India tension cylinder

(India tension cylinder,produced by Hengyu Hydraulic Co., Ltd)

tension cylinder are widely used in India,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed tension cylinder for customers from India.

Introduction to tension cylinder:

If it is found that the tension cylinder lubrication is poor or the tension cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the tension cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the tension cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the tension cylinder center line. In this way, when the piston works in the tension cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the tension cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

At the rated pressure, the thrust of the tension cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the tension cylinder is related to the diameter of the tension cylinder, but not to the stroke of the tension cylinder. Moreover, the larger the tension cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the tension cylinder.

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.

tension cylinder is the most important part of construction machinery, the traditional processing method is: broaching tension cylinder block - fine boring tension cylinder block - grinding tension cylinder block. The rolling method is: broaching tension cylinder block - fine boring tension cylinder block - rolling tension cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the tension cylinder block is about 1-2 days, rolling 1 meter of the tension cylinder 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 RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the tension cylinder increases by 25%. If the tension cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality tension cylinders, you must take the rolling production process. After the tension cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about tension cylinder:

What is a hydraulic cylinder assembly?
Assembly, which means aggregate. A series of parts or products, formed to achieve a specific function of the whole, the general term for this system is assembly. The hydraulic cylinder assembly is not a single hydraulic cylinder part, which can be used by connecting the hydraulic hose.

How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.
