Our Advantages

1. The latest development of intelligent full digital motherboard, debugging only need to set and calibrate parameters on the touch screen, truly digitized, do not need to adjust the potentiometer on the motherboard, making debugging easier. During operation you can set the screen power, you can also use the potentiometer to adjust the power, this function conversion can be achieved on the screen through the software setting. Make the device run more stable.
2. Providing with High cost performance and quality of imported equipment, with the domestic mid-end price, with a perfect protection system.
3. The water pressure data of the power supply and furnace body are collected and stored in the PLC system in real time, and the alarm is set on the touch screen.
4. The power supply part of the reactor, rectifier, inverter, filter, resonance and other parts of the backwater are installed temperature detection, the problem of the waterway branch has a light-emitting diode indication, and in the touch screen and mobile phone real-time indication of the fault appears in that part, the serious fault directly causes the power to stop running.
5. Detect the water level in the closed water cooling system, and immediately stop the alarm when it is lower than the set position.
6. The power, DC current, IF voltage and if current of each set of equipment are protected in real time. If the set value is exceeded, it will be automatically adjusted immediately, and the protection will be stopped in time.
7. The inverter signal is transmitted by optical fiber: compared with the traditional electrical signal transmission, it is more resistant to electromagnetic interference, and is not affected by mid-frequency electromagnetic interference, so that the equipment can be operated stably.
8. The leakage discharge or injection protection system of the equipment collects the leakage current data through PLC, and quickly judges the furnace leakage alarm and stops according to the leakage current, so as to realize the protection before the furnace body leakage. And can query the previous leakage current data to judge the condition of the furnace
9. he equipment circuit breaker adopts intelligent circuit breaker: it has sensitive overload trip protection and short circuit instantaneous trip protection function than the mechanical circuit breaker, and can quickly trip protection in the short circuit state at the back end to prevent the transformer from short circuit overload.
10. The reactor uses an empty core reactor and uses epoxy resin for pouring, which makes the sound quieter during operation. Conductive copper pipe adopts thick wall, large inner diameter copper pipe, lower heat, not easy to scale, long service life.
11. The 81 type water jacket is adopted, which has large size, large conductive cross section, low heat output, and larger water cavity of the water jacket, which is less prone to fouling and blockage, and has better cooling effect on the thyristor.
12. Inverter thyristor adopts KF asymmetric thyristor, because of the different structure of the PN junction inside the thyristor, the positive and negative voltage withstand values of the thyristor are also different, and the reverse PN junction is therefore lower in heat, so compared with the previous KK thyristor loss, higher temperature resistance characteristics, and longer life. However, because of the PN structure, KF thyristors can only be used in series inverter equipment.
13. In series resonant inverter one power supply tows multi furnaces system, the total power can be freely distributed, multiple devices do not affect each other, and the total power does not exceed the total transformer load.
14. The equipment realizes constant power output according to the set power, which has more advantages for long-term insulation, can ensure that the set insulation power is constant, improve the utilization rate of the transformer, and save the loss of the basic electricity cost for the user.
15. All kinds of equipment information is stored in the memory, and the data can be tested to the computer, which is easy to query and analyze the fault information in operation, and improve the stability of the use of equipment.
16. The whole water cooling system uses stainless steel pipes and high-quality hose, and the water quality is maintained well, avoiding the ducking of each branch water pipe, reducing the failure rate and increasing the stability of the equipment.
17. Open frame furnace body, inspection, maintenance more convenient and rapid
18. The 0.3mm oriented silicon steel sheet is used to reduce the loss of the magnetic yoke and save power consumption. The induction ring has been simulated and tested for many times, and the equipment configuration is more reasonable. The anaerobic copper tube with a wall thickness of 8mm has low impedance of the induction ring and low loss, which is an important energy-saving measure.
19. The induction ring adopts porcelain insulation treatment, and the coil protection cement is poured inside and outside, which further improves the insulation of the coil and reduces the failure of the coil ignition caused by humid working condition.
20. The oil cylinder is installed with an anti-pipe burst valve. Once the oil pipe bursts, the oil cylinder is in a locked state or slowly falling to prevent malignant accidents. The hydraulic station adopts fireproof glycol based grease to prevent fire accident.
21. The quality of our products is stable and reliable, in order to provide customers with more satisfaction, we guarantee warranty period within 2 years.
