Abstract

The invention provides an automatic packing adjusting and sealing structure for a water pump unit, which can automatically adjust the compaction degree of a packing in the working process of the water pump unit, and has high adjusting accuracy. The structure comprises a packing seat and the packing, wherein the packing seat is arranged outside a shaft sleeve of a pump shaft; the packing is packed in a packing cavity of the packing seat and is compacted by a packing gland; and the packing gland is connected with the packing seat through an adjusting bolt. The structure is characterized in that: a spring is sleeved outside the adjusting bolt and is pressed in a spring seat through a nut.

Description

The automatic adjusting packing seal structure that is used for water pump assembly
Technical field
The present invention relates to the technical field of sealing technology of water pump assembly, be specially the automatic adjusting packing seal structure that is used for water pump assembly.
Background technique
Generally be used for water pump assembly packing seal structure it comprise the filler seat, the filler seat is installed on the axle sleeve outside of pump shaft, filler is loaded in packing cavity by the Gland sealing, Gland is connected and fixed by bolt and filler seat, in use in order to guarantee that gland sealed reliably need regulate the degree that compresses of filler, particularly when appearring in filler, wearing and tearing need guarantee reliably compressing of filler by regulating Gland, its shortcoming is: its Gland is directly fixed on the filler seat by regulating bolt, need manually rotation to regulate bolt during adjusting and regulate, its degree of regulation is poor, regulate difficulty.
Summary of the invention
At the problems referred to above, the invention provides the automatic adjusting packing seal structure that is used for water pump assembly, it can compress degree to filler and automatically adjust in the water pump assembly working procedure, the degree of regulation height.
Its technological scheme is such, it comprises filler seat and filler, described filler seat is installed on outside the axle sleeve of pump shaft, described filler is loaded in the packing cavity of described filler seat and by Gland and is compressed, be connected by regulating bolt between described Gland and the filler seat, it is characterized in that: described adjusting bolt outer cover is equipped with spring, described spring by nut press mounting in spring seat.
It is further characterized in that: the axle sleeve outside of described pump shaft also is set with air shroud, described air shroud is installed in the installation annular groove of described filler seat, described filler seat has compressed air line, described compressed air line and described air shroud pipeline connection.
Compare with the existing packing seal structure that is used for water pump assembly, beneficial effect of the present invention is: it is equipped with spring in adjusting bolt outer cover, spring is pressed in the spring seat by nut, after the wearing and tearing of the filler in the filler seat, the effect promotion Gland that the adjusting bolt is subjected to the external springs pretightening force compresses filler, thereby realize self-regulating effect, guarantee that sealing is reliable; The setting of air shroud; in case the needs of water pump assembly packing seal total failure in running occurring shuts down under the situation of sealing; thereby make the air shroud banding axle sleeve that expands rapidly by in air shroud, feeding pressurized air; play seal action effectively; avoid the pump shaft rear end equipment to be subjected to water impact to cause damage, further guaranteed reliable sealing.
Description of drawings
Fig. 1 is an automatic adjusting packing seal structure schematic representation of the present invention.
Embodiment
See Fig. 1, structure of the present invention comprises filler seat 9 and filler 1, filler seat 9 is installed on outside the axle sleeve 7 of pump shaft 11, filler 1 is loaded in the packing cavity of filler seat 9 and by Gland 10 and is compressed, be connected by regulating bolt 3 between Gland 10 and the filler seat 9, regulate bolt 3 outer cover spring 4 is housed, spring 4 press-fits in spring seat 5 by nut 6.Axle sleeve 7 outsides of pump shaft 11 also are set with air shroud 8, and air shroud 8 is installed in the installation annular groove 13 of filler seat 9, and filler seat 9 has compressed air line 14, compressed air line 14 and air shroud pipeline connection.Among Fig. 1,2 is packing ring, and 12 is slinger ring.
