Norway hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Norway synchronous hydraulic cylinder,produced by Hengyu Group)
synchronous hydraulic cylinder are widely used in Norway,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed synchronous hydraulic cylinder for customers from Norway.
There are some honeycomb holes in the inner wall of the synchronous hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the synchronous hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the synchronous hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the synchronous hydraulic cylinder is targeted to prevent. Is very necessary.
synchronous hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the synchronous hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the synchronous hydraulic cylinder. c. The synchronous hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the synchronous hydraulic cylinder seal, replace the synchronous hydraulic cylinder seal.
When the oil pressure of the synchronous hydraulic cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
When the synchronous hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the synchronous hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the synchronous hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.
What size of hydraulic cylinder is needed for 200 tons pressure? The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate by the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the pressure level P (unit MPa) when working, then the thrust of the cylinder F push =3.14*R*R*P (unit N) the pull of the cylinder F pull =3.14* (R* R-R *R) *P (unit N) 100 tons of the cylinder, System pressure 16Mpa.
Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.
