PREACUTION TO BE TAKEN DURING MAINTENANCE:-

The crane must be moved to a location with at least interface with other crane/equipment or operator

All the controllers must be off position LOTO to be applied

Non Destructive Test (NDT)– Procedure

Image
  NDE test: - NDE Inspection is used to detect any surface-connected discontinuities such as cracks from fatigue, quenching, and grinding, as well as fractures in joints. Material required for NDE test: 1)     Penetrant (Red color) 2)     Cleaner 3)     Developer (White color) Penetrant: Penetrants are classified into two types. 1. Fluorescent 2.Non- Fluorescent. Fluorescent penetrants contain two or more dyes that fluoresce when excited by ultraviolet (UV-A) radiation. Non-Fluorescent penetrate inspection is performed in a darkened environment. NDE test Inspection steps:-   1.       PRE-CLEANING 2.       APPLICATION OF PENETRANT 3.       EXCESS PENETRANT REMOVAL 4.       APPLICATION OF DEVELOPER 1.        PRE-CLEANING :- The test surface is cleaned to remove any dirt, paint, o...

MAINTENANCE FOR TURBINE BLADE CLEANING METHODS

Image
  Purpose of blade cleaning :-   Wind turbines blade surface, naturally accumulate dust and other forms of detritus. Often with wind turbines, this takes the form of grease or hydraulic oil from motors and other parts of the turbine. This prove to be unsightly and can cause dirt to accumulate at an accelerated place. The main purpose of blade cleaning is to eliminate dust and insect buildup, which otherwise deforms the shape of the airfoil and degrades performance. Blade cleaning is especially important in arid climates where there is not sufficient rainfall to help keep the blades clean. Types of Blade cleaning Methods: - 1.      Manually cleaning Method (Rope Access). 2.      Cleaning blade with Helicopter 3.      Blade cleaning with Robot mechanism 4.      Wind turbine blade cleaning with truck platforms. 5.      Blade cleaning with flying DRONE System. 6....
