Automatic vacuum pumping unit HZKC-500

The HZKC-50 series equipment is used to evacuate the gas from the transformer, so that the iron core, coil, and insulating materials inside the transformer are completely exposed to a high-vacuum environment. In this high-vacuum environment, the moisture absorbed by the iron core, coil, and insulating materials evaporates into the air and is then discharged by the vacuum pump. This process achieves the function of drying the transformer. Product technical parameters Operating noise: ≤75dB(A) Interface diameter: DN40 Ambient temperature: -10～50℃ Working power supply: 480V 60Hz three-phase three-wire Total power: 4.5kw Dimensions: 1300×950×1550mm Equipment weight: 520Kg Continuous working time: ≥2000 hours Average trouble-free working time: ≥50000 hours Main features of the product The pumping speed is fast. The vacuum pump and roots pump can be started simultaneously, increasing the efficiency by 40%. The equipment automatically adjusts the pressure difference between the inlet and outlet of the Roots pump and vacuum pump to ensure that the exhaust port of the Roots pump is always at its highest pressure state. This also ensures that the gas at the inlet of the vacuum pump always maintains the highest compression ratio. The exhaust port of the Roots pump is equipped with a liquid cooling device, which not only prevents the Roots pump from overheating but also reduces the volume of the compressed gas exiting the Roots pump. Other Roots vacuum pumps can only be started when the vacuum degree is reduced to 1000–2000 Pa. High vacuum. A two-stage or three-stage vacuum pump is used.
