Abstract
The utility model relates to a vertical sewage pump, wherein a motor is arranged on a bearing body through a connecting frame, a pump body which is fixedly arranged on a base and the bearing body are fixedly arranged, a pump shaft and an output shaft of the motor are fixedly connected by a coupling, an impeller fixing sleeve is arranged on the lower end of the pump shaft, a shaft sleeve is fixedly sleeved on the pump shaft closing to the impeller, a packing box is sleeved on the shaft sleeve in gaps, an outer edge is pressed between the pump body and the bearing body, a ring-shaped boss which is arranged on the inner wall of the packing box separates a cavity body between the inner wall of the packing box and the shaft sleeve into an upper cavity body and a lower cavity body, and a sealing part is arranged in the upper cavity body. The vertical sewage pump is characterized in that a water bearing which is sleeved on the shaft sleeve is added in the lower cavity body, wherein the water bearing comprises a bearing seat and a bearing, the bearing is sleeved in the bearing seat in interference, the bearing seat is fixedly connected with the packing box, and a bearing pressing cover is plugged on the bearing seat and the bottom end of the bearing. The vertical sewage pump reduces the swinging of the pump shaft through arranging the water bearing, enhances the stiffness of the pump shaft, and increases the stationarity of the pump when operating.
Description
Technical field
The utility model relates to a kind of vertical sewage pump, belongs to the pollution discharge pump technical field.
Background technique
Existing vertical sewage pump is that pump and motor adopt straight connection type, and motor is a motor special.What the vertical sewage pump of this structure adopted is motor special, therefore to the maintenance inconvenience of pump; So because be that straight connection type pump shaft cantilever is oversize, the vibration of axle is big, so pump is not steady when operation, also can influence the working life of sealing configuration.
Summary of the invention
The purpose of this utility model provide a kind of can overcome the vibration of above-mentioned defective, pump shaft little, operate steadily, the vertical sewage pump of sealing configuration long service life.Its technological scheme is:
Comprise motor, pump shaft, bearing support, link press span, axle sleeve, the pump housing, base, wherein motor is installed on the bearing support through link press span, be fixedly mounted on the pump housing and bearing support fixed installation on the base, pump shaft is fixedlyed connected through coupling with motor output shaft, impeller is fixedly set in the lower end of pump shaft, axle sleeve is fixedly set on the pump shaft near impeller, the stuffing box gap is sleeved on the axle sleeve, outward edge is fitted between the pump housing and the bearing support, annular boss on the stuffing box inwall is divided into upper cavity and lower chamber with the cavity between stuffing box inwall and the axle sleeve, wherein be provided with Sealing in the upper cavity, it is characterized in that: in lower chamber, set up the water middle (center) bearing that is sleeved on the axle sleeve, the water middle (center) bearing comprises bearing support and bearing, its middle (center) bearing interference is sleeved in the bearing support, bearing support is fixedlyed connected with stuffing box, and the bearing gland shutoff is in the bottom of bearing support and bearing.
Described vertical sewage pump, pump shaft adopts the step type rotating shaft.
The utility model compared with prior art, its advantage is:
1, owing to above impeller, set up the water middle (center) bearing, shortens the length of pump shaft between main bearing and the impeller, reduced the radially working load of main bearing, increased the strong point of pump shaft, strengthened the rigidity of pump shaft;
2, set up the water middle (center) bearing, reduced the swing of pump shaft, improved the transmission efficiency of pump shaft, the working life of the sealing configuration that extended power;
Stationarity when 3, significantly improving pump operation.
