Description

Technical Field

[0001] The present invention relates to the technical field of anti-seepage oil for compressor units, and particularly relates to an anti-seepage oil device for a compressor unit detection line and a using method thereof. Background Art

[0002] During the daily operation of compressor units, it is found that many centrifugal compressors have the following problems during operation: lubricating oil penetrates from the connection heads of the detection lines (vibration measurement lines and temperature measurement lines) at the driving end and non-driving end of the compressor into the wire pipes, and then flows from the wire pipes into the explosion-proof junction box on one side of the compressor unit. On the one hand, the lubricating oil leaks from the junction box to the bottom surface. At present, most compressors seal the connection heads on the inner side of the box cover with adhesive during factory production. However, as the equipment operates, the adhesive detaches from the wire and the cable channel, forming a gap. And the lubricating oil will generate oil mist in an environment of 50°C, and it continuously penetrates into the wire pipe through the gap.

[0003] This is not only a waste of energy resources, but also likely to cause staff to slip and pose a safety hazard. On the other hand, when too much lubricating oil accumulates in the junction box, it is easy to return to the wiring main pipe, thereby causing a short circuit in the line, abnormal signals, resulting in chain shutdown, and even faults such as unit out-of-control, thus affecting the safe and stable operation of the pipe network and production. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an anti-seepage oil device for a compressor unit detection line and a using method thereof. By respectively arranging fastening and sealing members with sealing parts on both the inner and outer sides of the box cover to solve the sealing between the detection line and the box cover, it can avoid the penetration of lubricating oil into the explosion-proof junction box and ensure the normal operation of the compressor unit.

[0005] The purpose of the present invention is achieved through the following technical solutions: An anti-seepage oil device for a compressor unit detection line includes a box cover installed on the compressor unit. At least one through wiring hole is provided on the box cover, and fastening and sealing members for sealing the gap between the detection line and the box cover are respectively provided at positions corresponding to the wiring holes on both the inner and outer sides of the box cover; The detection line sequentially passes through the fastening and sealing members on the inner and outer sides to the outside of the compressor.

[0007] Further, a plurality of wire passing holes corresponding to the number of sub-wires of the detection line are provided on the sealing part, and the sub-wires of the detection line pass through the wire passing holes.

[0008] Further, the sealing portion is made of fluorosilicone rubber.

[0009] Further, it further includes a positioning wire clip. The positioning wire clip is arranged on the lower side of the fastening seal. The detection wire is connected to the fastening seal after passing through the positioning wire clip. The detection wire bends at the positioning wire clip to form a free dripping point for lubricating oil.

[0010] Further, the positioning wire clip is of a rod structure. The positioning wire clip is provided with a fixing component for fixing the detection wire. The fixing component includes a connecting seat connected to the positioning wire clip. The connecting seat is provided with a fixed clamping block and a movable clamping block. The movable clamping block has a first end and a second end. The first end of the movable clamp is close to the fixed clamping block and is rotatably connected to the connecting seat. A fixing gap for the detection wire to pass through is formed between the fixed clamping block and the first end of the movable clamp.

Specific embodiments

[0018] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Refer to Figures 1 - 5 , the present invention provides a technical solution: Embodiment 1: As Figure 1 and Figure 2 shown, an anti-oil-leakage device for a compressor unit detection line includes a box cover 1 installed on the compressor unit. At least one wiring hole is provided through the box cover 1. Fastening seals 2 for sealing the gap between the detection line 3 and the box cover 1 are respectively provided at the positions corresponding to the wiring hole on both the inner and outer sides of the box cover 1; the fastening seal 2 includes a gland head, and a sealing part made of fluorosilicone rubber is provided inside the gland head. The detection line 3 passes through the sealing part, and the fastening seal 2 is threadedly connected to the box cover 1; The detection line 3 sequentially passes through the fastening seals 2 on the inner and outer sides to the outside of the compressor.

