine’s enclosure is made of metallic material with high quality sealing rubber strip, so the machine is weather proof, dust and water resistant, so it can be used outdoor.

2) Unique vacuum dehydration, degassification system, adopt stereo-evaporation technology. Duplex 3D stereo-evaporation, eliminating the liquid water quickly.

3) The vacuum system uses the roots pump as the main pump and the rotary vane vacuum pump as the primary pump. Fast start-up, large pumping speed, stable performance, and high ultimate vacuum of less than 5Pa.

4) Low-load heating: Adopt advanced internal and external double-tube heat radiation indirect heating technology.

5) The machine adopt interlocked protective system, which connect oil pump, heater and liquid level sensor so as to avoid heating with no liquids, pumping with no liquids, oil leakage and electricity leakage. If there is any fault, machine will be power off automatically.

6) Low noise, easy operation, long maintenance interval, low energy consumption, low operating cost.

7) Strong ability to remove impurities: ultra-large area cylindrical precision filter element, with high filtration accuracy, easy installation and replacement.

8) It can evacuate the electric equipment separately, such as the transformer. Also it can be used to dry the electric equipment and input the oil into the electric equipment under the vacuum state.

9) The machine adopts Siemens fully automatic PLC, double floating ball liquid automatic controller and pressure automatic-protector which can make sure the machine works online for 150 hours continuously without person.

10) Installs a digital flow meter to display real-time and cumulative flow rates.
