Turbine oil pipeline pure water cleaning system

Abstract

The invention discloses a pure water cleaning system for steam turbine oil pipeline, comprising a pure water cleaning liquid preparation subsystem, a large flow cleaning subsystem, a quality purification subsystem, a cleaning control subsystem, a high pressure cleaning subsystem and a compressed air purge subsystem ; The pure water cleaning liquid preparation subsystem, the large flow cleaning subsystem, the quality purification subsystem are connected with the cleaning control subsystem, and the information collection, transmission and adjustment are carried out through the cleaning control subsystem; the high pressure cleaning subsystem and the large flow cleaning subsystem The connection and functions complement each other; the compressed air flushing subsystem is connected with the cleaning control subsystem. The invention realizes the patterned, programmed and intelligentized management of the pure water cleaning process, can efficiently, quickly, safely and thoroughly clean the steam turbine oil pipeline system, achieves the purpose of high cleaning and surface protection, and has significant economic value and social benefit.

Description

technical field [0001] The invention relates to the field of oil pipeline cleaning, in particular to a steam turbine oil pipeline cleaning system. Background technique [0002] The impurities existing in the steam turbine generator oil pipeline system of the power plant generally come from: 1. Impurities retained in the manufacturing and installation process, such as welding slag, rust, iron filings, paint skin, fibers, etc.; 2. When the system is running at a slight negative pressure Pollutants invaded from outside, such as dust and sediment; 3. Glue, carbon deposits, etc. produced by the long-term high temperature and high pressure operation of lubricating oil; 4. Impurities and garbage brought in by the system during maintenance or oil replenishment; 5. System coating exfoliation and corrosion products on metal surfaces, such as iron oxide and iron sulfide. [0003] The above impurities are intertwined to form sludge, oil pollution, etc., which adhere to the inner wall o...
