Detailed Description
The following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
As described in the background art, the water seal can exert a good sealing effect only when working under a certain water circulation amount, for example, a vehicle-mounted water pump, the water seal is sealed by a working surface between a movable ring rotating along with an impeller and a stationary ring fixed on a pump shell, the working surface ensures that water always flows, on one hand, the flowing water can take away heat generated by friction of the working surface, a sealing member matching the movable ring and the stationary ring is not ablated and damaged, on the other hand, the flowing water can continuously wash the working surface, so that foreign matters generated by the friction of the working surface and the foreign matters contained in the water are washed away, and therefore, the foreign matters in the working surface are ensured to be discharged. The existing vehicle-mounted water pump does not have a water seal with water circulation, foreign matters on the working surface of the water seal cannot be discharged, and heat cannot be dissipated, so that the water seal is damaged in advance and is leaked, and water generated by leakage flows into a circuit inside a vehicle body to cause accidents such as short circuit and the like.
The first embodiment is as follows:
as shown in figure 1, the pump shell facilitating water seal water circulation comprises a pump shell 1, wherein the pump shell 1 is provided with a water seal mounting seat, a water groove A2 is arranged on one side of the pump shell 1 close to an impeller, and a water groove A2 is directed to the central axis of the pump shell 1 from an outlet volute chamber of the pump shell 1. The axis of the water tank A2 is tangential to the circumferential direction of the impeller.
According to the water potential pressure distribution when the impeller works, taking a centrifugal pump as an example: the edge of the impeller is a high-pressure area, water flows to an outlet volute chamber of the pump shell 1 clockwise or anticlockwise (depending on visual angle direction) along the circumferential direction from the central axis of the pump shell 1 under the driving of the impeller, a part in the outlet volute chamber can flow around a water seal along a water channel A2 and then flows out through a water seal drainage hole (not marked in the drawing) reserved on the pump shell to form water circulation, so that a good working environment of the water seal is ensured.
Taking fig. 1 as an example, under the view angle of fig. 1 (the direction from the inner side of the pump shell to the water seal mounting seat), the impeller runs along the counterclockwise direction, the water channel a2 points from the outlet volute chamber of the pump shell 1 to the central axis of the pump shell 1, part of water flows to the water seal along the water channel a2, foreign matters on the water seal working surface are washed, the water temperature of the water seal is reduced, the foreign matters flow out from the water seal drainage hole reserved on the pump shell 1, the water flowing out is connected with the drainage pipe, and the short circuit of the vehicle-mounted electrical appliance caused by the water drainage is avoided.
Example two:
as shown in fig. 2, the water tanks B21 are three groups, each group of water tanks B21 is directed to the central axis of the pump casing 1 by the outlet volute of the pump casing 1, the three groups of water tanks B21 are evenly distributed on the pump casing 1, and the axis of each group of water tanks B21 is tangential to the circumferential direction of the impeller.
Taking fig. 2 as an example, under the view angle of fig. 2 (the direction from the inner side of the pump shell 1 to the water seal mounting seat), the impeller runs along the counterclockwise direction, the three groups of water channels B21 point from the outlet volute chamber of the pump shell 1 to the central axis of the pump shell 1, part of water flows to the water seal along the water channel B21, foreign matters on the water seal working surface are washed, the water temperature of the water seal is reduced, the foreign matters flow out from the water seal drainage hole reserved on the pump shell 1, the water flowing out is connected with the drainage pipe, and the short circuit of the vehicle-mounted electrical appliance caused by water drainage is avoided.
In this way, the number of the water tanks is larger, and the flow rate of the circulating water introduced into the water seal is larger than that of the first embodiment, so that the water seal device is suitable for the environment with higher water seal temperature.
Example three:
as shown in fig. 3, the water tanks C22 have three sets, each set of water tanks C22 is formed by directing the outlet volute chamber of the pump housing 1 to the water seal mounting seat of the pump housing 1 at a certain angle without passing through the central axis of the pump housing 1, the three sets of water tanks C22 are uniformly distributed on the pump housing 1, and the axis of each set of water tanks C22 forms a certain angle with the circumferential direction of the impeller.
Taking fig. 3 as an example, under the view angle of fig. 3 (the direction from the inner side of the pump case 1 to the water seal installation seat), the impeller runs along the counterclockwise direction, the three groups of water channels C22 are directed to the water seal installation seat of the pump case 1 at a certain angle from the outlet volute chamber of the pump case 1 without passing through the central axis of the pump case 1, a part of water flows to the water seal along the three groups of water channels C22, after foreign matters on the water seal working surface are washed and the water seal temperature is reduced, the foreign matters flow out from the water seal drainage holes reserved on the pump case 1, the water flowing out is connected with the drainage pipes, and the short circuit of the vehicle-mounted electrical appliances caused by water drainage is avoided.
In this way, the axis of each group of water channels C22 forms a certain angle with the circumferential direction of the impeller, and compared with the tangency between the first embodiment and the second embodiment, the angle of the water channel in this embodiment is more favorable for the introduction of water, the flow rate of the water in the water channel can be accelerated to a certain extent, and the flow rate of the circulating water introduced into the water seal is indirectly larger than that in the second embodiment, so that the water seal device is suitable for the environment with higher water seal temperature.
Example four:
a water pump has a pump housing 1, and the structure of the pump housing 1 adopts any one of the three embodiments. The number of water tanks on the pump housing 1 is not limited, and the pump housing 1 is formed by machining or casting.
The water inlet faces to the axial direction of the impeller, and the water outlet faces to the circumferential tangent direction of the impeller.
Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
