Description
Technical field
The utility model relates to a kind of seal arrangement, and a kind of better tapered sleeve stationary machine sealing of sealing effect that is used for various gear pumps, multistage centrifugal fire water pump or fire water pump particularly is provided.
Background technique
Gear pump or multistage pump in use have more existing leakage of oil, get rid of oily phenomenon, domestic general employing rubber seal sealing, seal by the graphite soft packing in addition, but, because gear pump or multistage pump in use rotate caused friction, be easy to make above-mentioned sealing material to damage, can find that thus above-mentioned seal arrangement exists working life short, easily reveal shortcoming such as maintenance load is big; At present, multistage centrifugal pump generally adopts spiral sealing device on the market, but because its general skeleton oil seal that adopts, aging easily and wearing and tearing are easy to produce the phenomenon of getting rid of oil, leakage of oil;
At present, the mechanical seal on the market adopts jackscrew formula localization method to fix more, and it in use is difficult for installation and removal, and jackscrew is loosening easily, causes seal failure, the maintenance process difficulty is increased, and its sealing effect is not fine.
The model utility content
The utility model purpose be to provide a kind of sealing effect better, make things convenient for installing/dismounting, tapered sleeve stationary machine sealing easy to maintenance.
In order to achieve the above object, the utility model provides a kind of tapered sleeve stationary machine sealing, it is set on the pump shaft, and be arranged in the pump housing, this tapered sleeve stationary machine sealing comprises fixed cover, this fixed cover is located on the pump shaft, this fixed cover is provided with spring, the other end of this spring is equipped with the rubber sleeve anchor ear, and the rubber sleeve anchor ear is set on the rubber sleeve, and this rubber sleeve is stepped, and be arranged with the L style ferrules, the other end of this L style ferrules is inlaid with rotating ring, this rotating ring stationary seat that reclined, and this stationary seat is fixed in the pump housing by jump ring, also can fix by flange, wherein: the inner edge surface of described fixed cover is the conical surface, and this pump shaft is provided with the tapering that matches with this conical surface, and this fixed cover snap fit is on pump shaft.
The outer edge surface of described stationary seat offers circular groove, is arranged with the O RunddichtringO in this circular groove.
Described stationary seat is inlayed near the surface of rotating ring and is provided with carbide ring.
Described rotating ring is the graphite rotating ring.
Because to have adopted the inner edge surface with fixed cover is the conical surface to the utility model, and snap fit makes this tapered sleeve stationary machine sealing have following beneficial effect on pump shaft and in the structure of the sheathed O RunddichtringO of the outer edge surface of stationary seat:
1, good sealing effect;
2, pump does not need to disintegrate, and both replaceable sealing is easy for installation and maintenance.
Description of drawings
Fig. 1 is the utility model embodiment's an overall structure schematic representation.
