Product Description

KVPD-series Vapor Phase Drying Equipment

　　Kerosene and gas drying equipment (VPD) is mainly used for **0kV and above high pressure, high-capacity transformers, transformers and other drying of the body.

　　◎ Work

The basic principle of kerosene vapor, is the use of kerosene heat in vacuum evaporation, a high temperature of the kerosene vapor at lower temperatures encountered in the vacuum tank of the workpiece and condensation, condensation latent heat release (about **6.6kJ/kg) and thus the body for heating. Condensation of kerosene is collected through the kerosene delivery system re-transported to the evaporator, re-heating evaporation, and so many times, the workpiece temperature continues to rise, which the water has been evaporated into water vapor, is pumped vacuum system, and ultimately achieve thorough drying purposes.

　　◎ kerosene vapor phase drying equipment and technology

● preparation phase:
The product in a vacuum in the vacuum tank, the pressure reduced to **0Pa or less. While the vacuum tank body heat insulation, pre-evaporator heating of kerosene, the kerosene vapor evaporator outlet temperature from *8 ℃ gradually warming up to **0 ℃, kerosene vapor from the liquid state into a state of diffusion in a vacuum tank, full and hot products the exchange.
● heating stage:
At this point only a vacuum system to maintain the pump station work, the vacuum tank and vacuum condensate collection tank to maintain the vacuum required in the process. Kerosene steam transformer for heat exchange, condensed flow buffer tank, and then return to the evaporator to form a loop. As the temperature continues to rise, kerosene vapor, evaporation of water vapor in the insulating material so that the vacuum tank pressure gradually increased, this time by maintaining a mixture of gas pumps will be able to get the condensate recovery system for condensation, separation. Kerosene and liquid condensate separation and then enter the evaporator, the process continues until the body temperature step-down process requirements to enter stage.
● step-down phase (or called the low vacuum stage):
Stop delivery of kerosene to the evaporator, a vacuum tank continued to be a mixture of gases out of the vacuum tank, the insulation material left in the re-evaporation of kerosene for condensate recovery. According to the product of different capacity and voltage levels, blood pressure stage and intermediate stage can be alternately heated several times to make the best
