Method for treating and maintaining equipment damaged by water

Abstract

The invention relates to a method for treating and maintaining equipment damaged by water, which comprises the following steps of: 1, pretreatment: detaching a product polluted by water pollution, andcleaning the product; 2, detection before electrification of the equipment polluted by water, and detecting whether each electric control part of the cleaned equipment is short-circuited or not, whether an equipment cable is poor in insulation or not, and whether air leakage, oil leakage and water leakage phenomena exist in an air path and an oil-water path or not; 3, detection after electrification of the equipment: based on the result detected in the step 2, performing energy supply and detecting the on-off state on the premise of meeting the basic energy supply of the equipment; and step 4, equipment maintenance: maintaining or replacing the damaged device after the detection in the step 3. The purpose of reducing the cost can be achieved.

Description

technical field [0001] The invention relates to a treatment and maintenance method before equipment is damaged by water. Background technique [0002] The damage factors of equipment in catastrophic accidents include mechanical damage, thermal damage, electrical damage, pollution and so on. Among them, pollution is the part with the most salvage value and the most restoration possibility. Pollution is mainly divided into: liquid pollution (water, acid-base liquid, etc.) and solid pollution (smoke, sediment, etc.). [0003] The main impacts of automation equipment by water shower or flooding are as follows: [0004] The equipment control part will cause internal short circuit to related electronic components (such as: PLC, frequency converter, man-machine interface, industrial computer, single chip microcomputer, etc.) The board itself has a battery, which will also cause internal long-term continuous discharge and electrical corrosion, resulting in the possibility of dama...

Problems solved by technology

[0004] The equipment control part will cause internal short circuit to relevant electronic components (such as: PLC, frequency converter, man-machine interface, industrial computer, single-chip microcomputer, etc.) The board itself has a battery, which will also cause internal long-term continuous discharge and electrical corrosion, resulting in the possibility of damage to related electronic components;

[0005] The mechanism part of the equipment will cause surface corrosion, oxidation and rust to related mechanism components (such as: iron, aluminum sheet metal parts, bearings, screw rods, etc.) after being watered or flooded, affecting the accuracy of the equipment, jamming and other problems

For general metal parts (such as metal contacts and terminals of electrical equipment, etc., taking steel parts as an example), the early rust (corrosion spots, etc.) is mainly ferric oxide, and its color is brownish red (dissolved in water is reddish ), because the rust is spongy (the volume of rust generated by iron can expand eight to ten times), and the rust is a brittle and porous material, which is easier to absorb moisture, corrosive gases and oxygen in the air (such as the principle of activated carbon), resulting in further Corrosion and oxidation, that is, accelerated corrosion, the formation of ferric oxide, which is dark black, and will form obvious rust pits or rust spots on the iron surface, that is, after serious rust oxidation, the rust pits and rust spots cannot be removed by rust removal methods dealt with and resolved
