Description

Technical Field

[0001] The present application relates to the technical field of pump detection equipment, and in particular to a self-priming oil quality analyzer for a pump. Background Art

[0002] Some pumps such as water pumps or impellers used in water have a working environment in liquid and there is oil in the oil chamber of the pump. During the assembly process, it is necessary to ensure the sealing of the oil chamber to prevent liquid such as water from entering.

[0003] When water is mixed into the lubricating oil, the oil and water will emulsify under high-speed operation. The oil will turn white after emulsification, and its performance will be greatly reduced after emulsification, which will cause serious damage to the parts in the pump and reduce its service life.

[0004] Therefore, for pumps that are in a liquid environment for a long time, it is necessary to frequently check whether the oil in the oil chamber is mixed with water. However, it is too cumbersome and inconvenient to pour out the oil in the oil chamber through the drain port for inspection every time. Utility Model Content

[0005] In order to facilitate the detection of oil mixed in the oil chamber of a pump, the present application provides a self-priming oil quality analyzer for a pump.

[0006] The present application provides a pump self-priming oil quality analyzer, which adopts the following technical solution: a pump self-priming oil quality analyzer, comprising a sampling cylinder, to which an extraction machine is detachably connected, and the extraction machine has a sampling tube for inserting into an oil chamber;

[0008] By adopting the above technical solution, the sampling tube is first extended into the oil chamber through the sampling cylinder, and the liquid in the oil chamber is extracted into the sampling cylinder. At the same time, the analysis rod in the sampling cylinder can detect the conductivity of the overall sample through the first detection metal rod and the second detection metal rod. Since the oil-water ratio in the mixture is uneven, the distance can be changed by adjusting the section to obtain a more accurate detection result.

[0009] Preferably, the extractor is snap-fitted into a housing, and the housing is detachably connected to the sampling barrel.

[0010] Preferably, the housing has a clamping plate, the inner side of the clamping plate has a mounting groove, a clamping sheet is embedded and fixed in the mounting groove, and the inner wall of the mounting groove has a clamping point embedded in the side wall of the clamping sheet.

[0011] Preferably, the analysis rod is provided with a lifting section, and the lifting section includes a fixing portion, an adjusting sleeve, and a threaded column;

[0012] The fixing part is detachably connected to the sampling tube, the adjusting sleeve is rotatably connected to the end of the fixing part, the threaded column is fixedly connected to the middle of the adjusting sleeve, the analysis rod is circumferentially limited and axially slidably connected to the fixing part, and the threaded column is threadedly connected to the middle of the analysis rod.

[0013] Preferably, the upper portion of the adjustment section is rotatably disposed on the end portion of the second detection metal rod, and the lower end of the adjustment end is inclined.

[0014] Preferably, the upper end of the adjustment section is a hollow structure, a plurality of protrusions are circumferentially arranged on the inner wall, and the outer wall of the second detection metal rod has an annular groove that matches the protrusions.

[0015] Preferably, the annular groove has a guide groove corresponding to the convex points one by one along the axial direction at one end of the annular groove facing the second detection metal rod, and a plurality of grooves cooperating with the convex points are arranged in the circumferential direction in the annular groove.

[0016] Preferably, the upper end of the adjusting section is a hollow structure, and the outer wall of the adjusting section has a recessed portion for pressing against the outer wall of the second detection metal rod.

[0017] In summary, the present application includes at least one of the following beneficial technical effects: the sampling tube extends into the oil chamber to draw the liquid in the oil chamber into the sampling tube, and at the same time, the analysis rod in the sampling tube can detect the conductivity of the overall sample through the first detection metal rod and the second detection metal rod. Since the oil-water ratio in the mixture is uneven, the distance can be changed by adjusting the section to obtain a more accurate detection result. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings. Example

[0025] A self-priming oil quality analyzer for pumps, Figure 1 , including a sampling barrel 100, to which an extractor 110 is detachably connected. In this embodiment, the extractor 110 is a liquid pump, and the extractor 110 has a sampling tube 111 for inserting into the oil chamber. The extractor 110 is snap-fitted in a housing 113, and the housing 113 is detachably connected to the sampling barrel 100.

[0026] Reference Figure 1 , Figure 2 The upper side of the housing 113 is open, and the extractor 110 is placed in it as a whole. Since the extractor 110 may shake during operation, a rubber layer 114 is provided inside the housing 113, which can increase the friction with the extractor 110 and reduce the impact of the shaking on the whole. The sampling tube 111 passes through the side wall of the housing 113.

