Problems solved by technology
[0003] At present, when the existing centrifugal water pump is actually used, the impeller idling often occurs when the actual pump body is not filled inside the pump body, the actual impeller is damaged greatly, and the overall durability is not good. In addition, the impeller of the existing centrifugal water pump lacks good When the actual impeller rotates and guides the flow, its water outlet efficiency is not high, and the overall practical application value is not high

Embodiment 2
[0027] The difference between this embodiment and Embodiment 1 is that the outer walls of the two side walls of the impeller 6 are ring-shaped and fixedly connected with a plurality of flow guide strips 7 at equal distances. By setting an annular flow guide mechanism on the impeller 6 of the centrifugal water pump, the actual impeller When carrying out rotation and diversion work, its water outlet efficiency is high, and the overall practical application value is high. There are installation holes 17 between the upper and lower side walls of the fixing seat 15 away from the installation base 1, which is beneficial to cooperate with bolts for overall installation work. The installation method The top wall of the flange 4 is located on the outside of the opening and is provided with an annular groove 18. The annular groove 18 is provided with a plurality of through holes at equal distances in a ring. The top wall of the mounting flange 4 is located on the inside of the opening and...

The invention provides a high-water-yield idling-resistant centrifugal water pump, and relates to the technical field of centrifugal water pumps. The high-water-yield idling-resistant centrifugal water pump comprises a mounting base, a mounting frame is fixedly connected to one side of the top wall of the mounting base, a pump body is fixedly mounted at the top of the mounting frame, a mounting flange is fixedly mounted at a water outlet in the upper portion of the pump body, a water level sensor is arranged on the upper portion of the pump body, an impeller is arranged in the pump body, a pump shaft is arranged in the middle of the impeller, and a plurality of flow guide strips are annularly and fixedly connected to the outer side walls of the two side walls of the impeller at equal intervals. According to the high-water-yield idling-resistant centrifugal water pump, a liquid level sensor and a friction transmission mechanism capable of being combined and separated are arranged, it can be guaranteed that when the interior of the pump body is not filled with the impeller, idling work of the impeller does not occur, actual damage to the impeller is small, and the overall durability is good; and in addition, an annular flow guide mechanism is arranged on the impeller of the centrifugal water pump, when the impeller rotates to guide flow actually, the water outlet efficiency is high, and the overall actual application value is high.
Description
technical field [0001] The invention relates to the technical field of centrifugal water pumps, in particular to an idling-resistant centrifugal water pump with high water output rate. Background technique [0002] Centrifugal pump (foreign name: Centrifugal pump) refers to a pump that transports liquid by the centrifugal force generated when the impeller rotates. It is mainly composed of impeller, pump body, pump shaft, bearing, sealing ring and stuffing box. Its main features include: compact structure, wide range of flow head, uniform flow, stable operation, small vibration, low maintenance and repair costs, etc. [0003] At present, when the existing centrifugal water pump is actually used, the impeller idling often occurs when the actual pump body is not filled inside the pump body, the actual impeller damage is relatively large, and the overall durability is not good. In addition, the impeller of the existing centrifugal water pump lacks good When the actual impeller...
