Product Description REXON Vacuum Pump Unit, Roots Vacuum Pumping Set, Transformer Evacuating Machine -Model RNVS-150, Capacity 540 M3/H--Equipped with PLC programming system and 10 10-inch colourful touch screen for operation--It can be operated in both fully automatic & manual bothThis REXON vacuum pump unit integrates a robust backing pump with a Roots pumping set to achieve fast evacuation and stable deep vacuum for transformer manufacturing, installation and maintenance. Operating in high vacuum makes absorbed moisture in the core, windings and insulation evaporate and be discharged, effectively drying the transformer and preparing it for vacuum oil injection. Two/three-stage options provide ultimate vacuum of ≤3-5 Pa or <0.1 Pa. REXON's green, energy-saving logic halts higher stages at setpoint while the first stage holds pressure; the synchronous-start option with liquid-cooled Roots exhaust raises efficiency by about 40% and reduces thermal stress. Standard JOYSUN pumps and PANGU Pirani gauge ensure reliability; ATLAS/LEYBOLD pumps and LEYBOLD transmitters are available. PLC one-key start, level detection, power-phase/voltage and motor-overload protections safeguard 24/7 operation. Result: cleaner, drier insulating oil with higher dielectric strength and reduced dissolved gases for safer, longer-lasting transformers.Product DescriptionI. Product function introductionRNVS 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.II. Application:RNVS series transformer evacuation system/ vacuum pump set is a new type of vacuuming equipment developed and produced by our company. It is widely used in the process of producing vacuum condition for various equipment. Its vacuum pressure can reach much lower than any other products in the same field.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 it is also used in the technical process of industrial production, such as vacuum drying, vacuum distillation, vacuum wielding, vacuum coating etc. It is not suitable for the vacuum process for air and gases containing too much powder, water and oxygen as well as explosive, corrosive, poisonous and chemical substances.III. Features:1. High vacuum degreeTwo-stage or three-stage vacuum pumps are used (two-stage vacuum pumps are used for the pumping volume of 4000 cubic meters and below, and three-stage vacuum pumps are used above 4000 cubic meters). The ultimate vacuum energy of the two-stage vacuum equipment can reach below 3~5pa, and the ultimate vacuum energy of the three-stage vacuum equipment Below 0.1pa.2. Highly stable and reliable main componentsThe vacuum pump is China JOYSUN brand for standard type, and Germany ATLAS/LEYBOLD brand as our deluxe type. Pirani electronic vacuum gauge is China PANGU Brand as standard type, and Germany LEYBOLD brand vacuum transmitter as deluxe type. And roots vacuum pump is China famous JOYSUN, HUAXINNANGUANG, Germany ATLAS, LEYBOLD, and BECKER brand as optional items.3. REXON 's unique environmental protection and energy saving technologyWhen the vacuum of the container reaches the value set by the customer, the vacuum pump above the second level stops running, and the operation of the vacuum pump at the first level maintains the operating vacuum, thereby realizing energy saving.4. Super fast pumping speed: Vacuum Pump & Roots Pump start work at the same time/synchronously, and the efficiency is increased by 40% (Optional)The equipment automatically adjusts the pressure difference between the inlet and outlet of the Roots Vacuum Pump to ensure that the outlet of the Roots Pump is always at the highest pressure, and the inlet gas of the vacuum pump always maintains the highest compression ratio. A liquid-cooled heat dissipation device is installed at the exhaust port of the Roots pump, which not only prevents the Roots Pump from overheating, but also reduces the volume of compressed gas at the outlet of the Roots Pump. Other brands of Roots Vacuum Pumps need to be reduced to 1000-2000pa before starting.5. With liquid level protectionThe oil and gas separator is equipped with a liquid level sensor. When the PLC detects the liquid level, the vacuum unit stops running and issues an alarm message to prevent the possibility of contamination of the vacuum pump oil.6. With power protectionWhen the PLC detects that the power supply is out of phase, out of phase, or the voltage is too high or too low, the device enters the protection state and issues an alarm message to prevent vacuum damage due to motor reverse rotation.7. Equipped with motor overload protectionWhen the PLC detects that the motor current exceeds the set value, the device enters the protection state and issues an alarm message to prevent the motor from being damaged.8. Simple operation mode (Optional)Using PLC intelligent control, the equipment starts and stops with one key, without manual intervention.9. Memory storage and query (Optional)The PLC program can record historical work data, and the user can query the operating vacuum of the equipment at different times at any time.Detailed PhotosMain Parts: Product ParametersTechnical ParameterModel RNVS-70Model RNVS-150Model RNVS-300Model RNVS-600---Total VacuumPumping Capacity252m3/h540m3/h1080m3/h2160m3/hFirst Stage PumpRotary Vacuum Pump Pumping Capacity 65m3/h100m3/h200m3/h200m3/h + 200m3/hFirst Stage PumpRotary Vacuum PumpModelOption A:China JOYSUN X-63Option A:China JOYSUN X-100Option A:China JOYSUN X-200Option A:China JOYSUN X-200 * Nos. 2Option B:Germany ATLAS GVS-65Option B:Germany ATLAS GVS-100Option B:Germany ATLAS GVS-200Option B:Germany ATLAS GVS-200 * Nos. 2Option C:Germany SV-65Option C:Germany SV-100Option C:Germany SV-200Option C:Germany SV-200 * Nos. 2Second Stage PumpRoots Vacuum PumpPumping Capacity 252m3/h540m3/h1080m3/h2160m3/hSecond Stage PumpRoots Vacuum Pump Model ZJP -70Brand: China HUAXINNANGUANGZJP -150Brand: China HUAXINNANGUANGZJP -300Brand: China HUAXINNANGUANGZJP -600Brand: China HUAXINNANGUANGUltimate Vacuum Degree(Pa)3~5 Depends on Booster ModelTotal Electric Power (kw)2.65911.5Power Supply380V (3phase, 4wires), 50Hz, - or as per your requirementVacuuming Connection Port Diameter(mm)DN32DN40DN50DN65Overall Dimensions(m)1.20×1.10×1.511.32×1.02×1.571.37×1.07×1.611.77×1.30×1.92Onsite ProjectsOther Equipment You May NeedOur Related Equipments for Transformer Maintenance: Double Stage Vacuum Transformer Oil Filtration & Purification Machine Dry Air GeneratorSingle Stage Vacuum Transformer Oil Filtration & Purification Machine BDV Tester Company ProfileChongqing Rexon Oil Purification Co., Ltd is a leading oil purifier manufacturer in China, which engages in developing, producing, selling a series of oil purifier such as transformer oil purifier, turbine oil purifier, engine oil purifier, lube oil purifier, cooking oil purifier and so on.
