Puerto Rico self-locking hydraulic cylinder

(Puerto Rico self-locking hydraulic cylinder,produced by Hebei Hengyu company)

self-locking hydraulic cylinder are widely used in Puerto Rico,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed self-locking hydraulic cylinder for customers from Puerto Rico.

Introduction to self-locking hydraulic cylinder:

The viscosity of the working oil used in the self-locking hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

Most of the failure of the self-locking hydraulic cylinder is because there is a foreign body in the self-locking hydraulic cylinder into the failure of the self-locking hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the self-locking hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

If the self-locking hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

The coordination of the sliding parts of the self-locking hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

Answers to some questions about self-locking hydraulic cylinder:

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.

Why the injection cylinder retreating after the injection molding machine is started?
It is likely that the projected area of the molded plastic parts is large or the injection pressure set is relatively large, resulting in the expansion force exceeding the clamping force of the injection molding machine, so the mold is backward. You can do the following attempts: 1, reduce the injection force of the injection molding machine; 2, if the injection molding part can not be well formed by reducing the injection force, it is recommended to install the mold to a larger injection molding machine.
