Specifically, offering entrance and exit on the pump housing, the entrance is axially horizontally disposed, and the outlet is axial
It is vertically arranged.
Compared with prior art, beneficial effect is: self-sucking non-plugging dredge pump is set by the uniqueness of the pump housing, impeller channel
Meter, can the self suction clean water pump as be not necessarily to install bottom valve and water like that, and can suction contain bulky grain solid and long fine
Impurity liquid is tieed up, it is optimal to be widely portable to the chemical industry rings such as municipal drainage project, river embankment cultivation, light industry, papermaking, weaving
Transh pump；Compared to domestic similar product, the application have structure is simple, self-priming performance is good, pollution discharge capability is strong, it is energy-efficient,
The features such as easy maintenance.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model mortar pump.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of positional relationship is described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
As shown in Figure 1, a kind of self-sucking non-plugging dredge pump, specifically includes that the pump housing 6, impeller 9, pump shaft 13, bearing block 12 are logical
Later lid 8 is fixed on 6 side of the pump housing, and liquid storage chamber 61 and flow cavity 62 are divided into inside the pump housing 6, and liquid storage chamber 61 passes through
Circulation port and return port and flow cavity 62 are interconnected, and discharge connection 5 and 1 connection of entrance sleeve and flow cavity 62, pump shaft 13 pass through
It wears bearing block 12 to be connected to impeller 9 and the impeller 9 in flow cavity 62 is driven to rotate, bearing cap 15 is mounted on 12 outside of bearing block.
Above scheme, the entrance sleeve 1 are connected to the entrance of flow cavity 62, entrance sleeve 1 by import valve seat 3
It is equipped with import check valve 2 with 3 junction of import valve seat, discharge connection 5 is connected to flow cavity 62 by gas-liquid separation pipe 7.Flowing
62 upper and lower ends of chamber are bending, and the lower bending of flow cavity 62 presents lower bifurcation channel, and the setting of impeller 9 is curved under flow cavity 62
