Abstract
The utility model discloses a highly-effectively self priming pump, which comprises a motor (1), a pump body (2), a pump shaft (3), a liquid output pipe (4), a liquid inlet pipe (5) and a seal device,wherein the seal device is a mechanical seal combined device, a static ring seat (6) and a motor supporting stand (7) are welded into a whole, a static ring gland (8) and the static ring seat (6) arefastened and connected, a seal ring (11) is arranged between a static ring (9) and a dynamic ring (10) and is sleeved on the pump shaft (3), the inner cavity of the dynamic ring (10) is provided witha resilient (12), the lower portion of the dynamic ring (10) is provided with a locking sleeve (13), and the locking sleeve (13) is connected and sleeved on the pump shaft (3) through screw threads.With the structure, the highly-effective self priming pump can lower the power consumption of the motor, and improves the working efficiency of the self priming pump, thereby lowering power consumption cost, and reaching the energy-saving effect.
Description
Technical field
The utility model relates to a kind of pump, especially relates to a kind of high-efficiency self-priming pump that is used for fed sheet of a media.
Background technique
At present, be applied in industries such as petrochemical industry, smelting, papermaking, medicine, food processing and often adopt self-priming pump to carry out blowdown work, self-priming pump is when work, and the current of priming reservoir enter from liquid inlet pipe, flow out from drain pipe, can have the anti-leak problem on the current direction in the liquid storage room.Existing self-priming pump seal arrangement is mainly combined by sealing impeller, closed chamber, sealed cover, and the sealing impeller set is contained on the pump shaft, when pump shaft rotates, drive seal impeller with the reciprocal rotation of running wheel, thereby play seal action.But this seal arrangement has increased motor load, loss power of motor, make self-priming pump efficient reduce, electric cost increases.
Summary of the invention
The purpose of this utility model provides a kind of high-efficiency self-priming pump, in order to solve the technical problem that efficient is low, power consumption is big that original self-priming pump seal arrangement causes.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises motor, the pump housing, pump shaft, drain pipe, liquid inlet pipe and seal arrangement, described seal arrangement is the mechanical seal composite set, wherein stationary seat and electric machine support are welded as a whole, seal end plate connects with stationary seat is fastening, be provided with seal ring between stationary ring and the rotating ring and be sleeved on the pump shaft, the rotating ring inner chamber is provided with elastic component, the rotating ring below is provided with lock sleeve, and lock sleeve is sleeved on the pump shaft with scyewed joint.
The said structure that the utility model adopts, the seal arrangement of the sealing impeller type that self-priming pump is traditional changes the mechanical seal composite set that uses dynamic and static ring into, can reduce the power of motor loss, improve the working efficiency of self-priming pump, thereby reduce electric cost, reach energy-saving effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Embodiment
By accompanying drawing as can be known, this high-efficiency self-priming pump comprises motor 1, the pump housing 2, pump shaft 3, drain pipe 4, liquid inlet pipe 5 and seal arrangement, described seal arrangement is the mechanical seal composite set, wherein stationary seat 6 is welded as a whole with electric machine support 7, seal end plate 8 and 6 fastening connections of stationary seat, seal end plate 8 can compress stationary ring 9, be provided with seal ring 11 between stationary ring 9 and the rotating ring 10 and be sleeved on the pump shaft 3, rotating ring 10 inner chambers are provided with elastic component 12, elastic component generally adopts pressure spring, rotating ring 10 belows are provided with lock sleeve 13, and lock sleeve 13 is sleeved on the pump shaft 3 with scyewed joint.Stationary ring can adopt carbofrax material to make, and rotating ring can adopt alloy just to make.During self-priming pump work, the priming reservoir current enter from liquid inlet pipe, flow out from drain pipe, when the pump shaft impeller is rotated, closely cooperating between the dynamic and static ring can be played the effect of leak-tight seal well, substitutes the seal arrangement of the traditional sealing impeller type of self-priming pump, can reduce the power of motor loss.The utility model is with the described scope of soverlay technique scheme; and the various distortion of claim scope and equivalence variation; under the prerequisite that does not depart from technical solution of the present utility model, any modification or improvement that those skilled in the art that the utility model is done realize easily all belong to the utility model scope required for protection.
