Description
Technical field
The utility model belongs to equipment for liquid transportation technical field, relates to a kind of pipeline mounted pump, is specifically related to a kind of riser pump housing.
Background technique
Pump is conveying liquid or the machinery making fluid pressurization, is mainly used to the liquid such as conveying water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal, also can carries gas, liquid mixture and the liquid containing suspended solids.The medium that traditional suction pump is pumped is only limited to pure liquid, when containing corrosive chemical components in liquid, suction pump rotatingshaft can be caused to corrode makes the pump housing impaired, need to split the whole pump housing when changing Sealing, not only increase maintenance cost, its performance cannot be recovered after blade wear, reduce the working life of bearing of knowing clearly simultaneously.
Vertical pipeline mounted pump is the pump-type comparatively commonly used, it is large-scale tall buildings water system capital equipment, have that lift is high, pressure is large, load is little, the life-span is long, it is little to take up room, efficiency is high and the feature such as environmental protection, be widely used in family expenses high residential building, heavy construction, (commercial complex of hotel), railway station, airport contour level building.Impeller due to vertical pipeline mounted pump is installed on impeller shaft, impeller shaft is in transmission connection by the output shaft of coupling and motor, there is the problems such as assembling is loaded down with trivial details, assembly precision is poor and axial dimension is longer, in addition, also there is poor sealing performance in existing vertical pipeline mounted pump, flimsy problem.
Model utility content
The utility model provides a kind of riser pump housing, to improve the sealing of the pump housing, sealing and working life, improves the usability of vertical pipeline mounted pump.
The technical solution of the utility model is: the riser pump housing, comprises into water cavity, hydraulic pressure cavity, impeller cavity and water outlet cavity.Be provided with water intake and water inlet flow channel in water inlet cavity, water outlet cavity is provided with outlet passage, and the inside of hydraulic pressure cavity is water inlet and outlet working room, and the inside of impeller cavity is impeller working room.Water intake is communicated with water inlet and outlet working room by water inlet flow channel, and water inlet and outlet working room is communicated with impeller working room, and impeller working room is communicated with outlet passage.Water inlet cavity is provided with water-in flange, and water outlet cavity is provided with water-output flange.The outside of impeller cavity is provided with motor adpting flange, is connected with power motor by motor adpting flange.
The pump housing is provided with into water stiffening rib, water outlet stiffening rib and middle reinforced rib.Water inlet stiffening rib is between water inlet cavity and impeller cavity, and water outlet stiffening rib is between water outlet cavity and impeller cavity, and middle reinforced rib is positioned at the outside of hydraulic pressure cavity.The pump housing is iron casting.Water-inlet cavity inner flow passage and water-inlet cavity runner is provided with in the pump housing.
The utility model riser pump housing has the advantage of strong, the wear-resisting and long service life of rigidity, is easy to highi degree of accuracy processing, combines closely, fixation, does not loosen and is out of shape, the sealing of the pump housing and safety in utilization good, improve the usability of vertical pipeline mounted pump.
