The chrome plated steel bar plays a very important role in the hydraulic system during its use. The transmission pressure, lubrication, cooling and sealing are all important parts of the piston rod. The use of hydraulic oil directly affects the early stage of the hydraulic system. The main cause of failure and its durability.
In the process of selecting the piston rod, we will select the appropriate piston rod for the hydraulic system. It should also be selected according to the specified grade in the piston rod instruction manual. In special cases, you should also strive to use the alternative oil that matches the performance of the original grade.
The clean hydraulic oil in the piston rod is the life source of the whole hydraulic system. In the stainless steel casting hydraulic system, many precision parts, some have gaps, some have damping holes, when the solid impurities in the metamorphic oil invade the piston rod, This will lead to a series of strains, hairpins, oil passage blockages, etc. that endanger the safe operation of the hydraulic system.
The way in which the piston rod produces these solid impurities is often caused by unclean hydraulic oil, unclean fueling tools, inadvertent refueling and maintenance, and desquamation of hydraulic components, so avoiding these problems must be effective from the source. Check and control.
The piston rod is selected in our daily practice to effectively clean and dry the piston and cylinder liner. Apply a layer of cleaning oil to the working surface, set the cylinder sleeve upright, the top of the piston is facing down, and the right hand is smooth. Put the ground into the cylinder liner. If the piston slowly falls, it indicates that the piston and the cylinder sleeve have a good clearance; if it does not fall, the clearance is too tight; if it falls too fast, it indicates that the clearance is too large.
The piston rod improves the corrosion resistance of the surface of the product during the operation, and can effectively delay the generation or expansion of the fatigue crack to a certain extent, and the rolling surface forms a cold hardening layer, which reduces the grinding pair. Elastic and plastic deformation of the contact surface.
