Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
As shown in fig. 1, the automatic oil supplementing device for a compressor comprises a compressor 1 and an oil tank 2, wherein the oil tank 2 is arranged at a height greater than that of the compressor 1, a first reducing sleeve 3A, a gear pump 4, a regulating valve 5, a mass flowmeter 6 and a second reducing sleeve 3B are sequentially arranged on a pipeline between the oil tank 2 and the compressor 1, the first reducing sleeve 3A is close to the oil tank 2, the second reducing sleeve 3B is close to the compressor 1, a communicating vessel 7 is arranged outside a crankcase 11 of the compressor 1, and a liquid level sensor 8 is arranged on the communicating vessel 7. Wherein the liquid level sensor 8, the mass flowmeter 6, the regulating valve 5 and the gear pump 4 are electrically connected with the main controller M.
The regulator valve 5 is an electric regulator valve.
The bottom of the communicating vessel 7 communicates with the crankcase 11 of the compressor 1 via a hose 9, and the liquid level sensor 8 is provided at the level of the communicating vessel 7.
The first variable diameter sleeve 3A is disposed laterally, and the second variable diameter sleeve 3B is disposed longitudinally.
The first reducing sleeve 3A and the second reducing sleeve 3B each comprise a tubular first connecting pipe S1 and a tubular second connecting pipe S3, the inner diameter of the first connecting pipe S1 is larger than that of the second connecting pipe S3, and a horn-shaped reducing connecting pipe S2 is arranged between the first connecting pipe S1 and the second connecting pipe S3.
In addition, the first connecting pipe S1 is welded to the reducing connecting pipe S2, and the second connecting pipe S3 is welded to the reducing connecting pipe S2.
The operation of the automatic oil compensating device of the compressor will be described.
As shown in fig. 1, when the liquid level sensor 8 of the communicating vessel 7 detects that the oil level of the crankcase 11 of the compressor 1 is lower than the limit value, the main controller M instructs the start of the gear pump 4 and the full opening of the regulator valve 5, and the lubricant is supplied from the oil tank 2 into the crankcase 11.
When the liquid level sensor 8 of the communicating vessel 7 detects that the oil level of the crankcase 11 of the compressor 1 is at a certain value, the main controller M instructs the regulating valve 5 to close a part, and small flow delivery is performed. When the flow reaches a certain value, the mass flowmeter 6 triggers an alarm signal, the main controller M instructs the gear pump 4 to be closed, the regulating valve 5 is fully closed, and the conveying is finished. At this time, the oil remaining in the second reducing sleeve 3B slowly enters the crankcase 11 of the compressor 1, and the oil replenishment is completed.
It should be noted that, since the crankcase 11 has a certain air pressure, the oil cannot fill the pipe during oil filling, and a portion of the pipe space needs to be reserved for return air, and the transmission characteristic of the pipe causes that the oil fills the whole pipe during oil filling. Therefore, the first reducing sleeve 3A is arranged at the position of the high outlet of the gear pump 4 and is used for the backflow of part of oil, so that the state that the liquid in the pipeline is not a full pipe when the gear pump 4 pumps out the oil is realized. Meanwhile, by means of intermittent control of the regulating valve 5 and the gear pump 4, the condition that oil is in a low-pressure and non-full pipe state when being conveyed in a pipeline is ensured, and therefore the condition that air blockage is not sent when liquid is replenished is ensured.
In addition, as the mass flowmeter 6 is controlled by the main controller M, the liquid level and the oil delivery quantity of the oil tank are not more than the limit of the oil tank, and the oil is prevented from being sprayed out.
The automatic oil supplementing device for the compressor solves the problems that the structure of the compressor equipment is precise, the related liquid level detector cannot be directly installed, the equipment is not timely filled with lubricating oil, the abrasion and the service life are reduced, and the problems that the lubricating oil needs to be frequently filled in the field and the workload is large. The oil level real-time monitoring function of the special equipment of the oil and gas field is realized by flexibly applying the communicating vessel principle, lubricating oil is intelligently filled through the combination of the equipment, the normal operation of the special equipment is ensured, the service life of the equipment is prolonged, the labor intensity of workers is reduced, the automation and the intelligent upgrading of the special equipment of the oil and gas field are realized, and the powerful support is provided for the construction of an intelligent well site.
Without being limited thereto, any changes or substitutions that are not contemplated by the inventors are intended to be included within the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
