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

        Introduction to large long cylinder:

        When installing the large long cylinder, the axial ends of the large long cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the large long cylinder, there is axial expansion. If the two ends of the large long cylinder are fixed, all parts of the large long cylinder will be deformed. When disassembling the large long cylinder, it is strictly forbidden to hammer the large long cylinder and the piston surface, such as the large long cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

        How to determine the working pressure of the large long 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, large long 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.

        In the process of using the large long cylinder, sometimes such a problem will occur, the large long cylinder can not act immediately after the instruction of the large long cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil large long cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

        When the large long cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the large long cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the large long cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

        Answers to some questions about large long cylinder:

        What does the maximum output force of the cylinder piston mean?
        The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.

        What is the material of the hydraulic cylinder slider?
        Three parts of the hydraulic cylinder are essential, which are: cylinder - cylinder head assembly, piston - piston rod assembly, and sealing device. When you say slider, you mean piston. - Piston rod. Piston materials commonly used gray cast iron, wear-resistant cast iron, aluminum alloy (assembled), etc., can also be used 35 and 45 steel (integral). The piston rod is generally made of 35 and 45 steel. When the impact vibration is large, alloy steel such as 55 steel or 40Cr is used.
