Abstract
The utility model relates to a vertical type fire pump with pressure of a water outlet adjustable. The fire pump comprises a motor seat, a motor installed on the motor seat, a sleeve and a base seat, wherein the lower end of the sleeve is installed on the base seat, the motor seat is connected with the upper end of the base seat, and a water inlet and a water outlet are formed in the base seat. A pump shaft, impellers and guide vanes are arranged in the sleeve, wherein the upper end of the pump shaft extends into the motor seat and is connected with a motor shaft of the motor through a coupler, the lower end of the pump shaft is installed in the base seat, and the impellers and the guide vanes are sleeved on the pump shaft. The water outlet is provided with a pressure adjusting device, wherein the pressure adjusting device is fixed on the base seat through a bolt. According to the vertical type fire pump with the pressure of the water outlet adjustable, the pressure adjusting device is additionally arranged on the water outlet of an existing vertical type fire pump, and then the pressure adjusting device and vertical type fire pump are combined to form the novel vertical type fire pump with the pressure of the water outlet adjustable, the pressure of the water outlet can be set as required, and therefore an effect of constant pressure is achieved.
