Abstract
The utility model relates to a cooling water cavity inlet and outlet structure for a vertical shaft mixing pump, which comprises a bearing body (20). The bearing body (20) has openings at both the upper end and the lower end; the two openings are mutually separated; the upper end surface of the bearing body (20) and a bearing cover (30) are matched in a sealed mode to form an oil chamber (100); and the lower end surface of the bearing body (20) is sealed by a steel plate to form a cooling water cavity (70). The utility model has the advantages that good lubricating effect of the bearing can be ensured; because of the external connection of the cooling water, the phenomenon of bearing heating in the operating process can be completely avoided; and the bearing is ensured to be safely and reliably lubricated.
Description
Technical field
The utility model relates to a kind of vertical shaft and mixes pump, and the cooling water chamber that relates in particular to this pump is into and out of structure.
Background technique
Mix pump for various vertical shaft, can produce axial force (axial hydraulic thrust and rotatable parts weight) during pump operation can bear by motor, also can be born by the thrust bearing part of pump itself.
As seen from Figure 1: cooling water chamber and grease chamber are sealed by bearing cap 3 and first seal ring 4 and second seal ring 5 and separate.Bearing cap second seal ring 5 bottom can only guarantee with size when mounted, and can't observe the situation of installation, therefore second seal ring 5 damages in installation process and can't find, cooling water enters in the bearing lubrication grease chamber and causes lubrication failure when it installs the pump use of damage back, can only termination of pumping overhaul; Again still can't predict the situation that second seal ring 5 is installed after changing seal ring and installing once more, bearing is in the risk of damaging at any time.Among the figure: selfaligning roller bearing 1, bearing support 2, thrust roller bearing 6, cooling water chamber 7, feed-water end 8, waterexit end 9, grease chamber 10.
This bearing support finds that in use cooling water can enter the grease chamber, causes damage of bearings, causes shutdown loss, for thorough head it off, proposes novel bearing support structure.
Summary of the invention
The utility model technical issues that need to address have provided a kind of vertical shaft and have mixed cooling water chamber that pump uses into and out of structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: bearing support; Described bearing support is at both ends open up and down, and two openings are separate; Being sealed and matched at bearing support upper-end surface and bearing cap forms the grease chamber, forms cooling water chamber in the bearing support lower end surface with the steel plate sealing.
Compared with prior art, the beneficial effects of the utility model are: can guarantee the good lubrication of bearing, and external cooling water, the phenomenon that can avoid the operation process middle (center) bearing to generate heat is fully guaranteed safe and reliable the lubricating of bearing.
Description of drawings
Fig. 1 is a vertical type pump bearing body structure schematic representation in the prior art;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: bearing support 20; Described bearing support 20 is at both ends open up and down, and two openings are separate; Being sealed and matched at bearing support 20 upper-end surfaces and bearing cap 30 forms grease chamber 100, forms cooling water chamber 70 in bearing support 20 lower end surfaces with the steel plate sealing;
Described bearing support 20 lower end surfaces form cooling water chamber 70 by 50 sealings of first seal ring with the steel plate sealing;
Described being sealed and matched at bearing support 20 upper-end surfaces and bearing cap 30 forms grease chamber 100 by 40 sealings of second seal ring.Among the figure: feed-water end 80, waterexit end 90, selfaligning roller bearing 1, thrust roller bearing 6.
The utility model is revised the bearing support structure, and the opening direction of cooling water chamber is changed into the lower end surface of bearing support, and with the sealing gasket sealing, the grease chamber seals with sealing gasket.Sealing is more reliable after the architecture advances, more can guarantee can not enter cooling water in the grease chamber, and the Conncetion cimension of bearing part and other parts and old structure are identical., can directly dismantle the back new structure is installed at the bearing body part that uses for, cooling line system and miscellaneous part do not need dismounting, and maximum saving is artificial.
The utility model is in work, and lubricant oil rotates in the grease chamber, has not only produced heat but also the possibility of leakage is arranged.The grease chamber seals with seal ring, has guaranteed that lubricant oil does not leak, and feeds cooling water in cooling water chamber, takes away grease chamber's heat, and cooling water enters in the bottom, and flow out on top, makes bearing support fully cool off, and cooling water seals with sealing gasket, guarantees that cooling water does not outflow.This kind working method is operation fully both, makes cooling water and oil isolate fully again, can not exist cooling water to enter the risk that the grease chamber causes damage of bearings.
Claims (3)
1. a vertical shaft is mixed cooling water chamber that pump uses into and out of structure, comprising: bearing support (20); It is characterized in that: described bearing support (20) is at both ends open up and down, and two openings are separate; Being sealed and matched at bearing support (20) upper-end surface and bearing cap (30) forms grease chamber (100), forms cooling water chamber (70) in bearing support (20) lower end surface with the steel plate sealing.
