Problems solved by technology

Since this type of centrifugal water pump does not have the self-priming function, the suction pipe and the pump body must be filled with water before starting each time to prepare for starting, which is time-consuming and laborious, and a large amount of water needs to be prepared. In addition, there are Defects of slow start, low suction and lift
The pipeline pump has no self-priming function. Once the water level in the pipeline is low, the water seal will be easily damaged and cause the pipeline to be paralyzed. In deep wells; for another commonly used pump - self-priming pump, it is also composed of pump body, impeller and pump shaft. There is a water injection pipe on the top to inject water into the pump body before starting the machine. Its disadvantages are: small flow rate and low suction ( less than 9 meters), low efficiency

Embodiment Construction

[0032] Such as Figure 1-4 As shown, the present invention provides a centrifugal pump, which is composed of a pump body 1, an impeller 2 and a pump shaft 3, and implemented in cooperation with a motor 4. The pump body 1 is provided with two impeller chambers, a self-priming impeller chamber 11 and a centrifugal impeller chamber 12, The self-priming impeller cavity 11 is located below the centrifugal impeller cavity 12, and its self-priming impeller cavity 11 is smaller than the centrifugal impeller cavity 12, and the two are separated by a pump cover 13, and the center of the pump cover 13 has a through hole through which the pump shaft 3 can pass. 131, and sealed by a water seal (not seen in the figure). A self-priming impeller 21 and a centrifugal impeller 22 are arranged in the two cavities respectively, and the self-priming impeller 21 and the centrifugal impeller 22 are installed on the same pump shaft 3; the pump body 1 is also provided with a discharge cavity 14 below,...

Abstract

An energy-saving efficient multi-purpose water pump is composed of pump body, centrifugal blade wheel, self-priming blade wheel, and pump shaft common to said both blade wheels. Said two blade wheels are respectively arranged the centrifugal cavity and self-priming cavity of pump body, which are isolated by pump cover. Its advantages are dual functions (centrifugal pump and self-priming pump), high delivery lift efficiency and flow, low energy consumption, and small size.

Description

technical field [0001] The invention relates to a water pump, in particular to a centrifugal water pump with self-priming function. Background technique [0002] The water pump currently used is composed of a pump body, an impeller, and a pump shaft, and is used in conjunction with a motor. The pump body is provided with a water inlet and a water outlet. The impeller is set in the impeller chamber of the pump body, and the outlet is connected to the side of the impeller chamber. , the direction of the outlet is consistent with the tangential direction of the impeller rotation. Its working principle is to use the high-speed rotating impeller to form a strong negative pressure at its center to divert the water from the low place to the high place for use. Since this type of centrifugal water pump does not have the self-priming function, the suction pipe and the pump body must be filled with water before starting each time to prepare for starting, which is time-consuming and l...
