Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides (1) a compressor oil lubrication device suitable for centrally monitoring the state of droplets in a lubrication device that lubricates lubricating oil into, for example, a pressure-feeding reciprocating compressor; management system.

[Prior Art] Generally, in reciprocating compressors for pressure feeding installed in city gas supply facilities, for example, one lubricator is used for each drive system that requires lubrication of multiple compressor bodies. In addition to supplying lubricating oil, safety management measures are taken by centrally monitoring the condition of the lubricating oil droplets to each of these drive systems using visible cylinders installed in the respective oil supply routes of the lubricators. It is being

However, conventionally, when monitoring the state of droplets in the visible cylinders of such lubricators, the number of visible cylinders for one compressor body is extremely large (18, for example), and these are operated one by one. Currently, this is carried out by a person who regularly inspects and checks visually.

[Problems to be Solved by the Invention] For this reason, conventionally, monitoring the state of droplets in the visible cylinder requires a great deal of effort and time, which is a major hindrance to achieving one-money luck.

The present invention was made under the above circumstances.

The purpose is to provide a management system for compressor lubricators that can streamline monitoring work.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a system in which each of a number of visible tubes installed in each of the lubrication devices for a plurality of compressor bodies is capable of confirming the state of lubrication. A detection means using an optical fiber sensor is provided, and the detection information from each of these detection means is centrally displayed on a management section via a controller panel and an alarm panel to monitor and control the operating status of each of the compressors. This is a characteristic feature.

[Function] By having the above configuration, the present invention has the following features:
Optical fiber sensors are used to monitor the state of droplets in the visible cylinder, and the lubrication state of the drive system of each compressor body during operation is automatically and centrally monitored, and an alert is sent to the control center when an abnormality occurs. Since it is possible to output , there is no need to visually check a large number of visible cylinders one by one as in the past, and this makes it possible to greatly improve the rationalization of monitoring work.

[Example] Hereinafter, two aspects of the present invention will be described in detail with reference to an illustrated example.

As shown in FIG. 1, reference numeral 1 in the figure is a lubricator used to apply lubricating oil to each drive system of a reciprocating compressor for pumping according to the present invention. On the upper surface of this lubricator 1, visible cylinders 2 made of transparent cylinders are provided at predetermined intervals so that the state of droplets can be monitored to confirm the lubricant layer applied to each drive system of the compressor main body (not shown). A large number of visible cylinders 2 are arranged along the oiling path, and the outer circumferential surface 2a of each of these visible cylinders 2 is
Detecting means 10 each comprising a pair of optical fiber beam sensors, for example, a light-emitting fiber sensor 3 and a light-receiving fiber sensor 4, is installed.

The detecting means 10 includes 1 as shown in FIGS.
Light emitting part 3a of a pair of optical fiber set beam sensors consisting of a light emitting fiber sensor 3 and a light receiving fiber sensor 4
and the light receiving section 4a are positioned and held so as to face each other in a diametrical direction passing through the central axis 0-0 of the visible cylinder 2. That is, in order to attach these sensors, a holding part 12 having a diameter substantially equal to the outer diameter of the visible tube 2 is formed approximately at the center of a symmetrical ring-shaped belt body 11 bent by a plate spring member. , this holding part 12 can be inserted into the outer circumferential surface 2a of the visible tube 2 from above or from the side, while the holding part 12 of the belt body 11 exists in between, and the holding part 12 is provided at both ends thereof. The belt body 11 is formed by bending first and second supporting parts 13 and 14 that face each other in the diametrical direction passing through the central axis o-O of the visible cylinder 2.
The holding part 12, which can be inserted into the frame a, and one support part 13 are continuously bent into one piece by a single plate spring member, and both ends of this plate spring member are connected to the other support part. 14 and are formed by overlapping and bending, and both support parts 13 and 14 of the ring-shaped belt body 11.

The first and second sensor support blocks 15 and 17 that come into contact with the outer circumferential surface 2a of the visible cylinder 2 are respectively inserted. These sensor support block bodies 15.
A contact surface 15a that comes into contact with the outer circumferential surface 2a of the visible cylinder 2 of No. 17
, 17a are formed into concave surfaces having the same diameter as the outer diameter of the visible cylinder 2.

