(Thailand supporting cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to supporting cylinder:

The supporting cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the supporting cylinder, bite. Elimination method: When installing the supporting cylinder, ensure that the axis position of the supporting cylinder is consistent with the direction of movement; Make the load borne by the supporting cylinder as far as possible through the supporting cylinder axis, to avoid the phenomenon of eccentricity.

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

When the supporting cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the supporting cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil supporting cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical supporting cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the supporting cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

How to determine the working pressure of the supporting 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, supporting 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 supporting cylinder:

A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.

What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
