Description

Technical Field

[0001] This utility model relates to the field of impeller flow channel self-adjusting gradual flow direction centrifugal pump technology, and more specifically to an impeller flow channel self-adjusting gradual flow direction centrifugal pump body. Background Technology

[0002] The main function of a self-adjusting, gradually changing flow direction centrifugal pump body is to achieve efficient and stable liquid transportation, and it is suitable for application scenarios with high requirements for efficiency and operational stability.

[0003] Existing centrifugal pumps are difficult to dynamically adjust the output speed of the drive motor according to the actual flow rate and operating conditions of the water. This means that the pump may not always operate in the high-efficiency zone, resulting in increased energy consumption and reduced operating efficiency. When the device is in a low liquid level, high head or medium with high viscosity, the pump's self-priming ability and suction efficiency will decrease significantly. It has poor adaptability when facing different media, flow rates or head requirements.

One end of the first fixing rod 305 is distributed in a ring and fixedly installed on the rear wall of the internal hollow disk 306, and the other end of the first fixing rod 305 is fixedly installed on the outer wall of the protective shell 301.

[0026] The working principle of this utility model:

[0027] Place the device horizontally above the ground. Connect the inlet 202 to the pumping pipe and the outlet 203 to the drain pipe. The device will then begin operation. The output of the drive motor 401 will rotate the turntable 502. This rotation will cause the impeller 504, which is fixedly mounted above, to rotate. The impeller 504 generates suction, drawing water through the inlet 202 into the device. As the water enters, its flow will cause the speed measuring impeller 304 to rotate. The speed measuring motor 302 will record the speed in real time. The rotational speed of the speed-measuring blade 304 is sent to the fixed speed signal controller 303. After receiving the speed information, the speed signal controller 303 analyzes it. If the speed value is lower than the standard speed value, it defines this signal as a low speed signal and sends it to the signal receiving controller 402. After receiving the low speed signal, the signal receiving controller 402 controls the drive motor 401 to increase its power, thereby realizing the self-adjustment of the device. The water inside the device enters the rear of the turntable 502 through the water flow channel 503 and is discharged to the designated position after passing through the drain outlet 203.
