Description

Technical Field

[0001] This utility model relates to the field of lubricating oil sampling technology, and in particular to an air compressor lubricating oil sampling device and oil tank. Background Technology

[0002] An air compressor is a velocity compressor. A drive motor drives the impellers on the main gear and various speed-increasing gear shafts, causing the impellers to rotate at high speed. Under the influence of negative pressure at the center of the impeller, gas enters axially and is thrown out of the impeller at high speed by centrifugal force, generating centrifugal motion. The normal operation of an air compressor relies on lubricating oil, and it is usually equipped with an oil tank. The lubricating oil in the tank flows through various parts of the air compressor and then returns to the tank. To ensure the effectiveness of the lubricating oil, it is necessary to periodically sample and analyze the lubricating oil in the tank.

[0003] Traditionally, the method for sampling lubricating oil from air compressors involves opening the cap on the oil tank, inserting one end of the sampling tube into the tank, and the other end into the sampling bottle. The lubricating oil is then drawn out of the tank using a siphon effect. This process requires the use of external objects such as syringes and squeeze balls to create negative pressure and expel air from the sampling tube. The operation is cumbersome and requires operators to support both the sampling tube and the sampling bottle simultaneously. Furthermore, lubricating oil is easily spilled into the environment during the operation, resulting in lubricating oil waste and environmental pollution.

[0004] Therefore, a technical solution is needed to address the cumbersome operation of inserting a sampling tube into the air compressor oil tank and using siphon action to introduce the lubricating oil from the tank into the sampling bottle, which also results in the lubricating oil easily spilling into the environment. Utility Model Content

[0005] The purpose of this invention is to overcome the technical problems of cumbersome operation and easy spillage of lubricating oil into the environment by inserting the sampling tube into the air compressor oil tank and using siphon effect to introduce the lubricating oil in the oil tank into the sampling bottle. This invention provides an air compressor lubricating oil sampling device and oil tank.

[0006] In a first aspect, the present invention provides an air compressor lubricating oil sampling device, including a drain pipe, an air lift pump and a valve on the drain pipe, the drain pipe being used to connect to the oil tank of the air compressor, and a sampling bottle being detachably provided at the end of the drain pipe.

[0007] This utility model relates to a lubricating oil sampling device for air compressors. In use, an air lift pump is installed on the oil tank of the air compressor, one end of the drain pipe extends into the oil tank, and the other end of the drain pipe is connected to a sampling bottle. The valve on the drain pipe is opened, and the air lift pump is started to draw the lubricating oil in the oil tank into the sampling bottle.

[0008] Preferably, a magnetic ring is fitted at the end of the drainage tube, and an iron ring adapted to the magnetic ring is provided at the mouth of the sampling bottle.

[0009] The magnetic ring and the iron ring are connected by adsorption, thus realizing the detachable connection between the sampling bottle and the drainage tube. On the one hand, it ensures the sealing during the sampling process and prevents the lubricating oil from spilling when entering the sampling bottle. On the other hand, it is easy to disassemble and assemble, and improves the sampling efficiency.

[0010] Preferably, the magnetic ring is an electromagnet.

[0011] This design enhances the magnetic ring's adsorption capacity, preventing the sampling bottle from accidentally falling off during the sampling process. Additionally, it makes it easier for the magnetic ring to separate from the sampling bottle after the power is disconnected, preventing the lubricating oil inside the sampling bottle from spilling during the separation process.

[0012] Preferably, the magnetic ring has an annular groove, and an elastic sealing ring is provided inside the annular groove.

[0013] Under the attraction of the electromagnet, the elastic sealing ring in the annular groove can adhere tightly to the surface of the iron ring, thereby improving the sealing performance between the magnetic ring and the iron ring and further preventing spillage during the sampling of lubricating oil.

[0014] Preferably, the sampling bottle is a transparent structural component.

[0015] This allows operators to easily observe the level of lubricating oil in the sampling bottle, thus facilitating accurate control of the sampling amount, ensuring sufficient sample quantity, and preventing excessive lubricating oil spillage.

[0016] Preferably, it further includes a support plate and a base, the support plate having holes for mounting the magnetic ring, and a plurality of columns being provided between the base and the support plate.

[0017] It provides support for the magnetic ring and the drainage tube, ensuring that the drainage tube and sampling bottle are in a stable position during the sampling process, eliminating the need for manual support and making the operation simpler.

[0018] Preferably, an annular limiting plate is provided at the bottom of the hole, and the magnetic ring is disposed on the annular limiting plate.

[0019] The magnetic ring is fixed on the support plate by limiting the position of the ring at the bottom of the hole, which simplifies the process and makes it easier to install and remove the magnetic ring from the support plate.

[0020] Preferably, the base is provided with a detachable oil collection tray, which is located directly below the magnetic ring.

[0021] After sampling, any residual lubricating oil in the drainage tube will easily fall into the oil collection tray. The oil collection tray collects the residual lubricating oil, preventing it from dripping into the environment and causing pollution.

[0022] Preferably, the base is provided with a limiting groove that matches the shape of the oil collecting tray, and the oil collecting tray is disposed in the limiting groove.

[0023] The system enables a detachable connection between the oil collection tray and the base, and the limiting groove guides the installation of the oil collection tray. After cleaning the oil collection tray, the operator can accurately install the oil collection tray back into its original position, thereby ensuring that the oil collection tray can accurately collect the residual lubricating oil in the drainage pipe.

[0024] In a second aspect, the present invention provides an air compressor oil tank, including a tank body, and also includes an air compressor lubricating oil sampling device as described above.

