Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cylinder lubrication, in particular to a piston cylinder lubricating device. BACKGROUND

[0002] The lubricating device of the piston cylinder is a key component to ensure its efficient and stable operation. There is high-frequency relative motion between the piston and the cylinder wall, and between the piston ring and the cylinder wall. The lubricating device delivers lubricating oil to the friction surface to form an oil film. This oil film can separate the metal surfaces and reduce the wear of the parts, thereby prolonging the service life of the cylinder, piston and piston ring. The piston cylinder lubricating device directly affects the operation efficiency, service life and reliability of the equipment through four core functions of lubrication, sealing, cooling and corrosion prevention. It is an indispensable component of piston machinery. In different application scenarios, the type of lubricating device and the selection of lubricating oil will also be adjusted according to the needs to ensure the best results.

[0003] The existing Chinese patent number CN107477045A, "Piston Cylinder Lubricating Device", discloses a piston cylinder lubricating device, which includes a cylinder body, a piston, a piston rod, a piston fixing block, a rotating shaft, a motor, a rotating shaft fixing column, an air inlet, an air outlet and an air duct. The bottom of the cylinder body is provided with an oil storage cavity. An elastic sleeve is spirally fixed between the piston fixing block and the oil storage cavity. The piston fixing block and the oil storage cavity are connected through the elastic sleeve. An integrated duct is arranged in the piston, the piston rod and the piston fixing block. An oil absorbing cotton is arranged in the oil storage cavity and extends into the duct to fill the entire duct. The piston cylinder lubricating device can lubricate the piston and the cylinder body while the piston is moving in the cylinder. It does not need external addition, simplifies the oiling method, and avoids leakage or insufficient output caused by insufficient lubricating oil supply.

[0004] However, the above-mentioned scheme does not set the oil injection amount structure according to the engine speed, and cannot accurately match the lubrication demand under different working conditions. If the oil injection amount is fixed and designed according to high-speed requirements, excessive lubricating oil will be produced at low speed, which will be burned, resulting in carbon deposition, reducing engine efficiency, and even causing knock. The unburned lubricating oil will be discharged with the exhaust gas, increasing the exhaust pollutants. When the engine runs at high speed, the relative speed between the piston and the cylinder wall increases significantly, the friction increases, and the heat generated increases sharply. Insufficient lubricating oil flow cannot carry away more heat to assist in cooling the friction parts, resulting in material failure caused by local overheating, increasing the risk of overheating, and unable to ensure sufficient lubrication at high speed to reduce wear and cope with high temperature, ultimately achieving high efficiency, durability and environmental protection of the engine.
