Abstract
The utility model relates to the technical field of slurry pump filler sealing, and particularly relates to a slurry pump filler sealing device. The filler sealing device comprises a pump body, a pump shaft inserted in the pump body, a filler box sleeved and connected with the pump shaft, a sealing element arranged in the filler box and a gland connected with the filler box via a bolt, wherein the sealing element is a rubber sealing gasket; and the rubber sealing gasket is sleeved and connected with the pump shaft. According to the utility model, the rubber sealing gasket with high elasticity and high wear resistance is adopted to replace a traditional packing wire as the sealing element, thus effectively preventing foreign matters from entering into a gap between the filler box and the pump shaft and reducing the friction of the pump shaft; and simultaneously, the rubber sealing strip is made of a rubber synthetic material with high wear resistance, thus the slurry pump filler sealing device is great in heat-resisting, wear-resisting and corrosion-resisting effects, and can be used for a long time.
Description
Technical field
The utility model relates to slag stock pump technical field of sealing technology, particularly a kind of slag stock pump stuffing seal.
Background technique
The slag stock pump is widely used in industries such as mine, electric power, metallurgy, coal, and it mainly is made up of with shaft sealer the pump housing, pump cover, pump shaft, bearing unit.Shaft sealing is divided into packing seal, pays impeller seals and mechanical seal, because the cost of mechanical seal is high, maintenance is difficulty, so less employing is paid impeller seals and limit by condition, generally also less employing; What generally adopt at present is packing seal, and adopts the packing line to do filler more.But because the fluid density that the slag stock pump is carried is big, impurity is many, particularly the operating mode in ore dressing plant is more abominable, often causes packing line serious wear; Axially reveal serious; Need often to change, increased maintenance worker's activity duration, influence the normal operation of equipment.And the packing line also need steep storage inconvenience with oil immersion.
Summary of the invention
The purpose of the utility model provides a kind of slag stock pump stuffing seal that reduces the maintenance rate, increases the service life.
The purpose of the utility model realizes through following technical proposals:
The slag stock pump stuffing seal of the utility model; Comprise the pump housing, insert pump shaft in this pump housing, therewith the Stuffing box that socket-connects of pump shaft, be located at Sealing in this Stuffing box, through the bolt gland that is connected of Stuffing box therewith; Described Sealing is a rubber gasket, this rubber gasket and described pump shaft socket.
The characteristics of the slag stock pump stuffing seal of the utility model are:
Adopt the rubber gasket that elasticity is big, wear-resisting property is high to replace traditional packing line, stop foreign matter to get in the gap between Stuffing box and the pump shaft effectively, reduce friction pump shaft as Sealing.Because rubber gasket adopts the high rubber composite of wear resistance, have well heat-resisting, wear-resisting, anticorrosion effect simultaneously, can use for a long time.
The utility model is simple in structure, good sealing effect, and long service life is prone to storage, and is easy to maintenance, with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1; The slag stock pump stuffing seal of the utility model; Comprise the pump housing 1, insert pump shaft 5 in this pump housing 1, therewith the Stuffing box 2 that socket-connects of pump shaft 5, be located at Sealing in this Stuffing box 2, through the bolt gland 4 that is connected of Stuffing box 2 therewith; It is characterized in that described Sealing is a rubber gasket 3, this rubber gasket 3 socket-connects with described pump shaft 5.Adopt the rubber gasket 3 that elasticity is big, wear-resisting property is high to replace traditional packing line, stop foreign matter to get in the gap between Stuffing box 2 and the pump shaft 5 effectively, reduce of the friction of slag slurry pump shaft 5 as Sealing.Because rubber gasket 3 adopts the high rubber composite of wear resistance, have well heat-resisting, wear-resisting, anticorrosion effect simultaneously, can use for a long time.
The installation method of the slag stock pump stuffing seal of the utility model is:
Pull down gland, rubber gasket is socketed on the pump shaft, with instrument rubber gasket is pushed in the Stuffing box then, after Stuffing box fills up, gland is pressed on the rubber gasket, use bolt, accomplish and install.Guarantee the sealing effect of rubber gasket.
