It transmits the mechanical energy of a prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid-base solutions, emulsions, suspensions, and liquid metals, and can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps can generally be classified into three categories according to the working principle: positive displacement pumps, dynamic pumps, and other types of pumps. In addition to classification according to the working principle, they can also be classified and named by other methods.

The lubricating oil filter 14 is connected to the regulating valve seat 12 through the pumping pipe 13. Through the regulating valve seat 12 and the docking and connecting seat 11, the lubrication treatment work can be carried out. When the first gear disk 10 rotates, it can drive the engaged driven control mechanism 16 to rotate. At the same time, the second working oil cooler 21, the docking guide pipe 20, and the first working oil cooler 19 are connected, and the scoop tube controller 17 can be supplied with oil through the connecting branch pipe 18. The scoop tube controller 17 conducts regulation, and then injects working oil into the driven control mechanism 16, so as to control the oil content in the driven control mechanism 16 and control the transmission work of power to achieve the purpose of power transmission.

At the same time, the different oil filling amounts in the coupler part 24 can directly affect the control of the transmission speed to complete the work.
[0049] Embodiment 2
[0050] Based on Embodiment 1, as Figure 9-10 shown, the coupler part 24 includes a pump impeller 26, a first sealing seat 27 and a hydraulic control unit 31. The center of the pump impeller 26 is rotationally connected to the first sealing seat 27, and the side end of the pump impeller 26 is fixedly connected to the hydraulic control unit 31 in a sealed manner. The setting of the hydraulic control unit 31 facilitates the active control work, so that the push ring 33 moves in the turbine connecting rod 34, changing the distance between the turbine 32 and the first sealing seat 27, and better carrying out the speed regulation work. The pressure regulating pump 38 is connected to the hydraulic control seat 36 through the connecting branch pipe 37, so as to act on the push ring 33, making the push ring 33 move in the third sealing seat 35, and the driven can change the gap to achieve the purpose of speed regulation and ensure higher-speed operation.

The side end of the third seal seat 35 is also communicated with the hydraulic regulation seat 36, and the rear end of the hydraulic regulation seat 36 is communicated with the pressure regulating pump 38 through the communicating branch pipe 37. The hydraulic control unit 31 can perform automated guiding control work. The pressure regulating pump 38 is communicated with the hydraulic regulation seat 36 through the pressure regulating pump 38 and can conduct working oil between the pump impeller 26 and the pumping output rod 25. Moreover, the shifting ring 33 divides the third seal seat 35. The working oil conducted through the pressure regulating pump 38 on the right side can push the shifting ring 33 to move through the turbine connecting rod 34, changing the gap between the turbine 32 and the first seal seat 27, so as to better control the speed regulation. When the working oil remains unchanged, the closer the distance, the higher the transmission ratio. Thus, the docking turbine rod 30 is driven to move through the turbine connecting rod 34, and the docking turbine rod 30 drives the pumping output rod 25 to rotate to perform power transmission work. The turbine 32 and the shifting ring 33 can be telescopic through the turbine connecting rod 34, and a docking turbine rod 30 is fixedly connected to the side end of the turbine connecting rod 34. A groove structure for the movement of the shifting ring 33 is provided in the third seal seat 35, and at the same time, the left and right sides of the shifting ring 33 can be separated, so as to achieve efficient transmission while ensuring the stable performance of the shifting ring 33. The shifting ring 33 can perform transmission movement under balanced conditions. It can perform secondary regulation work under the control of the scoop tube controller 17, better assisting the power regulation work to achieve a more refined regulation purpose and improve the drive transmission ratio.
[0052] The pressure regulating pump 38 controls the oil on the right side of the shifting ring 33 through the communicating branch pipe 37 and the hydraulic regulation seat 36, controls the movement of the turbine 32 and the shifting ring 33 through the turbine connecting rod 34, and a groove for the movement of the turbine 32 and the shifting ring 33 is provided in the third seal seat 35 to change the distance between the turbine 32, the shifting ring 33 and the first seal seat 27.
[0053] The pump impeller 26 is hermetically fixed to the third seal seat 35. The guiding control pipe 29 on the third seal seat 35 is directly communicated with the left side of the turbine 32 and the shifting ring 33 to control the amount of oil between the turbine 32, the shifting ring 33 and the first seal seat 27.
[0054] In use, the hydraulic control unit 31 can perform automated guiding control work. The pressure regulating pump 38 is connected to the hydraulic regulation seat 36 through the pressure regulating pump 38, and can conduct working oil between the pump impeller 26 and the pumping output rod 25. Moreover, the pushing ring 33 separates the third sealing seat 35. The working oil conducted through the pressure regulating pump 38 on the right side can push the pushing ring 33 to move through the turbine connecting rod 34, changing the gap between the turbine 32 and the first sealing seat 27, so as to better control the speed regulation. When the working oil remains unchanged, the closer the distance, the higher the transmission ratio. Thus, the docking turbine rod 30 is driven to move through the turbine connecting rod 34, so that the docking turbine rod 30 drives the pumping output rod 25 to rotate for power transmission work. A groove structure for the movement of the pushing ring 33 is provided in the third sealing seat 35, and at the same time, the left and right sides of the pushing ring 33 can be separated. Thus, while achieving efficient transmission, the stable performance of the position where the pushing ring 33 is located can be ensured, enabling the pushing ring 33 to perform transmission movement under balanced conditions. It can perform secondary regulation work under the control of the scoop tube controller 17 for transmission, better assisting the power regulation work to achieve a more refined regulation purpose and improve the drive transmission ratio.