[0025] This utility model relates to an air compressor oil tank. When it is necessary to sample the lubricating oil in the tank, the sampling bottle is connected to the end of the drain pipe, the valve on the drain pipe is opened, and the air lift pump is started at the same time to draw the lubricating oil in the tank into the sampling bottle.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. The present invention provides an air compressor lubricating oil sampling device, which adds an air lift pump to the existing air compressor oil tank. The air lift pump is connected to the inside of the tank through a drain pipe. During the sampling process, the air lift pump is used to extract the sample, making the operation simpler.

[0028] 2. The present invention provides an air compressor lubricating oil sampling device in which the sampling tube and the sampling bottle are detachably connected. Compared with the traditional operation of "directly inserting the sampling tube into the sampling bottle", the connection between the two is more stable, and the sampling tube is less likely to fall off during the sampling process, reducing the probability of lubricating oil spillage.

[0041] Example 1

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an air compressor lubricating oil sampling device includes a drain pipe 1, an air lift pump 2 and a valve 3 mounted on the drain pipe 1. The air lift pump 2 is characterized by being motorless and spark-free, suitable for explosion-proof requirements in natural gas production environments. The drain pipe 1 is used to connect to the oil tank of the air compressor. A sampling bottle 4 is detachably mounted at the end of the drain pipe 1. The sampling bottle 4 is made of transparent material, preferably glass, to facilitate observation of the lubricating oil level inside the sampling bottle 4. An exhaust pipe 42 is provided on the side of the sampling bottle 4. During the process of lubricating oil entering the sampling bottle 4, the air inside the sampling bottle 4 is discharged through the exhaust pipe 42. A plug 43 is provided at the opening of the exhaust pipe 42 to seal the exhaust pipe 42.

[0043] When in use, the air lift pump 2 is set on the oil tank of the air compressor, one end of the drain pipe 1 is inserted into the oil tank, and the other end of the drain pipe 1 is connected to the sampling bottle 4. The valve 3 on the drain pipe 1 is opened, and the air lift pump 2 is started. The air lift pump 2 draws the lubricating oil in the oil tank into the sampling bottle 4.

[0044] Specifically, a magnetic ring 5 is sleeved at the end of the drainage tube 1, and an iron ring 41 adapted to the magnetic ring 5 is provided at the mouth of the sampling bottle 4. The magnetic ring 5 and the iron ring 41 are attracted and connected, thereby realizing the detachable connection between the sampling bottle 4 and the drainage tube 1. On the one hand, it ensures the sealing during the sampling process and prevents the lubricating oil from spilling when entering the sampling bottle 4. On the other hand, it is easy to disassemble and assemble, and improves the sampling efficiency.

[0045] Furthermore, the magnetic ring 5 is an electromagnet, which gives it a stronger adsorption effect, preventing the sampling bottle 4 from accidentally falling off during the sampling process. At the same time, after the power is disconnected, the magnetic ring 5 is easier to separate from the sampling bottle 4, preventing the lubricating oil inside the sampling bottle 4 from being shaken and spilled during the separation process. The magnetic ring 5 is provided with an annular groove 51, and an elastic sealing ring 52 is provided in the annular groove 51. Under the adsorption of the electromagnet, the elastic sealing ring 52 in the annular groove 51 can be tightly attached to the surface of the iron ring 41, thereby improving the sealing performance between the magnetic ring 5 and the iron ring 41, and further preventing the lubricating oil from spilling during the sampling process.

[0046] Example 2

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, the difference between this embodiment and embodiment 1 is that it also includes a support plate 6 and a base 7. The support plate 6 is provided with holes 61 for installing the magnetic ring 5, and a plurality of columns 8 are provided between the base 7 and the support plate 6.

[0048] In this embodiment, by adding a support plate 6 and a base 7, the base 7 and the support plate 6 are connected by a column 8. The magnetic ring 5 is installed on the support plate 6, which realizes the support of the magnetic ring 5 and the drainage tube 1, ensuring that the position of the drainage tube 1 and the sampling bottle 4 is stable during the sampling process, without the need for manual support by personnel, making the operation simpler.

[0049] Furthermore, an annular limiting plate 62 is provided at the bottom of the hole 61, and the magnetic ring 5 is disposed on the annular limiting plate 62. The annular limiting plate 62 restricts the magnetic ring 5 located in the hole 61, preventing the magnetic ring 5 from falling out of the hole 61.

[0050] Furthermore, the base 7 is detachably equipped with an oil collection tray 9, which is located directly below the magnetic ring 5. After sampling, the residual lubricating oil in the drainage tube 1 easily falls into the oil collection tray 9, thus collecting the residual lubricating oil and preventing it from dripping into the environment and causing pollution. Moreover, the base 7 is equipped with a limiting groove 71 that matches the shape of the oil collection tray 9. The oil collection tray 9 is positioned in the limiting groove 71, enabling a detachable connection between the oil collection tray 9 and the base 7. The limiting groove 71 also guides the installation of the oil collection tray 9, allowing operators to accurately reinstall it in its original position after cleaning, ensuring that the oil collection tray 9 can accurately collect the residual lubricating oil from the drainage tube 1.

[0051] Example 3

[0052] like Figure 1 and Figure 4As shown, this embodiment provides an air compressor oil tank, including a tank body 10, and an air compressor lubricating oil sampling device as described in Embodiment 1 or Embodiment 2. A connecting plate is provided at the bottom of the air lift pump 2, and an mounting plate is welded to the top surface of the tank body 10. The connecting plate and the mounting plate are connected by bolts, and the drain pipe 1 extends into the tank body 10.

[0053] When it is necessary to sample the lubricating oil in the tank 10, connect the sampling bottle 4 to the end of the drainage tube 1, open the valve 3 on the drainage tube 1, and start the air lift pump 2 at the same time to draw the lubricating oil in the tank into the sampling bottle 4 through the air lift pump 2.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
