magnetic ring induction cylinder are widely used in Sri Lanka，because of long service life，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed magnetic ring induction cylinder for customers from Sri Lanka.

Introduction to magnetic ring induction cylinder:

What kind of process is used in the magnetic ring induction cylinder to make high-quality magnetic ring induction cylinder products: the body is the main component of the magnetic ring induction 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 magnetic ring induction 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 magnetic ring induction 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 magnetic ring induction cylinder increases by 25%. If the service life of the magnetic ring induction 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. magnetic ring induction 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 magnetic ring induction 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 magnetic ring induction cylinder are stuck or the magnetic ring induction cylinder is blocked. At this time, no matter how to manipulate, the magnetic ring induction 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 magnetic ring induction cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The magnetic ring induction cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

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

When the magnetic ring induction cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Answers to some questions about magnetic ring induction cylinder:

What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.

Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
