Tanzania hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder(Tanzania single rack cylinder,produced by Hengyu Hydraulic Co., Ltd)
single rack cylinder are widely used in Tanzania,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed single rack cylinder for customers from Tanzania.
The single rack cylinder should be vented: when the single rack cylinder is installed or parked for a long time to work again, the air will penetrate into the single rack cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the single rack cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the single rack cylinder, the oil is best entered and discharged from the highest point of the single rack cylinder. single rack cylinders 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.
Do not regularly check the damage of the chrome layer of the single rack cylinder: completely extend the single rack cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the single rack cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the single rack cylinder seal. Welding slag is strictly prohibited on the surface of the single rack cylinder.
When the long-stroke single rack cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in single rack cylinder head seal damage, oil leakage, and piston sleep in the single rack 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 single rack cylinder; The piston and the piston rod are connected with a spherical joint.
The scar on the sliding surface of the single rack cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the single rack cylinder wall. Therefore, before installation, these scars must be fully repaired.
What brand of hydraulic cylinder seal ring is best?
Depending on the specific product, the world famous seal brands are NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN and so on.
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.
