Hydraulic cylinder failure, the most problematic is that bad judgment is when foreign matter into the hydraulic tank. After entering a foreign body, the outer surface of the piston slide where fitted with lip seals, then lip seals work to scrape foreign body, it is advantageous to avoid scratches. But loading 0-ring piston cylinder production factory, which ends the sliding surface, foreign matter is sandwiched between the sliding surface, easy to form scars. Way foreign matter into the cylinder are the following. Commonly used in hydraulic cylinder cushioning device has an adjustable choke and throttle change type two high-pressure cylinder, orifice change the formula was sealed by the needle in the oil throttle piston and the cylinder head between the outflow throttle valve opening can be adjusted according to the load, a large initial buffering effect, as the piston travels, the cushioning effect gradually weakened, so the brake stroke length, cushion the impact of the chamber pressure, oil temperature influence by cushioning properties for a wide range . Hydraulic cylinders are generally by the cylinder, the cylinder rod and seals composed by the piston inside the cylinder is divided into two parts hydraulic engineering, respectively, through a hole. The compression ratio of the liquid is very small, so when one hole into the oil, the piston will be pushed to make another hole oil, piston rod drive do extend (retract) movement, and vice versa. Anqing cylinders, large-tonnage hydraulic cylinders, Hydraulic Lu (certified merchants) are provided by the Texas Lu of the hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) strong, credible, in Dezhou hydraulic machinery and components industry has accumulated a large number of loyal customers.
