ZLYC Series Efficient Vacuum Oil Purifier for Transformer Oil and Hydraulic Oil Treatment

Product Overview

Industrial Oil Purification Equipment covers vacuum‑based oil regeneration devices, and ZLYC series efficient vacuum oil purifier is specially developed for removing moisture, gas and solid particles from insulating oil and hydraulic oil. By utilizing different boiling‑point characteristics between water and oil under vacuum environment, this equipment completes dehydration, degassing and multi‑stage particle filtration synchronously. It is widely adopted in power industry for transformer oil maintenance and hydraulic‑station oil regeneration.

Application Industries & Working Conditions

ZLYC vacuum oil purifier mainly serves thermal power plant, nuclear power station and sub‑station transformer insulating‑oil maintenance work. It is also applied for hydraulic‑lubrication oil purification in metallurgy, petrochemical and heavy machinery manufacturing. When transformer oil absorbs moisture during long‑term running, dielectric strength drops sharply; ZLYC equipment removes dissolved water and air to restore insulation performance. It can run for batch‑mode offline oil‑treatment or connect with oil tank for cyclic purification. hydraulic oil filter machine provides complementary mobile purification solution for small‑volume working‑site.

Core Product Advantages

Multi‑grade composite filtration system realizes step‑by‑step impurity interception, from large‑size particle to fine micron‑level contaminants. High‑efficiency vacuum chamber removes both free water and dissolved water inside oil medium, meanwhile separating dissolved air which may cause oil oxidation. Modularized structural layout makes on‑site inspection and component replacement convenient. Complete protection modules prevent over‑temperature and overload during long‑time operation. Oil Filtration Machine series follows unified industrial‑grade production standard.

FAQ

Q1：What is the main difference between vacuum oil purifier and coalescence‑dehydration oil purifier?
A1：ZLYC vacuum purifier works under vacuum environment, good at removing dissolved water and dissolved gas inside insulating oil; coalescence‑dehydration unit is more suitable for large‑quantity free‑water and emulsified‑water separation for hydraulic lubricant.

Q2：Can ZLYC purifier process transformer oil on‑site without oil transportation?
A2：Yes. The whole set is skid‑mounted movable structure, can be transported to substation site and perform circulating purification for transformer oil on location.

Q3：What residual water index can ZLYC‑series achieve after processing?
A3：Under normal working condition, treated oil residual water content can reach 5‑30 ppm, which satisfies most power‑station insulating‑oil maintenance requirement.

Q4：How about daily maintenance items for ZLYC vacuum oil purifier?
A4：Check vacuum pump oil level; replace multi‑stage filter‑elements according to pressure‑difference alarm; inspect pipeline sealing condition; clean vacuum tank inner sediment periodically.

Q5：Can we adjust processing flow rate for special‑capacity oil‑tank?
A5：Custom‑tailored flow‑rate and dimension solution can be provided. Please offer oil‑tank volume, target water‑content and site environment parameters for our technical assessment.
