Abstract
The utility model discloses a diesel engine cylinder block water jacket structure, comprising a water fender, a water inlet hole, a transition rounded corner, a cylinder hole water jacket, a lower cylinder hole, a cone-shaped water jacket structure, an upper drainage hole at an air exhaust side of a cylinder cap and an upper drainage hole at an air inlet side of the cylinder cap. The utility model is characterized in that the cylinder hole water jacket structure is designed to a cone water jacket structure with a big upper part and a small lower part according to the principle of a jet tube, so that chilled water is compelled to accelerate flow speed when flowing from bottom to top. The lower cylinder hole moves upward one height, so that the cylinder hole water jacket shortens one height, the support for the middle part of a cylinder jacket is strengthened, and the vibration and the deformation of the middle part of the cylinder jacket are reduced. The water inlet hole is a tangential water inlet device, so that water stream around the cylinder sleeve is uniform. The point of the water inlet hole is provided with the water fender and the transition rounded corner, so that a portion of chilled water converts to the air exhaust side. The position of the upper drainage hole at the air exhaust side of the cylinder cap is lower, and the position of the upper drainage hole at the air inlet side of the cylinder cap is higher, so that the stream velocity at the air exhaust side is accelerated, and the cavitation erosion of the cylinder jacket wall at the air exhaust side is efficiently controlled. The utility model has the advantages of overcoming the cavitation erosion of the diesel engine cylinder jacket with large power and extending the service life of the diesel engine.
Description
Technical field
The utility model relates to a kind of water jacket structure of diesel cylinder block, relates in particular to a kind of water jacket structure of diesel cylinder block that can suppress cylinder liner cavitation.
Background technique
Existing diesel engine is continually strengthened, and the mechanical load of cylinder sleeve and heat load are also increasing, has caused the serious cavitation pitting of cylinder sleeve thus, and engine life does not reach the requirement of expection.
Summary of the invention
The purpose of this utility model is to provide a kind of water jacket structure of diesel cylinder block that can suppress cylinder liner cavitation.Comprise by water hole on water hole, the air inlet side cylinder cap on manger board, water inlet, knuckle, cylinder hole water jacket, following cylinder hole, taper jacket structure for water, exhaust side, the exhaust side cylinder cap, cylinder hole water jacket is the big down fine taper structure that goes up, cylinder hole water jacket external diameter tangent direction has the water inlet, and there are grade a water plate and a knuckle in the outlet limit of water inlet.Cylinder hole under under the water jacket of cylinder hole being, the connection mouth of water hole and water jacket is opened the bottom at water jacket on the exhaust side cylinder cap, and the connection mouth of water hole and cylinder sleeve is opened the top at water jacket on the air inlet side cylinder cap.The advantage that the utility model compared with prior art has is to have overcome high-power, highly-intensified diesel engine cylinder liner cavitation fault, has prolonged the life-span of diesel engine.
Description of drawings
Block jacket structure of the present utility model is such:
Fig. 1 is a block jacket structure plan view.
Fig. 2 is the A-A sectional view among Fig. 1.
Fig. 3 is the B-B sectional view among Fig. 1.
Among Fig. 1～Fig. 3, manger board (1), water inlet (2), knuckle (3), cylinder hole water jacket (4), water hole (9), air inlet side (10) on water hole (8), the air inlet side cylinder cap on cylinder hole (5), taper jacket structure for water (6), exhaust side (7), the exhaust side cylinder cap down
Embodiment
With reference to Fig. 1～shown in Figure 3, a kind of water jacket structure of diesel cylinder block of the utility model, its structure comprises: manger board, water inlet, knuckle, cylinder hole water jacket, following cylinder hole, taper jacket structure for water, water hole on the exhaust side cylinder cap, water hole on the air inlet side cylinder cap.Embodiment is such: move on the following cylinder hole (5), shorten cylinder hole water jacket (4) highly, strengthen the supporting of cylinder sleeve middle part, reduced the vibration deformation at cylinder sleeve middle part.Cylinder hole water jacket (4) structure applications the jet pipe principle, be designed to down go up little taper jacket structure for water (6) greatly, accelerate flow velocity when forcing cooling water from the bottom up.The tangential water inlet in water inlet (2) makes the cylinder sleeve ambient water even.The place increases manger board (1) in the water inlet, increases knuckle (3), makes part cooling water changed course exhaust side (7).Position, water hole on the exhaust side cylinder cap (8) is lower, and position, water hole (9) is higher on the air inlet side cylinder cap, has accelerated exhaust side (7) water velocity, has suppressed the cavitation pitting of exhaust side cylinder bore wall effectively.
Claims (3)
1. water jacket structure of diesel cylinder block, comprise manger board, the water inlet, knuckle, cylinder hole water jacket, following cylinder hole, the taper jacket structure for water, water hole on the exhaust side cylinder cap, water hole on the air inlet side cylinder cap, it is characterized in that cylinder hole water jacket (4) is the big down little taper jacket structure for water (6) of, the external diameter tangent direction of cylinder hole water jacket (4) has water inlet (2).
2. water jacket structure of diesel cylinder block according to claim 1 is characterized in that water inlet (2), on the outlet limit of water inlet manger board (1) is arranged, and knuckle (3) is arranged.
3. water jacket structure of diesel cylinder block according to claim 1 is characterized in that position, water hole on the exhaust side cylinder cap (8) is lower than position, water hole (9) on the air inlet side cylinder cap.
