Description
Technical field
The utility model relates to a kind of portable fire pump.
Background technique
The portable fire pump of Shi Yonging mostly is vane wheel type centrifugal pump greatly in the market, during use, need earlier will the pump housing and with aqueduct that the water source is connected in fill diversion, use cumbersomely, and the portable fire pump lift of this structure is also shorter.Above shortcoming is fatal for fire-fighting operation, and therefore developing a kind of portable fire pump easy to use, that lift is big has just become the task of top priority.
Summary of the invention
Technical problem to be solved in the utility model is at above deficiency, provide a kind of easy to use, do not need water, the portable fire pump that lift is big.
The technological scheme that its technical problem that solves the utility model adopts is: portable fire pump, comprise the pump housing, be provided with rotating shaft in the pump housing, rotating shaft is provided with impeller, have the water inlet on the impeller, have water intake and water outlet on the pump housing, water intake is connected with the water source by aqueduct, also is provided with the structure of bleeding between described water intake and aqueduct.
The above-mentioned structure of bleeding comprises columniform housing, housing sealed at both ends has inlet hole and air outlet hole on the barrel of cylindrical housings, be provided with eccentric wheel in columniform housing, have axial groove on the eccentric wheel surface, be provided with the centrifugal film that can radially move in the groove.
The length sum of above-mentioned eccentric radius and centrifugal film is greater than the radius of cylindrical housings.
Have four grooves on the above-mentioned eccentric wheel.
Above-mentioned eccentric wheel shaft extends to outside and is furnished with the power input device.
The place, water inlet of above-mentioned impeller is provided with the worm propeller coaxial with impeller shaft.
The beneficial effects of the utility model are: owing to be provided with the structure of bleeding between the pump housing and aqueduct, therefore in use, do not need water, the structure of bleeding can pump the gas in the aqueduct, water is full of aqueduct under the pressure of atmosphere, use easily, and place, the impeller water inlet in the pump housing has increased by a worm propeller simultaneously, improve the speed that current enter impeller, made the lift of portable fire pump become big.
