Croatia cylinder with hydraulic lock

(Croatia cylinder with hydraulic lock,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to cylinder with hydraulic lock:

Before the cylinder with hydraulic lock is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

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

cylinder with hydraulic lock hydraulic oil selection: The recommended working oil viscosity of the cylinder with hydraulic lock is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

The cylinder with hydraulic lock should be used correctly and maintained regularly. The cylinder with hydraulic lock should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the cylinder with hydraulic lock should be cleaned regularly, and attention should be paid to waterproof and fireproof.

Answers to some questions about cylinder with hydraulic lock:

What are the requirements for hydraulic cylinder assembly? ① The installation of the cylinder should be solid and reliable. In order to prevent the influence of thermal expansion, in the case of large stroke and hot working conditions, one end of the cylinder must be kept floating.② pipe connection shall not be relaxed.③ The mounting surface of the hydraulic cylinder and the sliding surface of the piston rod should maintain sufficient parallelism and perpendicality.④ The central axis of the moving cylinder should be concentric with the center line of the load force, otherwise it will cause lateral force, which is easy to wear the seal And piston damage. The greater the distance between the supporting points of the piston rod, the smaller its wear. For the hydraulic cylinder of the moving object, the installation should keep the cylinder parallel with the moving object, and the degree of non-parallelism is generally not greater than 0.05mm/m. ⑤The sealing ring should not be installed too tightly, especially the U-shaped sealing ring.

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.
