Description

Technical Field

[0001] This utility model relates to the field of hydraulic control components, and in particular to a hydraulic control component with a high-strength wear-resistant plunger. Background Technology

[0002] The hydraulic control assembly of a plunger is a core component in a hydraulic system used to precisely control the movement of the plunger. It controls the unidirectional flow of hydraulic oil, ensuring that the plunger is locked or releases pressure at a specific position. In a plunger pump, the hydraulic control check valve can prevent oil backflow when the load decreases, maintaining system stability.

[0003] A split-type hydraulic thrust high-pressure sludge plunger pump hydraulic end device with Chinese patent number CN205401027U includes several independent single pump groups. Each single pump group includes a base and an inlet / outlet unit, a main plunger working unit, a secondary plunger working unit, and a control unit mounted on the base. The inlet / outlet unit includes an inlet port, a sludge inlet flange, an inlet valve assembly, an outlet port, and a check valve assembly. The control unit includes a control valve group and hydraulic pipelines. The control valve group is connected to the main plunger thrust cylinder and the secondary plunger thrust cylinder through the hydraulic pipelines and controls the movement of the main plunger assembly and the secondary plunger assembly.

[0004] The traditional single-filter structure in existing plunger pumps is difficult to simultaneously intercept ferromagnetic and non-magnetic impurities. Impurities can easily cause wear on the plunger and cylinder, scratches on the seals, shorten the pump's lifespan, and lead to frequent plunger pump failures. Especially in high-intensity working conditions such as mining and metallurgy, the frequency of downtime and maintenance caused by oil problems is high. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a hydraulic control assembly for a high-strength, wear-resistant plunger, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a hydraulic control component for a high-strength wear-resistant plunger, including a pretreatment oil tank, a secondary treatment oil tank fixedly connected to the lower end of the pretreatment oil tank, a honeycomb defoaming net fixedly connected to the lower end of the pretreatment oil tank, the honeycomb defoaming net being located between the pretreatment oil tank and the secondary treatment oil tank, the outer end of the honeycomb defoaming net having multiple filter ring holes evenly distributed among them, a vertical conical diverting column fixedly connected to the middle of the upper end of the honeycomb defoaming net, a strong magnetic adsorption layer fixedly connected to both the vertical conical diverting column and the inner layer of the honeycomb defoaming net, a liquid guiding thread provided at the outer end of the vertical conical diverting column, a sealing top cover fixedly connected to the upper end of the pretreatment oil tank, a liquid infusion pipe interface fixedly connected to the middle of the upper end of the sealing top cover, and an inverted conical guide frame fixedly connected to the upper side of the inner end of the pretreatment oil tank.

[0007] As a further technical solution of this utility model, the lower end of the inverted conical guide frame and the vertical conical diverter column correspond to each other, and a rigid spiral baffle is fixedly connected to the middle of the inner end of the secondary treatment tank.

[0008] As a further technical solution of this utility model, the upper end of the rigid spiral baffle is the top oil return area, and the lower end of the rigid spiral baffle is the bottom oil suction area.

[0009] As a further technical solution of this utility model, the top oil return area and the bottom oil suction area are respectively set on the upper and lower sides of the secondary treatment oil tank, and a hollow interlayer is opened on the outer side of the secondary treatment oil tank.

[0010] As a further technical solution of this utility model, a heating wire is fixedly connected to the inner end of the hollow sandwich layer, and a bottom sedimentation bin is fixedly connected to the lower end of the secondary treatment oil tank.

[0011] As a further technical solution of this utility model, a discharge valve is installed at the lower end of the bottom sedimentation tank, and an oil tank pump is connected to the external secondary treatment oil tank.

[0012] As a further technical solution of this utility model, the pretreatment oil tank is filled with a certain amount of oil, and the oil flows through the pretreatment oil tank, the honeycomb defoaming net and the secondary treatment oil tank in sequence.

[0013] This invention provides a hydraulic control assembly for a high-strength, wear-resistant plunger, which has the following advantages compared with the prior art:

[0014] This design utilizes a high-strength, wear-resistant plunger hydraulic control assembly. The system employs a pre-treatment tank and a secondary treatment tank for tiered treatment, providing clean oil to the plunger system. External return oil or new oil enters the pre-treatment tank via the inlet pipe interface on the sealed top cover. It first contacts the inverted conical guide frame, which guides the oil towards the center, preventing splashing and directing it towards the vertical conical diverter column. The oil is dispersed upon impact with the column, forming a spiral flow through the guide threads. As it flows past the vertical conical diverter column and the strong magnetic adsorption layer within the honeycomb defoaming mesh, its ferromagnetic properties are utilized. Impurities are adsorbed, and then the oil permeates the honeycomb defoaming net, defoaming and intercepting non-magnetic impurities through the filter ring holes, completing secondary purification. After filtration, the oil enters the secondary treatment tank and flows spirally along the rigid spiral baffle. It flows steadily from the top of the return oil area to the bottom of the suction oil area, and fine impurities are further precipitated. At low temperature, the heating wire in the hollow jacket heats the oil to ensure suitable viscosity. The precipitated impurities fall into the bottom sedimentation tank and can be discharged periodically through the discharge valve. Finally, the clean oil is transported to the plunger system by the oil tank pump. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a hydraulic control component technical solution for a high-strength wear-resistant plunger: it includes a pretreatment oil tank 1, a secondary treatment oil tank 10 fixedly connected to the lower end of the pretreatment oil tank 1, a honeycomb defoaming net 7 fixedly connected to the lower end of the pretreatment oil tank 1, the honeycomb defoaming net 7 being located between the pretreatment oil tank 1 and the secondary treatment oil tank 10, the outer end of the honeycomb defoaming net 7 having multiple filter ring holes 8, the multiple filter ring holes 8 being evenly distributed, the upper middle part of the honeycomb defoaming net 7 being fixedly connected to a conical diverting column 5, both the conical diverting column 5 and the inner layer of the honeycomb defoaming net 7 being fixedly connected to a strong magnetic adsorption layer 19, the outer end of the conical diverting column 5 having a liquid guiding thread 6, the upper end of the pretreatment oil tank 1 being fixedly connected to a sealing top cover 2, the upper middle part of the sealing top cover 2 being fixedly connected to a liquid inlet 3, and the upper inner side of the pretreatment oil tank 1 being fixedly connected to an inverted conical guide frame 4.

