Description

Technical Field

[0001] The utility model relates to the technical field of anti-wear hydraulic lubricating oil, in particular to a viscosity detection device for anti-wear hydraulic lubricating oil. Background Technique

[0002] Anti-wear hydraulic oil is a special lubricating oil, which is made of a base oil added with special additives such as anti-wear agents and preservatives. This oil has strong anti-wear and anti-rust capabilities and can effectively extend the service life of the hydraulic system. A variety of high-efficiency anti-wear agents and lubricants are added to the anti-wear hydraulic oil. These additives can form a protective film on the metal surface, reduce friction and wear, and thus protect the moving parts inside the hydraulic system.

[0003] During the production process of anti-wear hydraulic oil, its viscosity needs to be detected. Currently, a kinematic viscosity measuring instrument is mostly used for detection. Before testing, the sample needs to be drawn into the capillary tube. Currently, the operation is to block one end of the capillary tube with a finger, and then flatten the rubber bulb and connect it to the capillary tube. The sample is drawn into the capillary tube through the suction of the rubber bulb. For the above operation, a single finger is required to block the capillary tube. During this period, the movement of the hand is restricted and a slight movement will cause air leakage and affect the adsorption effect. Moreover, the suction and the air extrusion of the rubber bulb are certain. For samples with relatively high viscosity, they cannot be quickly and effectively sucked. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 , 2 , as shown in Figures 3, 4, 5, 6, 7, the present utility model provides a technical solution: an anti-wear hydraulic lubricating oil viscosity detection device, comprising: a support platform 1 provided with leveling screws at the bottom; a glass cylinder 4 is installed on the top of the support platform 1, a top cover 5 is detachably installed on the top of the glass cylinder 4, a stirring part and a placement hole are provided in the middle of the top cover 5, a cover plate 22 is installed in the placement hole, a capillary tube 9 is detachably installed in the middle of the cover plate 22, and one end of the capillary tube 9 is fixedly connected with an adjustable plug for adjusting the closing of one end of the capillary tube 9; a negative pressure suction part for evacuating the inside of the capillary tube 9, the negative pressure suction part comprising a tube barrel 10 and a piston rod 12 slidably arranged inside the tube barrel 10, a first one-way valve 16 for discharging the air inside the tube barrel 10 is installed on one side of the end of the tube barrel 10, and a second one-way valve 17 for sucking air into the inside of the tube barrel 10 is installed at the end of the tube barrel 10.

[0027] It should be noted that in the present utility model, the instrument is placed on a horizontal workbench, and an appropriate amount of water or other medium is injected into the glass cylinder 4 so that the liquid level is about 20 millimeters away from the cylinder edge; the adjustable plug cover is adjusted so that the large opening of the capillary 9 is blocked, and then the negative pressure suction part is connected to the side of the capillary 9 through a hose. By pulling and pushing the piston rod 12, air enters the tube barrel 10 through the second one-way valve 17 and is discharged through the first one-way valve 16, exhausting the air inside the tube barrel 10 and the capillary 9. Under the action of negative pressure, a sample of anti-wear hydraulic lubricating oil is inhaled into the capillary 9 according to national standards. The capillary 9 is installed on the cover plate 22 and placed into the glass cylinder 4 through the corresponding holes; when the capillary is not parallel to the plumb line, it is adjusted through the screws on the cover plate 22; the temperature control switch is turned on to make the temperature in the bathtub reach and maintain the set constant temperature; when the liquid level just reaches the upper scale line of the capillary viscometer 9, timing starts, such as clicking the corresponding timer; when the liquid level just flows to the lower scale line of the capillary viscometer, timing stops, and the corresponding timer is clicked again; the above steps are repeated to complete all measurements according to the set number of experiments.

[0028] Please refer to Figure 1 As shown, a control box is fixedly connected to the top of the support table 1, a control panel 2 is fixedly connected to the outside of the control box, and a temperature display 3 is fixedly connected to the top of the support table 1. The temperature display 3 is electrically connected to the temperature sensor on the outside of the glass cylinder 4.

