Industrial endoscope guide inflexible how to solve?

    In the inspection process of industrial endoscopes, the implementation process is the result of several functional parts working together, among them, imaging clarity determines whether defects can be found, and the guidance function affects the speed of defect finding. Probe guidance is critical to inspection efficiency, but in use sometimes feel that the probe guidance becomes insensitive and inflexible, this article introduces you to a solution to the inflexibility of the industrial video endoscope probe guidance.    First of all, let's look at the principle of guidance. The inspector manipulates the guide lever on the industrial endoscope, the front of the probe guide joint can achieve different directions of bending, so as to achieve the probe guide, this long-distance operation is how the "remote control"? The important thing is the guiding wire that connects the handheld to the guiding joint, for example, the tungsten wire used by JEET industrial endoscopes, which has better ductility. The control of the guiding joystick makes a difference in how tight or loose the wire is, thus pulling the guiding serpentine in the appropriate direction.    The guiding wire is usually encapsulated in the guiding channel of the probe wire, usually only a few millimeters in diameter, with other cables in between, so the space of the guiding channel is very compact, and there is also a tighter contact between the wires, and a tighter contact between the wires, in order to reduce friction during the guiding operation and make the guiding guide smoother.    Here, the smart you may have guessed the reason for the inflexible probe guide. It is true that the use of solid toner and other lubricating powder is to reduce the guiding friction, at first the lubricating powder is uniformly distributed, but over time, long-term use will cause toner accumulation, indirectly leading to the guide angle decay, the situation described in the opening paragraph. In this case, there is no need to panic, eliminate the cause of the problem can be, jitter probe is an effective solution, can make the lubricating powder redistribution, guide performance and then restore.    The specific instructions for shaking the probe are as follows: Generally, two people need to work together, one holding the bottom of the guiding joint, the other holding the root of the probe and gently swinging it from side to side several times. Please note that do not squeeze the guiding joint, because the guiding joint is relatively soft and artificial force to bend it may reduce the guiding life of the device.    I believe you have mastered the solution to the inflexibility of the industrial endoscope guide head. Generally speaking, in the daily equipment inspection, and in the inspection process, if a similar problem is found during the inspection process, you can try to solve the problem with the solution of jittering the probe. If there is no improvement, we recommend that you check the probe line as soon as possible to see if there is extrusion deformation or damage, and contact JEET industrial endoscope for maintenance.

What are the advantages of industrial video endoscopes?

Industrial video endoscopes are increasinglyapplied in visual inspection. What are the advantages of industrial videoendoscopes, compared with traditional endoscopes? 1)   Higher display resolution and better imagequality. With high-quality optic lens, videoscope has a great improvement indisplay resolution and image clarity, compared to traditional endoscopes.2)   More compatible with different inspectedtargets. According to field of view, viewing direction and distance, videoscopecan be customized with sideview, front view lens, far focus or near focusviewing distance, which can be adapted to different inspecting requirements.3)   360° flexible articulating operation. Videoscopes are equipped with360° articulating probe. The bending angle is more than 150° in each direction.The bending angle of JEET videoscope can even reach to 190°. It is easy to passthrough the curved part of the inspected pipeline.4)   Joystick control articulation. The probe articulation is controlledby joystick. Users can easily operate it by only a finger.5)   The durability of the insert tube is greatly improved. Thetraditional stainless-steel tube has been replaced by tungsten-braided tube,which can greatly enhance the wear resistance of the videoscope tube anddecrease repair rate. 

How many levels of industrial endoscope waterproofing are there and how are they graded?

Industrial borescope waterproof grade reflects its ability to prevent moisture and dust, especially for industrial borescope outdoor operations or police borescope criminal investigation operations, inevitably in the high humidity or dusty sand in a harsh environment, the sealing and waterproof ability of the borescope is essential to ensure the safe operation and life of the instrument.Protection level using the International Electrotechnical Commission (IEC) recommended IP × × grade standard. In the rating standard, "××" is a two-digit number, the first indicating the level of protection against solids and the second indicating the level of protection against liquids. There are 7 grades of solid protection, which are indicated by 0-6 respectively; there are 9 grades of liquid protection, which are indicated by 0-8 respectively.Dust protection level0 : No protection1 : Protection against large solids2 :Protection against medium-sized solids3 :Protection against small solids4 :Protection from solids larger than 1mm5 : Prevents the accumulation of harmful dust6 : Completely prevents dust from enteringWaterproof grade0 : No protection1 : No effect of water drops into the housing2 : No effect of water dripping onto the housing when the housing is tilted to 15 degrees3 : No effect of water or rainwater from 60 degree corners onto the housing4: liquid from any direction to splash into the shell no harm impact5:No effect of low pressure spraying from any angle6 :No effect of high-pressure spraying water7: can be submerged in a short period of time (within 1m water depth, within half an hour)8: in a certain pressure for a long time submerged in waterJEET full range of borescope pipeline can support IP67 grade, the body can support IP65 grade, to meet different customer needs, while the special process to provide customers with customized IP68 dustproof and waterproof industrial borescope.

What should be paid attention to when using industrial endoscope?

Industrial endoscopes are widely used in many fields, like the inspection of special equipment, aviation, pipelines, pressure vessels, automotive manufacturing, power and other industrial areas. During real application, it will face different testing environment. What should be paid attention to when using it?1) Prohibit the use of industrial endoscope to observe the body or the animal's body;2)Do not use videoscope to inspect equipment in action; 3) Do not use or store the videoscope on explosive, strong electromagnetic field or with combustible gas,otherwise it may cause fire or explosion;4) Do not use it to check objects with current carrying, so as to avoid the occurrence ofelectric shock;5) Do not watch the LEDlight source at the end of the lens straightly, avoiding the effect of stronglight on the visual acuity;6) Never excessivebending, stretching, twisting, rolling cable, otherwise it may cause cabledisconnect, a fire or electric shock accident;7) If there is abnormal inthe angle adjustment operation, stop the current operation, and turn off. Thencontact the supplier;8) Keep the insert tubeaway from any liquid, except water, salty water or oil;9) When finish using,please clean the tip of the videoscope probe in time, to prevent corrosion.

How to select suitable videoscope?

Visual Testing (VT) has become a common testing method in NDT. As an important tool of VT, industrial videoscope has been widely used in various fields such as automotive manufacturing, aerospace, petrochemical, pharmaceutical machinery, electric power, etc. It has become a necessary method of quality control.With the wide application and increasing demands of industrial videoscopes, what problems should we pay attention to when purchasing videoscopes? In the face of various brands, different price of products in the market, how should we identify and seek reliable products that meet our needs?1. Demand positioning: at present, industrial endoscopes are mainly electronic videoscopes. The prices range on the market is from several hundred (rigid borescope or USB borescope) to thousands of dollars (flexible videoscope or articulating videoscope). During the purchasing, we need to consider our inspection needs and budget to select the suitable products.2. Three main factors determining the price of videoscope: resolution, diameter and length. The higher the camera pixels, the higher product price. The smaller probe diameter and the longer the tube, the more expensive the product.3. Articulating control method: It commonly has two methods to control the probe articulation, motor-driven articulation or mechanical-control articulation. There is no difference in function that both ways can realize 360° all-way articulation. Motor-driven articulation is labor saving, automatic reset after probe bending with short delay. Mechanical-control articulation is more flexible and easy control, reset with no delay. In short, these two methods are not much different. People can select according to their own preference.
