Borescope inspection

To view invisible areas, borescopes are optical tools without damaging items. There are some advantages of borescopes. The first one is the accuracy of measurement. For many industries, they require accurate capability to position while some need comparison measurement. Secondly, borescopes make inspection more consistent and efficient. Lastly, borescopes keep you connected with wired or wireless communications to PCs, computers, networks and other devices.
Generally, borescopes are composed of these components, including rigid or flexible working length, optical system, sources of light, and tools to view the image. As for application, borescopes are used in many industrial procedures but they are particularly used in gas turbine inspection. In other words, borescope Inspection is really essential to a gas turbine inspection. Operating at much higher temperatures than other turbines, such as steam turbines, the procedure of gas turbines can be very dangerous. The reason why borescopes are crucial to the inspection of gas turbines is that borescopes help these gas turbines to be inspected in a safe way. By doing so, these inspections with borescopes can effectively prevent accidents from happening because of astounding heat from gas turbines. At the same time, they can identify unknown problems inside the machines as well. As a result, they help reduce the cost of repairs and unexpected workplace injury. 

What is a borescope camera?

When it comes to borescope cameras, there are some common types to tell, including rigid borescopes, flexible borescopes (also known as fiberscope cameras) and semi-flexible borescopes. For rigid borescopes, they are commonly utilized in areas that have direct access because they lack flexibility. As a result, compared to the other two borescopes, the cost of rigid borescopes are the most affordable ones.However, they are usually used for rigid type because the photos out of rigid borescopes are clear.  As for flexible borescopes, even though they can’t provide the same quality photos as rigid borescopes, they are helpful devices to reach objects that are hard to reach. Hence, flexible borescopes cost the most among the three types. Nevertheless, flexible borescopes are not common in some areas that require high image quality and high cost. Lastly, it’s semi-flexible borescopes. They do not cost as high as flexible borescopes and they offer better quality pictures than flexible borescopes. Usually, semi-flexible can be used to operate the minimal manipulation for inspection in small tubes. All in all, it’s important to know what kind of borescopes you truly need. What kind of borescope and size of borescope best suit your needs? What is the most suitable length of the borescope for you? They are all the essential questions you should ask yourself while making your choice to purchase.

Types of borescopes

• Rigid Borescopes: Rigid borescopes transmit apparent and high-quality images. Owing to lack of flexibility and limited movement, rigid borescopes are more cost-efficient and are commonly utilized in areas where entry paths are straight.
• Flexible Borescopes: Different from rigid borescopes, flexible borescopes are more advantageous if the areas are inaccessible and challenging. Besides, flexible borescopes cost more than rigid borescopes. Inspectors commonly use flexible borescopes for versatility and efficiency.
• Semi-rigid Borescopes: Semi-rigid Borescopes are an improvement from rigid borescopes. Semi-rigid borescopes share some similarities with flexible borescopes. For instance, semi-rigid borescopes allow users to conduct the minimal manipulation for inspection in small tubes.
• Micro Borescopes: Micro Borescopes are aimed to inspect extremely narrow areas. Equipped with semi flexible probes, micro borescopes are available to inspect various curves and corners. In addition, due to probe fields being easier for users to replace, it decreases the downtime and improves efficiency.

Different types of borescopes cater for different situations. Each OME-TOP borescope will have its own specific inspection probe for use. You can learn more instructions and specifications from different product pages based on your needs.

Borescope technology

In order to improve more precise monitoring and more stable maintenance, the technology of borescopes keeps advancing. By doing so, users can effectively lower repair costs during unscheduled downtime. 
The first one is Complementary Metal Oxide Semiconductors (CMOS). CMOS becomes more and more affordable with a few hundred dollars to get . Historically, CCD image sensors are the common one but now because of advanced technology, CMOS increases performance with lower cost and makes it competitive to make changes to systems with older CCD image sensors. The second one is the upgrade of measurement. In recent years, borescopes have been capable of measuring smaller defects. Hence, in terms of the need of quantifying, it’s a great step, especially for aircraft turbines because they can be kept in a longer time than they could in the past. The last one is the relay lens system. And thanks to Gradient Lens Corporation, it made the relay lens system(the core of borescope design) even easier and less costly. More interestingly, dual-camera borescopes have been a great innovation recently. There are two cameras on one probe. In general, one camera is front view and 0 degree while the other one is side view and 90 degree. Both of the cameras have lighting separately and users can switch the view directions with merely one button.

