Problems solved by technology

However, since the suction device and the centrifugal pump of the two self-priming pumps are all driven by the same shaft located on the side of the motor, the overall structure is relatively complicated, the processing and manufacturing are difficult, and the amount of maintenance and disassembly is large. It cannot be matched with the existing centrifugal pump and converted into a self-priming pump, which is also not conducive to serialization

Embodiment Construction

[0040] As shown in Figure 2, the strong self-priming pump that I have designed according to the above technical scheme consists of a suction device, a clutch device, a motor and a centrifugal pump that are easy to load and unload.

[0041] The structure of the suction device is the same as the suction device in ZL92209212.5. It includes: a pressure chamber body 11 provided with a one-way suction port 111, a pressure chamber body cover 12 provided with a one-way exhaust port, and A suction mechanism composed of an air hole 132 and an actuating body 13 of a membrane valve 131; a suction mechanism composed of a connecting rod 141, a shaft pin 142, a crank 143, a bearing 144 and an eccentric friction clutch sleeve 145 sleeved with the vertical upward shaft of the motor The transmission mechanism of the air mechanism.

[0042] The clutch device is composed of a clutch friction part and a clutch pressure part; the clutch friction part is composed of an eccentric friction clutch sleeve 1...

Abstract

It is a kind of strong self-priming pump made up of the electric engine, the centrifugal pump, the getter device, the air intake duct and the suction duct. It has the characteristics that the electric motor is bilateral. And one side is the normal length and the other is lengthening. There is a clutch that is connected with the normal length axle. The decentral confriction on-off cover in the air intake duct was jointed with the lengthening axle. The composition is very simple which is easily produced, loaded and unloaded and repaired.

Description

Technical field [0001] The invention relates to a centrifugal pump, in particular to a self-priming pump composed of a centrifugal pump and a vibrating membrane suction device. Background technique [0002] In view of the shortcomings of general centrifugal pumps that the pump cavity must be filled with water in advance when starting, I applied for ZL92209212.5 "strong self-priming sewage pump" in 1992 after referring to the structure of foreign self-priming pumps, which described the vibrating membrane in detail. The structure of the suction device and its working principle, and the connection relationship between it and the centrifugal pump are described, which will not be repeated in this article. [0003] Due to market demand, on the basis of the success of the above-mentioned patented technical solution, I designed a "vertical strong self-priming drainage pump" which is a combination of a long-axis centrifugal pump and a vibrating membrane suction device as shown in Figure 1...
