The 1st step of the transformer oil
purifier operation is to know the functions of the main parts of the oil
purifier.
We would like to list the following; it is the
ZYD-II-50 machine, as the example.
Main Spare Parts Introduction
â— Primary
filter: Remove the big impurities which are biggest than 30μ, it can avoid the
jam in each oil pipe and reduce the abrasion of oil pump. It is stainless
Steel, washable.
â— Secondary filter and fine filter: UK APUREDA
filter, the precision is 1μ
â— Condensation: The
water in heated oil forms vapor in vacuum tank, and then the vapor forms liquid
water due the low temperature in condensation. The condensation not only
reduces the temperature of vacuum pump, but also it also reduces the frequency
of changing vacuum pump oil so that it can enlarge the lifetime of vacuum pump.
â— Vacuum pump and Roots
pump: Providing vacuum source
â— Oil pump: Transfer the oil
which is exhausted the gas to outside.
â— Heater: Heat oil
â— Vacuum sensor and pressure
sensor: Detects vacuum value and pressure value
â— Double-infrared level sensor: Connect the oil
pump and electromagnetic valve to control oil pump and electromagnetic valve,
keep inlet and outlet oil balance.
