Detailed Description

The embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, and the embodiments described below by referring to the drawings are exemplary and intended to explain the present invention so that the technical solutions of the present invention can be more easily understood and grasped, and cannot be construed as limiting the present invention.

Examples

The utility model provides a left pump case of high strength, refer to fig. 1, it is shown in fig. 2 and fig. 3 to refer to, the utility model discloses a left pump case of high strength, including casing 1, be equipped with discharge port 2 on one side of casing 1, be equipped with the pump chamber 3 that open side down in the casing 1, the top of pump chamber 3 is equipped with buffer slot 4, one side that pump chamber 3 is close to discharge port 2 is equipped with first side buffer slot 5, discharge port 2 is through first side buffer slot 5 and pump chamber 3 intercommunication, one side that discharge port 2 was kept away from to pump chamber 3 is equipped with second side buffer slot 6, first side buffer slot 5, go up buffer slot 4 and second side buffer slot 6 and communicate in proper order.

First side buffer slot 5, go up buffer slot 4 and second side buffer slot 6 and communicate in proper order and form a buffer channel, after oil enters into pump chamber 3, oil at first can strike second side buffer slot 6, strike last buffer slot 4 afterwards, strike first side buffer slot 5 again at last, make oil reduce the velocity of flow by a wide margin at the both ends of speed sudden change (when getting into pump chamber 3 promptly and when discharging pump chamber 3), speed is more stable when making oil discharge, the impact force to the pump case reduces, the life of pump case has been improved, the pump case easy cracking and the easy scheduling problem that warp has been solved, have increase of service life and reform transform beneficial effect such as simple.

The bottom of the upper buffer groove 4 is provided with a reinforcing convex shoulder 7, one end of the reinforcing convex shoulder 7 extends towards the first side buffer groove 5 and is connected with the bottom of the first side buffer groove 5, and the other end extends towards the second side buffer groove 6 and is connected with the bottom of the second side buffer groove 6. Strengthen the design of convex shoulder 7 and make first side dashpot 5, go up the intensity of dashpot 4 and second side dashpot obtain effectual promotion, strengthen moreover convex shoulder 7 will go up dashpot 4, the centre of part first side dashpot 5 and part second side dashpot 6 and cut off for oil can be difficult to scurry in first side dashpot 5, go up dashpot 4 and second side dashpot 6 in disorder, and is more stable.

The groove walls on the two sides of the upper buffer groove 4 are respectively provided with an expanding groove 8 extending towards the outer side direction of the groove walls on the two sides. The design of the expansion groove 8 effectively increases the holding capacity of the upper buffer groove 4, and further improves the buffering capacity of the upper buffer groove 4.

The bottom of the expansion groove 8 is obliquely arranged and gradually increases from top to bottom with the distance between the bottom of the upper buffer groove 4 and the groove wall. This design makes the degree of depth of expanding groove 8 lean on the lower extreme more deeply, and then makes to expand groove 8 and can hold oil the very first time, and buffer slot 4 promotes the buffer capacity in the help.

The juncture between the groove bottom of the expansion groove 8 and the groove wall of the upper buffer groove 4 adopts circular arc transition. The arc transition design can effectively reduce the influence on the flow direction of the oil caused by the junction between the tank bottom of the expansion tank 8 and the tank wall of the upper buffer tank 4, and reduce the possibility of oil fleeing.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