Each head has a screw-shaped through hole 16 into which the light emitting part 3a of the light emitting fiber sensor 3 and the light receiving part 4a of the light receiving fiber sensor 4 are inserted and held in a screwed state.
．． 18 is formed through the visible cylinder 2 in the diametrical direction passing through the central axis o-0, and the central axes P-P of each of these through holes 16 and 18 are located on the same straight line, so that the visible cylinder 2 is held. That's what happens.

In addition, 19 in the figure is the second support portion 14 of the belt body 11.
The tightening installed on the side is a nut, and this tightening is nut 19.
In this case, the bolt 2 is inserted from the outside into the insertion hole 20 provided in the overlapping curved portion on both ends of the leaf spring member.
1 are screwed together, and the tightening is performed by pressing the second sensor support block body 17 toward the outer peripheral surface 2a side of the visible cylinder 2 with the tip 21a of the bolt 21. The tightening is done by tightening the bolt 21 from one side, and the detection means 10 is positioned and fixed at an appropriate position in each visible cylinder 2. As a result, as in the conventional case, Compared to a system that detects the state of droplets by connecting a detector consisting of an inlet pipe to the oil supply pipe on the oil supply route and bringing the droplets into direct contact with each other, it is possible to The detection means 1 is attached to the cylinder 2.
0 can be simply and easily attached from the outside without contact with liquid droplets.

By the way, in the above embodiment, the belt body 11 is
The holding part 12 and one support part 13 are continuously bent into one piece by a single leaf spring member, and the other support part 14 side is formed by overlapping both ends of this leaf spring member. Attach the nut 19 for tightening and the bolt 21 for tightening, and attach each sensor support block body 15.17 from one side to the visible cylinder 2.
However, for example, the belt body 11 can be formed into a symmetrical shape by integrally bending a half-holding part and a half-supporting part that are fitted onto the outer circumferential surface 2a of the visible cylinder 2. The surface support part 13 is formed by a pair of divided leaf spring members which are combined into a pair of leaf spring members.
．． A tightening nut 19 and a tightening bolt 21 are respectively attached to the 14 side, and each of the sensor support block bodies 15 is
．． 17 can be compressed and fastened from both sides, or the visible@2 itself is molded from synthetic resin such as acrylic resin, and at the same time each sensor support block body 1 is molded.
It is also possible to integrally mold 5.17,
The selection is arbitrary.

In this way, the detection information of the lubrication state from the detection means 10 installed in each visible pipe 2 of the lubrication device 1 of each compressor main body is transmitted to the controller panel 101 and the alarm as shown in FIG. After being processed by a computer (not shown) via the panel 102, the display panel 1 of the central control room 100
03, and is designed to output an alarm when an abnormality occurs.This allows the lubrication status of each drive system of each lubrication device of multiple compressors to be centrally displayed. This makes it possible to monitor and control the

In the above embodiment, a transmission type sensor is used as the detection means 10 installed in the visible tube 2, but the present invention is not limited to this, and a reflection type sensor may also be used.

In addition, it goes without saying that the present invention can be modified in various ways without departing from the gist of the invention.

[Effects of the Invention] As is clear from the above description, according to the present invention, an optical fiber sensor is installed in each of a large number of visible tubes that can confirm the oiling state installed in each oiler for a plurality of compressor bodies. The detection information from each of these detection means is centrally displayed on the management section via the controller panel and alarm panel, and the lubrication status of the drive system of each compressor body during operation can be automatically checked. Moreover, since it is possible to centrally monitor and output an alarm to the control center when an abnormality occurs, there is no need to visually check a large number of visible cylinders one by one as in the past. This greatly improves the streamlining of monitoring work, and since the detection means can be positioned and fixed from the outside at the appropriate position of each visible tube, existing This provides excellent effects such as the ability to simply and easily attach the detection means to the visible tube without contacting the liquid droplet.
