Abstract
The invention relates to a water pump with a T-shape seal ring. The water pump comprises a base, a pump body arranged on the base and a motor for driving. An input shaft on the pump body penetrates an end cover to be connected with an output shaft of the motor, and the T-shape seal ring is arranged on the input shaft attached to the inner wall of the end cover. According to the water pump with the T-shape seal ring, the T-shape seal ring with certain elasticity is added between the input shaft and he inner wall of the end cover, so that micro axial wobbling of the input shaft can be born, the pump body seal performance is greatly improved, the pressure leakage probability is minimized, and the water pump service life is effectively prolonged.
Description
Technical field
The present invention relates to the field of water pump, especially a kind of water pump with T-shaped seal ring.
Background technique
Water pump is indispensable equipment in the daily production of people, and the sealability of the pump housing in the length in the working life of water pump and the height of performance and water pump is closely related, especially the input shaft end cap place of the pump housing, existing water pump generally adopts O type rubber ring to seal this position, and in the pump housing under the environment of high hydraulic pressure, O type rubber ring can occur aging, the leakage that causes the pump housing is pressed, the input shaft of water pump has axial small vacillating when work simultaneously, can accelerate the wearing and tearing of O RunddichtringO, if things go on like this, not only affect the working efficiency of water pump, and can greatly increase the rate of fault of water pump.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the problem of above-mentioned middle existence, provide a kind of water pump with T-shaped seal ring, good seal performance, the difficult leakage pressure that occurs.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water pump with T-shaped seal ring, comprise base and be arranged on the pump housing on base and the motor for driving, input shaft on the described pump housing is through end cap and being connected with the output shaft of motor by coupling, and on described input shaft and the inwall place of being close to end cap is provided with T-shaped seal ring.
The invention has the beneficial effects as follows: described a kind of water pump with T-shaped seal ring, between input shaft and end cap inwall, set up and there is certain flexible T-shaped seal ring, can not only bear small axially the vacillating of input shaft, greatly improved the sealability of the pump housing simultaneously, the possibility that leakage is pressed is down to minimum, has effectively extended the working life of water pump.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the overall structure schematic diagram of a kind of water pump with T-shaped seal ring of the present invention;
Fig. 2 is the partial sectional view of a kind of water pump with T-shaped seal ring of the present invention.
Accompanying drawing acceptance of the bid note is described below: 1, base, 2, the pump housing, 2-1, input shaft, 2-2, end cap, 2-3, mechanical seal, 3, motor, 4, coupling.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of water pump with T-shaped seal ring as depicted in figs. 1 and 2, comprise base 1 and be arranged on the pump housing 2 on base 1 and the motor 3 for driving, input shaft 2-1 on the pump housing 2 is connected with the output shaft of motor 3 through end cap 2-2 and by coupling 4, and input shaft 2-1 goes up and the inwall place of being close to end cap 2-2 is provided with T-shaped seal ring 2-3.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
