(Vietnam tension cylinder,produced by Hebei Hengyu company）

tension cylinder are widely used in Vietnam，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed tension cylinder for customers from Vietnam.

Introduction to tension cylinder:

Classification of tension 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.

If the tension cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the tension cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow tension cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the tension cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the tension cylinder includes the leakage caused by excessive wear of the tension cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and tension cylinder, and the phenomenon of "pulling the tension cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The difference between the integral tension cylinder and the split tension cylinder: The integral tension cylinder and the split tension cylinder in the tension cylinder are two different tension cylinders, and they are very different. The whole tension cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split tension cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and tension cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

tension cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

Answers to some questions about tension cylinder:

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.

Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.
