Abstract
The utility model discloses a vertical single-stage fire pump which comprises a pump body (17). The vertical single-stage fire pump is characterized in that the pump body is provided with a medium flowing cavity formed by limiting of a shell, a pump cover (8) mounted on the upper portion of an impeller mounting cavity of the shell, an impeller (14) mounted in the impeller mounting cavity and a motor (1) vertically mounted on the pump body, the medium flowing cavity is provided with a medium inflowing passage (M), the impeller mounting cavity (N) and a medium outflowing passage (O), a paper pad (13) is mounted on a contact face of the pump cover and the shell, a power output end of the motor is connected with the impeller through a coupler (2), and a mechanical seal (7) is mounted between the coupler and the pump cover. The vertical single-stage fire pump has the advantages that the pump is compact in structure, small in size and attractive in appearance, and the vertical structure enables occupied area for mounting of the whole pump to be small; a suction inlet and a discharging opening of the pump are both in the horizontal direction, so that pipeline connection is simplified; and a rotor of the pump has low windability, so that the pump is stable in operation, small in vibration, low in noise and long in service life.
Description
Technical field
The utility model relates to a kind of vertical single stage fire water pump.
Background technique
At present, the vertical single stage fire water pump in use exists following drawback: a, pump structure complexity and volume bigger; The operation stability of b, pump is poor, working life is shorter.
The model utility content
At above shortcomings in the prior art, the utility model provides a kind of vertical single stage fire water pump.
To achieve these goals, the utility model adopts following technological scheme:
A kind of vertical single stage fire water pump, it comprises the pump housing (17), it is characterized in that, this pump housing has:
Limit the media flow cavity that forms by housing, it has medium flow channel (M), impeller installation cavity (N) and medium flow pass (O);
Be installed on the pump cover (8) on casing vane installation cavity top, itself and housing surface of contact are equipped with paper washer (13);
Be installed on the impeller (14) of impeller installation cavity;
Vertically be installed on the motor (1) of the pump housing, its clutch end connects impeller by conjuncted axle (2), between described conjuncted axle and the pump cover mechanical seal (7) is installed.
Described medium flow channel and medium flow pass coaxial arrangement.
Described medium flow channel is S-shaped.
Described conjuncted axle is equipped with water retaining ring (3).
Described conjuncted axle is connected with the impeller bonding.
Described pump cover and housing are installed by bolt (10) attaching nut (11).
Compared to existing technology, the utlity model has following advantage:
(1) pump structure compactness, little, the beautiful shape of volume, vertical structure make that whole pump housing installation floor space is little.
(2) Pump Suction Nozzle and discharge opening are simplified the connection of pipeline all in the horizontal direction.
(3) pump rotor has less winding degree, operates steadily, and vibrates for a short time, and noise is low, long service life.
