Abstract
The invention relates to a pump body packing box of a coal cutter. The pump body packing box comprises a packing base connected to a pump shaft and packing and is characterized in that a packing ring is connected in the packing base, the end of the packing base is connected with a packing gland, an I-type ring groove is formed in the packing ring, and the packing is arranged between the packing ring and the packing gland. Compared with a traditional pump body packing box, the pump body packing box of the coal cutter has the advantages of being simple in structure, convenient to load and unload, good in working effect and small in size.
Description
Technical field:
The present invention relates to coal mining apparatus field, particularly the pump sealer of coal winning machine.
Background technique:
In coal mining equipment, water pump is requisite equipment, wherein between the pump shaft of High Rotation Speed and fixed pump body, need there is sealing configuration, this sealing mechanism is called Stuffing box, its effect is the leakage that reduces pressure press water in the time of draining, prevent that in water suction side air from entering in pump, and play that diversion is lubricated, the effect of cooling pump shaft.Traditional its shortcoming of stuffing box packing case is complex structure, handling inconvenience.
Summary of the invention:
The applicant, for the above-mentioned shortcoming of traditional pump housing stuffing box packing case, studies and improves, and a kind of pump housing Stuffing box of coal winning machine is provided, and it has simple in structure, feature easy to loading and unloading.
In order to address the above problem, the present invention adopts following scheme:
A kind of pump housing Stuffing box of coal winning machine, comprise the filler seat and the filler that are connected on pump shaft, it is characterized in that: bonding pad ring in described filler seat, the end bonding pad gland of filler seat, described packing ring has I shape annular groove, and described filler is placed between described packing ring and Gland.
Technique effect of the present invention is:
The present invention is simple in structure, more traditional pump housing Stuffing box, and it has easy to loading and unloading, good working effect, the advantage that volume is little.
Brief description of the drawings:
Fig. 1 sectional structure chart of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, the present invention includes the filler seat 2 and the filler 3 that are connected on pump shaft 1, it is characterized in that: the interior bonding pad ring 4 of described filler seat 2, the end bonding pad gland 5 of filler seat 2, described packing ring 4 has I shape annular groove 6, and described filler 3 is placed between described packing ring 4 and Gland 5.
Claims (1)
