Abstract
The utility model discloses a high-sealing capability water pump, which comprises a pump body, an impeller, a pump shaft part, and a sealing device, wherein, the pump shaft part comprises a pump shaft and a pump shaft supporting shell; the pump shaft is supported on the pump shaft supporting shell by a group of bearings; the impeller is arranged on the right end of the pump shaft; the sealing device is arranged between the impeller and the pump shaft supporting shell; the sealing device is the combination of rubber sealing and mechanical sealing, that is to say, cup packing and an O-shaped sealing ring are arranged between the pump shaft and the pump shaft supporting shell; the mechanical sealing is arranged between the impeller and the pump shaft supporting shell; because the combination of the rubber sealing and the mechanical sealing is adopted between the pump shaft part and the pump body, and a double-layer anti-leakage structure is arranged between the pump body and the pump shaft part, even when a small amount of water in the pump body leaks from the mechanical sealing, the rubber sealing structure can block the water to enable the water in the pump body to be hard to leak, and thereby, the sealing capability of the water pump is enhanced.
Description
One, technical field:
The utility model relates to a kind of water pump, and what refer more particularly to is self-priming pump and centrifugal pump.
Two, background technique:
In self-priming pump that generally uses at present and centrifugal pump, all contain the pump housing, pump shaft parts, impeller and seal arrangement, described pump shaft parts comprise pump shaft and pump shaft supporting shell again, impeller is installed in the right-hand member of pump shaft, seal arrangement is arranged between pump shaft supporting shell and the impeller, and be sleeved on the pump shaft, the structure of described sealing dress mainly contains following several:
1, pure mechanical seal structure: promptly between impeller and pump shaft supporting shell mechanical seal is installed, this mechanical seal is WM104 type series mechanical sealing configuration in the JB1472-75 NBS;
2, pure cup packing structure: promptly between pump shaft and pump shaft supporting shell, adopt outside framework oil seal to seal;
3, packing seal structure: promptly between pump shaft and pump shaft supporting shell, adopt packing seal structure to seal.All there is the insecure defective of water-stop in actual use in the simple self-priming pump or the centrifugal pump of above-mentioned a certain sealing configuration of adopting, not only have influence on the service behaviour of water pump, and the water that infiltrates from the pump housing also can soak the block bearing in the decorations pump shaft parts, thereby influences the working life of water pump.
Three, summary of the invention:
Goal of the invention of the present utility model is to provide a kind of water pump of high leak tightness, and to overcome existing water pump above shortcomings, the utility model is to realize the foregoing invention purpose by following technical solution:
The water pump of high leak tightness described in the utility model comprises the pump housing, impeller, pump shaft parts and seal arrangement, the pump shaft parts comprise pump shaft and pump shaft supporting shell again, pump shaft is bearing on the pump shaft supporting shell by one group of bearing, impeller is installed in the right-hand member of pump shaft, seal arrangement is arranged between impeller and the pump shaft supporting shell, and be sleeved on the pump shaft, described seal arrangement is the combination of rubber seal and mechanical seal, promptly between pump shaft and pump shaft supporting shell, be provided with rubber seal, between impeller and pump shaft supporting shell, be provided with mechanical seal.
As to further improvement of the utility model, described rubber seal is cup packing or packing seal, and described mechanical seal is the sealing of WM104 type series mechanical.
As to further improvement of the utility model, described cup packing is skeleton rubber oil sealing or exoskeletal rubber oil sea, promptly is provided with skeleton rubber oil sealing or exoskeletal rubber oil sea between pump shaft and pump shaft supporting shell; Described packing seal is the O RunddichtringO, promptly is provided with 1～3 road O RunddichtringO between pump shaft and pump shaft supporting shell.
Owing between the pump shaft parts and the pump housing, take the combination of rubber seal and mechanical seal, double-deck impermeable structure has been arranged between the pump housing and the pump shaft parts, when even the low amounts of water in the pump housing is come from the mechanical seal infiltration, also have rubber sealing structure that it is blocked, make the water in the pump housing be difficult to seepage, thereby improved the sealing of water pump.
Four, description of drawings: Fig. 1 is a kind of structural representation of the present utility model; Among the figure: the 1-pump housing; The 2-impeller; 3-pump shaft parts; The 31-pump shaft; 32-pump shaft supporting shell; The 33-bearing; The 4-reinforced seal; 5-mechanical seal.
