(Nigeria tension cylinder,produced by Hebei Hengyu company）

tension cylinder are widely used in Nigeria，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed tension cylinder for customers from Nigeria.

Introduction to tension cylinder:

The definition of the minimum starting pressure of the tension cylinder refers to the minimum working pressure of the tension cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the tension cylinder parts and the size of the sealing friction.

tension cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

If the tension cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the tension cylinder. The internal parts of the tension cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the tension cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the tension cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the tension cylinder bore processing is out of whack. Because the piston and tension cylinder, guide rail and piston rod are relative If the tension cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling tension cylinder weight composition and calculation. The weight of the tension cylinder is composed of the tension cylinder diameter, the outer diameter and weight of the tension cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

The body of the tension cylinder on the processing process requirements: the body of the tension cylinder is an important and essential part of the tension cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the tension cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about tension 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 rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.