How to use a borescope?

Borescopes are regularly used for industrial systems and equipment that require the need of non-destructive testing. Using a borescope makes it possible for you to inspect the narrow and cramped areas. Since a borescope can provide an easier way to see into internal working, there are several kinds of applications, including the inspection of aircraft, motors, and industrial machinery.

Applications of Borescopes – Aviation and Aircraft

The borescope plays an important role in the inspection of aircraft and airframes. Regular inspection of turbine blades is extremely fundamental to aircraft. Borescopes can be used to capture the images of internal machinery, so any possible FOD (foreign object damage), wear and damage can be observed on time. Therefore, borescopes help maintain the durability and reliability of the aircraft gas turbine, repair the wear of components, and examine the contaminated fluids and leaks.
Below are some areas of borescope Inspection for aviation:

• Combustion Chamber:Burner cans are properly tested for any cracks. Fuel nozzles, louvers and other parts are tested for unnecessary coking, damaging, cracking and distortion as well.
• Compressor: Compressor blades along with guide vanes are tested for foreign object damage (FOD) and corrosion.
• Turbine Section:The highest heat levels are experienced in the first stage turbine; hence guide vanes and stationary nozzles can be burnt, cracked, eroded and damaged. Second stage blades are also subjected to rivet cracking and shifting.

Aviation professionals trust the JKVS-60034 Articulating Video Borescopes from OME-TOP for the remote visual inspection needs. Non-destructive maintenance inspections guarantee that aircraft's components are still fully functional while allowing the plane to work inside their busy flight schedules with minimal delays.

Applications of Borescopes – Heat Exchanger Inspection

Borescope can assist the inspection of heat exchangers. Heat exchangers can be adversely affected by loose debris, corrosion, pitting, leakage, etc. Reliable operation of systems using heat exchangers mainly depends on the health of components. When equipment wear occurs, it needs to be addressed right away. Otherwise, minimal damage may decrease the efficiency of functioning. JKVS-60054 / JFVS-60054 / CT5-60054 Series articulating borescope allows you to correctly inspect systems.

Utilizing borescopes can help identify any cracks and leaks before catastrophic system failure. If the wear of heat exchangers is caught on time, it is completely fixable. Periodic equipment inspection with a borescope can help repair any cracking and reduce the cost of changing a new machine.

Application of Video Borescope – The Automotive Industry of The New Energy

Since environmental issues are gaining more attention nowadays, the traditional automobile industry has been replaced by environmentally friendly vehicles recently. Industrial video borescopes (or electronic video endoscopes) can be used to observe the interior of equipment or components without disassembly or damage. Hence, industrial video broescopes are widely used in the internal inspection process of traditional automobile engines, tubes, castings and other various parts.

The reason why industrial video borescopes are also called electronic video endoscopes is that electronic video endoscopes are variants of industrial level endoscopes. Moreover, in the field of manufacturing and maintenance of new fuel-efficient vehicles, video scopes are gradually being used in various applications, such as battery detection.

To be more specific, the major components of the battery are the management system, thermal management system, evaporator, ventilator, air duct, etc. The video borescopes can be applied to the detection of battery packs of new energy vehicles, and the probes can enter the inside of the battery pack for effective surface observation, which is more convenient for batch inspection and quality management. In the production and manufacture for new energy vehicles, a large number of procedures are often produced by die-casting process. Thanks to the video borescopes, loosening of the surface, cracks, sand, air bubbles and other defects caused by the casting process can also be efficient. On the whole, an appropriate tool in the service process is also an important test equipment for quality control of new fuel-efficient vehicles.
As stated above, the applications of borescopes are numerous. You are welcome to contact OME-TOP if you need more information.
