First of all, before we choose Transformer Oil Filtration Machine, we should know the voltage of transformers, the normal single-stage vacuum oil purifier is only for the the transformers less than 35KV, double stages high vacuum oil purifier for more large-scale transmission voltage equipment, transformers and substation more than 110KV.
Following is introduction of double stages vacuum Transformer Oil Filtration Machine
1. Double stages high Vacuum Oil Purifier is higher than the national standard, a filter breakdown voltage can be increased by 35KV, reducing the general oil filter several times leading to the aging of oil hazards.
2. High vacuum, large pumping speed, pumping speed power ≥ 333L / s, to meet the installation or maintenance site on the transformer body vacuum needs, and at the same tie to complete the degassing of the Transformer Oil Filtration.
3. Nano-molecular material filter and three-dimensional three-dimensional flash, efficient removal of transformer oil in the water, gas and impurities, improve oil pressure strength and oil quality.
4. Automatic control, man-machine separation operations.
5. The use of VK micro-grams of technology, can effectively remove the dissolved water and other trace amounts of water.
6. can achieve more than 110KV power transmission equipment, vacuum oil, vacuum drying, vacuum purification.
◆ Vacuum Oil Purifier appearance Vacuum degassing tank, electric heater, condenser support steel frame and other equipment quality should be intact, no loose connection. Welding parts without welding tumor, burr, rust, the product surface using spray technology, the use of stainless steel bolts for connection, the surface should be bright and clean.
◆Heating system of Transformer Oil Filtration Machine
1) Heating surface heat load less than 1.0W / cm. In the heating process will not be due to overheating lead oil cracking and aging and other hazards.
2) The heating system is safe and reliable, with safety protection device, to prevent the heating system oil-free dry, heating system and vacuum system, oil system interlocking triple protection, to avoid excessive damage to oil temperature equipment.
3) The use of interval control, to avoid the oil temperature to set the temperature value of the contactor frequent start, the maximum extension of electrical life.
4) Optimized heating device design, effectively put an end to the production of harmful gases in the oil filtration process, the formation of safe and reliable heating system, the optimal pipeline design to ensure that no “dead zone”, and oil temperature can be 20 ~ 80 ℃ between the arbitrary regulation, constant temperature heating. At the same time, according to the climate, set up with automatic and manual heating options.
◆ Vacuum purification system
1) the basic requirements, manual car, no jamming phenomenon, the operation, the shaft seal is not oil, technical indicators to meet national standards;
2) The pump by precision machining means, using a unique way to ensure that the oil pump without leakage; even in the whole system at the limit of the vacuum pump oil is still normal to ensure that the machine performance and stability, improve oil treatment efficiency.
Vacuum separation system
Two-stage high efficiency Transformer Vacuum Oil Purifier adopts the vacuum negative pressure principle, the double-dimensional three-dimensional vacuum separator greatly increases the vacuum separation area, the oil mist in the vacuum separator through the film atomizer, spray device to atomization, The gasification process, oil molecules and water molecules are completely in the vacuum system, so that the water and gas in the oil to obtain sufficient vaporization separation time, can fully remove the water and gas.
◆ Condensation system
Unique media condensation system completely cool the oil separated from the water vapor to prevent water into the vacuum pump, resulting in vacuum pump oil emulsion fuel injection, to extend the life of the vacuum pump;
◆ Filters of Vacuum Oil Purifier
1) Using three step-by-step encryption filter system, the first filter and the second filter for the stainless steel, high filtration efficiency, long service life. Filtration accuracy of 50μm and 20μm,to filter out the oil in the larger impurities. And can be done according to customer requirements backwash design, do not have to remove the filter in the case of automatic washing, eliminating the need for a large number of manual cleaning work
2) fine filter using polymer polymerization variable pore size filter, filter fiber and pore size along the direction of oil flow gradually narrowed, layered filter different particle size impurities, greatly improving the ability to accept pollution and filtration accuracy, you can filter in addition to 1 to 5μm Impurities, filtered oil cleanliness to NSA6 level.
3) the configuration of the pressure alarm protection device (measuring the degree of contamination of the filter), the design protection pressure of 3 kg to ensure that the filter will not be damaged due to overpressure, reducing the use of cost to ensure that the filter system is safe.
1) High-quality industrial components to ensure continuous normal operation of the machine;
2) With overvoltage, over flow, overload protection device;
3) Vacuum pump, oil pump and heater Trinity protection design, to prevent the heater dry and pump idling.
4) The use of intelligent display temperature controller, which is characterized by high reliability, can set the upper and lower temperature limit to avoid the frequent start of the heater can extend the life of the appliance.
5) Control layout design easy to operate, the button design for the total power switch, vacuum pump start, stop, pump start, stop, heating start, stop, and each has a light display.
6) The unit has phase sequence, lack of protection function;
7) Electric control cabinet wiring with the standard trough neat, electric control cabinet outside the line using cable and wear iron back protection.
◆ Vacuum system
1) Vacuum pump selection with Sichuan Nanguang, rotary vane vacuum pump. (Note: optional imported Leybold vacuum pump)
2) Configure the pump outside the cooling device to reduce the operating temperature of the vacuum pump; extend the service life.
◆ Other instructions of Vacuum Oil Purifier
1) The inlet and outlet ports are made of anti-lubricating inverted taps, and the fittings are made of standard stainless steel fittings.
2) Oil flow part of the ball valve selection of 304 stainless steel ball valve.
3) Part of the whole connection with GB stainless steel bolts
4) The inlet and outlet piping design has a safety device to prevent the sudden shutdown after the oil back.
5) All the basic parts of the machine are phosphating treatment, internal paint 1032 anti-rust paint, not rust
6) Designed for mobile, base with rings, loading and unloading more convenient.
8) The surface of the machine using spray – to enhance the surface strength and hardness, can avoid such as paint machine scratches, bumps and loss of light;
9) The machine is strictly speaking, there is no wearing parts, because they will not bring no additional expenses.
10) The machine through the optimization of the design, so that the layout is more reasonable, especially easy to maintain, in the fault area for maintenance, replacement can be, without repairing pieces and dismantling pieces of pieces.
11) Easy operation, online filter oil, no one can run, maintenance interval long.
12) Shipped to the noise, running status by the light display.
