Slovakia hydraulic cylinder,cylinder with sensor manufacturer,cylinder with sensor

(Slovakia cylinder with sensor,produced by Hengyu Hydraulic Cylinder Factory）

cylinder with sensor are widely used in Slovakia，because of excellent fatigue and impact resistance，long service life，no need for deceleration device.So our company has designed cylinder with sensor for customers from Slovakia.

Introduction to cylinder with sensor:

cylinder with sensor 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 cylinder with sensor seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the cylinder with sensor. c. The cylinder with sensor seal is extruded, if the O-ring is obviously extruded at the cylinder with sensor seal, replace the cylinder with sensor seal.

When the cylinder with sensor is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the cylinder with sensor seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

The cylinder with sensor should be vented: when the cylinder with sensor is installed or parked for a long time to work again, the air will penetrate into the cylinder with sensor and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the cylinder with sensor and the system should be discharged. In order to facilitate the removal of air deposited in the cylinder with sensor, the oil is best entered and discharged from the highest point of the cylinder with sensor. cylinder with sensors that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the cylinder with sensor are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

Answers to some questions about cylinder with sensor:

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.

How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
