Description

Technical Field

[0001] The invention belongs to the technical field of water pumps, and in particular relates to a fully adjustable submersible pump. Background Art

[0002] Submersible pumps are vane pumps. They have the characteristics of large flow and low head, and are suitable for low water level conditions. Therefore, they are often the preferred pump type for agricultural irrigation and drainage, urban water supply and drainage, and other projects. Therefore, a fully adjustable submersible pump is needed to solve the above problems. At present, submersible pump blades mainly use fixed blades and semi-adjustable blades, and there is no fully adjustable blade method, which limits the running performance of the pump. Summary of the invention

[0003] In view of the above problems existing in the prior art, the present invention provides a fully adjustable submersible pump.

[0004] The technical solution adopted by the present invention is as follows: a fully adjustable submersible pump, including a submersible motor, a main water pump, a main shaft, and also includes a blade adjustment mechanism, an oil chamber, a vane oil receiver and a vane control system. The blade adjustment mechanism is installed in the water pump hub body, including a relay, a vane pivot, and a vane mechanism. The relay is connected to the vane mechanism through the vane pivot, and the vane mechanism is connected to the water pump blades. The oil chamber is arranged between the submersible motor and the main water pump, and the main shaft passes through the oil chamber and is connected to the submersible motor. The main shaft is a hollow shaft. The vane oil receiver and the vane control system are installed on the main shaft located in the oil chamber and rotate synchronously with the main shaft. A radial hole is provided on the main shaft, and the oil pipe is connected to the vane oil receiver and the relay through the radial hole and the hollow main shaft.

[0005] Furthermore, it also includes a vane opening sensor, which is fixed on the main shaft and is used to detect the displacement of the vane pivot and convert it into a change in the angle of the water pump blade.

[0006] Furthermore, it also includes a ground-mounted external controller, which is connected to the rotor blade control system.

[0007] A fully adjustable submersible pump of the present invention can realize fully automatic adjustment of water pump blades, so that the water pump always operates in a high-efficiency zone, and widens the operating performance of the water pump; the vane oil receiver and the vane control system are installed on the main shaft located in the oil chamber, and rotate synchronously with the rotation of the main shaft, and it is in a relatively static state with the submersible motor and the rotating part of the main water pump at any time to avoid oil leakage; the blade angle is displayed by the vane opening sensor on the main shaft, and the vane control system is connected to a ground external controller, so that the water pump blade angle can be remotely controlled, remotely displayed and fully automatically adjusted.
