Cylinder

Category:

Unlike non-standard oil cylinders, the end cover is equipped with intake and exhaust ports, and a buffering mechanism is installed on the end cover. The sealing ring and dust-proof ring are placed on the side cover of the rod to prevent air leakage from the piston rod and to keep external dust from entering the cylinder. A guiding sleeve is installed on the side end cover of the rod to improve the guiding accuracy of the cylinder, allowing the piston rod to bear a small amount of lateral load, reducing the bending of the piston rod, and extending the service life of the cylinder. The cylinder body of the internal combustion engine has a cavity for the piston. This is the trajectory of the piston movement, where gas burns and expands. The cylinder wall can also dissipate some of the explosive waste heat from the gas, keeping the engine at a normal operating temperature. The cylinder types include integral casting and single-piece casting. Single-piece casting can be divided into dry type and wet type. When the cylinder and cylinder body are cast as a whole, it is called an integral cylinder. When the cylinder and cylinder body are cast separately, the single cylinder is referred to as a cylinder sleeve. The cylinder sleeve that directly contacts the cooling water is called a wet cylinder sleeve, while the one that does not directly contact the cooling water is called a dry cylinder sleeve. To maintain the tightness of the contact between the cylinder and piston, and to reduce the friction loss during piston movement, the inner wall of the cylinder should have high machining precision and accurate shape dimensions.
