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 film suction device. Background technique

[0002] Aiming at the shortcomings of general centrifugal pumps that must fill the pump cavity with water in advance, after referring to the structure of self-priming pumps abroad, I applied for ZL92209212.5 "Strong Self-priming Sewage Pump" in 1992, and described the vibrating membrane in detail. The structure and working principle of the suction device, and its connection with 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 solutions, I have designed such figure 1 The "vertical strong self-priming drainage pump" composed of a long-axis centrifugal pump and a vibrating membrane suction device has obtained the ZL99244983.9 patent.