[0027] The housing 113 has a clamping plate 120, which is clamped on the outer wall of the sampling tube 100. Since the inner side of the clamping plate 120 has a mounting groove 121, a rubber sheet 122 is embedded and fixed in the mounting groove 121, and the inner wall of the mounting groove 121 has a clamping point 123 embedded in the side wall of the rubber sheet 122. The entire rubber sheet 122 can be clamped in the mounting groove 121, but it is also convenient for subsequent replacement. It is worth noting that the rubber sheet 122 protrudes outward in the mounting groove 121, so that it can be well pressed against the outer wall of the sampling tube 100.

[0028] Reference Figure 1 , Figure 3The sampling tube 100 can also be detachably connected with an analysis rod 130, which includes a first detection metal rod 131 and a second detection metal rod 132, wherein an adjustment section 133 is rotatably provided at the end of the second detection metal rod 132, for changing the distance between the second detection metal rod 131 and the first detection metal rod 131. In general, the adjustment section 133 is a straight portion at the upper section and an inclined portion at the lower section. The upper end of the adjustment section 133 is a hollow structure, which is used to be sleeved on the outer wall of the second detection metal rod 132. When the whole is rotated, the distance between the inclined end and the end of the first detection metal rod 131 will change, so that the detection accuracy can be adjusted.

[0029] Reference Figure 3 , Figure 4 In this embodiment, a plurality of protrusions 134 are arranged circumferentially on the inner wall of the hollow part of the adjustment section 133, and an annular groove 135 is provided on the outer wall of the second detection metal rod 132 to cooperate with the protrusion 134. In addition, a plurality of grooves 136 to cooperate with the protrusion 134 are evenly distributed circumferentially on the annular groove 135. When rotating, the protrusion 134 can be snapped into different grooves 136, and can be fixed circumferentially while rotating. In order to achieve this function, the protrusion 134 in this embodiment is a hollow metal protrusion 134, so that it has a certain deformation ability, and can be easily separated from and embedded in the groove 136 in the circumferential direction.

[0030] At the same time, in order to be installed on the second detection metal rod 132, a guide groove 137 corresponding to the convex point 134 is provided in the axial direction at one end of the annular groove 135 facing the second detection metal rod 132. During installation, the adjustment section 133 is sleeved on the second detection metal rod 132 through the guide groove 137. It is worth noting that the guide groove 137 is staggered in the axial direction with the groove 136 in the circumferential direction. When the adjustment section 133 is rotating, it will not fall out of the guide groove 137, and it is stable in use.

[0031] Reference Figure 1 , and because the liquid level in the sampling tube 100 varies according to the type of the pump, the amount of oil sample taken out will also be different, so in this embodiment, the analysis rod 130 itself is used as a function that can be adjusted in the length direction. Specifically, a lifting section is provided on the analysis rod 130, and the lifting section includes a fixing portion 140, an adjusting sleeve 142, and a threaded column 143.

[0032] The fixing part 140 is detachably connected to the sampling tube 100. The fixing part 140 is clamped on the sampling tube 100 by a clip 141. Since the fixing part 140 is smaller in volume than the extraction machine 110, only the clip 141 is needed to fix it. The adjustment sleeve 142 is rotatably connected to the end of the fixing part 140. The threaded column 143 is fixedly connected to the middle of the adjustment sleeve 142. The analysis rod 130 is circumferentially limited and axially slidably connected to the fixing part 140. Specifically, the end of the analysis rod 130 is a rectangular parallelepiped, and the fixing part 140 is also a rectangular groove. At the same time, the threaded column 143 is threadedly connected to the middle of the analysis rod 130 (the threaded mating surface is not shown in the figure), and the threaded column 143 is coaxially arranged with the analysis rod 130.

[0033] The implementation principle of the embodiment of the present application is: the outer shell 113 is clamped on the sampling tube 100, and the oil in the oil chamber is extracted into the sampling tube 100 through the sampling tube 111. At this time, for the liquid level of the oil sample, the adjustment sleeve 142 is rotated, and the threaded column 143 will rotate synchronously. However, since the end of the analysis rod 130 is limited in the fixed part 140, it will move and adjust along the axial direction relative to it, thereby realizing the position adjustment of the first detection metal rod 131 and the second detection metal rod 132 on the lower side.

[0034] When the detection accuracy needs to be adjusted, the adjustment section 133 is rotated so that the protrusion 134 is circumferentially shifted to other grooves 136, thereby achieving end movement of the adjustment section 133 and changing the distance between the ends. Example

[0035] The difference from Example 1 is that, referring to Figure 5 The outer wall of the adjustment section 133 has a recessed portion for pressing against the outer wall of the second detection metal rod 132. In other words, the hollow portion of the adjustment section 133 is non-circular, and its elliptical shape can be better snapped onto the second detection metal rod 132, thereby achieving fixation.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
