The center lines of the two semi-circular sealing grooves are parallel, and the distance between the center lines of the two semi-circular sealing grooves is equal to the distance between the center lines of the two cylinder sealing grooves. The depth of the semi-circular sealing groove plus the depth of the cylinder sealing groove is greater than the diameter of the sealing ring so that the sealing ring can be pre-compressed and deformed.
[0007] In the above structure, an air pump outlet is provided in the middle part of the cylinder block.
[0008] In the above structure, screw holes are provided at the four corners of the upper cover and the four corners of the lower cover so that the upper cover and the lower cover can be connected by bolts.
[0009] In the above structure, the upper cover and / or lower cover are provided with two water pipe interfaces to allow the cooling water to exchange with the water in the sealed space formed by the cylinder block, upper cover, lower cover, two sealing rings, and two sealing gaskets.
[0010] In the above structure, the two semi-circular sealing grooves are provided with rounded corners to accommodate the deformation of the sealing ring.
[0011] In the above structure, the diameter of the semi-circular sealing groove is larger than the diameter of the cylinder sealing groove to facilitate assembly.
[0012] The technical advantages of this invention are as follows: by setting an upper cover and a lower cover, the cylinder body, upper cover, and lower cover form a sealed space. The sealed space is filled with water to cool the cylinder body, resulting in high cooling efficiency. This ensures that the cylinder body temperature will not rise and affect the operation of the air pump even after long-term use.
