Abstract
The utility model discloses a centrifugal pump impeller and wear ring sealing device, which consists of an impeller and a wear ring. The utility model is characterized in that a mechanical seal movable ring is arranged at the outer edge of the water inlet of the impeller; a mechanical seal static ring is arranged in the wear ring; the mechanical seal movable ring is inserted into the wear ring and contacts the mechanical seal static ring. The utility model has the advantages that the prior clearance fit of the impeller and the wear ring is changed into abrasion fit without gap after being assembled, thus increasing the pumping height of the water pump, improving the self-pumping performance, reducing the refluence of the high-pressure water, and greatly improving the working efficiency of the water pump; the water pump can be started without bearing any load, and it is unnecessary to fill water into the pump, thus saving the power for starting up the pump.
Description
Technical field
The utility model is particularly related to a kind of centrifugal pump impeller and mouth ring sealing device.
Background technique
At present, the method that centrifugal pump impeller and control ring seal adopted is the Spielpassung that impeller and choma is processed into 0.3～0.5mm, though this method can play certain sealing effect, but it is because also gapped between impeller and the choma, can produce backflow during centrifugal pump work, thereby influenced the performance of water pump, particularly reduced the working efficiency of water pump; In addition, impeller and choma are gapped will pour water earlier when making starting mode of pump, causes the water pump starting under load, has increased the resistance that starts.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above technology, a kind of vacuum height that sucts that improves water pump is provided, strengthens self-priming performance, reduce and reflux, improve the centrifugal pump impeller and the mouth ring sealing device of pump working efficient, the sealing device can make water pump realize zero load startup.
The utility model is achieved in that it comprises impeller and choma, its special way is: the water intake outer rim at impeller is provided with mechanical sealing linkage ring, be provided with mechanical sealing static ring in choma, described mechanical sealing linkage ring is inserted in the choma and with mechanical sealing static ring and contacts.
Above-mentioned centrifugal pump impeller and mouth ring sealing device are provided with ladder at the choma inwall, and described mechanical sealing static ring leans on ladder, to guarantee sealing effect.
Above-mentioned centrifugal pump impeller and mouth ring sealing device are provided with the O RunddichtringO, to guarantee sealing effect between mechanical sealing linkage ring and impeller intake outer rim.
Above-mentioned centrifugal pump impeller and mouth ring sealing device are provided with the O RunddichtringO, to guarantee sealing effect between mechanical sealing static ring and choma inwall.
The utility model has the advantages that: the Spielpassung of original impeller and choma is changed into the rotating ring of mechanical seal and the frictional fit between the stationary ring, it is very close to each other that the back is installed, can improve the vacuum height that sucts of water pump, strengthen self-priming performance, reduce the backflow of high pressure water, improve the working efficiency of water pump greatly; Make water pump realize zero load startup, need not pour water during startup, save the power when starting.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the scheme of installation of Fig. 1.
Embodiment
As shown in the figure, the utility model comprises impeller 1 and choma 2, water intake outer rim at impeller 1 is provided with mechanical sealing linkage ring 3, be provided with two ladders at choma 2 inwalls, ladder place, middle part in choma 2 is installed with mechanical sealing static ring 4, and mechanical sealing linkage ring 3 is inserted in the choma 2 and leans on mechanical sealing static ring 4.Being respectively equipped with O RunddichtringO 5 between mechanical sealing linkage ring 3 and the impeller 1 water intake outer rim and between mechanical sealing static ring 4 and choma 2 inwalls, to guarantee sealing effect.
During installation, impeller 1 is installed on the pump shaft, the water inlet that choma 2 is installed to impeller 1 in the pump housing gets final product.
