lifter hydraulic cylinder are widely used in Greece，because of long service life，smooth movement，high work efficiency.So our company has designed lifter hydraulic cylinder for customers from Greece.

Introduction to lifter hydraulic cylinder:

The definition of the minimum starting pressure of the lifter hydraulic cylinder refers to the minimum working pressure of the lifter hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the lifter hydraulic cylinder parts and the size of the sealing friction.

Classification of lifter hydraulic cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

When the lifter hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The lifter hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the lifter hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil lifter hydraulic cylinder should not be in direct contact with water vapor for a long time. The lifter hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the lifter hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the lifter hydraulic cylinder Before working, the lifter hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the lifter hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

How to determine the working pressure of the lifter hydraulic cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, lifter hydraulic cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

Answers to some questions about lifter hydraulic cylinder:

Cylinder la-50-70st What does that mean?
Full model should be CX-LA-50-70ST, thin block cylinder, radial mounting, bore 50, stroke 70.

What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
