Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil production, in particular to a simple sampler for lubricating oil products. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used on various types of mechanical equipment to reduce friction and protect machinery and processed parts. With the rapid development of my country's national economy and the continuous improvement of equipment management level, the quality requirements for lubricating oil to ensure the reliable operation of equipment are becoming higher and higher. Therefore, the detection of lubricating oil is becoming more and more important.

[0003] Traditional oil samplers use negative pressure to extract samples through the process of pulling and drawing, so as to obtain samples. However, in the process of sampling, a large amount of force is required to complete the pulling and drawing process. If the force is too large or too small, it will affect the extraction amount and cannot accurately and stably realize the sampling pulling and drawing process. In view of the above problems, it is more important to design a simple sampler for lubricating oil products. Utility Model Content

[0004] The utility model aims to provide a simple sampler for lubricating oil products to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a simple sampler for lubricating oil products, comprising a sampling tube, a sampling bottle, a piston head, a piston sleeve shaft and a threaded rod, wherein the piston head, the piston sleeve shaft and the threaded rod are all arranged inside the sampling tube, the piston head is fixedly mounted on one end of the piston sleeve shaft, the other end of the piston sleeve shaft is provided with an internal thread on the inner wall, the piston sleeve shaft is threadedly connected to one end of the threaded rod through the internal thread, the other end of the threaded rod is fixedly connected to a sleeve, and the sleeve is mounted on the end cover.

[0006] Preferably, the end cover is fixedly mounted on one end of the sampling tube, and the outer side of the sleeve is connected to a handwheel via a connecting shaft, and the connecting shaft is fixedly connected to the handwheel.

[0007] Preferably, a nozzle is provided at the other end of the sampling tube, and a hose is sleeved on the nozzle.

[0008] Preferably, a sample outlet tube is extended from the surface of the sampling tube, and a sampling bottle is threadedly connected to the bottom of the sample outlet tube.

[0009] The beneficial effects of the utility model are:

[0010] 1. The simple sampler is provided with a hand wheel, a threaded rod, a piston sleeve shaft, a piston head, and a sampling tube. The piston head is completely fitted with the inner wall of the sampling tube without any dead angle, so as to avoid the contamination of the sample. The hand wheel is turned clockwise to make the threaded rod move in the piston sleeve shaft. At this time, the threaded rod is in a fixed position and only produces a rotating motion. At this time, the piston sleeve shaft is driven by the threaded rod and moves, so that the piston head can be pulled in the sampling tube. Since the hand wheel drives the threaded rod to control its steps, a more accurate and stable pulling process can be achieved, thereby solving the problem of unstable force and uncontrollable extraction amount.

[0011] 2. The simple sampler is provided with a nozzle, a hose and a sampling bottle. The hose is sleeved on the nozzle. The appropriate hose length can be selected according to the samples of different oil layers. Under the action of vacuum, the piston head moves to draw the oil into the sampling bottle, and then the hand wheel is turned counterclockwise to push the piston head back to balance the pressure in the sampling bottle with the outside world. Finally, the sampling bottle can be removed for testing. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0016] See also Figure 1 and Figure 2The utility model provides a technical solution: a simple sampler for lubricating oil products, including a sampling tube 1, a sampling bottle 2, a piston head 3, a piston sleeve shaft 4 and a threaded rod 5. The piston head 3, the piston sleeve shaft 4 and the threaded rod 5 are all arranged inside the sampling tube 1, the piston head 3 is fixedly installed at one end of the piston sleeve shaft 4, and the other end of the piston sleeve shaft 4 is provided with an internal thread on the inner side wall. It should be noted that the internal thread is only provided at the end of the piston sleeve shaft 4, the piston sleeve shaft 4 is threadedly connected to one end of the threaded rod 5 through the internal thread, and the other end of the threaded rod 5 is fixedly connected to the shaft sleeve 6, and the shaft sleeve 6 is installed on the end cover 7. Specifically, the interior of the piston sleeve shaft 4 can just be sleeved with the threaded rod 5.

[0017] Specifically, the end cover 7 is fixedly installed at one end of the sampling tube 1 , and the outer side of the shaft sleeve 6 is connected to the hand wheel 9 via the connecting shaft 8 , and the connecting shaft 8 is fixedly connected to the hand wheel 9 .

[0018] As a preferred solution, the hand wheel 9 is rotated clockwise to make the threaded rod 5 move in the piston sleeve shaft 4. At this time, the threaded rod 5 is stationary and only rotates, while the piston sleeve shaft 4 is driven by the threaded rod 5 and moves. It should be noted that the piston sleeve shaft 4 gradually swallows the threaded rod 5, so that the piston head 3 can be pulled in the sampling tube 1. Since the hand wheel 9 drives the threaded rod 5 to control its steps, a more accurate and stable pulling process can be achieved, thereby solving the problem of unstable force and uncontrollable extraction amount.

[0019] Specifically, a nozzle 10 is provided at the other end of the sampling tube 1, and a hose 11 is sleeved on the nozzle 10. The hose 11 can be selected to have a suitable length according to the samples of different oil layers.

[0020] Specifically, a sample outlet tube 12 is extended from the surface of the sampling tube 1, and a sampling bottle 2 is threadedly connected to the bottom of the sample outlet tube 12. Under the action of vacuum, the piston head 3 moves to draw the oil into the sampling bottle 2, and then the hand wheel 9 is turned counterclockwise to push the piston head 3 back, so that the pressure in the sampling bottle 2 is balanced with the external environment, and finally the sampling bottle 2 is removed for testing.

[0021] During the specific implementation of the utility model: firstly, the sampling bottle 2 is threadedly connected and fixed on the bottom of the sampling tube 12 on the sampling tube 1, and the hose 11 is sleeved on the nozzle 10, and the other end of the hose 11 goes deep into the oil drum, oil bottle, etc., and the threaded rod 5 is moved in the piston sleeve shaft 4 by rotating the hand wheel 9 clockwise. At this time, the threaded rod 5 is in a fixed position and only produces a rotating action, and the piston sleeve shaft 4 is driven by the threaded rod 5 and produces a moving process, so that the piston head 3 can be pulled in the sampling tube 1. Under the action of vacuum, the piston head 3 moves to draw the oil into the sampling bottle 2, and then the hand wheel 9 is rotated counterclockwise to push the piston head 3 back, so that the pressure in the sampling bottle 2 is balanced with the outside, and finally the sampling bottle 2 is removed for detection.
