Abstract
The utility model relates to a packing seal box for a water pump. The packing seal box comprises a packing box body (4) arranged between a pump body (5) and a bearing pedestal (1). A packing chamber (4a) filled with packing is arranged inside the box body (4). A gland (3) is arranged at the front end of the box body, an installation hole (4b) communicated with the packing chamber is formed in the rear end of the box body, the installation hole and a pump shaft (2) are coaxially connected in a matched mode, and the pump shaft penetrates through the gland through the installation hole. The packing seal box for the water pump is characterized in that a replacing ring (6) in excessive fit connection with the installation hole is arranged in the installation hole. The packing seal box for the water pump has the advantages of being simple in structure, good in sealing effect and high in reliability, reducing the water pump maintenance cost, and prolonging the service life of the whole water pump.
Description
Technical field
The utility model relates to water pump field, particularly relates to a kind of filling sealing tank for water pump.
Background technique
Current existing water pump adopts gland sealed method to seal the space between pump case and pump shaft more, with prevent current in pump overflow with pump outside the entering of gas.In the time that the running of water pump long-play or pump shaft has unbalanced situation to occur, between Stuffing box and pump shaft, easily produce wearing and tearing, in the time that wear extent increases to a certain degree, filler in Stuffing box can leak from the fray between Stuffing box and pump shaft, water pump cannot be run well, shorten the working life of water pump complete machine, there is higher maintenance rate and the cost of overhaul.
Summary of the invention
The purpose of this utility model is to solve existing employing gland sealed water pump Stuffing box easily and pump shaft produces the problem of wearing and tearing, and a kind of filling sealing tank for water pump is provided.
The purpose of this utility model is achieved by the following technical programs:
A kind of filling sealing tank for water pump, comprise the Stuffing box casing of being located between the pump housing and bearing support thereof, in casing, be provided with and fill Packed filler chamber, casing front end is provided with gland, rear end is provided with the mounting hole being communicated with filler chamber, mounting hole is connected with pump shaft coaxial cooperation, pump shaft through gland, is characterized in that being provided with in mounting hole the more ring change being excessively connected with it through mounting hole.
The described pump shaft through Stuffing box casing is provided with packing cover, packing cover along pump shaft through ring change more through gland, to prevent the wearing and tearing to pump shaft of more ring change in Stuffing box casing mounting hole.
The circumference of described more ring change is provided with annular boss, and annular boss is placed in filler chamber.
The beneficial effects of the utility model are simple in structure, good sealing effect, and reliability is high, in having reduced device maintenance cost, has extended the working life of complete machine.
Just accompanying drawings and embodiment further illustrate the utility model below.
