Composed of structural engineering machinery hydraulic seal repair kits in general, engineering machinery seal repair kits by the O-ring seal hole, seal, dust ring these component parts, as follows: 1, hole closure: Common The V-shaped ring, U-ring, Grameen ring, seals and other combinations, namely: V-ring hole, hole Grameen circle, hole U-ring, V-ring seals in combination generally used in heavy contained hydraulic cylinder design and manufacture of non-standard fuel tank, reliable sealing, usually in pairs back to back installation, open trenches. With this type of seal their guide elements commonly used copper sleeve. Application of U-shaped ring broadest, reliable sealing of non-standard fuel tank, a lot of this type of engineering cylinder seals and Water tanks are used. Can also be closed with open trench trench, which guide element is the use of a guide with a lot of Grameen ring is generally used in internal leakage requirements are not too high places, because the material slip rings which were powered by PTFE Sealing + more than 30% of copper, the material at low pressure leakage values ??within the larger 2, seal: a common V-rings, U-rings, seals, etc Manchester Manchester seal: This seal of applications widely, generally as a rod seal system first seal (ie, primary seal), the ring back to the oil that is leaking oil in the past can be brought back to retract the piston rod is very good. Generally requires the use of seals in combination with other U-ring: The sealing ring may be used alone, in the system working pressure not exceeding 20MPa situation can be used alone, more than 20MPa alone, then the general need to increase the retaining ring. V-ring: its use with the V-ring hole almost need to use open trenches, the guide element commonly used copper sleeve. 3, dust ring: a common double acting and single acting dust ring dust ring. We are the largest cylinder manufacturer in Texas, as Texas cylinder manufacturers on behalf of our time for users to solve difficult problems, and today we want to analyze the reasons for the three hydraulic cylinders made loud. 1, relief instability, such as due to the spool valve hole with improper contact with the valve seat or cone valve is stuck at the dirt clogging the orifice, such as the failure of the spring skew or jam or spool valve hole mobile working, causing the system pressure fluctuations and noise. 2, the valve to adjust properly, so valve spool moves too fast, resulting commutation impact, resulting in noise and vibration. 3, mechanical vibration, such as an elongated pipe, elbow without adding more fixed, in an oil circulation outdated cylinder, especially when the flow rate is high cylinder customized easily lead pipe jitter; rotating part of the motor and the unbalanced hydraulic pump, or for the poor at the time of installation, or loose coupling, etc., can produce vibration and noise. Cylinder prices, fuel tanks, hydraulic speed quality offered by mass-velocity Dezhou City, hydraulic machinery factory. Dezhou City mass-velocity hydraulic machinery plant (www.dzzhisu.com) (www.dzzhisu.com) strong, credible, in Dezhou hydraulic equipment industry has accumulated a large number of loyal customers.
