Abstract
The utility model relates to a sealing device for pumps, in particular to a sealing device for an output pump bearing end cover of an open type oil transfer pump. The technical scheme of the sealing device comprises that the sealing device comprises a bearing end cover, a convex packing chamber is processed at the outer side of the bearing end cover, a packing gland is disposed at the outer end of the packing chamber, a rubber sealing ring is mounted in an oil-sealed chamber at the bottom of the packing chamber, and an asbest rope is disposed in an inner cavity of the packing chamber. The sealing device has the advantage that the sealing device resolves the oil leakage of the bearing end cover caused by the non-sealing rubber ring, and has the double sealing effect. Further, the sealing device has fine compressing sealing property and wearing resistance, enables the bearing to have a fine lubricating environment, prolongs the service life of devices, saves engine oil, materials and the like, guarantees clean production, and increases the working efficiency of the devices.
Description
One, technical field:
The utility model relates to a kind of seal arrangement of pump class, particularly relates to a kind of output pump bearing (ball) cover seal arrangement that is applicable to the open type oil transfer pump.
Two, background technique:
At present, generally use middle open type oil transportation centrifugal pump in the oil field, as model is the open type oil transfer pump of 100KY100-250, cross high reason owing to motor and pump decentraction, bearing chamber temperature, make the distortion of bearing (ball) cover rubber seal, damage, aging, cause engine oil leakage, cause bearing stuck because of lacking machine oil, burn out motor when serious, both wasted oil plant, material, polluted environment again.And the on-the-spot O-ring seal of changing must be dismantled motor coupler, bearing parts such as end cap, bearing pressure cap, bearing up and down, and not only time-consuming, but also effort also influences the conveying of crude oil.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of and avoids the seepage of machine oil for bearing (ball) cover increases shaft end seal, reduces the output pump bearing (ball) cover seal arrangement of device damage.
Its technological scheme is: comprise bearing (ball) cover, be processed with the packing chamber of protrusion in the bearing (ball) cover outside, packing gland is installed in the outer end of packing chamber; The rubber seal of packing in the oil sealing chamber of packing chamber bottom, the asbestos rope of packing in the indoor chamber of packing.
The outer end of described packing gland and packing chamber is by being threaded.
The beneficial effects of the utility model are: solved because the cushion rubber blow-by causes the bearing (ball) cover leakage of oil, played the effect of double-sealing.Have good compression sealability and wear resistance, make bearing possess good lubricated environment, prolong service life of equipment, save machine oil, material equal loss, guaranteed cleaner production, improve the working efficiency of equipment.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technological scheme is: comprise bearing (ball) cover 1, be processed with the packing chamber 1 of protrusion in the bearing (ball) cover outside, packing gland 4 is installed in the outer end of packing chamber; The rubber seal of packing in the oil sealing chamber 3 of 1 bottom, packing chamber is at the packing chamber 1 inner chamber asbestos rope of packing into.The outer end of described packing gland 4 and packing chamber 1 is by being threaded.
During use, be processed with the packing chamber 2 of protrusion in the outside of bearing (ball) cover 1, earlier rubber seal is packed in the oil sealing chamber 3 during use, again bearing (ball) cover is enclosed within on the axle, be fixed on the bearing chamber body of output pump by hole 5 usefulness screws, in packing chamber 2, add the 2-3 root then and smear the butter asbestos rope, with spanner that packing gland 4 is first-class, and it is suitable to adjust degree of tightness.
Claims (2)
1, a kind of output pump bearing (ball) cover seal arrangement comprises bearing (ball) cover (1), it is characterized in that: be processed with the packing chamber (2) of protrusion in the bearing (ball) cover outside, packing gland (4) is installed in the outer end of packing chamber; Oil sealing chamber (3) rubber seal of packing in packing chamber (2) bottom is at packing chamber (1) the inner chamber asbestos rope of packing into.
2, output pump bearing (ball) cover seal arrangement according to claim 1 is characterized in that: the outer end of described packing gland (4) and packing chamber (2) is by being threaded.
