Portable chip detecting device for pipe

The present invention relates to a portable pipe chip inspection mechanism, in order to be able to easily check whether the iron chip contained in the fluid flowing in the pipe, the upper cap is installed with a clip, and the head portion that the upper cap is fitted with, One end is coupled to the head part, and the opposite end part is provided with a chip detecting magnet for adsorbing and collecting chips in the fluid inside the pipe, and the tip including the chip detecting magnet is installed through a chip inspection hole installed in the pipe. And an inner tube having a predetermined length to be inserted into the oil in the pipe, and a tubular body portion detachably coupled to the inner tube while the chip detecting magnet and the inner tube are inserted inward. Portable plumbing chip check mechanism.

In general, in a bearing mechanism for supporting a rotating body or a mechanical component in which rapid friction occurs between the driving parts during driving, frictional heat and abrasion may cause damage to the bearing mechanism or mechanical components, and may be very fatal to the entire machinery including them. have.

Therefore, in the above-described machinery, it is essential to minimize the occurrence of frictional heat and abrasion by appropriately supplying the oil mainly for cooling and lubrication to the friction part. For this purpose, oil is supplied to the machinery that requires continuous operation for a long time. It is common to have a separate oil supply system to circulate.

The oil supply system basically includes an oil tank for storing oil and a pump means for sucking oil from the oil tank and delivering the oil to the friction part. The oil tank, the pump means and the friction part are oils such as pipes, tubes or hoses. It is connected to a passage (or pipe), and the oil passage is provided with a valve means for selectively controlling the flow of oil.

On the other hand, the oil supplied from the oil tank to the friction portion through the oil passage is drained and then stored in the oil tank for resupply. The oil circulated in this way may include wear and tear off from the friction portion. As a result, special care is required in operating the machinery.

That is, in the case of a mechanical device including a bearing, in the oil passage of the oil supply system for cooling and lubricating the bearing, there is a wear content of iron (Fe) component, ie, chips (hereinafter, referred to as chips), which are separated from the bearing. Occasionally, the chip is re-supplied to the bearing with oil, which can lead to a reduction in the life of the bearing as well as the life of the whole machine, which can be a cause of large accidents.

Therefore, in order to prevent the above problems and risks, it is most important to know in advance whether chips exist in oil.

In the past, as a countermeasure against the above problems and risks, it was only to periodically take an oil sample to inspect the presence of chips, or to take measures after diagnosing vibration and heat generation conditions in the friction part.

However, the chip presence inspection carried out as described above is not only impossible to determine in advance the presence or absence of the chip in the oil in advance, there is a problem that the work is cumbersome since the oil sample must be inspected separately.

In addition, the method of diagnosing the vibration and heat generation state of the friction part cannot be a fundamental countermeasure for detecting chips in oil in advance, and it is not easy to access because the friction part is a high temperature area due to the driving characteristics. As well as the need for expensive measuring equipment was a problem.

On the other hand, as a countermeasure for preventing the iron chips in the oil to be introduced into the friction portion, a number of filtration devices using a magnetic filter is known, but these filtration devices are complicated in configuration, and the complex filtering structure of the magnetic filter Because of the high manufacturing costs had a disadvantage.

In addition, in the filtration device employing the magnetic filter, the filter replacement time cannot be easily determined, and when the magnetic filter is replaced or the chips collected from the magnetic filter are removed, the filtration device and its peripheral parts must be dismantled. This is complicated and there is a problem that it is impossible to confirm the presence of the chip in the oil before decomposition.

Therefore, the present invention has been devised to solve the above problems, in order to easily check whether the iron chip contained in the fluid flowing in the pipe, the upper cap, and the head portion to which the upper cap is fitted and covered; And an inner tube having a predetermined length coupled to the head portion and having a chip detecting magnet attached to the opposite end thereof, and detachably coupled to the inner tube with the chip detecting magnet and the inner tube inserted inward. By providing a portable pipe chip inspection mechanism including a tubular body portion, it is possible to easily check whether the chip in the fluid even in multiple locations of the pipe on the fly, and eventually, through the occasional check without complicated disassembly, accidents due to the inclusion of the chip in the fluid Its purpose is to enable it to be prevented in advance.
