[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1 As shown, a gas station pipeline that reduces the number of startups of the circulation pump 11 and reduces energy consumption includes a power oil tank 1. The power oil tank 1 provides the power oil storage required by the hydraulic system, reduces the fluctuation of the working pressure of the oil pump, and improves the overall stability. The power oil tank 1 is connected to the oil-using equipment 6 through the oil pipeline 2. The oil pipeline 2 outputs the power oil from the power oil pump 4 to each oil-using equipment 6. Through a reasonable pipeline layout, the flow resistance of the hydraulic oil is reduced and the delivery efficiency is improved. The oil-using equipment 6 is a mechanical equipment, mechanical tool, etc. that requires hydraulic support and can realize various mechanical actions. The use of power oil improves the efficiency of equipment use.

[0023] A power oil pump 4 is installed on the oil pipeline 2. This pump delivers the power oil by boosting the pressure, ensuring that the oil pressure meets the operating requirements. This effectively controls the oil pressure and maintains stable operation. The oil-consuming equipment 6 is connected back to the power oil tank 1. The oil used by the oil-consuming equipment 6 is then returned to the power oil tank 1 for circulation.

[0024] A circulation pipe 9 is led out from the power oil tank 1 and connected to the oil cooler 13. The oil cooler 13 can reduce the temperature of the hydraulic oil, ensure that the oil runs within the appropriate temperature range, increase the service life of the oil, and improve the working efficiency of the mechanical equipment. The circulation pipe 9 provides an effective oil circulation channel, and the temperature control capability is achieved through the oil cooler 13. A circulation pump 11 is set on the circulation pipe 9. The circulation pump 11 provides pumping power to provide circulating oil flow for the oil cooler 13 to ensure the temperature control requirements of the oil. The oil cooler 13 is connected to the power oil tank 1 and returns the cooled power oil to the power oil tank 1 for use. A connecting pipe 14 is led out from the oil pipeline 2 and connected to the oil cooler 13. The connecting pipe 14 is used to directly connect the oil pipeline 2 and the oil cooler 13. It relies on its own pressure to enter the oil cooler 13 for cooling. The return oil temperature is effectively controlled, which helps to quickly cool down and improve the heat dissipation capacity of the entire oil circuit.

[0025] The following is a detailed description of the design of the above key components:

[0026] The oil pipeline 2 is configured with two paths, each connected to an oil-consuming device 6. Two power oil pumps 4 are provided for each oil pipeline 2. The oil pipeline 2 utilizes a dual-path design, with two independent paths connected to different oil-consuming devices 6. A power oil pump 4 is provided on each oil pipeline 2 to pump oil.

[0027] The circulation pipe 9 is provided with a circulation valve 10. The circulation valve 10 controls the flow direction and flow rate of the oil and can be adjusted automatically or manually to adapt to the oil temperature requirements under different working conditions and improve the temperature control efficiency.

[0028] The circulation pump 11 is electrically connected to a circulation motor 12 , and the circulation motor 12 is used to drive the circulation pump 11 .

[0029] The power oil pump 4 is connected to the power oil tank 1 through a return pipe 7, and a return valve 8 is provided on the return pipe 7. The return pipe 7 guides excess oil back to the power oil tank 1, and the return valve 8 can control the opening and closing of the return pipe 7.

[0030] The connection position of the connecting pipe 14 on the oil pipeline 2 is located in front of the power oil pump 4, so as to form an effective oil circulation channel between the oil pipeline 2 and the oil cooler 13. Both oil pipelines 2 are connected to the oil cooler 13 through the connecting pipe 14.

[0031] The connecting pipe 14 is provided with a connecting valve 15. The connecting valve 15 is used to control the on / off state of the connecting pipe 14, and can be flexibly switched on and off when needed, such as when cooling the oil product to ensure that the oil flows smoothly to the oil cooler 13.

[0032] The oil pipelines 2 are provided with oil valves 3, and the number of the oil valves 3 corresponds to the number of the oil pipelines 2. An independent oil valve 3 is provided on each oil pipeline 2, so that the oil pipelines 2 in each flow direction can be controlled separately.

[0033] The power oil pump 4 is electrically connected to an oil pump motor 5 , which is used to drive the power oil pump 4 . The number of oil pump motors 5 corresponds to the number of power oil pumps 4 .
