DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the utility model more clear and understandable, the utility model is further described in detail below in combination with the drawings and examples.

[0027] The specific implementation of the utility model is described in detail below in combination with specific examples.

[0028] Please refer to Figures 1 to 7The utility model discloses an antiwear hydraulic oil production is with feeding mechanism, antiwear hydraulic oil production is with feeding mechanism including the cover plate 1 for covering on the stirring tank, premixing cylinder 2, shunt cylinder 3, pressure valve group 4, shunt pipe fitting 5 and pressure material component 8, the disc core of cover plate 1 is equipped with mounting hole 1a, install the feed valve 11 on cover plate 1, in the application, cover plate 1 and the stirring tank for stirring base oil and additive are mutually matched, are fixedly installed on the stirring tank through screw, and the feed valve 11 is used to add base oil and part content more additive to the stirring tank.

[0029] In the embodiment of the utility model, please refer to Figures 1 to 7 The premixing cylinder 2 is coaxially arranged on the cover plate 1, the feed hopper 21 is arranged on the premixing cylinder 2, and the piston disc 6 is slidably connected in the premixing cylinder 2, the bottom of the piston disc 6 is provided with the stirring blade 7, specifically, the upper disc surface of the piston disc 6 is fixedly provided with the driving motor 71 through the rack, the driving motor 71 is fixedly provided with the rotating rod penetrating the piston disc 6 at the output end, the rotating rod is fixedly provided with a plurality of stirring blades 7 of the same specification, and the plurality of stirring blades 7 form a lower convex conical structure.

[0030] It should be noted that: a proper amount of base oil is added into the premixing cylinder 2 through the feed hopper 21, and then a small amount of additive (such as metal passivator) is added into the premixing cylinder 2 through the feed hopper 21, then the driving motor 71 is started to drive the stirring blade 7 to mix the base oil and the additive, so that the additive agglomerates can be broken down sufficiently, and the additive and the base oil form a uniform premixing liquid.

[0031] It should be noted that: in order to improve the mixing effect, a heating wire or a heating pipe can be arranged at the bottom of the premixing cylinder 2, so that the base oil is heated to be in a warm state, and the base oil is better mixed with the small amount of additive.

[0032] In the embodiment of the utility model, please refer to Figures 1 to 7The premixing cylinder 2 is equipped with a pressing component 8 for lifting the piston disc 6. The pressing component 8 includes a mounting bracket B81, which is fixedly mounted on the premixing cylinder 2. A hydraulic cylinder 82 is fixedly mounted on the inner top wall of the mounting bracket B81. A docking bracket 83 is fixedly mounted on the output end of the hydraulic cylinder 82 and is fixedly connected to the upper surface of the piston disc 6. A diverter cylinder 3 is fixedly mounted at the bottom of the premixing cylinder 2. The diverter cylinder 3 passes through the mounting hole 1a and extends to below the cover plate 1. A concave conical ring seat 31 is fixedly mounted inside the diverter cylinder 3. The upper part has a discharge hole 3a. The flow divider 3 is equipped with a pressure valve assembly 4. The pressure valve assembly 4 includes a mounting bracket A41. The mounting bracket A41 is fixedly installed at the bottom of the conical ring seat 31. A sliding rod 42 is inserted into the mounting bracket A41 and is slidably connected. A sealing ball 43 for sealing the discharge hole 3a is fixedly installed on the top of the sliding rod 42. A rod cap 44 is fixedly installed on the top of the sliding rod 42. A spring 45 is sleeved on the sliding rod 42. One end of the spring 45 is fixedly connected to the upper surface of the rod cap 44, and the other end of the spring 45 is fixedly connected to the lower surface of the mounting bracket A41.

[0033] It should be noted that in the initial state, the pressing component 8 does not apply downward thrust to the piston disc 6. At this time, the piston disc 6 is located above the feed hopper 21, and the sealing ball 43 descends and seals the discharge hole 3a under the action of the spring 45. Therefore, an appropriate amount of base oil and a small amount of additives can be stored in the premixing cylinder 2 for premixing (the amount of base oil and additives added is not higher than the interface between the feed hopper 21 and the premixing cylinder 2).

[0034] After the additives and base oil in the premixing cylinder 2 are mixed, the hydraulic cylinder 82 is activated to push the piston disc 6 down along the distributor cylinder 3. Thus, the piston disc 6 pushes the mixture in the premixing cylinder 2 down. When the liquid pressure is greater than the elastic force of the spring 45, the sealing ball 43 slides down along the mounting bracket A41 with the sliding rod 42 and compresses the spring 45, so that the sealing ball 43 no longer seals the discharge hole 3a. Therefore, the premixed liquid can be diverted through the distributor pipe 5 and injected into the mixing tank.

[0035] In this embodiment: since the multiple stirring blades 7 form a downwardly convex conical structure, and the upper surface of the conical ring seat 31 is a downwardly concave structure, when the piston disc 6 descends to the lowest point of the premixing cylinder 2, the stirring blades 7 forming the downwardly convex conical structure fall into the groove of the conical ring seat 31, which greatly reduces the amount of premixed liquid remaining.

[0036] In order to eliminate the potential risk of spring 45 rusting and losing its elasticity due to contact with coolant, spring 45 is made of stainless steel or titanium alloy to improve corrosion resistance. At the same time, a polytetrafluoroethylene (PTFE) coating is applied to the surface of spring 45 to enhance its rust prevention ability.

[0037] In the embodiments of this utility model, please refer toFigures 1 to 7 Figures 1 to 7 A diversion pipe fitting 5 is installed on the diversion cylinder 3 located below the cover plate 1. The diversion pipe fitting 5 includes branch pipes 51. Multiple branch pipes 51 are provided, and multiple branch pipes 51 are fixedly installed on the diversion cylinder 3 in a ring. A fixedly connected annular pipe 52 is mounted on the multiple branch pipes 51, and multiple annularly distributed nozzles 53 are fixedly installed on the annular pipe 52.

[0038] It should be noted that the premixed liquid enters the annular pipe 52 through the branch pipe 51 and is sprayed into the mixing tank by the nozzle 53 on the annular pipe 52, so that the premixed liquid can cover the annular area of ​​the mixing tank. Therefore, the contact area between the premixed liquid and the base oil in the mixing tank is greatly increased, ensuring that the trace additives are quickly and evenly integrated into the large system, and significantly improving the mixing uniformity and performance stability of the anti-wear hydraulic oil.

[0039] In addition, in this utility model, the hydraulic cylinder 82 is connected to a standard hydraulic system through an external pipeline to realize its extension and retraction control (the hydraulic cylinder 82 obtains power by connecting to an external hydraulic pump station through a pipeline, and switches the flow direction of hydraulic oil by operating the reversing valve on the pipeline, thereby controlling the extension or retraction of the telescopic rod). The specific settings of this hydraulic system are conventional technology in this field. Furthermore, the circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
