Description

  The present invention relates to a liquid sampling jig that enables sampling at the same location when collecting liquid such as lubricating oil of a pump.

  A variety of rotating machines are in operation at the power plant, and the lubricating oil used there is suitable for the application of the rotating machine. By analyzing and evaluating the deterioration of these lubricants and monitoring the deterioration tendency, it becomes possible to detect deterioration progress and signs of equipment abnormality early.

  In order to manage the lubricating oil, it is necessary to first collect a sample of the lubricating oil from the rotating machine, but in order to make the lubricating oil manageable, the same conditions (always the same location, the same conditions) are required. It is necessary to collect and analyze / evaluate.

  FIG. 3 shows a conventional sampling method. The current sampling method is that the tube is straight formed by hand so that it does not become round during storage, the insertion depth at the time of sampling is marked on the tube, and the sampling tube (made of polyurethane) is vented to the top of the tank Insert from the filter hole, fix the tube by hand according to the marking on the tube, and collect the lubricating oil in the tank using a manual vacuum pump.

  However, in the conventional sampling method, even if the sampling tube is formed (straight), it is bent in the oil tank, and the position of the inserted tube becomes unstable. Moreover, since the position of the collection tube becomes unstable due to the oil flow in the oil tank, it cannot be sampled from the same position in the oil tank. Furthermore, there are various problems such as the need to mark the insertion depth at the time of collection on the tube for each pump. For this reason, it takes about 30 minutes to collect.

  The present invention has been made to solve such a conventional problem, and is intended to provide a liquid sampling jig capable of collecting a liquid such as lubricating oil from the same position in an oil tank. is there.

  The liquid collecting jig of the present invention extends in a direction substantially perpendicular to the guide tube, a guide tube into which a collection tube for collecting the liquid in the tank from the tank is inserted, a hole for inserting and fixing the guide tube, And a fixing jig having a support bar.

  According to the liquid collecting jig of the present invention, a liquid collecting jig is formed by combining a collecting tube guide tube and a guide tube position fixing jig, and the collecting tube is inserted into the guide tube to collect lubricating oil. Thereby, it can extract | collect from the same position in an oil tank, a collection position becomes clear, can improve the reliability of a sample, and can also improve workability | operativity on the spot.

It is a front view of the jig for liquid collection of this embodiment. It is a figure which shows the method of extract | collecting using the jig for liquid collection of this embodiment. It is a figure which shows the conventional collection method.

  Hereinafter, the liquid sampling jig of this embodiment will be described in detail with reference to the drawings.

  FIG. 1 is a front view of the liquid sampling jig of the present embodiment. The liquid collecting jig 1 according to the present embodiment includes a guide tube 20 capable of inserting the collecting tube 10 therein, and a fixing jig 30 for fixing the guide tube 20.

  The guide tube 20 is a hollow circular tube and has an inner diameter that allows the collection tube 10 to be inserted therein. The guide tube 20 may be long enough to reach the bottom of the oil tank to be collected. A scale 20a is provided on the upper side surface of the guide tube 20 to indicate the amount of protrusion of the guide tube 20 from the fixing jig 30, thereby making it possible to visually check the fixing position. This is a guide for adjusting the sampling position. By having such an adjustable mechanism, the liquid sampling jig 1 can be applied to oil tanks of various depths.

  The fixing jig 30 is a member that intersects the guide tube 20 substantially orthogonally. The fixing jig 30 includes a fixing portion 30d into which the guide tube 20 is inserted and fixed, a first support rod 30c attached to the fixing portion 30d and extending in a direction substantially orthogonal to the guide tube 20, and a fixing portion 30d. And a second support bar 30a that is substantially orthogonal to the guide tube 20 and extends in the opposite direction to the first support bar 30c.

  The fixed portion 30d has a hole through which the guide tube 20 can pass, and a hole that intersects the hole vertically and into which the second support rod 30a is inserted. A nut 30b is welded to the hole into which the second support rod 30a is inserted, and the side surface of the guide tube 20 is pressed by screwing with a screw portion formed at the tip of the second support rod 30a. Then, the guide tube 20 is fixed. In the present embodiment, an anchor bolt or an eye bolt is used for the second support rod 30a. Further, the method of fixing the guide tube 20 is not limited to this, and the guide tube 20 may be fixed with a bolt separate from the support rod.

  FIG. 2 is a diagram showing a method of collecting using the liquid collecting jig of the present embodiment. As shown in the figure, the liquid collecting jig 1 of the present embodiment is configured such that the fixing jig 30 is hooked at, for example, the entrance of the filter B provided in the collecting port of the oil tank A, and the guide tube 20 is connected to the oil surface C of the oil tank A. Below, it inserts so that the front-end | tip part 10a of the collection tube 10 may be arrange | positioned. Here, it is preferable that the size of a part of each part of the liquid sampling jig 1 of this embodiment is larger than the filter hole (collecting port). This prevents foreign matter from entering the tank. Further, it is preferable to adjust the length of the guide tube 20. Thereby, even if the guide tube 20 drops off from the fixing jig 30, the tip of the guide tube 20 comes out from the oil surface, and recovery can be facilitated.

  As described above, according to the liquid sampling jig of the present embodiment, it becomes possible to collect the lubricating oil with higher accuracy by clarifying the sampling position.

  Further, since the collection tube is passed through the guide tube 20, the tube forming operation is not necessary. Further, since the guide tube 20 is a straight tube and the insertability is improved, the tube insertion time is reduced to about half. Furthermore, since the tip of the guide tube 20 is always at the same position, marking on the tube is unnecessary. In addition, it is not necessary to fix the tube at the tank collection port during collection. Even if the tube insertion position is shifted and the distal end portion 10a of the collection tube 10 does not reach the distal end of the guide tube 20, there is no problem because the lubricating oil is always collected from the distal end of the guide tube 20 at the same position. .

  In addition, a scale is provided on the surface of the guide tube 20 so that the sampling position can be confirmed visually. The position fixing jig can be used and is versatile. The fixing position (height) of the fixing jig can be changed or replaced with a fixing jig of another size.

  The liquid collecting jig can be divided into the guide tube 20 and the fixing jig 30 and can be easily handled and carried. Each part is larger than the filter hole (sampling port) to prevent contamination.

  In order to collect the lubricating oil (from the oil pan) of the emergency diesel engine, the liquid sampling jig of this example was manufactured. The collection tube guide tube was about 2m long. Thereby, even if the collection tube guide tube falls off the fixing jig, the tip of the guide tube comes out of the oil pan portion.

  As a result of the evaluation, especially the lubricating oil of diesel engines has a high viscosity (using ISO-103 etc.), so it took time (about 30 minutes) to collect, but by using the sampling tube guide tube, Since the collection tube is not bent, the length of the collection tube is shortened, and the resistance during collection (lubricating oil) is reduced, the effect of greatly shortening the collection time (about 30 to 15 minutes) is achieved. there were.

  According to the liquid sampling jig of the present invention, not only the lubricating oil, but also any liquid in the tank (for example, a liquid in a food separation tank or a pollution sedimentation tank), the upper layer / middle layer in the tank / It can be applied to various uses such as collecting samples of impurities or liquid concentration from any position in the lower layer.
