🛠️Product Function & Application

RNVS series vacuum pumping equipment is used to evacuate the gas in the transformer, so that the iron core, coil and insulating material in the transformer are completely exposed to the high vacuum environment. In a high vacuum environment, the moisture absorbed by the iron core, coil and insulation material evaporates into the air and is discharged by the vacuum pump, thereby achieving the role of drying the transformer.

Vacuum Pumping Process

It is widely used in the vacuuming process in the production, installation and maintenance of many electric power equipment, like electric power transformer, capacitor etc. It can offer high efficiency vacuum evacuating, vacuum injection and vacuum oiling for transformers, and is also used in industrial processes such as vacuum drying, distillation, and coating.

Technical Features
  • High Vacuum Degree: Two-stage or three-stage vacuum pumps reach below 3~5pa (standard) or 0.1pa (deluxe).
  • Stable Components: Utilizes high-quality brands for vacuum pumps, Pirani electronic gauges, and vacuum transmitters.
  • Energy Saving Technology: Automatic pump management where secondary levels stop once set values are reached.
  • Super Fast Pumping: Vacuum and Roots pumps work synchronously, increasing efficiency by up to 40%.
  • Safety Protections: Includes liquid level sensors, power phase protection, and motor overload protection.
  • Intelligent Control: PLC automatic system with one-key start/stop and memory storage for historical data.

Frequently Asked Questions
What is the primary function of the RNVS series? The primary function is to evacuate gas and moisture from transformers, providing high vacuum environments for drying, vacuum injection, and oiling.
How does the energy-saving technology work? Once the set vacuum level is reached, the PLC automatically stops the secondary stage pump while the primary pump maintains the operating vacuum.
What vacuum pressure can be achieved? Standard two-stage systems reach 3~5 Pa, while deluxe three-stage equipment can reach levels below 0.1 Pa.
Is the machine suitable for explosive or corrosive gases? No, it is not suitable for air containing high amounts of powder, water, oxygen, or explosive, corrosive, and poisonous chemical substances.
Does the machine offer safety protection for the motor? Yes, the PLC monitors for power phase issues, incorrect voltage, and motor current overloads to prevent damage.
How long is the warranty period for this equipment? The machine comes with a 24-month warranty covering manufacturing defects and workmanship.
