Description

Technical Field

[0001] The utility model relates to the technical field of natural gas purification and treatment, and specifically to a device and a compressor that utilizes splash energy to increase the amount of lubricating oil in a compressor. Background Art

[0002] The lubricating oil of each compression rod of a natural gas compressor generally comes from the crankcase of the compressor. The lubricating oil of the crankcase is pressurized by an oiler and enters each compression rod to play a role of lubrication and sealing.

[0003] Because the lubricator is generally driven by the compressor main shaft, the position of the lubricator is higher than the oil level of the crankcase. The lubricating oil in the crankcase cannot flow into the lubricator by gravity, but can only enter the lubricator by means of an external oil pump or by diverting it from the main oil pump.

[0004] On the one hand, the prior art uses an external oil pump to lift the oil from the crankcase into the oiler, which requires an external oil pump and a corresponding automatic control system to ensure that the oil level in the oiler is within a suitable range. On the other hand, a path is separated from the main oil pump to enter the oiler, but a corresponding automatic control system is also required to control the amount of oil entering the oiler from the main oil pump to ensure that the oil level in the oiler is within a suitable range, or the amount of oil entering the oiler from the main oil pump is controlled manually. Both of the above methods require an external oil pump to lift the crankcase lubricating oil, which not only consumes energy, but also increases the number of equipment and manufacturing costs; secondly, the increase in the number of equipment and the installation of the control system reduces the reliability of the oil supply system. When the amount of oil entering the oiler is insufficient, the compressor will shut down due to lack of oil; when the amount of oil entering the oiler is excessive, the lubricating oil will overflow excessively and pollute the equipment and the environment. Finally, if the method of manually controlling the entry into the oiler is adopted, personnel are required to operate on site regularly, which increases the labor intensity of the operators. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art and provides a device and a compressor for increasing the amount of lubricating oil in a compressor by utilizing splashing energy.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In a first aspect, a device for increasing the amount of lubricating oil in a compressor by utilizing splash energy is provided, comprising:

[0008] A collecting member, mounted on the crankcase and communicated with the interior of the crankcase;

[0009] The enclosure member is installed in the collecting member and forms an oil collecting groove with the inner wall of the collecting member;

[0010] The conveying member has one end connected to the collecting member and located in the oil collecting tank, and the other end is a free end.

[0011] Furthermore, the enclosure is installed at one end of the collecting member communicating with the interior of the crankcase, one end of the enclosure is connected to the side wall of the collecting member, and the other end extends to an end away from the crankcase.

[0012] Furthermore, the enclosure is an L-shaped structure.

[0013] Furthermore, the longer end of the enclosure member is connected to the side wall of the collecting member.

[0014] Furthermore, the conveying member is a tubular structure.

[0015] Furthermore, the cross section of the oil collecting tank is rectangular.

[0016] Furthermore, the length of the oil collecting tank is equal to the width of the collecting member.

[0017] Furthermore, the oil collecting tank is located above the crankcase.

[0018] Furthermore, the cross section of the collecting member is rectangular.

[0019] In a second aspect, a compressor is provided, wherein the device as described above is installed on the crankcase of the compressor.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. By installing the collecting piece on the crankcase of the compressor and connecting the collecting piece with the inside of the crankcase, the lubricating oil splashed out due to the operation of the crankshaft in the crankcase enters the collecting piece and is collected by the oil collecting tank. Since the collecting tank is located above the crankcase, the collected lubricating oil in the collecting tank can automatically flow to the oil injector through the conveying piece to convey the lubricating oil to each compression rod of the compressor. This not only solves the problem of the external oil pump in the prior art and increases the operating cost, but also replaces the manual operation and realizes automatic oil injection.

[0022] 2. By utilizing the connection between the enclosure and the collecting member, it is possible to transport the lubricating oil from the lower crankcase to the higher oiler without adding an oil pump, thereby reducing the consumption of external energy and lowering the operating cost.

[0023] 3. The L-shaped enclosure can effectively collect the lubricating oil in the oil collecting tank, avoiding the problem of lubricating oil leakage.

[0024] 4. The longer end of the enclosure is connected to the side wall of the collecting piece, which can further increase the storage capacity of the lubricating oil collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The embodiment of the utility model provides a device and a compressor for increasing the amount of lubricating oil in a compressor by utilizing splashing energy.

[0036] In a first aspect, a device for increasing the amount of lubricating oil in a compressor by utilizing splash energy is provided. Figure 1 As shown, the device includes a collecting member 1. The collecting member 1 is a box structure with one end open and the other end blocked. The open end is connected to the inside of the crankcase 7. A blocking member 2 is installed in the end of the collecting member 1 connected to the crankcase 7. One end of the blocking member 2 is connected to the side wall of the collecting member 1, and the other end extends to the end away from the crankcase 7, wherein the longer end of the blocking member 2 is connected to the side wall of the collecting member 1, and an oil collecting groove is formed between the collecting member 1 and the inner wall of the collecting member 1. In order to facilitate the transportation of the lubricating oil collected in the oil collecting groove to the oiler 3, a conveying member 5 is used to connect the collecting member 1 and the oiler 3. One end of the conveying member 5 is located in the oil collecting groove, and the free end of the conveying member 5, that is, the conveying member inlet 6 is connected to the oiler 3. As shown Figure 2As shown, by installing the collecting member 1 on the crankcase 7 of the compressor and connecting the collecting member 1 with the inside of the crankcase 7, the lubricating oil splashed out by the crankshaft in the crankcase 7 enters the collecting member 1 and is collected by the oil collecting tank.

This not only solves the problem of adding an external oil pump in the prior art, increasing operating costs, but also requires manual operation, thereby realizing automatic oiling. By utilizing the connection between the enclosure 2 and the collecting member 1, it is possible to convey the lubricating oil from the low-positioned crankcase 7 to the high-positioned oiler 3 without adding an oil pump, thereby reducing the consumption of external energy and lowering operating costs.

[0037] In this embodiment, the conveying member 5 is a tubular structure.

[0038] In this embodiment, the cross section of the oil collecting groove is rectangular, and the length of the oil collecting groove is equal to the width of the collecting member 1.

[0039] In this embodiment, the oil collecting tank is located above the crankcase 7.

[0040] In this embodiment, the cross section of the collecting member 1 is rectangular.

[0041] In a second aspect, a compressor is provided, wherein the device as described above is installed on the crankcase 7 of the compressor.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
