(Spain tension cylinder,produced by Hengyu Hydraulic Cylinder Factory）
tension cylinder are widely used in Spain，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed tension cylinder for customers from Spain.
When the long-stroke tension cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in tension cylinder head seal damage, oil leakage, and piston sleep in the tension cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the tension cylinder; The piston and the piston rod are connected with a spherical joint.
The tension cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
The wear of the hard chromium plating layer of the tension cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
The tension cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the tension cylinder, bite. Elimination method: When installing the tension cylinder, ensure that the axis position of the tension cylinder is consistent with the direction of movement; Make the load borne by the tension cylinder as far as possible through the tension cylinder axis, to avoid the phenomenon of eccentricity.
How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
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.