[0029] It should be noted that in the present utility model, the temperature display 3 displays the temperature detected by the temperature sensor of the glass cylinder 4. Inside the control box, there are a timing and data acquisition module, a data processing module, and a result calculation and storage module; the instrument performs second timing by outputting a standard 0.1-second pulse through the CPU, and records the time for the liquid to flow through a calibrated glass capillary viscometer under gravity; this data is accurately captured by the sensor and circuit and transmitted to the microprocessor; the microprocessor uses the built-in algorithm to process the collected time data; this processing process is based on the basic principle of kinematic viscosity measurement, that is, the product of the capillary constant of the viscometer and the flow time is the kinematic viscosity of the measured liquid at this temperature; for each experiment, the instrument calculates the corresponding kinematic viscosity value according to the recorded flow time and the known capillary constant; when the set number of experiments is completed (such as 4 times required by national standards), the instrument automatically calculates the arithmetic mean value of the kinematic viscosity value; this arithmetic mean value is regarded as the final result and is stored in the memory of the instrument for subsequent viewing or printing.

[0030] Please refer to Figure 2 As shown, the stirring part includes a driving motor 6 fixedly connected to the top of the top cover 5. The output end of the driving motor 6 is fixedly connected to a stirring rod 8, the stirring rod 8 extends into the glass cylinder 4, and an electric heating tube 7 for constant temperature heating is installed at the bottom of the top cover 5.

[0031] It should be noted that when the electric heating tube 7 of the present utility model heats the inside of the glass cylinder 4, the driving motor 6 drives the stirring rod 8 to rotate, so as to mix and stir the upper and lower water levels inside the glass cylinder 4, so that the internal temperature can quickly and evenly reach the specified value.

[0032] Please refer to Figure 7 As shown, a fixed clamping plate 20 is fixedly connected to the top of the cover plate 22. A sliding rod is slidably connected inside the fixed clamping plate 20. One end of the sliding rod is fixedly connected to a sliding clamping plate 14, and the other end of the sliding rod is fixedly connected to a push plate. A second spring 21 is sleeved on the outer side of the sliding rod and between the push plate and the fixed clamping plate 20.

[0033] It should be noted that when the capillary 9 of the present utility model is cooperatively installed with the cover plate 22, by pressing the push plate by hand, while the push plate compresses the second spring 21, the fixed clamping plate 20 and the sliding clamping plate 14 are separated through the sliding rod. Then, the small-mouth tube of the capillary 9 is penetrated from the bottom of the cover plate 22 to between the sliding clamping plate 14 and the fixed clamping plate 20. Then, the force applied to the push plate is released. Under the action of the second spring 21, the sliding clamping plate 14 and the fixed clamping plate 20 clamp the capillary 9.

[0034] Please refer to Figure 2 、 3 As shown in FIGS. 4, the adjustable plug cap includes a sealing plug 18 installed at one end of the capillary 9. A rotating cover 19 is rotatably connected to the top of the sealing plug 18. Vent holes 13 are provided in the middle parts of both the rotating cover 19 and the sealing plug 18.

[0035] It should be noted that the capillary 9 of the present utility model has a U-shaped structure, with a large-mouth tube and a small-mouth tube at both ends respectively. The adjustable plug cap is installed inside the large-mouth tube. Two liquid storage balls are provided in the middle of the small-mouth tube. During use, the anti-wear hydraulic lubricating oil sample needs to be sucked into the liquid storage balls. At this time, by rotating the rotating cover 19, the vent holes 13 in the middle parts of the rotating cover 19 and the sealing plug 18 are misaligned with each other. Since both are made of rubber material, sealing is achieved in this way. When ventilation at the end needs to be ensured, rotate the rotating cover 19 so that the upper and lower vent holes 13 correspond to achieve ventilation. In this way, when pumping liquid, there is no need to block it with fingers, and the operation is more convenient.

[0036] Please refer to Figure 5 、 6 As shown in FIGS., a filter plate 15 is fixedly connected inside the tube barrel 10. A first spring 11 is installed between the filter plate 15 and the piston rod 12

[0037] It should be noted that when the anti-wear hydraulic lubricating oil sample is sucked into the liquid storage ball of the present utility model, the vent hole 13 is rotated to block one end of the large-mouth pipe, and then the end of the tube barrel 10 is connected to the side interface of the large-mouth pipe through a hose. One end of the small-mouth pipe is inserted into the sample, and the piston rod 12 is pushed to move inward. The air inside the tube barrel 10 is discharged from the first one-way valve 16, and during this period, the first spring 11 is compressed. When no pressure is applied to the piston rod 12, the first spring 11 drives the piston rod 12 to reset. When the piston rod 12 resets, the air inside the capillary 9 is pumped out through the hose, so that a negative pressure is formed inside the capillary 9, causing the sample to enter the liquid storage ball. After the suction is completed, the capillary 9 is installed at the middle part of the cover plate 22 downward.