[0023] Please see Figure 2The lower end of the inverted conical guide frame 4 and the vertical conical diverter column 5 correspond to each other. A rigid spiral baffle 11 is fixedly connected to the middle of the inner end of the secondary treatment oil tank 10. The upper end of the rigid spiral baffle 11 is the oil return top area 18, and the lower end of the rigid spiral baffle 11 is the oil suction bottom area 12. The oil return top area 18 and the oil suction bottom area 12 are respectively set on the upper and lower sides of the secondary treatment oil tank 10.

[0024] The filtered oil enters the secondary treatment tank 10 and flows through the rigid spiral baffle 11. The rigid spiral baffle 11 divides the interior of the secondary treatment tank 10 into two areas: the upper part is the return oil top area 18 and the lower part is the oil suction bottom area 12. The oil moves in a spiral motion along the guidance of the rigid spiral baffle 11, and the flow rate gradually stabilizes.

[0025] Please see Figure 2-4 The secondary treatment oil tank 10 has a hollow jacket 9 on its outer side. The inner end of the hollow jacket 9 is fixedly connected to a heating wire 14, which can be a single-ended stainless steel heating tube, model DRX-1.5KW-220V. The lower end of the secondary treatment oil tank 10 is fixedly connected to a bottom sedimentation chamber 16. The lower end of the bottom sedimentation chamber 16 is equipped with a discharge valve 17. The secondary treatment oil tank 10 is connected to an oil tank pump 15. The pretreatment oil tank 1 is filled with a certain amount of oil. The oil flows through the pretreatment oil tank 1, the honeycomb defoaming net 7, and the inside and outside of the secondary treatment oil tank 10.

[0026] Gravity causes unfiltered fine impurities to settle further, accumulating at the bottom of the oil tank. If the oil temperature is too low, the heating wire 14 inside the hollow jacket 9 on the outside of the secondary treatment oil tank 10 can be activated to heat the oil by conducting heat through the tank wall, thus preventing excessive viscosity from affecting fluidity. The process automatically stops once the temperature reaches the target, ensuring that the oil is within the optimal working viscosity range. The settled impurities eventually fall into the bottom sedimentation chamber 16 at the bottom of the secondary treatment oil tank 10 and can be discharged by periodically opening the discharge valve 17 to prevent impurities from mixing back into the oil.

[0027] The working principle of this utility model is as follows: This solution provides a clean and stable oil supply to the plunger system through the graded treatment of the pretreatment oil tank 1 and the secondary treatment oil tank 10, combined with multi-functionality. External return oil or newly added oil enters the pretreatment oil tank 1 through the infusion pipe interface 3 at the upper end of the sealed top cover 2. The oil first contacts the inverted conical guide frame 4 on the upper side of the inner end of the pretreatment oil tank 1. The inverted conical guide frame 4 uses its conical structure to converge the oil towards the center, avoiding direct impact of the oil on the inner wall of the tank and preventing splashing. At the same time, it guides the oil to flow downwards and precisely correspond to the vertical conical diversion column 5. The oil, guided by the inverted conical guide frame 4, directly impacts the vertical conical diversion column 5 at the upper center of the honeycomb defoaming net 7. The vertical conical diversion column 5 disperses the concentrated oil to all sides through its conical surface. Combined with the spiral groove of the outer liquid guiding thread 6, the oil forms a spiral flow, prolonging the residence time of the oil in the pretreatment area. During this process, the oil needs to flow through the vertical conical diversion column 5 and the strong magnetic adsorption layer 19 inside the honeycomb defoaming net 7. The magnetic field generated will adsorb the ferromagnetic impurities mixed in the oil, achieving preliminary impurity removal. The oil that has completed magnetic impurity removal continues to penetrate downwards into the honeycomb net. The honeycomb defoaming net 7, with its porous structure, cuts air bubbles through the filter ring holes 8, eliminating air in the oil and preventing subsequent cavitation. Simultaneously, the filter ring holes 8 intercept and filter non-magnetic impurities, achieving secondary purification of the oil. The filtered oil enters the secondary treatment tank 10 and flows through the rigid spiral baffle 11. The rigid spiral baffle 11 divides the interior of the secondary treatment tank 10 into upper and lower regions: the upper part is the return oil top region 18, and the lower part is the oil suction bottom region 12. The oil moves in a spiral motion guided by the rigid spiral baffle 11, with a flow rate... As the oil gradually stabilizes, gravity causes unfiltered fine impurities to settle further, accumulating at the bottom of the tank. If the oil temperature is too low, the heating wire 14 inside the hollow jacket 9 on the outside of the secondary treatment tank 10 can be activated to heat the oil, raising the temperature through heat conduction via the tank wall. This prevents excessive viscosity from affecting fluidity. Once the temperature reaches the target, the process automatically stops, ensuring the oil is within its optimal working viscosity range. The settled impurities eventually fall into the bottom sedimentation chamber 16 at the bottom of the secondary treatment tank 10 and can be discharged periodically by opening the discharge valve 17 to prevent impurities from mixing back into the oil.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
