Spain hydraulic cylinder,hydraulic gate cylinder manufacturer,hydraulic gate cylinder(Spain hydraulic gate cylinder,produced by Hengyu Hydraulic Co., Ltd)
hydraulic gate cylinder are widely used in Spain,because of excellent fatigue and impact resistance,long service life,simple structure and reliable operation.So our company has designed hydraulic gate cylinder for customers from Spain.
The piston seal of the hydraulic gate cylinder is the main element to prevent leakage in the hydraulic gate cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.
When installing the piston rod, 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 hydraulic gate cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
The commonly used buffer structure of the hydraulic gate cylinder is composed of a piston boss and a hydraulic gate cylinder head groove. When the piston moves close to the hydraulic gate cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.
In order to ensure the service life of the hydraulic gate cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the hydraulic gate cylinder, causing damage to the seal and causing leakage in the hydraulic gate cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.
What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
What is the difference between single acting hydraulic cylinder and double acting hydraulic cylinder?
Single action hydraulic cylinder is a single direction force work, the return of the plunger depends on itself or the weight of the mechanism to return. The double acting hydraulic cylinder is mainly different from the extension and retraction of the piston (the thrust and tension of the saying), which are all operated by the action of liquid pressure.
