(Uganda cargo elevator hydraulic cylinder,produced by Hengyu Group）

cargo elevator hydraulic cylinder are widely used in Uganda，because of smooth movement，no need for deceleration device，long service life.So our company has designed cargo elevator hydraulic cylinder for customers from Uganda.

Introduction to cargo elevator hydraulic cylinder:

The cargo elevator hydraulic cylinder should be vented: when the cargo elevator hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the cargo elevator hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the cargo elevator hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the cargo elevator hydraulic cylinder, the oil is best entered and discharged from the highest point of the cargo elevator hydraulic cylinder. cargo elevator hydraulic 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.

The method of sleeve cargo elevator hydraulic cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the cargo elevator hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the cargo elevator hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

The scar on the sliding surface of the cargo elevator hydraulic 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 cargo elevator hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

The cargo elevator hydraulic cylinder is mainly composed of body, piston, piston rod, cargo elevator hydraulic cylinder head, cargo elevator hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the cargo elevator hydraulic cylinder into two chambers, and moves reciprocally in the cargo elevator hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the cargo elevator hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the cargo elevator hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the cargo elevator hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the cargo elevator hydraulic cylinder bottom and the cargo elevator hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the cargo elevator hydraulic cylinder The working medium of the cargo elevator hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; cargo elevator hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the cargo elevator hydraulic cylinder: The buffer structure of the cargo elevator hydraulic cylinder is to prevent the piston from colliding with the cargo elevator hydraulic cylinder head at the end of the stroke.

Answers to some questions about cargo elevator hydraulic cylinder:

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.

What is the difference between hydraulic cylinder self-adjusting buffer and adjustable buffer?
If it is the buffer device inside the cylinder, then there are 4 basic forms, cylindrical buffer device, conical buffer device, variable throttle and adjustable flow groove. The biggest difference between the first three and the latter is that the latter can be adjusted through the external thimble to change the buffer strength, the first three mainly rely on the buffer device and buffer groove form to achieve the buffer (among them, the first type of buffer strength will not change, and the buffer strength of the two and three forms of buffer devices can be gradually increased).
