Borescope empowers technicians to visually investigate the turbine’s inner pathways. The internal components include impeller blades, rotor, and gas path. These parts are extremely hard to reach directly. You need to disassemble it to check the flaws.
Borescope helps to thoroughly inspect the turbine without any need to separate the components. It helps to detect damaged or deteriorated gears and bearing, foreign object debris, excessive worn out surface, and other problems that can cause sudden outages.
Choosing the correct borescope camera can help your business in meeting schedules as well as maintaining contracts, and ISO certifications. A wrong purchase decision can be a waste of investment because the system will sit ideally in the corner as it will not work well for your specific inspection environment. On usaborescope.com, you will come across the following kinds of borescopes.
Rigid borescope – It allows straight path inspection. The visuals are possible through an attached ocular.
Semi-rigid borescope – It is just like a rigid borescope but has a bendable tip.
Videoscope – Camera is housed in the insertion probe, which is tiny and easily maneuvers in tight spaces. Visual inspection is through a remote screen.
Steam or gas turbine equipment directly affects the production and financial aspects of the industry. Therefore, it is necessary to get regular inspection of the equipment to reduce potential downtime. When choosing an appropriate borescope, there are a few factors you need to consider.
Diameter & length
Large diameter means borescope will fail to navigate bends and get stuck in the turbine. The radius of turns in the turbine will help to decide the borescope’s diameter and length. Actually, short borescopes are more accurate than long ones.
While investigating the dark spaces within the turbine, there is a need for brightness. For illumination, there is a glass fiber, which delivers light from external sources. The brightness depends on the material, so for efficiency opts for a borescope that transmits more light and produces great image quality.
The view angle differs. It depends on the area of inspection within the turbines. A turbine inspection needs a 360-degree view of interiors, so a videoscope is recommended. Steam turbine testing needs search movements within the turbine, so articulating borescope is great.
It captures HD images. You can even make fine adjustments in borescope positioning during the inspection. Articulating borescope penetrates tight cavities with ease, which rigid borescope cannot.
If your work contains operating hundreds of feet below the ground, you don’t need a large, heavy, and unwieldy equipment. So, consider its weight and portability.
Borescope has to be water-resistant and capable of handling extreme temperatures. Borescope damage repairs and replacements are costly, so durability is a major factor.
Operators need more time in equipment training or borescope tips need to be changed often to accommodate the different focal lengths. Check the holdups in the equipment because the right one will hardly cause any downtime.
Battery life, ease of use, service cost, warranties, and customer support are other factors to look into before you make a borescope buying decision.
