Detailed implementation manners

[0026] 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 of 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.

[0027] The present utility model provides an energy-saving servo hydraulic pump station as Figures 1-5 shown, including a base 2 and a plurality of pump bodies 6 installed on the base 2;

[0028] The outer wall of the upper end of the base 2 is fixedly connected near the right side with a fuel tank 18;

[0029] The outer wall of the upper end of the fuel tank 18 is provided with a motor 1;

[0030] A pressure measuring hose 16 is provided between each of the multiple pump bodies 6 and the fuel tank 18. A plurality of oil discharge ports a13 are equidistantly arranged on the outer wall at the rear end of the fuel tank 18 to output the oil to the designated equipment. During hydraulic operation, the motor 1 is started to drive the pump body 6 to work. The pump body 6 sucks hydraulic oil from the fuel tank 18 and conveys it to the hydraulic system through pressurization. At the same time, the pressure measuring hose 16 monitors the system pressure. According to the pressure feedback by the pressure measuring hose 16, the control system can adjust the operating state of the motor 1 in a timely manner, thereby improving the energy utilization efficiency. The oil discharge port a13 conveys the pressurized hydraulic oil to the hydraulic actuator connected to the pump station to achieve effective energy transfer. The used hydraulic oil flows back to the fuel tank 18 through the oil return port 14 to realize the recycling of the hydraulic oil;

[0031] Inside the outer wall at the right end of the fuel tank 18, a guiding pipe 21 is fixedly connected. Inside the circular outer wall at the upper end of the guiding pipe 21, a liquid inlet 22 that penetrates up and down is opened to guide the oil to enter. Near the left side of the circular outer wall at the lower end of the guiding pipe 21, a sampling pipe 25 is fixedly connected to guide the guided oil outwards. When it is necessary to sample and detect the oil, the oil inside the fuel tank 18 can be guided into the sampling pipe 25 through the liquid inlet 22 opened on the guiding pipe 21. And a sampling pipe 25 or a corresponding container is placed at one end of the sampling pipe 25 in advance. After receiving the sampled oil, subsequent analysis of the oil can be carried out.

[0032] As Figure 4 As shown, a fixing plug 26 is screwed inside the outer wall at the right end of the sampling pipe 25 to block the sampling port on the right side of the sampling pipe 25. Inside the guiding pipe 21, a fixing block 24 is provided. Inside the circular outer wall at the front end of the fixing block 24, a storage groove 23 is opened to store the oil entering from the liquid inlet 22. A fixing rod 28 is fixedly connected to the outer wall at the right end of the fixing block 24.

[0033] By screwing the fixing plug 26 into one end of the sampling pipe 25, one end of the sampling pipe 25 is sealed to prevent the oil from dripping and leaking when sampling is not required. Inside the guiding pipe 21, a fixing block 24 with a storage groove 23 is provided. When sampling is required, by rotating the fixing rod 28, the fixing block 24 is driven to rotate, aligning the storage groove 23 opened on the fixing block 24 with the liquid inlet 22, so that the oil can be introduced into the storage groove 23 through the liquid inlet 22. Then, by continuing to rotate the fixing block 24, the oil in the storage groove 23 can be guided into the sampling pipe 25 and discharged outwards.

[0034] As Figure 4As shown, a handle 29 is fixedly connected to the outer wall of the right end of the fixed rod 28 to drive the fixed block 24 to rotate under an external force. A sealing gasket 27 is fixedly connected to the circular outer wall of the fixed rod 28 near the left side to fill the gap between the fixed block 24 and the inner wall of the guide pipe 21. An installation plate 30 is arranged on the outer wall of the right end of the guide pipe 21. A fixing bolt 31 is arranged between the installation plate 30 and the guide pipe 21. A fixing hole that fits with the fixed rod 28 is opened inside the installation plate 30.

[0035] By grasping the handle 29, the fixed rod 28 can be driven to rotate. During the rotation process, through the sealing of the sealing gasket 27, when guiding the oil fluid, the situation of oil fluid leakage from the guide pipe 21 can be prevented. By unscrewing the fixing bolt 31, the installation plate 30 can be removed, and when there is no oil in the fuel tank 18, the fixed block 24 can be replaced and cleaned.

[0036] As Figure 1 shown, a one-way valve 3 is arranged between multiple pump bodies 6 and the pressure measuring hoses 16 to guide the flow direction of the oil fluid. A butterfly valve 4 is arranged on one side of each of the multiple pressure measuring hoses 16. One ends of the multiple pressure measuring hoses 16 are commonly connected to a filter 11. A cooler 9 is fixedly connected to the upper outer wall of the fuel tank 18. An oil discharge port b15 is arranged on the rear outer wall of the filter 11. A line pipe 8 is arranged between the upper outer wall of the cooler 9 and the motor 1.

[0037] When the hydraulic oil passes through the filter 11, impurities are removed, and it flows through the cooler 9 to reduce the temperature, ensuring that the hydraulic oil works within a suitable temperature range. The butterfly valve 4 allows the oil fluid flow to be adjusted as needed. The pressure measuring hose 16 monitors the system pressure, and the filtered oil fluid is transmitted to the actuator through the oil discharge port b15.

[0038] As Figure 1 shown, a connection port 5 is arranged on the upper outer wall of the fuel tank 18. A pressure gauge 20 is arranged on the upper outer wall of the connection port 5. An accumulator oil return hole 12 and an oil return port 14 are arranged on the upper outer wall of the fuel tank 18 near the rear side. A transmission wire pipe 10 is arranged on the rear outer wall of the motor 1 to transmit signals to the pump body 6. A cooling water inlet 7 and a cooling water outlet 19 are respectively arranged on the front outer wall of the cooler 9 near the upper and lower sides. Cleaning covers 17 are respectively arranged on the front outer wall of the fuel tank 18 near the left and right sides.

[0039] The motor 1 starts and sends a control signal to the pump body 6 through the conveying pipeline 10, while driving the pump body 6 to work. The pump body 6 sucks hydraulic oil from the fuel tank 18, pressurizes the oil through the one-way valve 3 and the pressure measuring hose 16 and transports it to the system. The pressure gauge 20 displays the system pressure at any time. The operator can adjust the working state of the system according to the real-time data to ensure safety and efficiency. The used hydraulic oil flows back to the fuel tank 18 through the oil return port 14 and the accumulator oil return hole 12 to form a closed-loop circulation, enhancing the energy utilization rate. By opening the cleaning cover 17, the inside of the fuel tank 18 can be cleaned.

[0040] The implementation principle of this embodiment is as follows: During hydraulic operations, the motor 1 starts, driving the pump body 6 to work. The pump body 6 sucks hydraulic oil from the fuel tank 18 and transports it to the hydraulic system through pressurization. At the same time, the pressure measuring hose 16 monitors the system pressure. According to the pressure feedback by the pressure measuring hose 16, the control system can adjust the operating state of the motor 1 in a timely manner, thereby improving the energy utilization efficiency. The oil discharge port a13 transports the pressurized hydraulic oil to the hydraulic actuator connected to the pump station to achieve effective energy transfer. The used hydraulic oil flows back to the fuel tank 18 through the oil return port 14 to realize the recycling of hydraulic oil. When it is necessary to sample and detect the oil, the oil inside the fuel tank 18 can be guided into the sampling tube 25 through the liquid inlet 22 opened on the guiding tube 21. Place the sampling tube 25 or the corresponding container at one end of the sampling tube 25 in advance. After receiving the sampled oil, subsequent analysis of the oil can be carried out.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
