Description

Technical Field

[0001] This utility model relates to the field of servo oil tank technology, and specifically to a centralized oil supply servo oil tank structure. Background Technology

[0002] In many fields of modern industry, such as machinery manufacturing, automotive industry, aerospace and various automated production lines, hydraulic systems are widely used as a key means of power transmission and control. Centralized oil supply servo tanks are an indispensable and important component of hydraulic systems, and their performance and structural rationality are directly related to the stable operation, reliability and service life of the entire hydraulic system.

[0003] Traditional hydraulic tanks are often simply designed, typically only having the basic function of storing hydraulic fluid. In some high-speed hydraulic equipment, due to the lack of effective internal structural design, a negative pressure environment can quickly form inside the tank. To avoid this, vent holes are usually installed on the tank. While vent holes can prevent negative pressure, the exchange of gases between the inside and outside of the tank means that air will directly contact the hydraulic fluid over a large area. Oxygen from the air will inevitably dissolve into the hydraulic fluid, triggering an oxidation reaction. As the oxidation reaction continues, the hydraulic fluid will gradually deteriorate, producing harmful substances such as acidic substances, colloids, and sediments. Furthermore, oxidation can severely affect the lubrication performance, viscosity characteristics, and wear resistance of the hydraulic fluid, leading to increased friction in the hydraulic system, decreased precision in the fit between components, slower system response, and reduced control accuracy.

[0004] To address the aforementioned issues, this application proposes a centralized oil supply servo tank structure. Utility Model Content

[0007] The partition plate is fixedly connected to the baffle through the second threaded groove. The bottom of the block is in contact with the top of the baffle. By setting the baffle, the block is blocked, thus avoiding affecting the sealing of the second threaded groove.

[0008] The fixing component includes a threaded rod threadedly connected to the outer wall of the oil tank body. The partition plate has an insertion hole on the side near the threaded rod. A spring is fixedly connected to the partition plate through the insertion hole. A round block is fixedly connected to one end of the spring. One end of the threaded rod is in contact with the side of the round block away from the spring. By setting the fixing component, the partition plate is fixed, preventing some oil from falling onto the partition plate when oil is introduced into the oil tank body.

[0009] The top of the fuel tank body is provided with a fixing hole, and a filter plate is movably connected to the fuel tank body through the fixing hole. The bottom of the filter plate is attached to the top of the fuel tank body. By setting the fixing hole and the filter plate, the inside of the fuel tank body is protected, and dust is prevented from entering the fuel tank body and affecting the fuel inside the fuel tank body.

[0010] The fuel tank body is equipped with a viewing window, which allows for observation of the fuel inside the tank, thus facilitating maintenance by the user.

[0011] A connecting pipe is fixedly connected to the partition plate, and a round rod is rotatably connected to the inner wall of the connecting pipe.

[0012] A shield is fixedly connected to the top of the fuel tank body. The shield is located directly above the filter plate. By setting up the shield, the filter plate is protected, and water entering the fuel tank body is prevented from affecting the oil inside the fuel tank body.

[0013] The beneficial effects of this utility model are:

[0014] When the operator uses the fuel tank, the fuel inside the tank is rapidly pumped out. At this time, the partition plate will fall down as the fuel inside the tank decreases. When the partition plate falls, the fuel tank will also allow air to enter through the vent to avoid affecting the pressure balance inside the fuel tank. At the same time, when gas enters the fuel tank, the partition plate will separate the gas from the fuel inside the tank as much as possible to prevent the fuel inside the tank from oxidizing.

[0015] By setting a fixing component, the partition plate is fixed. When it is necessary to inject oil into the tank body, the threaded rod can be rotated to insert into the insertion hole of the partition plate, thereby fixing the partition plate and preventing some oil from falling onto the partition plate when oil is injected into the tank body.

[0032] Reference Figure 2 and Figure 3 The oil tank body 2 is provided with a viewing window 8, which is used to observe the oil inside the oil tank body 2. When the oil inside the oil tank body 2 appears above the partition plate 301, it can be observed through the viewing window 8, which facilitates its maintenance.

The cooperation between the connecting pipe 9 and the round rod 10 enables the partition plate 301 to slide down conveniently. When the partition plate 301 moves down and up, the friction between the partition plate 301 and the inside of the oil tank body 2 is reduced, thereby avoiding affecting the downward and upward movement of the partition plate 301.

[0034] Reference Figure 1 A shield 11 is fixedly connected to the top of the fuel tank body 2. The shield 11 is located directly above the filter plate 7. The shield 11 is used to protect the filter plate 7 and prevent rainwater from falling into the interior of the fuel tank body 2 through the filter plate 7 when the fuel tank is used in the outside, thereby preventing water from entering the fuel tank body 2 and affecting the oil inside the fuel tank body 2.

[0035] Working principle:

[0036] This centralized oil supply servo tank structure involves the rapid extraction of oil from the tank body 2 during use. As the oil is rapidly extracted, the partition plate 301 descends, allowing air to enter the tank body 2 through the vent 5. This prevents disruption of the internal pressure balance. Simultaneously, the partition plate 301 separates the gas from the oil as much as possible, preventing oxidation of the oil. However, the oil inside the tank body 2 may become damaged over prolonged use. In such cases, the operator will clean the oil. To replace the oil, after the oil flows out, the operator rotates the fixing pipe 303 to remove it from the oil tank body 2. After removing the fixing pipe 303, the operator pulls the partition plate 301 to the top. At this time, the threaded rod 401 can be rotated to insert into the insertion hole 402 of the partition plate 301, thereby fixing the partition plate 301. This prevents some oil from falling above the partition plate 301 when oil is introduced into the oil tank body 2. After the partition plate 301 is fixed, the operator rotates the limiting rod 306 and the plug 308 through the fixing pipe 303, thereby removing the plug 308 from the area of ​​the partition plate 301, thus allowing liquid to enter the oil tank body 2.
