Greece hydraulic cylinder,punch machine hydraulic cylinder manufacturer,punch machine hydraulic cylinder(Greece punch machine hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
punch machine hydraulic cylinder are widely used in Greece,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed punch machine hydraulic cylinder for customers from Greece.
When the punch machine hydraulic cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the punch machine hydraulic cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
Regular maintenance of the punch machine hydraulic cylinder includes: regular tightening, punch machine hydraulic cylinder fastening screws and gland screws, punch machine hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the punch machine hydraulic cylinder once a year. Clean regularly, the punch machine hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.
Because of the slightly complex structure of the buffer punch machine hydraulic cylinder, sometimes there will be problems, such as when the punch machine hydraulic cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.
When the oil pressure of the punch machine 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.
Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.
Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
