Abstract
An oil bearing deflector sealing device of a fixed cold water bearing comprises a bearing, a press cover and a framework oil seal. One end of the bearing is arranged in the press cover, and a framework oil seal is arranged between the bearing and the press cover. The oil bearing deflector has the advantages of effectively preventing a lubrication oil bearing deflector of a fixed cold water pump bearing from leakage, ensuring that the oil level of the bearing is higher than the 1/3 position, enabling bearing balls to be free from oil leakage and not damage equipment and improving safety of the equipment.
Description
Technical field:
The utility model relates to a kind of seal arrangement, relates in particular to a kind of cold water bearing oil shelves seal arrangement of deciding.
Background technique:
Small-sized centrifugal water pump bearing oil shelves generally adopt processing seal groove in the bearing gland, inlay felt and seal, and have the gap between malthoid and the axle; And wear and tear easily, when oil level is high in the bearing, also can leak, decide water supply pump bearing oil shelves oil leakage phenomenon takes place in succession; Bearing oil window oil level is filled it up with oil and was not just had oil in 2～3 hours; Have a strong impact on unit safety stable operation, after the disintegration malthoid in the oil shelves seal groove is replaced by the O RunddichtringO, oil leakage phenomenon takes place again in about after a period of stabilisation 2 day time oil shelves; Decide water supply pump or other pumps of the same type all have oil leakage phenomenon in various degree with reference to other units, have a strong impact on the normal operation of unit.
The model utility content:
What the purpose of the utility model was to provide a kind of simple in structure, easy for installation, good airproof performance decides cold water bearing oil shelves seal arrangement.
The content of the utility model is implemented through following technological scheme: a kind ofly decide cold water bearing oil shelves seal arrangement; Include bearing, gland and outside framework oil seal; Said bearing one end places in the said gland, between said bearing and said gland, is provided with said outside framework oil seal.
Advantage: effectively anti-fastening water supply pump bearing oil oil shelves leak, and guarantee that the bearing oil level remains on more than 1/3, make bearing ball that the oil starvation damage equipment not take place, and improve the Security of equipment.
Description of drawings:
Fig. 1 is the cross-sectional view of the utility model.
Bearing 1, gland 2, outside framework oil seal 3.
Embodiment:
Embodiment 1: (as shown in Figure 1) a kind of decides cold water bearing oil shelves seal arrangement, includes bearing 1, gland 2 and outside framework oil seal 3, and bearing 1 one ends place in the gland 2, between bearing 1 and gland 2, are provided with outside framework oil seal 3.Outside framework oil seal 3 internal diameters under free state are littler than the diameter of axle, promptly have certain " magnitude of interference ".Therefore, after outside framework oil seal 3 was packed between gland 2 and the bearing 1, the helical spring contractile force of the pressure of outside framework oil seal cutting edge and self-tightening produced certain radially tight power to axle, effectively guaranteed the sealing of entire equipment.
Claims (1)
1. decide cold water bearing oil shelves seal arrangement for one kind, include bearing and gland, said bearing one end places in the said gland, it is characterized in that it also includes outside framework oil seal, between said bearing and said gland, is provided with said outside framework oil seal.
