How much pressure can a cylinder withstand?
1 Answers
Cylinders can generally withstand a maximum pressure of 0.8 MPa. The pressure a cylinder can handle usually depends on the valve specifications - if the valve cannot withstand the pressure, the cylinder's capacity becomes irrelevant. The normal operating pressure range is 0.3-0.8 MPa. There are three main parameters that determine a cylinder's pressure capacity: the cylinder's inner diameter, the piston rod's diameter, and the working pressure applied. Below are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding components, thereby reducing wear. 2. Sealing: Engine oil forms a seal between piston rings and pistons, reducing gas leakage and preventing contamination. 3. Rust prevention: Lubricating oil adheres to component surfaces, protecting them from water, air, acidic substances, and harmful gases. 4. Cushioning: When cylinder pressure rises sharply, suddenly increasing the load on pistons, piston rings, connecting rods and crankshaft bearings, the lubricated bearing transmission helps cushion these impact loads. 5. Cleaning: Quality engine oil carries away carbon deposits, sludge, and metal wear particles through circulation back to the oil pan, cleaning component surfaces through oil flow.