[0020] A plurality of wire threading holes 4 corresponding to the number of sub-lines of the detection line 3 are provided on the sealing part, and the sub-lines of the detection line 3 pass through the wire threading holes 4.

[0021] It further includes a positioning wire clip 5. The positioning wire clip 5 is arranged on the lower side of the fastening seal 2. The detection line 3 is connected to the fastening seal 2 after passing through the positioning wire clip 5, and the detection line 3 is bent at the positioning wire clip 5 to form a free dripping point for lubricating oil.

[0022] When the position of the wiring hole is relatively low and the position of the internal cable outlet is at the lower end, due to the temperature drop during the operation and shutdown processes, after the oil mist condenses into droplets on the cable wrapping the detection line 3, it will penetrate into the wiring hole along the cable wall, resulting in the leakage of lubricating oil. Therefore, by setting the free dripping point of the lubricating oil liquid, the condensed oil droplets can be accumulated in the unit through the free dripping point of the lubricating oil liquid, and then only regular cleaning is required.

[0023] The present invention solves the sealing between the detection line 3 and the box cover 1 by respectively arranging fastening seals 2 with sealing parts on the inner and outer sides of the box cover 1, which can prevent the lubricating oil from penetrating into the explosion-proof junction box and ensure the normal operation of the compressor unit; at the same time, by setting the positioning wire clip 5, a free dripping point of the lubricating oil liquid is formed for the detection line 3, so that the condensed oil droplets are accumulated in the unit through the free dripping point of the lubricating oil liquid, avoiding the problem of lubricating oil leakage during the temperature drop.

[0024] Embodiment 2 As Figure 1 、 Figures 3 - 5 shown, on the basis of Embodiment 1, the positioning wire clip 5 is of a rod structure, and a fixing component for fixing the detection line 3 is arranged on the positioning wire clip 5. The fixing component includes a connecting seat 7 connected to the positioning wire clip 5. A fixing clip 8 and a movable clip 9 are arranged on the connecting seat 7. The movable clip 9 has a first end and a second end. The first end of the movable clip is close to the fixing clip 8 and is rotatably connected to the connecting seat 7, and a fixing gap for the detection line 3 to pass through is formed between the fixing clip 8 and the first end of the movable clip. The second end of the movable clip is freely arranged, and a spring 10 is arranged between the second end of the movable clip and the connecting seat 7. A guide sleeve 11 is arranged on the connecting seat 7, and the end of the spring 10 away from the movable clip is fixed in the guide sleeve 11.

[0025] A connecting block 6 is arranged on the connecting seat 7, and the first end of the movable clip is connected to the connecting block 6 through a rotating shaft. When the second end of the movable clip is pressed, the movable clip moves around the axis of the rotating shaft, thereby expanding or shrinking the fixing gap.

[0026] External threads are arranged on the positioning wire clip 5, and threaded holes adapted to the external threads are arranged on the connecting seat 7. The connecting seat 7 is threadedly connected to the positioning wire clip 5.

[0027] When the second end of the movable clip is pressed, the movable clip moves around the axis of the rotating shaft, thereby expanding or shrinking the fixing gap so that detection lines 3 with different wire diameters can be fixed on the positioning wire clip 5. The fixation of the detection line 3 can prevent the detection line 3 from slipping off the positioning wire clip 5, causing the free dripping point of the lubricating oil liquid to shift and resulting in oil leakage again.

[0028] Meanwhile, the threaded connection between the connecting seat 7 and the positioning wire clip 5 can facilitate the adjustment of the relative positions of the connecting seat 7 and the positioning wire clip 5, and further adjust the position of the free dripping point of the lubricating oil.

Install the box cover 1 on the compressor unit; S2. Pass the detection line 3 through the fastening seal 2 on the inner side of the box cover 1 and out through the fastening seal 2 on the outer side; S3. After the detection line 3 passes through, fix the detection line 3 on the positioning wire clip 5 through the fixed gap, and bend the detection line 3 at the positioning wire clip 5 to form a free dripping point of the lubricating oil.

[0030] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in the relevant field.
