Abstract
A self priming mud pump pertains to the pump field, comprising a transmission shaft. The pump is characterized in that: a sealing loop is arranged on the transmission shaft and fixedly connected with the transmission shaft; a sealing ring is positioned on the transmission shaft at one side of the sealing loop; the sealing loop is connected with the sealing ring. The sealing loop of the utility model is contacted with the sealing ring; during the period of rotation of the transmission shaft, the sealing loop rotates around the transmission shaft, while the sealing ring does not rotate; the seal of the transmission shaft is realized by the friction combination between the seal ring and the seal loop; since the friction between the seal loop and seal ring is small, the utility model has no air and liquid leakage when in use and has long service life and good sealing effect.
Description
Technical field
The utility model belongs to the pump field, relates generally to a kind of shaft seal that has seal ring.
Background technique
Present known self-priming slurry pump, the sealing means of its transmission shaft generally adopts packing seal.In this kind sealing configuration,, cause therefrom the space occurring between transmission shaft and the filler, so sealing effect is bad, has influenced the workmanship of pump owing to filler and transmission shaft friction cause the wearing and tearing gradually of filler.
The model utility content
The purpose of this utility model provides a kind of self-priming slurry pump of good sealing effect, its technological scheme that adopts is: design a kind of self-priming slurry pump, comprise transmission shaft, it is characterized in that being provided with and its seal ring that connects firmly mutually on the transmission shaft, on the one side transmission shaft of seal ring seal ring is set, seal ring and seal ring link.
The utility model is at the arranged outside setting sleeve of seal ring.
The utility model to two setting sleeves are set, is provided with spring on the periphery of setting sleeve small end along transmission shafts.
Be in contact with one another between seal ring of the present utility model and the seal ring, in the transmission shaft rotation process, seal ring rotates with axle and seal ring does not change, and realizes sealing to transmission shaft by the frictional engagement between seal ring and the seal ring; Because the friction factor between seal ring and the seal ring is little, thereby in the using process of slurry pump, does not have and reveal, do not have gas leakage, water leakage phenomenon, long service life, good sealing effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further elaborated.
Accompanying drawing 1 is the utility model embodiment's a structural representation;
Accompanying drawing 2 is A-A structural representations of Fig. 1.
Embodiment
As shown in the figure: be provided with and its seal ring that connects firmly mutually 2 on the transmission shaft 5, on the side transmission shaft of seal ring 2 seal ring 1 be set, seal ring 1 contacts with seal ring 2.For seal ring is located, at the arranged outside setting sleeve 3 of seal ring; For making seal ring and transmission shaft closely linked, make seal ring rotate synchronously with transmission shaft, spring 4 is set on the periphery of setting sleeve small end, lean on the elastic force of spring that seal ring tightly is enclosed within on the transmission shaft.
The utility model along transmission shafts to two setting sleeves and seal ring and seal ring are set.In the transmission shaft rotation process, seal ring 2 rotates with axle and seal ring 1 does not change, and realizes sealing to transmission shaft by the frictional engagement between seal ring and the seal ring; Because the friction factor between seal ring and the seal ring is little, thereby realized the sealing of transmission shaft effectively.
