Saudi Arabia 100 ton hydraulic cylinder

(Saudi Arabia 100 ton hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

100 ton hydraulic cylinder are widely used in Saudi Arabia,because of excellent fatigue and impact resistance,long service life,simple structure and reliable operation.So our company has designed 100 ton hydraulic cylinder for customers from Saudi Arabia.

Introduction to 100 ton hydraulic cylinder:

The repair method of 100 ton hydraulic cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

What kind of process is used in the 100 ton hydraulic cylinder to make high-quality 100 ton hydraulic cylinder products: the body is the main component of the 100 ton hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The 100 ton hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the 100 ton hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the 100 ton hydraulic cylinder increases by 25%. If the service life of the 100 ton hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. 100 ton hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the 100 ton hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and 100 ton hydraulic cylinder are stuck or the 100 ton hydraulic cylinder is blocked. At this time, no matter how to manipulate, the 100 ton hydraulic cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the 100 ton hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Causes and countermeasures of oil 100 ton hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the 100 ton hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the 100 ton hydraulic cylinder is visibly scarred, the 100 ton hydraulic cylinder must be replaced. It can be pressurized at one end of the 100 ton hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most 100 ton hydraulic cylinder piston drift may not come from the 100 ton hydraulic cylinder, the above method to determine the 100 ton hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

If the 100 ton hydraulic 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 100 ton hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow 100 ton hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the 100 ton hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the 100 ton hydraulic cylinder includes the leakage caused by excessive wear of the 100 ton hydraulic 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 100 ton hydraulic cylinder, and the phenomenon of "pulling the 100 ton hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

Answers to some questions about 100 ton hydraulic cylinder:

What type of seal is the cylinder of shaft 50?
You won't know the exact model until you take it apart. Oil seals have O, Y, Yx, KYx, U, UN, UHS, YA, St, Gray, Yamagata, Lei type, etc. It is difficult to know what kind of oil seal the designer chooses. Cylinder oil seal installation method: 1. Receive a fixed number of oil seals. 2. From receiving the oil seal to assembly, it must be kept clean. 3. Before assembly, check the oil seal and measure whether the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The inner cavity size should be suitable for the outer diameter width of the oil seal. Check the lip of the oil seal for damage.

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.
